The transcription factor SbbHLH168 enhances salt tolerance by coordinating ion homeostasis and lignin content in sorghum
Soil salinization is an escalating global threat to crop productivity. Here, we demonstrate that the sorghum bHLH transcription factor SbbHLH168 is a central regulator of salt-stress tolerance. SbbHLH168 is nuclear-localized, constitutively expressed in all organs and rapidly up-regulated by NaCl. Overexpression of Sbb...
