Yoon, Middleditch, and Rikkerink explore how a Pseudomonas syringae ADP-ribosyl transferase effector modifies RPM1-INTERACTING PROTEIN4 to activate the host R protein RPM1 in disease resistance. Minsoo Yoon, The New Zealand Institute for Plant and Food Research Limited, Auckland, New Zealand Background: Gram-negative bacterial phytopathogens inject specialized proteins (effectors) into their hosts to neutralize defense and […]
Ella Katz1 and Dan J. Kliebenstein1,2. 1Department of Plant Sciences, University of California Davis, Davis, CA, USA 2DynaMo Center of Excellence, University of Copenhagen, Denmark Background: Nitrogen is an essential element for plant growth and development. Nitrogen availability and form affects plant productivity and fitness, especially in changing environments. Plant roots absorb nitrogen from the […]
Bobde, Kumar, and Vasudevan explore the properties of a family of predicted histone deactetlyases, finding them to function as nucleoplasmins. https://doi.org/10.1093/plcell/koac275 Ruchir C. Bobde, Institute of Life Sciences, Bhubaneswar, Odisha – 751023, India; Ashish Kumar, Department of Molecular Biophysics & Biochemistry, Yale University, 260 Whitney Avenue, YSB 345, New Haven, CT, 06511, USA; Dileep Vasudevan, […]
Stepien et al. explore how an auxiliary U1 snRNP protein interacts with RNA polymerase II to regulate co-transcriptional processing of microRNAs. https://doi.org/10.1093/plcell/koac278 Background: MicroRNAs (miRNAs) are single-stranded, usually 21-nt-long, RNAs that regulate basic developmental processes as well as plant responses to fluctuations in environmental conditions. Plant miRNA genes (MIRs) are transcribed by RNA polymerase II […]
Nicolas et al. explore the mechanisms regulating CUP-SHAPED COTYLEDON expression in axillary meristem initiation. https://doi.org/10.1093/plcell/koac269 Antoine Nicolasa,b and Patrick Laufsa a Université Paris-Saclay, INRAE, AgroParisTech, Institut Jean-Pierre Bourgin (IJPB), 78000, Versailles, France. b Université Paris-Saclay, 91405 Orsay, France Background: Stem cells function as sources of new cells for growth or replacing injured tissues. In plants, […]
Mei, Chen, Mao and colleagues harness the power of GWAS to identify gain-of-function allele of TaDTG6-B, which directly activates TaPIF1 transcription and ameliorates drought tolerance. https://doi.org/10.1093/plcell/koac248 Background: Wheat (Triticum aestivum L.) is produced in arid and semi‐arid regions around the world, and water scarcity poses a constant threat to yields, with global climate change and […]
Fang et al. investigate how TZP modulates Arabidopsis seedling growth in response to red light and long days. https://doi.org/10.1093/plcell/koac236 By Weiwei Fang and Eirini Kaiserli, University of Glasgow, Scotland, UK Background: Plants sense, respond and adapt to the environment by changing their body shape and life cycle timing. Plant photoreceptors sense and communicate changes in light […]
