dc.description.abstract | Root systems play a pivotal role in coupling with drought stress, which is accompanied with
a substantial transcriptome rebuilding in the root tissues. Here, we present the results of global gene
expression profiling of roots of two barley genotypes with contrasting abilities to cope with drought
that were subjected to a mild level of the stress. We concentrate our analysis on gene expression
regulation processes, which allowed the identification of 88 genes from 39 families involved in
transcriptional regulation in roots upon mild drought. They include 13 genes encoding transcription
factors (TFs) from AP2 family represented by ERFs, DREB, or B3 domain-containing TFs, eight
WRKYs, six NACs, five of the HD-domain, MYB or MYB-related, bHLH and bZIP TFs. Also, the
representatives of C3H, CPP, GRAS, LOB-domain, TCP, Ti y, Tubby, and NF-Ys TFs, among others
were found to be regulated by the mild drought in barley roots. We found that drought tolerance
is accompanied with a lower number of gene expression changes than the amount observed in a
susceptible genotype. The better drought acclimation may be related to the activation of transcription
factors involved in the maintenance of primary root growth and in the epigenetic control of chromatin
andDNAmethylation. In addition, our analysis pointed to fives TFs from ERF, LOB, NAC, WRKY and
bHLH families that may be important in the mild but not the severe drought response of barley roots. | pl_PL |
