Targeting of plasmodesmal proteins requires unconventional signals

Gabriel Robles Luna, Jung-Youn Lee and colleagues discover that proteins carry targeting signals that send them to plasmodesmata, but these signals show no sequence conservation. https://doi.org/10.1093/plcell/koad152 Gabriel Robles Luna1, Jiefu Li3, Xu Wang1, Li Liao2,3, and Jung-Youn Lee1,2,4*          1Department of Plant and Soil Sciences, University of Delaware; Newark, DE19716, USA 2Delaware Biotechnology Institute, University of […]

Nascent pri-miRNAs and HYL1 act as a scaffold to recruit transcriptional regulators to miRNA loci

Park et al. reveal how a microprocessor component and a histone deacetylase act in microRNA biogenesis under stress. Background: MicroRNAs (miRNAs) are small noncoding RNAs with a length of 21–24 nucleotides that play critical roles in mRNA silencing and translational suppression. In plants, miRNAs are transcribed by RNA polymerase II and processed by the microprocessor, […]

Sending out an SOS: Interplay between salt stress and light signaling

Ma, Han, et al. explore the molecular mechanism underlying the interplay between light and salt stress pathways. Background: The Salt Overly Sensitive (SOS) pathway is evolutionarily conserved and essential for plant adaptation to salt stress. The protein kinase SOS2 functions as a network hub in the SOS pathway, and its kinase activity is rapidly activated […]

SOS and SAS: The interaction of shade avoidance and salt tolerance responses

Han, Ma, et al. reveal the mechanistic connection between shade avoidance responses and salt-induced responses. https://doi.org/10.1093/plcell/koad119 Background: Sun-loving plants compete with their neighbors for sunlight by initiating shade avoidance syndrome (SAS). Phytochromes are plant photoreceptors that play a predominant role in perceiving the shaded environments and triggering SAS. Phytochrome-interacting factors (PIFs) are a subset of […]

CYCLOIDEA-like genes control multiple floral traits

Yang, Wang, Liu, et al. reveal that CYCLOIDEA-like genes control the genetic correlation of floral symmetry, floral orientation, and nectar guide patterns. https://doi.org/10.1093/plcell/koad115 By Xia Yang1,2 and Yin-Zheng Wang1,2,3 Institutions: 1 State Key Laboratory of Systematic and Evolutionary Botany, Institute of Botany, Chinese Academy of Sciences, Xiangshan, Beijing 100093, China 2 China National Botanical Garden, […]

Proximity labeling to examine viral replication complexes

Q. Zhang, Z. Wen, and X. Zhang, et al. use proximity labeling with the TurboID system to identify proteins that are important for replication in plant viruses. https://doi.org/10.1093/plcell/koad146 Yongliang Zhang1, Xiaofeng Wang2 1 State Key Laboratory of Plant Environmental Resilience and Ministry of Agriculture Key Laboratory of Soil Microbiology, College of Biological Sciences, China Agricultural […]

NAC-CYP Mediates Soybean Nodule Senescence

Yu et al. show that activation of the expression of cysteine protease genes by GmNAC039 and GmNAC018 is required for soybean nodule senescence The Plant Cell (2023). https://doi.org/10.1093/plcell/koad129 By H Yu and Y Cao Background: Soybean (Glycine max) roots have nodules in which symbiotic bacteria reduce nitrogen gas into ammonium, which nourishes the plants. The […]

Turnover of Complex I is regulated by FTSH3 that recognises the PSST subunit

Ghifari et al. explore the mechanisms of Complex I disassembly and turnover. https://doi.org/10.1093/plcell/koad128 Abi S. Ghifari and Monika W Murcha School of Molecular Sciences, The University of Western Australia Background: Oxidative phosphorylation (OXPHOS) is the central process of aerobic respiration in plant mitochondria. Complex I, the first entry point and largest complex of the OXPHOS […]

Enhanced discovery of plant RNA-binding proteins

Zhang, Zu, et al. develop a method to identify RNA-binding proteins that bind poly(A) and non-poly(A) RNAs. Yong Zhang and Devinder Sandhu; University of California Riverside and US Salinity Laboratory (USDA-ARS), Riverside, CA, USA Background: RNA-binding proteins (RBPs) are important for controlling the fate of cells and for regulating important processes during development. Scientists study […]
