Project description:The nuclei of Glycine max from different tissues were collected. The samples were: soybean seed mid-maturation stage (10mm), seed late cotyledon stage (5mm), seed early cotyledon stage (3mm), seed heart stage (1mm), soybean green pods without seeds (stage), soybean flower bud (early flowering stage), soybean shoot apical meristem (stage), soybean trifoliate leaf (R5 stage), and soybean true leave (stage). The library construction was performed applying 10 Genomics technology.

Project description:In deciduous fruit trees, entrance into dormancy occurs in later summer/fall, concomitantly with the shortening of day length and decrease in temperature. Generally speaking, dormancy can be divided into endodormancy, ecodormancy and paradormancy. In Prunus species flower buds, entrance into the dormant stage occurs when the apical meristem is partially differentiated; during dormancy, flower verticils continue their growth and differentiation. In this work we focused our attention on flower bud development during winter in peach. In order to understand how bud development progress is regulated during winter we integrated cytological epigenetic and chromatin genome wide data with transcriptional outputs to obtained a complete picture of the main regulatory pathways involved in endodormancy.

Project description:The aim of this study was to evaluate gene expression defects at the shoot apical meristem and young flower meristems of the vip3-1 null allele. VIP3 belongs to polymerase II-associated factor 1 complex (Paf1c), which is involved in several RNA polymerase II-dependent transcriptional processes. Arabidopsis vip3 mutants exhibit phylotactic defects and strong floral indeterminacy phenotypes.

Project description:To investigate the cooperation of light drought with flower branches building and flower bud formation in Citrus, we set two groups including 75 days light drought (LD) and CK to uncover which target genes relatived to flower bud and branches building have been influenced by LD. We then performed gene expression profiling analysis using data obtained from RNA-seq of two different treatment.

Project description:Correlative controls (influences of one organ over another organ) of seeds over maternal growth are one of the most obvious phenotypic expressions of the trade-off between growth and reproduction. However, the underlying molecular mechanisms are largely unknown. Here, we characterize the physiological and molecular effects of correlative inhibition by seeds on Arabidopsis thaliana inflorescences, i.e. global proliferative arrest (GPA) during which all maternal growth ceases upon the production of a given number of seeds. We use laser-assisted microdissection and RNA-seq or Affymetrix GeneChip hybridizations to compare sterile growing, fertile growing and fertile arrested meristems or whole inflorescences. In shoot tissues, we detected the induction of stress- and senescence-related gene expression upon fruit production and GPA, and a drop in chlorophyll levels - suggestive of altered source-sink relationships between vegetative shoot and reproductive tissues. Levels of shoot reactive oxygen species, however, strongly decreased upon GPA - a phenomenon that is associated with bud dormancy in some perennials. Indeed, gene expression changes in arrested apical inflorescences after fruit removal resembled changes observed in axillary buds following release from apical dominance. This suggests that GPA represents a form of bud dormancy, and that dominance is gradually transferred from growing inflorescences to maturing seeds - allowing offspring control over maternal resources, simultaneously restricting offspring number.

Project description:Perennial plants alternate between periods of active growth and periods of dormancy. Prerequisite to bud dormancy is the formation of an apical bud. Short day photoperiod in the fall induces bud formation in poplar. Transgenic plants overexpressing the bZIP transcription factor FD do not stop growing and do not form a bud. In order to better understand the molecular events leading to bud formation, we used microarrays to compare the transcriptomes of shoot tips of poplars overexpressing FD and wild type plants (1) grown under long day conditions and (2) collected after 3 weeks under short day conditions
