Project description:The douple mutant Arabidopsis thaliana soc1 ful, in contrast with WT, produces an interfascicular cambium and a large wood cylinder is the flowering stem. We present the RNAseq data for polyA mRNA of different developmental stages of cambium and wood formation in Arabidopsis thaliana. We sequenced 7 stages; 4 in the woody mutant soc1-6 ful-7 (herbaceous, cambium initiation, wood initiation and leaf) and 3 stages in the WT Col-0 (herbaceous, cambium and leaf). The corresponding stem anatomy is also presented in the manuscript indicating the stage of cambium development and the production of secondary xylem.

Project description:Typically, when fully developed leaves of Arabidopsis thaliana are exposed to an increase in light intensity, they are able to increase their photosynthetic capacity in a process known as dynamic acclimation. Fully developed leaves of Arabidopsis thaliana were exposed to a fourfold increase in light intensity for 7 days to induce high light acclimation. This treatment was subjected to wild-type and a non-acclimating mutant lacking the gpt2 gene. The proteomic responses of the leaves were investigated using label-free mass spectrometry. A large reorganisation of the proteome was shown, with increases in the abundance of proteins of photosynthesis and carbon metabolism. Subtle differences were seen between the WT and gpt2 mutant: in the mutant, an increased stress response was seen, and some differences in the responses of metabolism. Proteomic responses generally correlated with physiological responses.

Project description:We identified a regulator of Arabidopsis thaliana seed germination: FLOE1 (AT4G28300). We used RNA-seq to uncover genes that are differentially regulated in dry seeds, imbibed seeds and seeds imbibed in 220mM NaCl in mutant lines complemented with a ΔDS deletion version of FLOE1 (ΔDS) compared to mutants complemented with a WT version of FLOE1 (+WT).
