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

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…
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…
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

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…
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.…
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…
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
