Ruiz-Solaní et al. examine how a cysteine protease interacts with stress granules, a type of membrane-less condensate, under heat stress and aging By Nerea Ruiz-Solaní1,2, Laia Armengot1,2 and Núria S. Coll1,3 1 Centre for Research in Agricultural Genomics (CRAG), CSIC-IRTA-UAB-UB, Bellaterra 08193, Spain 2 Department of Genetics, Microbiology and Statistics, Universitat de Barcelona, Barcelona 08028, […]
Wang et al. investigate role of the DCP5-SSF complex in the nucleus https://doi.org/10.1093/plcell/koad151 Wanyi Wang, Chuanhong Wang, Yunhe Wang, Jing Ma. The National Engineering Lab of Crop Stress Resistance Breeding, the School of Life Sciences, Anhui Agricultural University. Background: Typical organelles such as mitochondria and chloroplasts are surrounded by membranes. However, eukaryotic cells also contain […]
Bélanger et al. investigate the silencing of nuclear genes mediated by chloroplast double-stranded RNA transgenes The Plant Cell (2023). https://doi.org/10.1093/plcell/koad165 By Sébastien Bélanger Background: Plants have three genomes: the nuclear, the mitochondrial and the chloroplast genomes. The chloroplast is maternally inherited so transgene insertion into the chloroplast genome prevents its dissemination into the environment. We […]
Cong Liu, Jianzhong Lin, and Xuanming Liu and colleagues show that the protein phosphatase PC1 dephosphorylates and deactivates CatC to negatively regulate H2O2 homeostasis and salt tolerance in rice. https://doi.org/10.1093/plcell/koad167 By Cong Liu, Jianzhong Lin, and Xuanming Liu Background: Soil salinity is a worldwide problem that threatens the growth and yield of crops and prevents […]
Siao et al. demonstrate that single phosphorylation on a protein alters root behavior in Arabidopsis. https://doi.org/10.1093/plcell/koad141 By Wei Siao and Eugenia Russinova, VIB-UGent Center for Plant Systems Biology Background: Plant roots react to their environment by using hormone signaling pathways, which enable their cells to respond to external cues such as gravity and soil properties. […]
Zhang and Jian et al. reveal an epigenetic regulatory mechanism underlying gibberellin signaling-mediated flowering. https://doi.org/10.1093/plcell/koad166 By Chunyu Zhang and Xingliang Hou; South China Botanical Garden, Chinese Academy of Sciences, Guangzhou, China Background: The timing of floral induction is tightly controlled by environmental cues and intrinsic signals. The critical role of gibberellin (GA) in this process […]
