Unraveling bHLH transcription factor-mediated maize anther development

Nan, Teng et al. uncover bHLH-regulated genetic networks that sequentially control maize anther development.  By Chong Teng (DDPSC, MO), Guo-Ling Nan (Stanford University, CA), Blake Meyers (DDPSC and University of Missouri–Columbia, MO), and Virginia Walbot (Stanford University, CA)  Background: Correct spatiotemporal development of somatic tissues in the anther is necessary for successful fertile pollen production. […]

Make two from one: How embryonic algal cells divide in an orchestrated flow of subcellular structures

Von der Heyde and Hallmann uncover the enormous dynamics of early cell divisions in Volvox embryos.  https://doi.org/10.1093/plcell/koac004 Eva Laura von der Heyde and Armin Hallmann Department of Cellular and Developmental Biology of Plants, University of Bielefeld, Universitätsstr. 25, 33615 Bielefeld, Germany Background: Mitosis, a type of cell division, is fundamental to all eukaryotic life and […]

The straw that breaks the camel’s back

Wang et al. investigate the downstream effectors of CLE peptide ligand-mediated meristem homeostasis. https://doi.org/10.1093/plcell/koab315 By Wenping Wang, Chong Hu, Xiaoping Gou and Jing Yi Ministry of Education Key Laboratory of Cell Activities and Stress Adaptations, School of Life Sciences, Lanzhou University, Lanzhou 730000, China. Background: Throughout their lifespans, plants continually initiate new organs. This process […]

A module controlling endoreduplication and cell growth in Arabidopsis

Jiang et al. discover a module controlling endoreduplication, a process in which DNA replication occurs in the absence of mitosis. Background: Organ size is coordinately regulated by both cell number and cell size. Endoreduplication is often associated with cell size in plants and animals, but the mechanisms underlying plant endoreduplication are not fully understood. CDKB1;1 […]

The chloroplast protein biogenesis network at the ribosome during heat acclimation

By Raphael Tröscha, Fabian Riesb, Lisa Désirée Westrichb, Felix Willmundb, a Max Planck Institute of Molecular Plant Physiology, Am Mühlenberg 1, 14476 Potsdam-Golm, Germany; b Molecular Genetics of Eukaryotes, University of Kaiserslautern, Paul-Ehrlich-Str. 23, 67663 Kaiserslautern, Germany Trösch, Ries and Westrich explore the response of chloroplast transcript accumulation and translation when exposed to moderate heat […]

Bypassing reproductive barriers in hybrid seeds

Huc et al. discover a method for bypassing the triploid block via chemically induced epimutagenesis using 5-Azacytidine. Background: Hybridization of plants with different chromosome numbers is often hindered by reproductive barriers established after fertilization. This is because the correct balance between paternal and maternal genomes is disrupted in the endosperm of the developing seed, which […]

Soybean ACBPs Sort out the Salt with Oxylipins

Lung et al. demonstrate that acyl-CoA-binding proteins initiate oxylipin signaling to help soybean adapt to the salty environment. The Plant Cell (2021) https://doi.org/10.1093/plcell/koab306 By Shiu-Cheung Lung and Mee-Len Chye, The University of Hong Kong, Pokfulam, Hong Kong, China Background: High salt in soil challenges the performance of many crop plants including soybean. Plants adapt to […]

TOR promotes guard cell starch degradation and stomatal opening

Han et al demonstrate that sugar-activated TOR promotes guard cell starch degradation and stomatal opening. Chao Han and Ming-yi Bai The Key Laboratory of Plant Development and Environmental Adaptation Biology, Ministry of Education, School of Life Sciences, Shandong University, Qingdao, 266237, China. Background: Starch is widely present in guard cells of different plant species. Rapid […]
