Maintenance of root growth during water deficit can
significantly contribute to yield stability. In this study, total
nine accessions, three each of Triticum monococcum,
Aegilops speltoides and Aegilops tauschii were analysed
for root traits under two levels of osmotic stress at seedling
stage. T. monococcum accession (A2) showed highest
increase in total root growth while 17% and 34% increase in
primary root length was recorded in T. monococcum (A2)
and Ae. speltoides (B3) under osmotic stress. Expression
of BREVIS RADIX (BRX) and NAM/ATAF/CUC 1(NAC1) was
analysed in three diploid accessions with contrasting root
phenotype. BREVIS RADIX, a transcription factor modulating
root length was up regulated in T. monococcum A2
accession while NAC1 expression was up regulated in three
of the accessions under osmotic stress. The accessions
and genes analysed in the study can be good resource to
explore the molecular-genetic mechanism of root growth
under stress.
