Plants are immobile and their cells are contained within cell walls, yet they demonstrate vast post-embryonic developmental plasticity. Evidence shows that the fate of the cell is likely determined by its location within the plant, but the specific mechanisms and pathways involved are currently unknown.…

As rice has expanded northwards from its center of origin, it has been exposed to deeper and longer periods of cold. Male fertility is particularly sensitive to cold. Song et al. designed a clever strategy to study mechanisms of cold tolerance. They subjected meiotic-stage cold-sensitive rice varieties…

Legume plants are renowned for their ability to form symbiotic relationships with nitrogen-fixing bacteria (rhizobia) in specialized root tissues called nodules. This symbiosis enables the conversion of atmospheric nitrogen into ammonia, a form of nitrogen that plants can readily use for growth. This…

At the height of the Covid pandemic, epidemiologists carried out mass sequencing of the circulating virus populations to track their movements and the emergence of new variants. Such molecular epidemiological studies are rarer for plant pathogens but can be equally effective in learning about their patterns…

Review: Gene discovery, from Arabidopsis to crops This year marks the 25th anniversary of the publication of the first genome sequence of a plant, Arabidopsis thaliana, (see https://doi.org/10.1038/35048692). As this review by Bevan et al. observes, this exciting accomplishment was met with some skepticism…

The May 2025 issue of The Plant Cell has a focus on Arabidopsis and how this simple model plant has had an outsized impact on our understanding of pretty much everything botanical (and beyond). Alongside several articles highlighting this impact, this review by Roeder et al. features eight short vignettes…

Plant biologists are critical players in the pursuit of crop enhancement and other real-world solutions to today’s pressing problems, yet few of us know how to translate our research into tangible economic or social benefits. This useful and engaging article by Jonathan Napier walks us through the…

Mitochondria are vital energy-producing organelles that depend on precise RNA processing for function. In this study, Peng et al. identify PPR767, a mitochondria-localized E-type pentatricopeptide repeat (PPR) protein in rice, as a key regulator of plant architecture and drought tolerance. Loss-of-function…
