Description
Understanding the genetic control of tree dormancy and flowering is tantamount to implementing
strategies to improve fruit and forest tree performance in the Anthropocene. Significant inroads
have been achieved in uncovering the networks of genes and their actions governing
phenological traits in model systems but we need to translate these advances to tree species that
underpin our agricultural and forest industries, particularly in light of the challenges posed by a
rapidly warming climate. Leveraging these model system advances, genes and networks
controlling these traits are being assessed in fruit and forest tree materials that exhibit phenotypic
variation in dormancy and flowering through QTL mapping and RNAseq analyses.
The work objectives for this cooperative are as follows.
1) Dr. T. Zhebentyayeva who is currently working on these traits in both fruiting and forest
trees will analyze RNAseq data generated by the AFRS of fruit tree buds progressing
from late August through budburst in the spring to characterize the gene action of specific
dormancy and flowering associated genes and gene networks and to identify additionally
important genes and networks potentially controlling these traits.
2) Dr. T. Zhebentyayeva will integrate data from previous and proposed studies in fruit trees
with datasets of mapped genomic intervals controlling these traits in key forest tree
species under study at the FHC to uncover genes and networks in common for controlling
these traits. These will be targets of selections for improvement of tree performance.
3) Dr. T. Zhebentyayeva will also participate in data analyses associated with the AFRS’s
efforts at single cell expression analyses that has application to furthering our
understanding of environmental sensing and response systems in tissue specific control of
gene action in complex tissues such as floral buds.
4) Dr. T. Zhebentyayeva will participate and assist directly in manuscript and proposal
development and submission.
