Abstract:

Nelumbo nucifera (Gaertn.), commonly known as the lotus, is an aquatic plant native to India and presently consumed as food, mainly in China and Japan. In addition to its use as food, the lotus plant is also widely used in Indian and Chinese traditional medicine. Extracts from different parts of the lotus plant have been reported to show several biological activities, such as antioxidant, free radical scavenging, anti-inflammatory, and immuno-modulatory activities. Despite this, little work has been done in isolating and identifying the proteins responsible for these activities. To date, there is no report on systematic protein analysis of the lotus plant. In this review, we discuss the medicinal value of the lotus plant and reported works on its biological activities. We also present a proteomics approach for systematic investigation of the lotus seed proteome. DOI: http://dx.doi.org/10.3126/ijls.v7i1.6394 International Journal of Life Sciences 7(1): 2013; 1-5

Abstract:

Abstract The effect of soil volume on containerized lotus (Nelumbo) production has been underreported. American lotus (Nelumbo lutea Willd.) and three cultivars (‘Embolene’, ‘98 Seed’ and ‘Karizma’) of Asian lotus (N. nucifera Gaertn.) were investigated for growth response to container soil volume in this study. Electrical conductivity, pH, plant growth indices, and plant nutritional content were influenced by container soil volume. Differences in some plant growth indices were significant between treatments with ½ and higher (½ and ¾) container height soil (CHS) in 21 or 29 liter (#5 or #7) containers. However, plant growth indices were generally not different between treatments with ½ and ¾ CHS. Lotus planted in containers with ¼ CHS usually produced the greatest plant height and underground fresh weight, while the largest number of propagules often occurred in containers with ½ or ¾ CHS. The highest number of emerging leaves was observed in plants with ¼ or ½ CHS treatments, with no significant difference in emerging leaf number between lotus grown in containers with ½ and ¾ CHS. Flower number generally decreased as soil level increased. The ¼ and ½ CHS were more efficient than ¾ CHS for lotus production in containers.

Abstract:

Lotus (120–130 species) is the largest genus of the tribe Loteae. The taxonomy of Lotus is complicated, and a comprehensive taxonomic revision of the genus is needed. We have conducted phylogenetic analyses of Lotus based on nrITS data alone and combined with data on 46 morphological characters. Eighty-one ingroup nrITS accessions representing 71 Lotus species are studied; among them 47 accessions representing 40 species are new. Representatives of all other genera of the tribe Loteae are included in the outgroup (for three genera, nrITS sequences are published for the first time). Forty-two of 71 ingroup species were not included in previous morphological phylogenetic studies. The most important conclusions of the present study are (1) addition of morphological data to the nrITS matrix produces a better resolved phylogeny of Lotus; (2) previous findings that Dorycnium and Tetragonolobus cannot be separated from Lotus at the generic level are well supported; (3) Lotus creticus should be placed in section Pedrosia rather than in section Lotea; (4) a broad treatment of section Ononidium is unnatural and the section should possibly not be recognized at all; (5) section Heinekenia is paraphyletic; (6) section Lotus should include Lotus conimbricensis; then the section is monophyletic; (7) a basic chromosome number of x = 6 is an important synapomorphy for the expanded section Lotus; (8) the segregation of Lotus schimperi and allies into section Chamaelotus is well supported; (9) there is an apparent functional correlation between stylodium and keel evolution in Lotus.

Abstract:

Lotus (Nelumbo) is a highly valued plant with a long history for vegetable, ornamental, and medicinal use. Little information is available on the effects of planting time on performance of lotus, especially when grown in containers. The objectives of this study were to find a suitable planting time and to determine best management practices that are of importance for container lotus production. Effects of planting time and disbudding on plant growth indices in southeast Alabama were evaluated in a container production system for the ornamental lotus, N. nucifera ‘Embolene’. Results indicated that plant growth indices were little influenced by different planting dates in March, but were much influenced by planting dates with a difference over a month between February and May. Plants potted and placed outdoors in March and April performed best, and lotus planted in the greenhouse in February and planted outdoors in February and May performed worst. Flower number was not largely influenced by the planting time, but flowering characteristics, especially the flowering peaks, were different among treatments. Planting lotus outdoors between March and May produced the largest return. Influence of planting time on plant growth indices of lotus appeared to be explained by effects of growth-season climate conditions after planting. Disbudding had no impact on plant height but significantly increased underground fresh weight and the number of propagules. Therefore, disbudding should be considered a best management practice to maximize the yield of rhizomes or propagules. Positive linear, quadratic, or cubic relationships were detected among emerging leaf number, underground fresh biomass, and propagule number. Based on the regression models, the yield of lotus rhizomes or propagules can be predicted by the number of emerging leaves. This research provided a guide for nurseries, researchers, and collectors to select the best time to plant lotus outdoors.

Abstract:

The diagnostic characters of the genus Lotus L. are a claw with a thickened infolded margin, diadelphous stamens, and a style hardened from the base. This genus contains about 100 species that are distributed throughout the world. To investigate the phylogeny of the Old World species of Lotus, subgenus Edentolotus, sections Krokeria, Xantholotus, and Erythrolotus, a cladistic analysis was performed using 31 morphological characters. To test the phylogenetic relationships among species of Lotus-Edentolotus and Dorycnium, Pedrosia, and Tetragonolobus, these taxa were included as part of the ingroup. The polarity of the characters was based on the outgroup comparison method, using Anthyllis as one outgroup and Tripodion as another. The analysis with Anthyllis as outgroup yielded eight equally parsimonious trees (with all characters equally weighted), each with 62 steps, a consistency index of 0.53, and a retention index of 0.75. All trees (including the strict consensus tree from the eight initial trees) showed that genus Lotus, subgenus Edentolotus, and sections Xantholotus and Erythrolotus are polyphyletic, with only section Krokeria appearing as monophyletic. On the other hand, the groups of species Lotus angustissimus, Lotus corniculatus, Lotus creticus, and Lotus peregrinus are monophyletic. Identical results were derived from the data matrix using Tripodion as the outgroup. Results are compared with previous cytogenetic and biochemical evidence.Key words: cladistic analysis, Fabaceae, Loteae, Lotus, Old World species, phylogeny.

Abstract:

Lotus (Nelumbo nucifera) is a perennial aquatic basal eudicot belonging to a small family Nelumbonaceace, which contains only one genus with two species. It is an important horticultural plant, with its uses ranging from ornamental, nutritional to medicinal values, and has been widely used, especially in Southeast Asia. Recently, the lotus obtained a lot of attention from the scientific community. An increasing number of research papers focusing on it have been published, which have shed light on the mysteries of this species. Here, we comprehensively reviewed the latest advancement of studies on the lotus, including phylogeny, genomics and the molecular mechanisms underlying its unique properties, its economic important traits, and so on. Meanwhile, current limitations in the research of the lotus were addressed, and the potential prospective were proposed as well. We believe that the lotus will be an important model plant in horticulture with the generation of germplasm suitable for laboratory operation and the establishment of a regeneration and transformation system.

Abstract:

Sacred lotus (Nelumbo nucifera Gaertn.) is an ancient aquatic plant used throughout Asia for its nutritional and medicinal properties. Benzylisoquinoline alkaloids (BIAs), mostly within the aporphine and bisbenzylisoquinoline structural categories, are among the main bioactive constituents in the plant. The alkaloids of sacred lotus exhibit promising anti-cancer, anti-arrhythmic, anti-HIV, and anti-malarial properties. Despite their pharmacological significance, BIA metabolism in this non-model plant has not been extensively investigated. In this review, we examine the diversity of BIAs in sacred lotus, with an emphasis on the distinctive stereochemistry of alkaloids found in this species. Additionally, we discuss our current understanding of the biosynthetic genes and enzymes involved in the formation of 1-benzylisoquinoline, aporphine, and bisbenzylisoquinoline alkaloids in the plant. We conclude that a comprehensive functional characterization of alkaloid biosynthetic enzymes using both in vitro and in vivo methods is required to advance our limited knowledge of BIA metabolism in the sacred lotus.

Abstract:

The morphology of Rhizobium loti induced root nodules and the flavolan content of nodulated roots of several Lotus species, Leuceana leucocephala, Carmichaelia flagelliformis, Ornithopus sativus, and Clianthus puniceus were examined. Rhizobium loti strain NZP2037 formed effective (Nod+Fix+) nodules on all legumes, but strain NZP2213 formed Nod+Fix+ nodules only on Lotus corniculatus var. cree and ineffective (Nod+Fix−) nodules on all other legumes. The Nod+Fix− nodules developed by NZP2213 showed morphologies ranging from the complete absence of bacteria within “tumour-like” structures to the development of nodules containing bacteria that were either not released or only incompletely released from infection threads. Within nodules formed by NZP2213 on Lotus corniculatus var. hirsutus and Carmichaelia flagelliformis the rhizobia had multiplied extensively within unwalled, plasma membrane bound, infection droplets. Flavolans rich in prodelphinidin, which is toxic towards NZP2213, were present in the roots of Lotus angustissimus, Lotus pedunculatus, Lotus subbiflorus, and Leuceana leucocephala, but only trace amounts of flavolan were found in the roots of Carmichaelia flagelliformis, Ornithopus sativus, and Clianthus puniceus.

Abstract:

The water lotus, genusNelumbo, contains two species, the sacred (Nelumbo nucifera) and American lotuses (Nelumbo lutea). Hundreds of flowering lotus cultivars are currently known. However, their classification is unclear. For the classification ofNelumbocultivars, in addition to 35 simple sequence repeat (SSR) markers recently developed, we have developed 17 and 16 of newNelumboSSR markers from SSR-enriched genomic libraries and expressed sequence tag (EST) data, respectively. Out of these 68 SSRs, along with SSRs recently published by others, 52 showed clear polymorphisms in 98Nelumbosamples. A total of 300 alleles were observed, ranging from 2 to 11 alleles per locus, with an average of 5.77. Alleles specific for the American lotus-derived cultivars and a cluster of the American lotus-derived cultivars on a neighbour-joining tree confirmed genetic differences betweenN. luteaandN. nucifera. In addition, a possible differentiation between Chinese and Japanese cultivars was also suggested. Parentage analysis using the SSR markers confirmed four known parentages and predicted currently-unknown parentages of six cultivars. The present data have demonstrated that site-specific, co-dominant SSR markers enable more accurate classification, identification and comparison ofNelumbospecies.

Abstract:

Lotus (Nelumbo nucifera Gaertn.) is an economically important aquatic plant with multiple applications, but water salinity and cold stress seriously affect lotus yield and distribution. The basic helix-loop-helix (bHLH) transcription factors (TFs) play a vital role in plant growth and development, metabolic regulation processes and responses to environmental changes. However, systematic analyses of the bHLH TF family in lotus has not yet been reported. Here, we report the identification and description of bHLH genes in lotus (NnbHLHs) with a focus on functional prediction, particularly for those involved in stress resistance. In all, 115 NnbHLHs were identified in the lotus genome and classified into 19 subfamilies. The chromosomal distribution, physicochemical properties, bHLH domain, conserved motif compositions and evolution of these 115 NnbHLHs were further analyzed. To better understand the functions of the lotus bHLH family, gene ontology, cis-element, and phylogenetic analyses were conducted. NnbHLHs were predicted to be involved in plant development, metabolic regulation and responses to stress, in accordance with previous findings. Overall, 15 NnbHLHs were further investigated with functional prediction via quantitative real-time PCR analyses. Meanwhile, expression profiles of NnbHLHs in four tissues indicated that many NnbHLHs showed tissue preference in their expression. This study is supposed to provide a good foundation for further research into the functions and evolution of NnbHLHs, and identifies candidate genes for stress resistance in lotus.

Abstract:

In the plain-lake area of south China, aquaculture and plantation of aquatic commercial crop are very common. In order to realize water quality improvement for aquaculture pond and reuse of the nutrients, it is essential to establish an integrated system that constitute aquaculture pond and plant purifying pond which are linked by necessary farmland works. In the study, the connection between fishpond and lotus pond was established mainly by water pipe and water suction pump. When lotus pond is used for purifying fishpond water, using water pump draw water from fishpond into lotus pond, then experiments of water retention and subsurface flow on the lotus pond were done in the several growth stages of lotus root. During the experiments taking water samplings at the inlet and outlet which were installed at lotus pond to determine the relevant water quality indicators, analysis showed that: TP, TN, NH4+-N, NO3――N, NO2――N and CODMn contained in aquaculture water may effectively remove as the water stay at lotus pond for a certain time, the removal rate of the above-mentioned substances increases with the increase of retention period of the aquaculture water standing in lotus pond; there are some regularity when fishpond water is purified by surface flow in lotus pond, the removal rate for TP and TN in dormant stage of lotus root is more than that in adult-plant stage and the effect in adult-plant stage is more than that in rooting stage, and for NH4+-N, NO3――N, NO2――N and CODMn the removal rate in adult-plant stage is more than that in dormant stage and the effect in dormant stage is more than that in rooting stage; the more of the TP, TN, NO3――N and NH4+-N is removed with the increase of the running time when fishpond water processed by surface flow in lotus pond, the removal rate of them arrives to 13.89%, 11.43%, 11.02% and 5.73% separately after the system running for 6 hours; compared with the contrast fishpond, the water quality of the fishpond combining with lotus pond is good obviously, where water quality indicators such as TP, NO3--N, TURB(turbidity) and SD(water transparency) arrive to significant improvement, meanwhile TN, NH4+-N and CODMn get a marked improvement. On average, such a conclusion can be drawn that aquaculture in fishpond and plantation in lotus pond may be integrate, fishpond water may get an improvement by ex-situ purification of lotus pond, and meanwhile the combination makes it possible that the nutrients contained in fishpond water are recycled.

Abstract:

Lotus glaber Mill. is a herbaceous legume, tolerant to flooding, that in a few decades has colonised the Flooding Pampa grasslands, an extensive wetland of 90 000 km in central-east Argentina. In this study, the growth and nodulation of flooded plants in 5 local populations were evaluated. Thirty-day-old seedlings, grown in pots, were flooded outdoors during 4 months. Stem, leaf, and root biomass, as well as the number of nodules per plant, were lower in flooded plants than in non-flooded ones. In flooded plants, the submerged portions of stems were hypertrophied and populations differed in the proportion of plants with adventitious roots. Flood tolerance was significantly related to the proportion of plants with adventitious roots in stems of each population. A positive relationship was shown between the proportion of plants with adventitious root and number of nodules per plant. The plants were also tolerant of low temperatures and ice-sheeting of water. These results underline the importance of morphological adaptations related to the maintenance of plant functionality under flooding conditions. The results provide evidence of the existence of characters related to flooding tolerance, which should be taken into account in ecological studies and agronomic selection programs

Abstract:

The first quantitative trait locus (QTL) analysis of multiple agronomic traits in the model legume Lotus japonicus was performed with a population of recombinant inbred lines derived from Miyakojima MG-20 × Gifu B-129. Thirteen agronomic traits were evaluated in 2004 and 2005: traits of vegetative parts (plant height, stem thickness, leaf length, leaf width, plant regrowth, plant shape, and stem color), flowering traits (flowering time and degree), and pod and seed traits (pod length, pod width, seeds per pod, and seed mass). A total of 40 QTLs were detected that explained 5%–69% of total variation. The QTL that explained the most variation was that for stem color, which was detected in the same region of chromosome 2 in both years. Some QTLs were colocated, especially those for pod and seed traits. Seed mass QTLs were located at 5 locations that mapped to the corresponding genomic positions of equivalent QTLs in soybean, pea, chickpea, and mung bean. This study provides fundamental information for breeding of agronomically important legume crops.

Abstract:

The GRAS gene family is one of the most important plant-specific gene families, which encodes transcriptional regulators and plays an essential role in plant development and physiological processes. The GRAS gene family has been well characterized in many higher plants such asArabidopsis, rice, Chinese cabbage, tomato and tobacco. In this study, we identified 38 GRAS genes in sacred lotus (Nelumbo nucifera), analyzed their physical and chemical characteristics and performed phylogenetic analysis using the GRAS genes from eight representative plant species to show the evolution of GRAS genes inPlanta. In addition, the gene structures and motifs of the sacred lotus GRAS proteins were characterized in detail. Comparative analysis identified 42 orthologous and 9 co-orthologous gene pairs between sacred lotus andArabidopsis, and 35 orthologous and 22 co-orthologous gene pairs between sacred lotus and rice. Based on publically available RNA-seq data generated from leaf, petiole, rhizome and root, we found that most of the sacred lotus GRAS genes exhibited a tissue-specific expression pattern. Eight of the ten PAT1-clade GRAS genes, particularly NnuGRAS-05, NnuGRAS-10 and NnuGRAS-25, were preferentially expressed in rhizome and root. In summary, this is the firstin silicoanalysis of the GRAS gene family in sacred lotus, which will provide valuable information for further molecular and biological analyses of this important gene family.

Abstract:

Lotus corniculatus, birdsfoot trefoil, is a Eurasian perennial legume, popular in temperate climates for pasture or hay and silage production. Its ancestry is controversial. While innumerable studies of L. corniculatus and allied species have been published, comprehensive morphological, geographical, and genetic studies are still needed. Nevertheless, there is sufficient information for a provisional analysis of the origin and relationships of this important economical species. Although sometimes defined to have diploid populations, L. corniculatus essentially appears to be tetraploid. Biochemical and genetic evidence indicates that this species is an allotetraploid. Although about a dozen diploid species have been proposed as ancestral to L. corniculatus, the evidence points strongly to four of these species. Lotus uliginosus uniquely shares a rhizomatous habit, an acyanogenic factor, and a tannin characteristic with L. corniculatus, clearly showing an especially close relationship, and reflecting the possibility that it is one of two direct parental species. Principal candidates for a second parent include Lotus alpinus, Lotus japonicus, and Lotus tenuis. A phenetic analysis presented here accords well with the hypothesis favoured in this paper that L. corniculatus arose as a hybrid of L. tenuis and L. uliginosus. Cytogenetic evidence indicates that L. japonicus is especially closely related to L. corniculatus. Flower colour in the hybrids between L. uliginosus and L. tenuis suggest maternal inheritance and that L. tenuis could have been the female parent. An evolutionary sequence is suggested in which L. uliginosus hybridized with L. tenuis followed by introgression from L. alpinus and L. japonicus. Alternatively, a prototype of L. alpinus, L. japonicus, and L. tenuis could have been the female parent of L. corniculatus, based on evidence from maternal inheritance of flower colour intensity and interactions of Rhizobium strains. Keywords: polyploidy, hybridization, evolution, Lotus species, Fabaceae, birdsfoot trefoil, Lotus corniculatus.

Abstract:

The Nelumbo nucifera known as sacred lotus is an ornamental plant having medicinal possessions. Lotus seeds, which are currently the oldest known plant seeds, contain many functional constituents. The seeds have been widely used as both medicine and food. In the present studies, the nutrient composition of collected from two separate beels at Tarakanda, Mymensingh were determined. The nutrient composition was determined as moisture 17.727 (± 0.053), ash 9.49 (± 0.059), crude protein 16.563 (± 0.076), crude lipids 4.146 (± 0.038), crude fiber 7.755 (± 0.045), carbohydrate 44.042 (± 0.011). The results showed that lotus seeds contained a high content of moisture, crude protein, crude lipids, crude fiber, ash and carbohydrate. From this research, it found that lotus seeds were rich in crude protein and carbohydrate. The study may conclude that seeds could be incorporated in feed formulation as a source of nutrients. The present experiment may provide a guideline for the use of lotus seeds as human food. Asian Australas. J. Biosci. Biotechnol. 2020, 5 (3), 115-120

Abstract:

Lotus croniculatus belongs to Fabaceae family and grows in the temperate regions and grasslands of the countries of Africa and America. The plant is commonly known as common bird’s foot tree foil. The plant is a herb and appears to be clover plant. The flowers of the plant are used mainly to induce sleep and other effects that regard to brain and heart. The plant is used to reduce spasms in the digestive tract. The infusions that are diluted to certain extent are helpful to reduce the anxiety and insomnia and also to treat exhaustion. Inspite of the possession of lot of pharmacological activities, the plant is to be studied in a detailed manner for the toxicity also. Medicinal plants are known to cause low adverse effects and high potency. In the present investigation, the acute and chronic toxicity levels of the plant Lotus croniculatus extract of leaves was studied in laboratory animals. It is indicated that the animals did not show any change in behavior in acute toxicity and no mortality too. The extract also showed no signs of toxicity and change of values in the blood cells, liver enzymes and also kidney function tests were also normal at the dose of 2g/kg which denotes the safety of the plant in rats.

Abstract:

Effective root nodules formed on Lotus pedunculatus by Rhizobium loti NZP2037 and Bradyrhizobium sp. (Lotus) CC814s were examined by light and electron microscopy. NZP2037 nodules were larger than CC814s nodules as a result of a much thicker nodule cortex. The smaller CC814s nodules had a much larger infected zone and, consequently, larger volumes of infected cells, peribacteroid space, and host cytosol per nodule. As well, CC814s nodules demonstrated a significantly higher number of bacteria which typically contained prominent polar bodies and beta-polyhydroxybutyrate (PHB) granules. The bacteria of NZP2037 nodules lacked the polar bodies, but PHB deposits were occasionally observed. A correlated physiological study in which acetylene reduction was used to estimate nitrogen fixation showed CC814s nodules to be more active than NZP2037 nodules (Pankhurst, C. E., and D. B. Layzell. 1984. Physiol. Plant. 62(3) : 404–409.). This measured difference in nitrogen-fixing activity was considered due to the degree of infection and bacterial proliferation as well as differences in the carbon and nitrogen metabolism of the two nodule types. The significance of the structural observations and morphometric analyses and their relationship to differences in nitrogen fixation are discussed.

Abstract:

A chemical analysis of the polyphenolic patterns of diploid and tetraploid populations of Lotus corniculatus s.l. (Fabaceae) growing in the southern French Alps showed that diploids from Mont Ventoux and from Montagne de Lure belong to the same chemotype. On the other hand, tetraploids showed two different chemotypes. This paper suggests the following hypothesis about the evolution of Lotus corniculatus in this area since the last glaciation: diploids could be derived from a relic diploid population scattered by glaciation and restricted within very narrow areas, whereas the tetraploids originating from the diiploids were more competitive and radiated into larger areas cleared from ice. Key words: Lotus corniculatus, birdsfoot trefoil, Fabaceae, polyploidy, polyphenolic metabolism, evolution.

Abstract:

Lotus root, which is a water plant cherished by people in the Asian continent and some other parts of the world, is manually inspected for quality by experts to detect impurities. There is the need to update this inspection process in order to improve the quality and safety of lotus root. Machine vision systems and techniques are used for consistent, efficient, effective, and reliable inspection of images. The lotus root inspection system has been proposed to inspect the lotus roots for impurities. The detection algorithms use the size, shape, texture and color of the lotus root images as parameters to analyze the quality of lotus roots. The lotus root undergoes some processes before image acquisition and image processing. The camera and illumination used, in collaboration with the edge detection, and image segmentation techniques, efficiently and effectively exposed the impurities in the lotus root at a much faster rate. Also, it is less expensive compared to the traditional human inspections.

Abstract:

ABSTRACT Owing to the high degree of diversity of metabolite pools and complexity of spatial and temporal distributions within biological tissues, currently available methods for metabolite characterization face large challenges. In this study, the temporal and spatial distributions of the alkaloid components of the medicinal plant lotus (Nelumbo nucifera) were investigated over various growth phases. The results showed that alkaloid biosynthesis in lotus leaf is regulated by development and that there is maximum accumulation of alkaloids when the lotus leaf was completely expanded. Furthermore, alkaloid content tended to be stable in mature lotus leaves. However, there was significant variation in the alkaloid content of lotus leaves with different genotypes, suggesting that genetic background is an important factor that affects the temporal and spatial distributions of alkaloids in sacred lotus leaves. The dynamic contents of alkaloids during the growth and development of lotus leaves provide insight into basic biological differences when sampling.

Abstract:

AbstractPredispersal seed predation may have implications for plant population dynamics and the evolution of plant traits, but assessing the level of seed predation for an individual plant is not always straightforward. Seeds of Lotus corniculatus (Fabaceae) are often only partially eaten by a weevil seed predator, Apion loti. Samples of these seeds were tested for viability and subsequent seedling vigour. A large proportion of these damaged seeds were viable, and the resulting seedlings almost as vigorous as those from undamaged seeds. The ubiquity of these findings, and their ecological significance, is discussed.

Abstract:

The genus Nelumbo consists of two species, N. nucifera and N. lutea. N. nucifera is an ornamental and edible plant that is widely cultivated. Earlier studies of sacred lotus (N. nucifera) flowers focused mainly on morphology, phyllotaxis, leaf arrangements, and flower development. During the growing season, sacred lotus produces one foliage leaf at each node. Flower buds emerge from the abaxial side of the basal part of the foliage leaf. However, the number of blooming flowers is much less than the number of foliage leaves. Little is known concerning flower bud formation during lotus plant development. This is the first experimental study to reveal that every node has one flower bud even in the dormant shoot apex and that most of the formed flower buds aborted in the course of floral development. Our results suggest that flower bud formation of sacred lotus is independent of daylength. On the other hand, whether a formed bud reaches blooming may depend on environmental factors.

Abstract:

The present study has been undertaken in order to highlight the healing effect of Zizyphus lotus vegetable oil. The seeds of this plant contain an oil rate of 30%. The obtained results on the main elements composing the vegetable oil have shown that Zizyphus lotus vegetable oil has a low value of acidity index and it presents a not negligible degree of unsaturation. The value of the peroxide index of Zizyphus lotus vegetable oil is less than 10 which characterizes the most of conventional oils. Furthermore, the spectral analysis by gas chromatography has shown the presence of 53 majority and minority molecules. Thus, the evaluation of the healing activity of Z. lotus seed vegetable oil has demonstrated a highly significant effect against the negative control and silver sulfadiazine was used as conventional treatment for burns. Based on the obtained results, we can suggest that the oil extracted from the seeds of the studied plant could be used to cure wounds.

Abstract:

Lotus pedunculatus (greater lotus) and L. corniculatus (birdsfoot trefoil) are perennial forages with potential to improve the legume content of pastures in south-eastern Australia. A collection of 39 accessions of each species was grown at 3 localities to assess the degree of genetic and genotype locality interaction components of variance for herbage yield, plant height, and width, the rate of reproductive development, and condensed tannin concentration as a prelude to forming strategies for genetic improvement. Rhizome development in L. pedunculatus and seed yields in both species were recorded at a single locality. The genetic variance component for herbage yield, plant height, and condensed tannins was significant for all characters, whereas the genotype × locality variance component was generally of lower magnitude. Grouping of accessions by geographic origin revealed important associations between characters. These associations were supported by strong positive genetic correlations. In L. pedunculatus, Portuguese accessions combined high autumn herbage yield with a tall plant type, a sparsely rhizomatous growth habit, high seed yield, and high condensed tannins. In L. corniculatus, prostrate growth habit was associated with high condensed tannins in accessions from Spain but was associated with low condensed tannins in Russian accessions. Principal components analysis of data for geographic groups of L. pedunculatus showed a positive association between means and variances, suggesting that selection within groups should be effective in producing cultivars with high herbage yield and low condensed tannins. In L.corniculatus, the positive genetic correlation between herbage yield and plant height suggested that hybridisation and selection would be required to produce a cultivar that would be more persistent under grazing.

Abstract:

The plant-specific transcription factor family YABBY plays important roles in plant responses to biotic and abiotic stresses. Although the function of YABBY has been identified in many species, systematic analysis in lotus (Nelumbo nucifera) is still relatively lacking. The present study aimed to characterize all of the YABBY genes in lotus and obtain better insights into NnYABBYs in response to salt stress by depending on ABA signaling. Here, we identified nine YABBY genes by searching the whole lotus genome based on the conserved YABBY domain. Further analysis showed that these members were distributed on six different chromosomes and named from YABBY1 to YABBY9, which were divided into five subgroups, including YAB1, YAB2, YAB5, INO, and CRC. The analysis of cis-elements in promotors revealed that NnYABBYs could be involved in plant hormone signaling and plant responses to abiotic stresses. Quantitative real-time PCR (qRT-PCR) showed that NnYABBYs could be up-regulated or down-regulated by ABA, fluridone, and salt treatment. Subcellular localization indicated that NnYABBY4, NnYABBY5, and NnYABBY6 were mainly localized in the cell membrane and cytoplasm. In addition, the intrinsic trans-activity of NnYABBY was tested by a Y2H assay, which revealed that NnYABBY4, NnYABBY5, and NnYABBY6 are deprived of such a property. This study provided a theoretical basis and reference for the functional research of YABBY for the molecular breeding of lotus.

Abstract:

Antioxidants are compounds materials that can inhibit the rate of oxidation of other molecules or neutralize free radicals. Antioxidants can be obtained in synthetic or natural forms. Natural antioxidants can protect the human body from damage to active oxygen which can inhibit degenerative diseases and inhibit the production of fat and food. Natural antioxidants can be obtained from plants, one of which is the Blue Lotus Plant (Nymphaea Stellata Wild). To ensure the presence of antioxidants in this plant, the antioxidant activity was tested using the DPPH method. The DPPH method was used to determine the free radical scavenging activity of the Ethanol Extract of Blue Lotus Leaf (Nymphaea Stellata Wild). The positive control used was Ascorbic Acid. The IC50 value obtained for testing the antioxidant content of blue lotus leaf is 78.405 ppm ± 24.607. And Ascorbic Acid 2,238 ppm. It can be concluded that the antioxidant activity of Blue Lotus Leaf is not too different from the positive control of ascorbic acid. The antioxidant activity of blue lotus leaf was stated to be strong and ascorbic acid was stated to be very strong. Keywords: Antioxidant, Free radicals, DPPH

We analysed 9 local populations from the Volga River valley ranging from Ulyanovsk in the north to Volgograd in the south, as well as two local populations from Moscow and Lipetsk Provinces. Analyses of SSR markers using the STRUCRURE program divided the sample into three genetic clusters. Populations from Moscow and Lipetsk Provinces, and three local populations from the ‘locus classicus’ location of L. zhegulensis in Samara Province appeared to be the most genetically differentiated while all the other populations were variously genetically admixed. Low pairwise Fst values indicate low genetic differentiation of Lotus populations and the intraspecific nature of the revealed diversity. The nuclear and plastid DNA sequences analyzed yielded little information. Substitutions and indels revealed were mostly autapomorphies characteristic of separate specimens or small groups of specimens but not of populations. Our study enables to firmly conclude that Lotus populations from the right bank of the Volga River in vicinity of Zhiguli upland described as L. zhegulensis are weakly genetically differentiated from other populations of Lotus corniculatus s. l. and, hence, cannot be regarded as a separate species.

Abstract:

The WRKY family is one of the largest transcription factor (TF) families in plants and plays central roles in modulating plant stress responses and developmental processes, as well as secondary metabolic regulations. Lotus (Nelumbo nucifera) is an aquatic crop that has significant food, ornamental and pharmacological values. Here, we performed an overview analysis of WRKY TF family members in lotus, and studied their functions in environmental adaptation and regulation of lotus benzylisoquinoline alkaloid (BIA) biosynthesis. A total of 65 WRKY genes were identified in the lotus genome and they were well clustered in a similar pattern with their Arabidopsis homologs in seven groups (designated I, IIa-IIe, and III), although no lotus WRKY was clustered in the group IIIa. Most lotus WRKYs were functionally paired, which was attributed to the recently occurred whole genome duplication in lotus. In addition, lotus WRKYs were regulated dramatically by salicilic acid (SA), jasmonic acid (JA), and submergence treatments, and two lotus WRKYs, NnWRKY40a and NnWRKY40b, were significantly induced by JA and promoted lotus BIA biosynthesis through activating BIA biosynthetic genes. The investigation of WRKY TFs for this basal eudicot reveals new insights into the evolution of the WRKY family, and provides fundamental information for their functional studies and lotus breeding.
