Dual benefits of STOP1-NRT1.1 in response to acidic stress

Ye et al. investigate H+ tolerance mechanisms in Arabidopsis The Plant Cell (2021) Plant Cell https://doi.org/10.1093/plcell/koab226 By Jia Yuan Ye and Chong Wei Jin Background: Acid soils cover nearly half of the world’s arable lands. Application of urea-N and ammonium-N fertilizers markedly increases soil acidification due to proton (H+) generation from nitrification. High H+ concentrations […]

The queen’s crown: Team-building the stigma at the top of the pistil

Ballester et al. reveal how stigma development in Arabidopsis requires the formation of different higher-order transcription factor complexes of increasing complexity. https://doi.org/10.1093/plcell/koab236  By Cristina Ferrándiz Instituto de Biología Molecular y Celular de Plantas, CSIC-UPV Background: The stigma is a specialized tissue that forms at the top of the pistil, the female organ of the flower. […]

Linking low energy sensing to chromatin modification and gene activity in rice

Wang and colleagues investigated the starvation response of rice seedlings. By Wentao Wang and Yue Lu Background: For survival and growth, cells of all living organisms must balance their energy consumption and supply. Although energetically autonomous (through photosynthesis), plants are continuously challenged by their changing environment and especially by diverse stresses that affect plant physiology […]

VDAL transgenic cotton exhibits tolerance to Verticillium wilt caused by Verticillium dahliae

Ma et al. investigate a VDAL protein from Verticillium dahliae that can enhance plant disease. Plant Cell https://doi.org/10.1093/plcell/koab221 By Aifang Ma, Zhizhong Gong and Junsheng Qi Background: Verticillium wilt, also called a plant cancer disease, causes massive losses in multiple crops including cotton. Increasing the plant resistance to Verticillium wilt is a critical challenge worldwide. […]

Fishing out virus replication complexes

Incarbone et al. use an epitope-tagged protein that binds double-stranded RNAs to fish out viral replication complexes and identify the associated proteins. Plant Cell. https://doi.org/10.1093/plcell/koab214 Marco Incarbone (GMI, Vienna) and Christophe Ritzenthaler (IBMP, Strasbourg) Background: Viruses can cause devastating diseases in plants, and understanding their molecular workings is of great importance. All RNA viruses, which […]

Winter is coming: It’s time to “CRY”

Li et al. reveal how the cryptochrome CRY2 regulates freezing tolerance in Arabidopsis. https://doi.org/10.1093/plcell/koab215  By Youping Li Background: Cold acclimation via exposure to non-lethal low temperatures enhances frost resistance in plants. This process requires light; however, we know very little about the underlying mechanism. The red light photoreceptor phyB functions as a thermosensor to perceive […]

An E3 ubiquitin ligase modulates brassinosteroid signaling by targeting the transcription factor BES1 to selective autophagy under sucrose starvation

Wang et al. identify a mechanism by which plants reduce growth under sucrose starvation conditions. Plant Cell. https://doi.org/10.1093/plcell/koab210 by Ping Wang and Yanhai Yin (Iowa State University)  Background: Plants fine-tune their growth and stress-response programs to adapt to the environment. Brassinosteroids (BRs), a major family of steroid growth-promoting plant hormones, are implicated in stress responses. […]

COMPASS functions as a module of the INO80 complex

Shang et al. explore the function of a chromatin-remodeling complex in the regulation of gene expression. Plant Cell. https://doi.org/10.1093/plcell/koab187 By Ji-Yun Shang and Xin-Jian He  Background: In eukaryotic cells, the INO80 chromatin remodeling complex uses energy derived from ATP hydrolysis to change chromatin structure and the accessibility of chromatin-related proteins to DNA. The histone methyltransferase […]

Engineering a wheat spike

Li et al. investigated genes regulating wheat spike development and found that SQUAMOSA and SVP genes control the development of normal spikes. Plant Cell. https://doi.org/10.1093/plcell/koab243 By Jorge Dubcovsky, Kun Li and Juan Manuel Debernardi, University of California, Davis, CA, USA Background: More than 750,000,000 tons of wheat grains are produced globally each year. These grains […]
