Project description:Bud dormancy is a crucial stage in perennial trees and allows survival over winter and optimal subsequent flowering and fruit production. Environmental conditions, and in particular temperature, have been shown to influence bud dormancy. Recent work highlighted some physiological and molecular events happening during bud dormancy in trees. However, we still lack a global understanding of transcriptional changes happening during bud dormancy. We conducted a fine tune temporal transcriptomic analysis of sweet cherry (Prunus avium L.) flower buds from bud organogenesis until the end of bud dormancy using next-generation sequencing. We observe that buds in organogenesis, paradormancy, endodormancy and ecodormancy are characterised by distinct transcriptional states, and associated with different pathways. We further identified that endodormancy can be separated in two phases based on its transcriptomic state: early and late endodormancy. We also found that transcriptional profiles of just 7 genes are enough to predict the main cherry tree flower buds dormancy stages. Our results indicate that transcriptional changes happening during dormancy are robust and conserved between different sweet cherry cultivars. Our work also sets the stage for the development of a fast and cost effective diagnostic tool to molecularly define the flower bud stage in cherry trees.

Project description:In plant axillary bud dormancy and outgrowth are regulated by phytohoromones, but it is still unknown about its molecular mechanism. We reveal that Arabidopsis axillary buds located at axil of rosette leaves show dormancy and that this is broken by the decapitation of main stem, resulting in the bud outgrowth. To investigate about the molecular mechanisms of dormancy and outgrowth, we carried out gene expression analysis during axillary shoot outgrowth in Arabidopsis wild type Columbia accession. Since axillary buds did not initiate outgrowth (dormancy) at 5 day after bolting of main stem, we used 5-day bolted plants as a control (before decapitation). Then, main stems were decapitated, and axillary shoots were collected at 24 hours after decapitation (named as growing shoot). Total RNA was prepared from either control or growing shoots and used for the microarray analysis. We carried out duplicate microarray analysis using independent plant materials.Ref):Tatematsu et al., Plant Physiol. 138: 757-766 (2005). Keywords: Expression profilling by array

Project description:We investigated differential gene expression patterns in Populus vegetative buds between paradormant, endodormant, and ecodormant dormancy states. Our primary objectives were to (1) identify which individual genes, biological processes, molecular functions, and regulatory pathways were differentially expressed among dormancy states, (2) classify the differentially expressed genes into contrasting gene expression patterns, and (3) identify cis-acting elements associated with each gene expression group. For more details consult Howe et al. (Frontiers in Plant Science, 2015, pending).
