Project description:To understand how GA functions in regulating embryo development, a genome-wide transcriptomic analysis was carried out using 9DAF seeds dissected from siliques of dellaq (rga28 gai rgl1 rgl2) and the wild-type (col-0-2) grown in full-spectrum white fluorescent light at 22°C under long day conditions (16 h light/8 h dark). Then we found that GA regulates embryo development via DELLA-LEC1interaction, a subsequent genome-wide transcriptomic analysis was carried out using 9DAF seeds dissected from siliques of lec1-4 and the wild-type (col-0-1) in the same growth condition. Basing on the criteria of 1.5-fold cutoff for the genes with 5% false discovery rate, we first identified the differentially expressed genes in dellaq vs col-0-2, lec1-4 vs Col-0-1 subsets, which are referred to as DELLA and LEC1 regulated genes. These data reveal that DELLAs and LEC1 co-target a set of common genes in late embryogenesis, strongly supporting the role of DELLA-LEC1 in embryo development.
Project description:The total mRNA and polysomal RNA expression profiles of wild type (Col-0) and the quadruple spa mutant (spaQ) were analyzed under dark or in 4 hour light treated condition. The gene expression changed in spaQ mutant was analyzed and compared with Col-0.
Project description:Transcriptional profiling of 60h-old Arabidopsis whole seedlings comparing control Col-0 wild-type plants with pifQ mutant plants The expression profile of dark-grown pifQ mutant shows similar pattern of Rc-grown Col-0 wild-type Keywords: Genetic modification
Project description:Transcriptional profiling of Arabidopsis far-red light pulse treated seeds comparing luh mutant with wild type (Col-0). Seeds were imbibed within 1 hr under white light and treated far-red light pulse for 5 min followed by 12 hr dark incubation. Goal was to determine the effects of LUH as transcriptional co-regulator during seed germination process.
