Project description:Light exposure quickly inhibits the elongation of mesocotyl of rice seedling. The two corresponding periods from darkness to loght (D_5d, L_1h) were selected to perform degradome sequencing.

Project description:We investigated the role of ppGpp in Synechococcus elongatus PCC7942 in light/dark conditions. We performed RNA-seq experiments using wild type and the rel- strain at dusk and during exposure to 12 h of darkness. We show that ppGpp is required for correct response to darkness.
Project description:rs09-09_della-dark - della-regulation in darkness versus light - Identification of DELLA-dependent downstream targets in darkness - Aim was to determine downstream target of DELLA proteins involved in skotomorphogenesis. Wt, ga1-3, ga1-3_rga_gai_rgl1_rgl2_rgl3 global seeds were sterilized, sown on MS agar plates then put for stratification for 3 days at 4°C. Plates were placed in growth cabinet at 22°C for 5 days in darkness or in continous light. Keywords: gene knock out
Project description:The mesocotyl, a structure separating the grass seedling cotyledon from the coleoptile, exerts a major influence over the seedling’s ability to emerge. Its elongation is inhibited by light. A transcriptomic comparison between mesocotyl tissue which had developed in the dark and which had been exposed to light identified a large number of differentially transcribed genes (DTGs)
Project description:au10-03_hub1 - kinetics of gene expression after light exposure in hub1-3 mutant compared to wild-type - Role of histone UbH2B in the regulation of gene expression in response to light - RNA from 5-day-old wild-type and hub1-3plants in 3 conditions were used for hybridization: 5 days of darkness, 5 days of darkness + 1 hour of light and 5 days of darkness + 6 hours of light. Keywords: genotype comparaison,time course

Project description:We investigated the role of ppGpp in Synechococcus elongatus PCC7942 in light/dark conditions. We performed ChIP-seq experiments using wild type and the rel- strain at dusk, during exposure to 12 h of darkness and at dawn. We show that the RNA polymerase pausing index is globally lower in the rel- strain.
