Due to the COVID-19 pandemic many seminar series and conferences have been canceled or postponed. In response to this, and to make sure plant scientists can continue to communicate their latest work to their peers, The American Society of Plant Biologists launched a virtual seminar series via our online…
Plant Biology 2020 Worldwide Summit
Blog
In response to the coronavirus pandemic and social distancing actions taken globally to limit the spread of the virus, the ASPB Board of Directors has decided to convert Plant Biology 2020 to a fully online conference that includes both synchronous (real-time livestream) and asynchronous (on demand)…
XOAT1- At the heart of plant polysaccharide acetylation
Research, The Plant Cell, The Plant Cell: In a NutshellLunin et al. describe a structural and biochemical analysis of the enzyme XOAT1, responsible for the acetylation of the cell wall component xylan, with potential applications in cell wall modification for better biomass valorization.

Review: Evo-physio: on stress responses and the earliest land plants (J. Exp. Bot.)
Plant Science Research WeeklyStreptophytes are a grade of mostly freshwater algae that transitioned into land, a singularity that in turn gave rise to all present terrestrial flora. This passage along the hydrological gradient that culminated in land habitation required key adaptations to overcome previously unencountered terrestrial…
“Order by disorder”- intrinsically disordered proteins (Plant Physiol.)
Plant Science Research WeeklyIntrinsically disordered proteins (IDP) have repetitive protein sequences but lack a defined 3D structure and are deployed to do some challenging functions that a protein with a defined 3D structure cannot perform. One such IDP, Oryza sativa REPETITIVE PROLINE-RICH PROTEIN (OsRePRP) is involved in inhibiting…
MYB30 negatively regulates photomorphogenesis by interacting with PIFs and phytochromes in Arabidopsis (Plant Cell)
Plant Science Research WeeklyPhotomorphogenesis is the growth and development of plants in response to light. The phytochrome family of photoreceptors absorbs red and far-red light, and in Arabidopsis the most abundant phytochromes are phyA and phyB. PHYTOCHROME-INTERACTING FACTORS (PIFs) repress photomorphogenesis, and under red…
Endosidin20 targets the cellulose synthase catalytic domain to inhibit cellulose biosynthesis (Plant Cell)
Plant Science Research WeeklyCellulose is an indispensable component of plant cell wall formation. Cellulose is synthesized at the plasma membrane by a cellulose synthase complex (CSC) made up of at least 18 monomeric cellulose synthases (CESAs). In this study, Huang et al. used a chemical genetic approach to explore the structure…
Mutations PETALOSA cause a dominant double-flower phenotype (J. Exp. Bot.)
Plant Science Research WeeklyFlower development has always been a fascinating field of research in plant biology. While molecular studies in the past focused on regulatory genes involved in the formation of floral organs in model species, current investigations are addressing the genetic determinants underlying the huge variety…
Hydrogen mediates tolerance to cadmium-induced root toxicity (Plant Physiol.)
Plant Science Research WeeklyHeavy metals are a potential threat to human health, especially in areas with high industrial activity where the metals leach in the soil to contaminate underground water. These metals are a threat to plants too, resulting in stunted growth and their eventual death. Wu et al. carried out a mechanistic…
