Novel aspects of transcriptional regulation in the winter survival and maintenance mechanism of perennial woody plants, poplar.

ABSTRACT: Winter survival and maintenance strategy is crucial in temperate woody plants. Here, we demonstrate novel aspects of the transcriptional regulations adopted by perennial tree species in winter/dormancy, employing a biochemical and whole transcriptome analysis. As expected, genes related to cold hardiness and defense are over-represented. Interestingly, carbohydrate biosynthesis and transport-related genes were very actively expressed in winter/dormancy. Further biochemical analyses verified the dormancy/winter transcription phenotype. Furthermore, dormancy/winter preferential expression of genes involved in the cell wall biosynthesis/modification, circadian rhythm, the indirect transcriptional regulation (RNA metabolism), and chromatin modification/remodeling were identified.
