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…
RNA m6A methylation fine-tunes the jasmonic acid biosynthesis pathway to modulate plant aging
UncategorizedAbstractN6-methyladenosine (m6A) is a context-dependent mRNA modification, yet how its dynamics integrate with endogenous signaling to shape plant development remains unclear. Here, we provide further evidence for HIZ2 as an essential component of the m6A writer complex in Arabidopsis, which methylates…
Nitrate transiently rewires transcription in developing xylem of Populus wood to promote cell expansion via CRF4
UncategorizedAbstractNitrate functions both as a nutrient and a signaling molecule, but how nitrate is perceived and translated into developmental outputs within woody tissues is unknown. Here, we show that developing xylem in hybrid aspen (Populus tremula × P. tremuloides) mounts a rapid, cell-type-specific transcriptional…
The Genome of Bangia fuscopurpurea Illustrates Early Establishment of Multicellularity and Intertidal Adaptation in Red Algae
UncategorizedAbstractThe billion-year-old fossil red alga Bangiomorpha pubescens represents the oldest taxonomically resolved multicellular eukaryote, morphologically indistinguishable from the extant intertidal alga Bangia fuscopurpurea. Here, we report a chromosome-level 107.55 Mb genome assembly of B. fuscopurpurea.…
Precision genetic manipulation: CRISPR toolkits reshape plant biology
UncategorizedAbstractThe emergence of clustered regularly interspaced short palindromic repeats (CRISPR) technology has revolutionized plant genome engineering over the past decade. This review begins by highlighting four seminal early CRISPR studies published in Plant Physiology that laid critical foundations for…
Plant organelle division orchestrated by the mosaic machinery of endosymbiotic relics and eukaryotic host factors
UncategorizedAbstractPlastids retain the imprint of their cyanobacterial ancestry by dividing primarily through binary fission. This process is executed by elaborate division machinery that has continued to evolve since endosymbiosis. Early identification and characterization of the Arabidopsis accumulation and replication…
