TaMYB72 directly activates the expression of TaFT to promote heading and enhance grain yield traits in wheat (Triticum aestivum L.).

This article discusses the role of the transcription factor TaMYB72 in promoting heading and enhancing grain yield traits in wheat. The researchers used CRISPR/Cas9-based gene editing to create knockout mutants of TaMYB72 and found that these mutants displayed later heading dates and increased grain yield traits compared to the wild-type plants. The study also revealed that TaMYB72 directly activates the expression of TaFT, a gene involved in flowering and spikelet development, to regulate the height and yield traits of wheat. These findings provide valuable insights into the genetic basis of grain yield traits and heading date in wheat, and suggest TaMYB72 as a potential target gene for increasing grain yield in breeding programs.
