A tug-of-war in the viral replication factory: How a viral protein interferes with stress granules

/in /by

Hoffmann et al. explore replication of Cauliflower mosaic virus and how virus replication intersects RNA granule biology. https://doi.org/10.1093/plcell/koad101 Gesa Hoffmann and Anders Hafrén, Swedish University of Agricultural Sciences Background: Regulating RNA abundance and its availability for translation is one of the main struggles between virus and host during plant virus infections. The pararetrovirus Cauliflower mosaic […]

SnRK1 and TOR—in a different light

/in /by

Saile et al. explore the role of SnRK1 and TOR in light-dependent seedling development and splicing. https://doi.org/10.1093/plcell/koad168 Jennifer Saile and Andreas Wachter Institute for Molecular Physiology (imP), University of Mainz Background: Plants adjust their development to light and metabolic signals to make best use of their available resources. Dark-grown seedlings undergo etiolation with increased hypocotyl […]

All in good time: Timing gene activation during early flower development

/in /by

Pelayo et al. explore the function of a biological timer that activates key genes for flowering. Margaret Anne Pelayo, Nara Institute of Science and Technology https://doi.org/10.1093/plcell/koad123 Background: For flowers to form, the floral meristem (floral stem cells) must irreversibly commit to becoming cells making up the various floral organs (sepals, petals, stamens, and carpels), a […]

A transcriptional hub integrates multiple hormone signaling pathways in rice

Cao and Bai et al. reveal a conserved enzyme that makes many algae appear brown as opposed to green typical of land plants. https://doi.org/10.1093/plcell/koad116 Graham Peers1, Martin Lohr2, Xiaobo Li3,4 1 Department of Biology, Colorado State University; Fort Collins, USA. 2 Institut für Molekulare Physiologie, Johannes Gutenberg-University; Mainz, Germany. 3 Key Laboratory of Growth Regulation […]

Targeting of plasmodesmal proteins requires unconventional signals

/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

/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, […]
