Abstract

Alkalinity constrains crop production. Recently, Zhang et al. reported a negative regulator, Alkaline Tolerance 1 (AT1), attenuating phosphorylation of plasma membrane intrinsic protein (PIP2) to block efflux of intracellular reactive oxygen species (ROS) under alkaline stress and boosting yield of cereal crops by 20-30%. However, further efforts are needed to exploit the application of AT1 in breeding alkaline-tolerant crops.

摘要

碱度限制作物产量。最近，张等人报道了一种负调控因子，耐碱性1（AT1），它在碱性胁迫下减弱质膜内在蛋白（PIP2）的磷酸化，以阻止细胞内活性氧（ROS）外流，并使谷类作物产量提高20%-30%。然而，要开发AT1在耐碱性作物育种中的应用，还需要进一步努力。
