Targeting of plasmodesmal proteins requires unconventional signals

September 22, 2023 in /by

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

September 22, 2023 in /by

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

September 18, 2023 in /by

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

September 15, 2023 in /by

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

September 14, 2023 in /by

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

September 13, 2023 in /by

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

September 12, 2023 in /by

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

September 11, 2023 in /by

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

September 11, 2023 in /by

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 […]
