Plant Physiology Webinar: Celebrating the October 2022 Focus Issue on Circadian Rhythms (Part 2) Recorded Tuesday, October 18 2022 About this Webinar Circadian rhythms are ubiquitous across eukaryotes, but are perhaps of particular importance to plants. In all model organisms studied to date, these roughly 24-hour rhythms in physiology, growth, or development are generated by cell-autonomous […]
Arabidopsis thaliana has been established as a versatile and important model plant species, with abundant genetic and genomic resources. Through RNA sequencing, Verhoeven et al. identified an unexpected and previously unnoticed latent comovirus (the name “como” derives from cowpea mosaic virus) lurking in the genome of this well-studied plant, which was detected in both laboratory […]
Genome-edited rice deficient in two 4-COUMARATE:COENZYME A LIGASE genes displays diverse lignin alterations Lignin is one of the most important end-products of the cinnamate/monolignol pathway and it is abundant in the secondary cell wall of vascular plants. In grasses, lignins are derived from monolignols, p-hydroxycinnamates, and a flavonoid tricin. In the proposed cinnamate/monolignol pathway, 4-COUMARATE:COENZYME […]

Plant Physiology Webinar: Celebrating the September 2022 Focus Issue on Evolution of Plant Structure and Function Recorded Friday, September 16, 2022 About this Webinar Plant morphology, physiology, and development are shaped by a combination of internal, external, and historical factors that have led to the remarkable diversity of structure and function we can observe […]
There is a clear need to synergize advances from cutting-edge genomic approaches with the needs and knowledge of growers, particularly small-holder growers who have access to much of a crop’s genetic diversity. Here, Woldeyohannes, Iohannes et al. took a transdisciplinary approach to explore the breeding potential of teff (Eragrostis tef), a cereal crop widely grown […]
In January 2019, a workshop was convened to explore strategies to address inclusivity in the plant sciences, and the recommendations emerging from this workshop are presented in a new report by Henkhaus et al. The authors recognize that this is an expansive challenge and requires action on many fronts, which they group into four areas: […]
One of the longstanding questions in plant biology concernes how auxin coordinates both gene expression in the nucleus and the so-called fast responses at the cell periphery including proton extrusion and cytoskeletal rearrangements. At this point the nuclear branch is well understood, but the cell periphery responses have proven to be be problematic. Fifty years […]
The September 2022 issue of Nature Plants includes two papers describing the analysis of homosporous fern genomes. Ferns are interesting for many reasons including the diversity of the clade, their typically very large genomes, their often free-living gametophytes, and in many cases, homospory (a single type of spore), which is distinct from angiosperm’s heterospory (separate […]
