Li et al. developed a new tool called LeafNet for segmenting and quantifying stomata and pavement cells. Background: Stomata are microscopic openings in the leaf epidermis that allow for oxygen and carbon dioxide exchange between a plant and the atmosphere. The phenotypes of stomata and the surrounding…

Deng, Chen and colleagues focus on fruit ripening in tomato and describe the role of the EAR domain-containing Ethylene Response Factor SlERF.F12 in recruiting transcriptional repressors to the promoter regions of their targets By Heng Deng, Yao Chen and Mingchun Liu, Key Laboratory of Bio-Resource…

Fuchs et al. report that reductive stress triggers retrograde signaling to safeguard the endoplasmic reticulum by boosting mitochondrial respiratory capacity. Plant Cell https://doi.org/10.1093/plcell/koac017 By Philippe Fuchs, Markus Schwarzländer Background: A strict division into specialized…

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…

Qin et al. identify a mechanism by which ethylene activates gibberellin catabolism to determine primary root growth in rice. Hua Qin and Rongfeng Huang Biotechnology Research Institute, Chinese Academy of Agricultural Sciences Background: The optimization of root architecture is one of the…
