Full textAbstract:
The small YABBY plant-specific transcription factor has a prominent role in regulating plant growth and developmental activities. However, little information is available about YABBY gene family in Triticum aestivum L. Herein, we identified 21 TaYABBY genes in the Wheat genome database. Then, we performed the conserved motif and domain analysis of TaYABBY proteins. The phylogeny of the TaYABBY was further sub-divided into 6 subfamilies (YABBY1/YABBY3, YABB2, YABBY5, CRC and INO) based on the structural similarities and functional diversities. The GO (Gene ontology) analysis of TaYABBY proteins showed that they are involved in numerous developmental processes and showed response against environmental stresses. The analysis of all identified genes in RNA-seq data showed that they are expressed in different tissues of wheat. Differential expression patterns were observed in not only control samples but also in stressed samples such as biotic stress (i.e., Fusarium graminearum (F.g), septoria tritici (STB), Stripe rust (Sr) and Powdery mildew (Pm), and abiotic stress (i.e., drought, heat, combined drought and heat and phosphorus deficiency), especially at different grain development stages. All identified TaYABBY-genes were localized in the nucleus which implies their participation in the regulatory mechanisms of various biological and cellular processes. In light of the above-mentioned outcomes, it has been deduced that TaYABBY-genes in the wheat genome play an important role in mediating various development, growth, and resistance mechanism, which could provide significant clues for future functional studies.

Evolution of the genes encoding YABBY transcription factors is believed to be one of the key reasons for flat leaf emergence from the radially symmetrical stem and gynoecium diversity. YABBY genes determine the identity of the abaxial surface of all aboveground lateral organs in seed plants. In the present study, complete sequences of YABBY3-orthologous genes were identified and characterized in 13 accessions of cultivated and wild tomato species with diverse morphophysiology of leaves, flowers, and fruits. The obtained gene sequences showed high homology (95-99%) and an identical exon-intron structure with the known S. lycopersicum YABBY3 gene, and they contained sequences that encode the conserved HMG-like YABBY and Cys2Cys2-zinc-finger domains. In total, in the analyzed YABBY3 genes, 317 variable sites were found, wherein 8 of 24 exon-specific SNPs were nonsynonymous. In the vegetative and reproductive organs of red-fruited and green-fruited tomato species, YABBY3 gene expression was similar to that in S. pimpinellifolium described earlier, but it demonstrated interspecies differences at the leaf-, bud- and flower-specific expression levels.

Full textAbstract:
Lateral organs produced by shoot apical and flower meristems exhibit a fundamental abaxial-adaxial asymmetry. We describe three members of the YABBY gene family, FILAMENTOUS FLOWER, YABBY2 and YABBY3, isolated on the basis of homology to CRABS CLAW. Each of these genes is expressed in a polar manner in all lateral organ primordia produced from the apical and flower meristems. The expression of these genes is precisely correlated with abaxial cell fate in mutants in which abaxial cell fates are found ectopically, reduced or eliminated. Ectopic expression of either FILAMENTOUS FLOWER or YABBY3 is sufficient to specify the development of ectopic abaxial tissues in lateral organs. Conversely, loss of polar expression of these two genes results in a loss of polar differentiation of tissues in lateral organs. Taken together, these observations indicate that members of this gene family are responsible for the specification of abaxial cell fate in lateral organs of Arabidopsis. Furthermore, ectopic expression studies suggest that ubiquitous abaxial cell fate and maintenance of a functional apical meristem are incompatible.

Full textAbstract:
The YABBY gene family, specific to seed plants, encodes a class of transcription factors in the lamina maintenance and development of lateral organs. Magnoliids are sisters to the clade-containing eudicots and monocots, which have rapidly diversified among the common ancestors of these three lineages. However, prior to this study, information on the function of the YABBY genes in magnoliids was extremely limited to the third major clades and the early diverging lineage of Mesangiospermae. In this study, the sum of 55 YABBY genes including five genes in INO, six in CRC, eight in YAB2, 22 in YAB5, and 14 in FIL clade were identified from seven magnoliid plants. Sequence analysis showed that all encoded YABBY protein sequences possess the highly conserved YABBY domain and C2C2 zinc-finger domain. Gene and protein structure analysis indicates that a certain number of exons were highly conserved and similar in the same class, and YABBY genes encode proteins of 71–392 amino acids and an open reading frame of 216–1179 bp in magnoliids. Additionally, the predicted molecular weight and isoelectric point of YABBY proteins in three species ranged from 7689.93 to 43578.13 and from 5.33 to 9.87, respectively. Meanwhile, the YABBY gene homolog expression of Litsea was detected at a temporal and spatial level during various developmental stages of leaf and reproductive tissues. This research could provide a brief overview of YABBY gene family evolution and its differential expression in magnoliids. Therefore, this comprehensive diversification analysis would provide a new insight into further understanding of the function of genes in seven magnoliids.

Full textAbstract:
Mounting evidence from genomic and transcriptomic studies suggests that most genetic networks regulating the morphogenesis of land plant sporophytes were co-opted and modified from those already present in streptophyte algae and gametophytes of bryophytes sensu lato. However, thus far, no candidate genes have been identified that could be responsible for “planation”, a conversion from a three-dimensional to a two-dimensional growth pattern. According to the telome theory, “planation” was required for the genesis of the leaf blade in the course of leaf evolution. The key transcription factors responsible for leaf blade development in angiosperms are YABBY proteins, which until recently were thought to be unique for seed plants. Yet, identification of a YABBY homologue in a green alga and the recent findings of YABBY homologues in lycophytes and hornworts suggest that YABBY proteins were already present in the last common ancestor of land plants. Thus, these transcriptional factors could have been involved in “planation”, which fosters our understanding of the origin of leaves. Here, we summarise the current data on functions of YABBY proteins in the vegetative and reproductive development of diverse angiosperms and gymnosperms as well as in the development of lycophytes. Furthermore, we discuss a putative role of YABBY proteins in the genesis of multicellular shoot apical meristems and in the evolution of leaves in early divergent terrestrial plants.

Full textAbstract:
The plant YABBY transcription factors are key regulators in the lamina development of lateral organs. Orchid is one of the largest families in angiosperm and known for their unique floral morphology, reproductive biology, and diversified lifestyles. However, nothing is known about the role of YABBY genes in orchids, although biologists have never lost their fascination with orchids. In this study, a total of 54 YABBY genes, including 15 genes in CRC/DL, eight in INO, 17 in YAB2, and 14 in FIL clade, were identified from the eight orchid species. A sequence analysis showed that all protein sequences encoded by these YABBY genes share the highly conserved C2C2 zinc-finger domain and YABBY domain (a helix-loop-helix motif). A gene structure analysis showed that the number of exons is highly conserved in the same clades. The genes in YAB2 clade have six exons, and genes in CRC/DL, INO, and FIL have six or seven exons. A phylogenetic analysis showed all 54 orchid YABBY genes could be classified into four major clades, including CRC/DL, INO, FIL, and YAB2. Many of orchid species maintain more than one member in CRC/DL, FIL, and YAB2 clades, implying functional differentiation among these genes, which is supported by sequence diversification and differential expression. An expression analysis of PhalaenopsisYABBY genes revealed that members in the CRC/DL clade have concentrated expressions in the early floral development stage and gynostemium, the fused male and female reproductive organs. The expression of PeINO is consistent with the biological role it played in ovule integument morphogenesis. Transcripts of members in the FIL clade could be obviously detected at the early developmental stage of the flowers. The expression of three genes, PeYAB2,PeYAB3, and PeYAB4, in the YAB2 clade could be revealed both in vegetative and reproductive tissues, and PeYAB4 was transcribed at a relatively higher level than that of PeYAB2 and PeYAB3. Together, this comprehensive analysis provides the basic information for understanding the function of the YABBY gene in Orchidaceae.

Full textAbstract:
It is believed that the complete mycoheterotroph pinesap Monotropa hypopitys adaptively evolved from a photosynthetic mycorrhizal ancestor, which had lost its photosynthetic apparatus and vegetative organs (stem and leaves). The aerial part of the plant is a reproductive axis with sterile bracts and inflorescence with a flower type canonical for higher plants. The origin of leaves and leaf-like lateral organs is associated, among other factors, with the evolution of the YABBY genes, which are divided into“vegetative” and evolutionarily recent“reproductive” genes, with regard to their expression profiles. The study of the vegetative YABBY genes in pinesap will determine whether their functions (identification of cell identity on the abaxial surface of the lateral organs) are preserved in the leafless plant. In this study, the structural and phylogenetic analysis of the pinesap vegetative genes MhyFIL1 and MhyFIL3 is performed, the main conserved domains and motifs of the encoded proteins are characterized, and it is confirmed that the genes belong to the vegetative clade YABBY3/FIL. The effect of heterologous ectopic expression of the MhyFIL1 and MhyFIL3 genes on the phenotype of transgenic tobacco Nicotiana tabacum is evaluated. The leaves formed by both types of plants, 35S::MhyFIL1 and 35S::MhyFIL3, were narrower than in control plants and were twisted due to the changed identity of adaxial surface cells. Also, changes in the architecture of the aerial part and the root system of transgenic plants, including aberrant phyllotaxis and arrest of the shoot and root apical meristem development, were noted. Some of the 35S::MhyFIL1 and 35S::MhyFIL3 plants died as early as the stage of the formation of the first leaves, others did not bloom, and still others had a greatly prolonged vegetation period and formed fewer flowers than normal ones. The flowers had no visible differences from the control except for fragile pedicles. Thus, the absence of structural changes from the M. hypopitys flower in comparison to autotrophic species and the effect of MhyFIL1/3 heterologous expression on the development of tobacco plants indicate the preservation of the functions of the vegetative YABBY genes by the MhyFIL1/3 genes in pinesap. Moreover, the activity of YABBY transcription factors of the FIL clade in M. hypopitys is not directly related to the loss of the ability of pinesap to form leaves during the evolutionary transition from autotrophic nutrition to heterotrophy.

Full textAbstract:
The YABBY family of plant-specific transcription factors play important regulatory roles during the development of leaves and floral organs, but their functions in Brassica species are incompletely understood. Here, we identified 79 YABBY genes from Arabidopsis thaliana and five Brassica species (B. rapa, B. nigra, B. oleracea, B. juncea, and B. napus). A phylogenetic analysis of YABBY proteins separated them into five clusters (YAB1–YAB5) with representatives from all five Brassica species, suggesting a high degree of conservation and similar functions within each subfamily. We determined the gene structure, chromosomal location, and expression patterns of the 21 BnaYAB genes identified, revealing extensive duplication events and gene loss following polyploidization. Changes in exon–intron structure during evolution may have driven differentiation in expression patterns and functions, combined with purifying selection, as evidenced by Ka/Ks values below 1. Based on transcriptome sequencing data, we selected nine genes with high expression at the flowering stage. qRT-PCR analysis further indicated that most BnaYAB family members are tissue-specific and exhibit different expression patterns in various tissues and organs of B. napus. This preliminary study of the characteristics of the YABBY gene family in the Brassica napus genome provides theoretical support and reference for the later functional identification of the family genes.

Full textAbstract:
Background The YABBY gene family is a family of small zinc finger transcription factors associated with plant morphogenesis, growth, and development. In particular, it is closely related to the development of polarity in the lateral organs of plants. Despite being studied extensively in many plant species, there is little information on genome-wide characterization of this gene family in Moso bamboo. Methods In the present study, we identified 16 PeYABBY genes, which were unequally distributed on 11 chromosomes, through genome-wide analysis of high-quality genome sequences of M oso bamboo by bioinformatics tools and biotechnological tools. Gene expression under hormone stress conditions was verified by quantitative real-time PCR (qRT-PCR) experiments. Results Based on peptide sequences and similarity of exon-intron structures, we classified the PeYABBY genes into four subfamilies. Analysis of putative cis-acting elements in promoters of these genes revealed that PeYABBYs contained a large number of hormone-responsive and stress-responsive elements. Expression analysis showed that they were expressed at a high level in Moso bamboo panicles, rhizomes, and leaves. Expression patterns of putative PeYABBY genes in different organs and hormone-treated were analyzed using RNA-seq data, results showed that some PeYABBY genes were responsive to gibberellin (GA) and abscisic acid (ABA), indicating that they may play an important role in plant hormone responses. Gene Ontology (GO) analyses of YABBY proteins indicated that they may be involved in many developmental processes, particularly high level of enrichment seen in plant leaf development. In summary, our results provide a comprehensive genome-wide study of the YABBY gene family in bamboos, which could be useful for further detailed studies of the function and evolution of the YABBY genes, and to provide a fundamental basis for the study of YABBY in Gramineae for resistance to stress and hormonal stress.

A study under controlled conditions of ovarian development and rematuration in the yabby (Cherax destructot) was undertaken. The purpose of the study was to improve fundamental understanding of the reproductive biology of the species and provide a basis for application to hatchery management in culture.
A review was made of the current status of yabby culture in Australia and the present understanding of reproductive biology of decapod Crustacea. The review emphasised factors controlling several aspects of ovarian development, in particular the processes of vitellogenesis. The subsequent study was designed within the context of current hatchery practice and was based on existing knowledge of decapod reproduction,
The sexual differentiation of the yabby after hatching was investigated by serial histological sections, and experiments were carried out to investigate the possibility of sex reversal of males. Most of this Investigation was concerned with removing the influence of the androgenic gland in directing male development, with the intent of observing the development of the elementary gonadal tissue into ovary. It was found that in contrast to other crustacean species, the sex of the yabby becomes fixed before the development of external secondary sexual characteristics, and before the androgenic gland can be discerned. Ovarian tissue developed in females at less than 8 weeks after hatching. A preliminary examination was undertaken for feminising parasites in gonadal tissue of a hermaphrodite yabby.
Investigation of the ovary after spawning demonstrated that whilst the female was held under constant conditions of temperature and photoperiod, little rematuration occurred. Except for generation of previtellogenic oocytes during the first two days, the gonaciosomatic index remained low for up to 5 months after spawning. If the temperature of the female was reduced to 10°C and maintained constant, the previtellogenic oocytes were partially resorbed over a three week period. Rematuration then commenced, albeit at a low rate because of the reduced temperature,
A method for standardising gonadosomatic indices was developed which took into account differences in hepatopancreatic nutrient reserves of individuals and loss of one
or more appendages. This part of the study also considered constraints to rematuration and developed a method of accounting for differences in the ability of females to remature after spawning.
Experiments were carried out to investigate the effect of crowding and temperature manipulation on initiating ovarian rematuration and to determine the rate of rematuration at 22°C once initiated. The duration of low temperature had no effect on rematuration; an overnight cooling was sufficient to initiate the process, Rematuration to the end of stage 2 vltellogenesis was substantially complete within 10 days. Crowding of females suppressed rematuration, but less than ideal water quality was not found to have any effect. The presence of a male initiated rematuration at a similar rate, but also led to stage 3 vitetlogenesis and spawning. A study was made of the pheromonal influence of the male through water borne factors without success. Rematuration could not be induced in ovigerous females.
The literature review indicated that ovarian rematuration was under the control of an ovary stimulating hormone produced by the thoracic nerve ganglia. Attempts were therefore made to stimulate ovarian rematuration by incorporating the thoracic nerve into the diet of females. Attempts were also made to induce the release of ovary stimulating hormone from the thoracic nerve with 5-hydroxytryptamine, and also with octopamine. No effects were found, but a significant difference between the neurophysiology of the yabby and northern hemisphere crayfish was observed, and the implications of this finding are discussed. The study did not produce any conclusive evidence of an ovary stimulating hormone for the yabby.
A model of ovarian rematuration which collects the findings of the experimental investigations was developed, and was used to suggest a hatchery broodstock management protocol. This model differs from existing models in that rematuration triggers and nutritional status are considered.

Full textAbstract:
Brachypodium, as a sister to the core pooids containing wheat, barley, oats and rye, represents a good model and point of comparison for the study of development and evolution in temperate cereals. Using a comparative cellular developmental and transcriptomic approach, we investigated regulation of key stages in grain development. This was achieved by generating a transcriptome incorporating several distinct developmental stages of Brachypodium grains; pre-anthesis ovaries, young grain (1-3 DAA), mid-length grain (3-8 DAA), full-length (8-15 DAA) and mature grain (15-24 DAA), mature grain (without embryo), germinating grains and seedlings stage. By looking at the differential expression of genes through grain development we identified clusters that coincide with the initiation of key developmental stages, such as the initiation of endosperm proliferation, cellularisation and differentiation, as well as the activation of specific metabolic pathways, such as starch and protein biosynthesis. Focus was given to members of the YABBY gene family that have an established role in promoting abaxial cell fate and as master regulators of reproductive development in eudicots, but with less clarity in grass species. Using Brachypodium as the model plant for cereal crops, the orthologues of YABBY genes in grasses were identified and subjected to detailed phylogenetic, expression and functional analyses using Bayesian Interference (BI) analyses, RT-PCR, transcriptomics, mRNA in situ hybridization (ISH) and RNAi. Based on several analyses, YABBY6 was suggested as a novel candidate of transcription factors regulating seed development in Brachypodium. Metadata from Chapter 2 were used to extract similar expression genes of YABBY family members and potential motifs regulated in polarity networks involving YABBY genes were suggested.

Full textAbstract:
L'apparition de la fleur a nécessité trois événements majeurs: (i) le regroupement des organes reproducteurs mâles et femelles sur un même axe, (ii) l'internalisation des ovules au sein d'un organe: le carpelle, (iii) la mise en place de pièces stériles en périphérie des organes reproducteurs. Ce travail de thèse consiste en l'identification d'événements moléculaires à l'origine du carpelle. Les gènes ARF3 et ARF4 jouent un rôle clé dans le développement du carpelle chez l'espèce modèle Arabidopsis thaliana. La reconstruction de l'histoire évolutive de ces gènes a permis de montrer qu'ils résultaient d'une duplication dans le lignage menant aux angiospermes. Leurs structures indiquent qu'ils ont évolué par perte de certains domaines protéiques, ceci de manière indépendante dans les lignages ARF3 ou ARF4. Ces changements dans la partie codante constituent un mode d'évolution généralisable à l'ensemble des embryophytes. La famille génique YABBY intervient dans l'établissement de la polarité adadiale-abaxiale des organes latéraux. En particulier, les gènes CRC et INO constituent respectivement deux marqueurs moléculaires du carpelle et de l'ovule. L'étude préliminaire de cette famille semble indiquer l'absence du gène CRC chez les gymnospermes, suggérant que l'apparition de CRC aurait été un pré-requis pour l'origine évolutive du carpelle.

Most plant organs are formed post-embryonically in a continuous manner through the activity of highly organised and dynamic structures called meristems. SHOOT MERISTEMLESS (STM), a member of the KNOX gene family, is a key regulatory gene that maintains shoot meristem cells undifferentiated . Based on a transcriptional profiling approach, YABBY3 (YAB3), which is a central regulator of organ polarity, emerged as one of the potential candidates for direct regulation by STM.

Full textAbstract:
A study of the older readers' section of Young Australians Best Book Award (YABBA) from 1986 to 1991, based on analysis of 21,351 voting forms from this period. Through analysis of the data from these voting forms, ranking authors and titles, comparing gender preferences, the source of the book voted for, school type and school location were all compiled into graphs and tables. Appropriate comparisons have been made between variables across the six year period, to give some idea of the voting population involved in the older readers' section of YABBA and their preferences and motivations. A follow up survey of voters and YABBA organisers in 1992 attempted to further enhance this data by collecting information on voter preferences, opinions and possible influences on the voting process. The study attempts to place YABBA in the context of the wider children's literature community and discuss briefly its historical development with reference to other children's choice awards, their strengths and weaknesses. A relevant discussion on popularity versus literary merit is related to the ongoing discussion of YABBA in comparison to the Children's Book Council awards. Later chapters include a discussion of the most popular YABBA titles (seven highest rating titles) with particular emphasis given to YABBA's two most popular authors - Paul Jennings and Robin Klein. Humour is an important factor in the popularity of many YABBA titles and this is discussed as are developments since 1991 and the long-term future of YABBA.

This edition includes a chapter on water quality plus the latest findings in yabby farming. It provides a grounding in the basic principles of aquaculture and reflects the considerable advances in aquaculture technology over the last few years.
Here is the basic information on the yabby, its habitat, its health and nutrition requirements. The book covers pond management, production systems, equipment, harvesting, post-harvest handling, and marketing of the end product. It includes sections on the farming of those other freshwater crayfish, the redclaw and the marron, and contains a number of useful appendices.
Author John Mosig shares his experience of nearly 20 years, giving budding yabby farmers an insight into how they can run a yabby venture while developing their own aquaculture skills and gaining experience in fish husbandry. Practising crayfish farmers might find out how they too can do some things better.

Full textAbstract:
Crayfish have been in demand as desirable food items around the globe for centuries, and entrepreneurs have capitalized on this demand by developing and applying aquaculture principals for the intentional culture of this freshwater crustacean. The current state of the art has advanced within the last half century and is centered on a handful of species, represented by three different families, with some level of commercial production occurring on all continents except Antarctica. Procambarus clarkii (family Cambaridae), a native of south central USA, is cultured in the USA and China and easily forms the bulk of farm-raised and wild-captured crayfish globally. One North American species (Pacifastacus leniusculus) and two European species (Astacus astacus and A. leptodactylus) constitute the main cultured species from the family Astacidae and are grown in small operations throughout Europe and parts of Asia. Four species (Parastacidae), all natives of Oceania, are cultured in their native ranges and were also introduced for aquaculture in several locations around the globe. Cherax destructor and C. albidus, both commonly referred to as yabby, are medium-size crayfish and share similar life histories, whereas C. quadricarinatus (redclaw crayfish) and C. cainii (smooth marron) are larger and more valuable but have very different geographical origins. While commercial crayfish aquaculture is typically based on an extensive or semi-extensive production approach in earthen ponds, more intensive approaches may involve selective breeding, improved strains, brood or nursery phases, and use of raceways or recirculation systems. Pond size can range from 0.05 to 80 ha, depending on the species cultured. Harvesting is accomplished mainly by baited trap, although other gear and techniques are sometimes employed. Global crayfish aquaculture production has expanded significantly in the last decade, due largely to the integration of Procambarus clarkii with that of rice production in the USA and China. This integrated system of production works well because rice farming has similar requirements as crayfish aquaculture, such as clay soils, irrigation systems, and suitable climates; furthermore, the rice crop residue provides the base of the food web for furnishing sustenance to growing crayfish.
