Regulatory changes in TaSNAC8-6A are associated with drought tolerance in wheat seedlings.

ABSTRACT: Wheat is a staple crop produced in arid and semi-arid areas worldwide, and its production is frequently compromised by water scarcity. Thus, increased drought tolerance is a priority objective for wheat breeding programmes, and among their targets, the NAC transcription factors have been demonstrated to contribute to plant drought response. However, natural sequence variations in these genes have been largely unexplored for their potential roles in drought tolerance. Here, we conducted a candidate gene association analysis of the stress-responsive NAC gene subfamily in a wheat panel consisting of 700 varieties collected worldwide. We identified a drought responsive gene, TaSNAC8-6A, that is tightly associated with drought tolerance in wheat seedlings. Further analysis found that a favourab
