Extensive Transcriptome Changes During Natural Onset and Release of Vegetative Bud Dormancy in Populus
To survive winter, many perennial plants become endodormant, a state of suspended growth maintained even in favorable growing environments. To understand vegetative bud endodormancy, we collected paradormant, endodormant, and ecodormant axillary buds from Populus trees growing under natural conditions. Of 44,441 Populus gene models analyzed using NimbleGen microarrays, we found that 1,362 (3.1%...
متن کاملBiochemical Studies of Bud Dormancy in Tanweed.
By definition, a dormant vegetative bud is viable but it fails to grow when subjected to environmental conditions normally favorable for growth. An understanding of the biochemistry of dormant and active buds is needed to serve as a basis for solving the problem of artificially breaking or inducing bud dormancy. The present study was conducted with the aim of adding to existing knowledge concer...
متن کاملEpigenetic regulation of bud dormancy events in perennial plants
Release of bud dormancy in perennial plants resembles vernalization in Arabidopsis thaliana and cereals. In both cases, a certain period of chilling is required for accomplishing the reproductive phase, and several transcription factors with the MADS-box domain perform a central regulatory role in these processes. The expression of DORMANCY-ASSOCIATED MADS-box (DAM)-related genes has been found...
متن کاملQuantitative trait loci and candidate gene mapping of bud set and bud flush in populus.
The genetic control of bud phenology in hybrid poplar was studied by mapping quantitative trait loci (QTL) affecting the timing of autumn bud set and spring bud flush. The founders of the mapping pedigree were collected from widely separated latitudes to maximize segregating variation for dormancy-related traits in the F(2) generation-the female Populus trichocarpa parent is from Washington Sta...
متن کاملAnalysis of Phenolics of Bud Exudates of Populus simonii and Populus yunnanensis
Bud exudates o f Populus simonii and Populus yunna nensis were similar and contained primarily caffeic acid and its esters together with the flavanones pinocembrin and pinobanksin-3-acetate. The terpenoid patterns o f the specimens examined varied, but this variation was not species related. On the basis o f bud exudate analysis P. simonii and P. yunnanensis may be considered to represent a si...
