Abstract:
Abstract The Brassica genotypes selected for the experiments were previously found to be resistant to various Plasmodiophora brassicae pathotypes (Pb). Their interaction with pathotypes Pb2, Pb3 and Pb9 isolated in Poland was studied, using macroscopic observation for the presence of root galls, microscopic observations of P. brassicae plasmodia in the root hairs and quantitative PCR for determination of the pathogen’s quantity in plant roots and growing media. Of the Brassica genotypes studied, only B. rapa var. capitata line AABBcc was fully resistant to all the Polish pathotypes of P. brassicae. Some of the other “clubroot-resistant” genotypes tested were resistant to selected pathotypes, e.g. Brassica napus var. rapifera ‘Wilhelmsburger’ to Pb 2 and Pb3, Brassica oleracea var. capitata ‘Kilaton F1’ to Pb2 and Brassica rapa subsp. pekinensis ‘Bilko F1’ to Pb3, but were susceptible to others. B. oleracea var. capitata ‘Bindsachsener’, B. oleracea var. acephala subvar. lacinata ‘Verheul’ and B. napus var. napus ‘Mendel F1’ were moderately to highly susceptible to all Polish P. brassicae pathotypes. These results show that the classification of virulence of P. brassicae pathotypes selected in various areas differs significantly toward the same Brasssica genotypes and puts in question the practical value of pathotype classification determined with differential sets for farmers and plant breeders. Our results showed that B. rapa var. capitata AABBcc line, B. napus var. rapifera ‘Wilhelmsburger’, B. oleracea var. capitata ‘Kilaton F1’, B. rapa subsp. pekinensis ‘Bilko F1’ could be considered in Brassica breeding programmes as a source of resistance to Polish P. brassicae isolates.

Abstract:
The non-expresser of pathogenesis related gene 1 (NPR1) has been an important component of the SA/JA mediated mechanism of defence in plants. Brassicas have been major group of crop plants that are facing huge yield losses due to biotic stresses especially through Alternaria blight caused by Alternaria brassicae. Among the plethora of proteins, the NPR1 protein coding gene has been emphasised upon and an attempt has been made to isolate NPR1 alleles from different brassica species. The sequences were annotated using FGENESH and a maximum-likelihood tree was constructed using NPR1 genes from cultivated and wild brassica and also NPR1 from other crops. Understanding the genome structure of NPR1 and tagging the resistance alleles to the genomic regions of NPR1 among all species of Brassica has been aimed at in the present study.

Abstract:
Light leaf spot, caused by Pyrenopeziza brassicae, is the most damaging disease problem in oilseed rape (Brassica napus) in the United Kingdom. According to recent survey data, the severity of epidemics has increased progressively across the UK, with yield losses of up to £160M per annum in England and more severe epidemics in Scotland. Light leaf spot is a polycyclic disease, with primary inoculum consisting of airborne ascospores produced on diseased debris from the previous cropping season. Splash-dispersed conidia produced on diseased leaves are the main component of the secondary inoculum. Pyrenopeziza brassicae is also able to infect and cause considerable yield losses on vegetable brassicas, especially Brussels sprouts. There may be spread of light leaf spot among different Brassica species. Since they have a wide host range and frequent occurrence of sexual reproduction, P. brassicae populations are likely to have considerable genetic diversity, and evidence suggests population variations between different geographic regions, which need further study. Available disease-management tools are not sufficient to provide adequate control of the disease. There is a need to identify new sources of resistance, which can be integrated with fungicide applications to achieve sustainable management of light leaf spot. Several major resistance genes and quantitative trait loci have been identified in previous studies, but rapid improvements in the understanding of molecular mechanisms underpinning B. napus–P. brassicae interactions can be expected through exploitation of novel genetic and genomic information for brassicas and extracellular fungal pathogens.

Abstract:
Clubroot, caused by Plasmodiophora brassicae, is an economically important soil-borne disease that threatens Brassicaceae crops worldwide. In recent years, the incidence area of Chinese cabbage (Brassica rapa ssp. pekinensis) clubroot disease has increased, which severely affects the yield and quality of Chinese cabbage. The resistance of varieties harboring the single clubroot-resistance (CR) gene is easily broken through by P. brassicae pathotypes. CRa and CRd, genetically identified in B. rapa, are CR genes known to be highly resistant to different P. brassicaea pathotypes. In our study, we perform the gene pyramiding of CRa and CRd in Chinese cabbages through marker-assisted selection (MAS), and develop homozygous pyramided lines. The newly generated pyramided lines exhibit greater resistance to six different pathotypes than that of two parental lines carrying a single CR gene. This study provides new CR-gene-pyramided lines for the development of clubroot-resistant Brassica varieties for future breeding programs.

Abstract:
Plasmodiophora brassicae Woronin, an obligate biotrophic soil-borne pathogen, poses a significant threat to cruciferous crops worldwide by causing the devastating disease known as clubroot. Pathogenic variability in P. brassicae populations has been recognized since the 1930s based on its interactions with Brassica species. Over time, numerous sets of differential hosts have been developed and used worldwide to explore the pathogenic variability within P. brassicae populations. These sets encompass a range of systems, including the Williams system, the European Clubroot Differential set (ECD), the Brassica napus set, the Japanese Clubroot Differential Set, the Canadian Clubroot Differential Set (CCS), the Korean Clubroot Differential Set, and the Chinese Sinitic Clubroot Differential set (SCD). However, all existing systems possess both advantages as well as limitations regarding the detection of pathotypes from various Brassica species and their corresponding virulence pattern on Brassica genotypes. This comprehensive review aims to compare the main differential systems utilized in classifying P. brassicae pathotypes worldwide. Their strengths, limitations, and implications are evaluated, thereby enhancing our understanding of pathogenic variability.

Abstract:
ABSTRACT: Alternaria brassicae causes a highly destructive disease in Brassica juncea (Rapeseed mustard) resulting in significant yield losses. Studies of MAPK machinery components in Arabidopsis thaliana have indicated that MPK3, MPK4, & MPK6 are involved in defense response and provide resistance against various bacterial and fungal pathogens. In this study, we analyzed the expression level of MPK3, MPK4 & MPK6 in overexpressed MPK3 transgenic (BjV5) Brassica juncea at different stages of Alternaria brassicae inoculation.Expression study revealed that MPK3/MPK6 was involved in early defense response and MPK4 in late defense response. These results suggested that BjMPK3 positively regulate SA mediated defense response, which might play an important role in resistance to Alternaria brassicae in Brassica juncea.

Abstract:
Asparagus Decline Syndrome is caused by Fusarium oxysporum f.sp. asparagi (FOA) and Fusarium moniliforme (FM). Resistant asparagus varieties have not been found and chemicals are often ineffective against Fusarium spp. Cabbage (Brassica oleracea) residue has been shown to reduce Fusarium infection in cabbage. However, canola (Brassica napus) also reduces yields in wheat.Seven Brassicas were selected for testing in the greenhouse and field (Kale, Turnip, Glacier Canola, Global Canola, Yellow Mustard, Dwarf Essex Canola, Humus Canola). Brassica residue added to soil reduced root growth of asparagus, wheat, cress, cucumber, and cabbage seedlings upto 4 weeks. Brassicas grown in the field reduced FOA populations and the incidence of Fusarium infection, but did not inhibit plant growth. Extraction of Brassica residue did not yield any non-volatile Fusarium-inhibitory compounds.

Abstract:
Samples of Brassica oleracea seed from Victoria, were tested for the presence of seed-borne Alternaria brassicicola and Alternaria brassicae. A. brassicicola was detected in 26 of 44 samples tested but A. brassicae was not detected in any. Between 24 and 37% of seed was infected, with 4-8% of infection found in the embryo tissues. Inoculation of seed with A. brassicicola resulted in loss of vigour in germinated seedlings, followed by death. The fungus retained its viability and pathogenicity on seed stored for up to 12 months. This investigation indicates that a high proportion of commercially available brassica seed are contaminated with A. brassicicola and may therefore be a primary source of disease for brassica crops in Australia.

Full text
Abstract:
Turnip mosaic virus (TuMV, family Potyviridae, genus Potyvirus) has the widest host range amongst potyviruses. Globally it was said to be the second most important virus infecting field vegetables. Brassica juncea (Oriental mustard, family Brassicaceae), is an amphidiploid plant species with the genome AABB, comprising the genomes of the two diploid species, Brassica rapa (AA) and Brassica nigra (BB). It is widely grown and has various uses including as a leaf, stem, or root vegetable, oilseed crop, forage crop, condiment and biofumigant. Most B. juncea cultivars are very susceptible to TuMV, resulting in severe losses. Research on TuMV resistance and the mapping and identification of natural resistance genes would be very useful in order to speed up breeding resistant crops through marker-assisted selection. Sources of resistance to TuMV have been identified in B. juncea. The specificity of the resistances has been determined. A B. juncea DH line for which there is genomic information has been challenged with TuMV and found to be susceptible. This line has been used as a susceptible parent in crosses with resistant plants derived from different sources to develop segregating populations for mapping the resistance gene(s). Two BC1 populations (222 plants and 205 plants) and one F2 population (159 plants) have been phenotyped and segregation ratios were not significantly different from a Mendelian model based on the action of two recessive genes. Parental lines and selected plants in the two BC1 populations have been analysed by SNPs genotyping using the Illumina Infinium Chip. Genetic linkage maps have been constructed and QTLs have been mapped. Additionally, attempts are being made to identify a dominant TuMV resistance gene present in both Brassica napus and B. rapa. Inter-specific crosses have been made in order to introgress this gene into B. juncea. Resynthesised B. juncea plants possessing this dominant resistance have been produced through embryo rescue and polyploidy induction of F1 plants from crosses between resistant B. rapa and susceptible B. nigra plants. BC2 plants have also been developed by crossing B. rapa and B. napus plants possessing the dominant TuMV resistance with a susceptible B. juncea plant line.

Full text
Abstract:
This project aimed to provide a greater understanding about resistance to Pyrenopeziza brassicae in oilseed rape. A doubled haploid population of Brassica napus derived from a cross between the resistant oilseed rape cultivar Imola and a susceptible breeding line was used to map a single major locus associated with resistance to P. brassicae. The locus was positioned at the end of the linkage group corresponding to chromosome A1, a region homeologous to Arabidopsis thaliana chromosome 3. The resistance was associated with a phenotype that involved reduced P. brassicae subcuticular hyphal growth, the collapse of epidermal cells and an absence of asexual sporulation. P. brassicae was, however, able to sporulate sexually on senescent leaf tissue of the resistant plants. For the doubled haploid population, there were significant correlations between severity of light leaf spot assessed on field plots in Hertfordshire and Scotland and severity assessed on seedlings in controlled environment conditions. Analysis using quantitative peR showed that the lines of the doubled haploid population differed in their ability to support the growth of P. brassicae in controlled environment (on cotyledons and young leaves) and field conditions. The resistance present in oil seed rape cultivar Imola is different from that observed in other B. napus cultivars/lines, where asexual sporulation was observed on even the least susceptible cultivars/lines, and currently appears stable in different parts of the UK. An improved understanding of resistance to P. brassicae in B. napus will help to inform decisions about the deployment of new resistant cultivars to maximise the durability of the resistance.

Abstract:
Nutrient-poor, sandy, sterile material from the post-mining sterile dumps such as those in the Maramures region (Romania) presents a challenge for plants. Sterile dumps are considered extreme environments for plants due to their unfavorable physicochemical properties. Phytoremediation has great potential to remove heavy metals from sterile dumps, and Indian mustard (Brassica juncea) seems to be a possible candidate species for this purpose. The potential of Brassica juncea seeds to germinate in a medium contaminated with high concentrations of Cu, Pb and Cd was assessed using germination tests on Indian mustard seeds in the presence of various liquid mixtures made from fertilizer and sterile material collected from three different mining sterile dumps in Maramures county, Romania. The experiment results showed that adding fertilizers did not enhance the germination process of Brassica juncea seeds and that the optimal pH for Brassica juncea to sprout extremely well is 5.5. The results suggest that Brassica juncea could be used in efficient phytoremediation of the sterile dumps. This paper's objective consists of observing the germination of Indian mustard (Brassica juncea L.) in the presence of high concentrations of heavy metals from sterile mining dumps with the purpose of the phytoremediation of the studied polluted areas from Maramures county (Romania).

Brassica nígra is an insufficiently studied crop under the conditions of the Crimean steppe zone. Therefore, the aim of the research was to study the biological characteristics, seed productivity, and yield quality indicators of some varieties of Brassica nígra in the aforementioned environmental conditions. We studied two varieties of Brassica nígra namely ‘Niagara’ and ‘Smuglyanka’ under rain-fed conditions without any fertilizers. Preceding crop – winter wheat. Cultivation technology – generally accepted. The growing season of ‘Niagara’ variety was 4-7 days shorter than that of ‘Smuglyanka’. This difference was due to the late emergence of seedlings. However, all the following stages of growth and development took place almost simultaneously. In 2017-2019, ‘Niagara’ variety gave the highest yield (0.45 t/ha) exceeding ‘Smuglyanka’ by 0.15 t/ha. The maximum content of fatty oil was in the ‘Niagara’ seeds – 39.3%; ‘Smuglyanka’ contained 24.7%. The main advantage of ‘Niagara’ – high content of essential oil in the seeds (0.96%), which is 3.7 times higher than in the seeds of the ‘Smuglyanka’ variety.

Abstract:
The whitefly (Bemisia tabaci) is a serious agricultural pest that afflicts a wide variety of ornamental and vegetable crop species. To enable survival on a great diversity of host plants, whiteflies must have the ability to avoid or detoxify numerous different plant defensive chemicals. Such toxins include a group of insect-deterrent molecules called glucosinolates (GSs), which also provide the pungent taste of Brassica vegetables such as radish and cabbage. In our BARD grant, we used the whitefly B. tabaci and Arabidopsis (a Brassica plant model) defense mutants and transgenic lines, to gain comprehensive understanding both on plant defense pathways against whiteflies and whitefly defense strategies against plants. Our major focus was on GSs. We produced transgenic Arabidopsis plants accumulating high levels of GSs. At the first step, we examined how exposure to high levels of GSs affects decision making and performance of whiteflies when provided plants with normal levels or high levels of GSs. Our major conclusions can be divided into three: (I) exposure to plants accumulating high levels of GSs, negatively affected the performance of both whitefly adult females and immature; (II) whitefly adult females are likely to be capable of sensing different levels of GSs in their host plants and are able to choose, for oviposition, the host plant on which their offspring survive and develop better (preference-performance relationship); (III) the dual presence of plants with normal levels and high levels of GSs, confused whitefly adult females, and led to difficulties in making a choice between the different host plants. These findings have an applicative perspective. Whiteflies are known as a serious pest of Brassica cropping systems. If the differences found here on adjacent small plants translate to field situations, intercropping with closely-related Brassica cultivars could negatively influence whitefly population build-up. At the second step, we characterized the defensive mechanisms whiteflies use to detoxify GSs and other plant toxins. We identified five detoxification genes, which can be considered as putative "key" general induced detoxifiers because their expression-levels responded to several unrelated plant toxic compounds. This knowledge is currently used (using new funding) to develop a new technology that will allow the production of pestresistant crops capable of protecting themselves from whiteflies by silencing insect detoxification genes without which successful host utilization can not occur. Finally, we made an effort to identify defense genes that deter whitefly performance, by infesting with whiteflies, wild-type and defense mutated Arabidopsis plants. The infested plants were used to construct deep-sequencing expression libraries. The 30- 50 million sequence reads per library, provide an unbiased and quantitative assessment of gene expression and contain sequences from both Arabidopsis and whiteflies. Therefore, the libraries give us sequence data that can be mined for both the plant and insect gene expression responses. An intensive analysis of these datasets is underway. We also conducted electrical penetration graph (EPG) recordings of whiteflies feeding on Arabidopsis wild-type and defense mutant plants in order to determine the time-point and feeding behavior in which plant-defense genes are expressed. We are in the process of analyzing the recordings and calculating 125 feeding behavior parameters for each whitefly. From the analyses conducted so far we conclude that the Arabidopsis defense mutants do not affect adult feeding behavior in the same manner that they affect immatures development. Analysis of the immatures feeding behavior is not yet completed, but if it shows the same disconnect between feeding behavior data and developmental rate data, we would conclude that the differences in the defense mutants are due to a qualitative effect based on the chemical constituency of the phloem sap.

Abstract:
There is documented evidence of the adulteration of saw palmetto fruit extracts with a number of vegetable oils, such as canola (Brassica napus ssp. napus, Brassicaceae), coconut (Cocos nucifera, Arecaceae), olive (Olea europaea, Oleaceae), palm (Elaeis guineensis, Arecaceae), peanut (Arachis hypogaea, Fabaceae), and sunflower (Helianthus annuus, Asteraceae) oils. The partial or complete substitution of saw palmetto fruit extracts with mixtures of fatty acids of animal origin was first documented in 2018, and seems particularly common in materials sold as saw palmetto originating from China. This Laboratory Guidance Document (LGD) presents a review of the various analytical technologies used to differentiate between authentic saw palmetto extracts and ingredients containing adulterating materials. This document can be used in conjunction with the Saw Palmetto Botanical Adulterants Bulletin, rev. 3, published by the ABC-AHP-NCNPR Botanical Adulterants Prevention Program in 2018.
