Project description:FLP and MYB88 are two paralogous MYB proteins, regulating the symmetric division of guard mother cell during Arabidopsis stomatal development. To understand their molecular functions, we performed genome-wide identification of FLP/MYB88 binding targets using ChIP-chip with FLP/MYB88 antibody. By comparing ChIP-chip between wild-type and flp-1 myb88 lines, a total genes were identified as putative direct targets for FLP/MYB88.
Project description:Autophagy involves massive degradation of intracellular components and functions as a conserved system that helps cells to adapt to adverse conditions. In Arabidopsis thaliana, submergence induces the transcription of autophagy-related (ATG) genes and the formation of autophagosomes. To study the role of autophagy during submergence, we performed transcriptome analysis with atg5, an autophagy-defective mutant, under submergence conditions. Our data showed that submergence changed the expression profile of DEG in the atg5 versus wild-type.
Project description:Arabidopsis, at the 10 leaf stage, was given kept under control growth conditions, complete darkness, or complete darkness together with complete submergence for 4 hours. These treatments were given to eight accession varying in tolerance to complete submergence, namely Cvi-0, Bay-0, Ita-0, Col(gl), Kas-1, Lp2-6, Ws-2, C24. Additionally, both roots or entire shoots were harvested. Overall this allowed the identification of conserved responses to darkness and submergence in addition to variation in the transcriptomic response potentially related to tolerance to complete submergence. An additional layer of post transcriptional regulation (alternative splicing) was also uncovered by this data.
