Project description:The expression levels of Arabidopsis thaliana (Col-0) genes in several developmental stages during the seed-to-seedling transition were measured by using high-density Affymetrix® arrays (Aragene.st1.1). We used a time-series of microarrays to gain temporal resolution and identify relevant genes in the seed-to-seedling transition.

Project description:During the embryonic-to-vegetative transition in plants, many genes that were active in seeds become transcriptionally turned off. Recently, we reported a new transcriptional corepressor of the embryonic program, SEED DORMANCY 4-LIKE (AtSDR4L). Multiple lines of evidence suggest that AtSDR4L plays an essential role in regulating the transition from seed to seedling, possibly by collaborating with components of Polycomb Repressive Complexes (PRCs) and PRC-associated proteins VIVIPAROUS1/ABI3-LIKE (VAL) proteins. Through yeast-two-hybrid (Y2H) assays and genome-wide binding analysis, we demonstrated that AtSDR4L and DIG1 physically interact with VAL2 but not with VAL1. The interactions depend on the C-terminal halves of AtSDR4L and DIG1, and the N-terminal half of VAL2. AtSDR4L binds to target loci in germinating seeds, preceding reduced accumulation of H3K27me3 Atsdr4l seedlings at a few loci important for seed development. These findings suggest AtSDR4L, and potentially DIG1, facilitate the recruitment of PRC2 through VAL2 to inactivate seed development genes, thus promoting the seed-to-seedling transition.

Project description:Common bean (Phaseolus vulgaris L.) is the most consumed grain legume in developing countries in Latin America and Sub-Saharan Africa1. Like other legumes, common bean seeds are rich in protein, carbohydrates, fibers and other health-promoting phenolic compounds thus being vital for food security and income source for local small farmers2. Seed quality traits depend on accumulation of various storage molecules during the seed development (SD) process and influenced by the genotype and adaptive changes to environment3. Concerning common bean, there is still a lack of a deeper molecular knowledge of SD that is hampering the development of new biotech approaches for seed trait modulation and could timely address challenges of agriculture or industry. Our present work aims to unravel the molecular mechanisms underlying SD using a proteomic approach. To achieve this goal, we characterized SD in terms biomass, seed length and weight in the genotype SER16, one of the most promissory drought-resistant release of the CIAT-CGIAR. Seed samples were collected at the 4 main SD stages: Late-Embryogenesis (10 days after anthesis, d.a.a.), Early (20 d.a.a.) and Late Maturation (30 d.a.a.) and Desiccation (40 d.a.a.). The analysis of bean proteome was conducted using a gel-free proteomic analysis (LC-MS/MS) under the scope of EU-FP7-PRIME-XS project. A total of 410 unique proteins were differentially expressed throughout the 4 major seed development stages, in which most of the identified proteins belong in the ‘protein metabolism’ (31,98%) functional category, that includes synthesis, regulation, folding. Other functional categories are represented such as carbohydrate and lipid metabolism (11,26%) and stress/defense and redox metabolism (11,04%). We identified 93 proteins were unique to the first (10-20 d.a.a.), 22 to the second (20-30 d.a.a.) and 40 to the last (30-40 d.a.a.) phase transition, reflecting the major biological processes occurring at this specific seed developmental stage. This study will contribute to reveal key metabolic pathways and mechanisms with potential role in modulating common bean seed development and quality traits.

Project description:What methylation changes are occurring during seed development largely remains unknown. To uncover the possible role of DNA methylation throughout all of seed development - from fertilization through dormancy and post-germination in soybean, we characterized the methylome of whole seeds representing the differentiation (GLOB and COT stages), maturation (early- [EM], mid- [B1] and late- [AA1] maturation stages), dormancy (DRY stage), and post-germination (seedling) phases of soybean seed development using Illumina sequencing. In addition, we characterized the methylome of the cotyledons of germinated seedling to examine methylation differences before and after germination.
