Abstract:
... Common wheat (Triticum aestivum L.) is an important staple food crop worldwide. Lateral roots (LRs), as the major component of root architecture, affect water and nutrient uptake in wheat. The phytohormone ethylene is known to affect LR formation; however, the factor(s) modulating ethylene during this process have not yet been elucidated in wheat. Here we identified wheat TaWRKY51 as a key factor ...
