Wei et al. discover a new transcriptional and post-translational regulatory module, MaBAH1-MaMYB60, that regulates chlorophyll catabolism and green ripening in bananas under high temperature. By Wei Wei, Yingying Yang, Prakash Lakshmanan, Jianfei Kuang, Wangjin Lu, Xuequn Pang, Jianye Chen and Wei…

Hasegawa, Reyes et al. discover a link between the ubiquitination of a key membrane trafficking regulator and carbon/nitrogen nutrient stress.  Background: Ubiquitination is a post-translational modification that functions in numerous cellular processes by serving as a molecular signal, such as protein…

Plants need to maintain an optimum level of iron (Fe) for normal growth and development. Many Fe-responsive molecular players have been identified in Arabidopsis, including the IRON MAN (IMA) peptides. These peptides are induced by Fe deficiency, but their role in maintaining Fe homeostasis remains poorly…
