GWAS on multiple traits identifies mitochondrial ACONITASE3 as important for acclimation to submergence stress (Plant Physiol.)
Plant Science Research WeeklyClimate change is affecting the frequency and intensity of extreme climatic events such as floods, reducing crop production severely. Submergence might lead to a lack of O2, light, and carbon dioxide, having an impact on the carbohydrate content and ATP synthesis. In this work, Xiangxiang et al. characterise…
