Knock-down the expression of TaH2B-7D using virus-induced gene silencing reduces wheat drought tolerance

摘要

BackgroundDrought is a major abiotic stress affecting global wheat (Triticum aestivum L.) production. Exploration of drought-tolerant genes is essential for the genetic improvement of drought tolerance in wheat. Previous studies have shown that some histone encoding genes are involved in plant drought tolerance. However, whether the H2B family genes are involved in drought stress response remains unclear.
