Crowd control by DCP5 - a new cytoplasmic osmosensor
Plant Science Research Weekly, Upcoming Plantae PresentsOsmosis, driving water uptake and transport, is crucial for plants. It supports nutrient uptake, turgidity, and overall plant health. In hyperosmotic conditions, caused by drought, salinity, and cold stress, water loss triggers osmotic responses. A key question is: what sensors detect osmotic changes?…
Functional insights into the TPLATE complex: A key player in clathrin-mediated endocytosis in plant cells
Plant Science Research WeeklyTransporting cargo within a cell may seem straightforward, but it is actually an intricate task. At the plasma membrane in plant cells, this complexity is navigated by a process known as clathrin-mediated endocytosis. Central to this process are two key players: adapter protein AP-2 and the TSET/TPLATE…
Phase separation determining meiotic interference-sensitive meiotic crossover formation
Plant Science Research WeeklyIn sexual reproduction, meiosis creates new combinations between homologs and diversifies the genetic information among gametes and progenies. Most meiotic crossovers (COs) are mediated by a group of ZMM factors, including HUMAN ENHANCER of INVASION-10 (HEI10), which is suggested to concentrate at CO…
Focus Issue: Biomolecular Condensates
Plant Science Research WeeklyAlthough The Plant Cell Focus Issue on Biomolecular Condensates officially comes out in September, due to the idiosyncrasies of publishing many of the articles are already available online, and I’m highlighting them now because this topic is also the focus of a plenary session at the Plant Biology…
Pre-mRNA retention in Cajal bodies as a mechanism of post-transcriptional regulation of gene expression during development
The Plant Cell: In a NutshellBy Dariusz Jan Smoliński, Nicolaus Copernicus University, Poland
Rudzka and colleagues characterize the retention of Sm pre-mRNAs that retain introns in Cajal bodies over the course of microsporocyte development in European larch (Larix decidua)
Background: Reports in both animals and plants have…
