How chromatin changes shift CHH methylation pathways in soybean
Plant Science Research WeeklyDECREASED IN DNA METHYLATION 1 (DDM1) is a chromatin remodeler that regulates nucleosome organization and facilitates access of DNA methyltransferases to heterochromatic regions enriched in transposable elements (TEs), contributing to DNA methylation, TE silencing, and genome stability. In plants, CHH…
Could the transcription factor HHO5 hold the key to breaking fertilizer dependency?
Plant Science Research WeeklyEfficient nitrogen uptake is essential for plant growth. Hinckley et al. have characterized HRS1 HOMOLOG 5 (HHO5), a transcription factor in Arabidopsis that had been previously overlooked compared to the NIGT1 family. Through a single T-DNA insertion mutation, the authors show HHO5 acts as a non-redundant…
Cellulose synthase complexes and remorins anchor the membrane to the cell wall under water stress
Plant Science Research WeeklyPlant cells are under constant turgor pressure that pushes the plasma membrane tightly against the cell wall. Under severe water loss, cells shrink and membrane retracts without fully detaching from the wall. Narrow bands known as Hechtian strands remain tethered to the cell wall at membrane/wall contact…
ULTRAPETALA1: A molecular regulator that fine-tunes the transition to flowering
Plant Science Research WeeklyPlants need to carefully control which genes are active as they grow and switch from one developmental stage to another. A new study by Geshkovski et al. reveals that ULTRAPETALA1 (ULT1), previously thought to mainly counteract gene silencing, can also promote gene silencing by working directly with…
Rhodanobacter enhances drought tolerance through a KAI2-interacting isoflavone
Plant Science Research WeeklyA new paper by Sun et al. demonstrates a pathway through which drought tolerance in Arabidopsis is influenced by soil microbiota. Using transcriptomic and metabolomic analyses, Sun et al. identified a strain of Rhodanobacter that is recruited to the rhizosphere of drought-stressed plants and can help…
Increases in cereal seed size were likely a plastic response before eventual genetic selection
Plant Science Research WeeklyPlant domestication was a significant event in human history that occurred at multiple locations and time points. Barley, emmer wheat, and einkorn wheat are cereals that were domesticated about 10,000 years ago in southwest Asia, in a region called the Fertile Crescent. The hallmarks of cereal domestication…

WWR Full PostReview: Plant digital twins, the future of crop production
Imagine how cool it would be if, just like we check weather apps before going out, we could “grow” a plant in our computer before planting it into our backyard, in order to predict its future success. Pauli et al. discuss this possibility…
Review: Tracing the evolution of plant cell types
Plant Science Research WeeklyPlants. When we read this word, what comes to mind might be a rose, a tomato plant, or an oak tree. But plants belong to a green lineage that is far more diverse than what we encounter in daily life. This lineage also includes unicellular green algae. The evolution of the green lineage spans over a billion…
Review: Shuffling genes for better breeds
Plant Science Research WeeklyDuring meiosis, the cell division process that generates four distinct gametes, chromosomes exchange genetic material during homologous recombination. Homologous recombination is a complex process that is tightly controlled in location and frequency – each chromosome must have at least one crossover…
