Abstract
(Triticum aestivum) (van der Weele et al. 2000; Spollen et al. 2008, Yamaguchi and Sharp 2010; Song et al. 2016; Dalal et al. 2018). Diploid species of wheat have been used as sources of adaptive genes for various biotic and abiotic stresses (Hussien et al. 1997; Reynolds et al. 2007). However, these have not been sufficiently explored for root traits under abiotic stresses. Hence, in this study, diploid wheat species with AA, BB and DD genomes were analysed for root traits under osmotic stress conditions. Expression analysis of two genes viz. BREVIS RADIX (BRX) and, NAM/ATAF/CUC 1 (NAC1), involved in root development in Arabidopsis was also carried out to understand their regulation under osmotic stress.
(小麦)(van der Weele et al. 2000;Spollen et al. 2008, Yamaguchi and Sharp 2010;Song et al. 2016;Dalal et al. 2018)。小麦的二倍体品种已被用作适应各种生物和非生物胁迫的基因来源(Hussien et al. 1997;Reynolds et al. 2007)。然而，这些在非生物胁迫下根系性状的研究还不够充分。因此，本研究对具有AA、BB和DD基因组的二倍体小麦品种在渗透胁迫条件下根系性状进行了分析。通过对拟南芥根系发育相关基因BREVIS RADIX (BRX)和NAM/ATAF/CUC 1 (NAC1)的表达分析，了解它们在渗透胁迫下的调控作用。
