Sometimes more really is better, and I think it’s safe to say that when it comes to genomic information, more is better. Here, Raza et al. highlight the great value of super-pangenomes. A pan-genome is defined as the entire set of genes within a species, created by combining sequences of many individuals. The super-pangenome as […]
With atmospheric CO2 levels increasing 100 times faster than historical levels, much attention has been paid to how crop plants respond to this elevated CO2 (eCO2). For angiosperms, eCO2 leads to increased CO2 assimilation and decreased photorespiration, but over time plants can adapt, leading to lower stomatal conductivity, and ultimately lower rates of nitrogen assimilation. […]
Sometime in the Cretaceous period (dinosaur time!), some monocots acquired a special pathway for carbon fixation, rendering them more efficient particularly in hot or dry environments. In most monocots, carbon is fixed by Rubisco in the mesophyll cells. In the innovative pathway, carbon fixation is split into two cell types, with the initial capture of […]
In Latin, dirigere means “to align or guide”, so in 1997 when a protein was identified that guides the stereoselectivity of another enzyme it was named as a dirigent protein. Subsequent studies found that the Arabidopsis genome encodes 25 dirigent proteins (DPs). In this new work, Gao et al. characterized the expression and function of […]
Recent years have seen a reevaluation of the history and practice of science, including reconsidering who is recognized and why. Science doesn’t exist in a vacuum; it reflects the culture and values of those that practice it. This article, by Mabry et al., is intended to serve as a conversation starter to evaluate scientific botany […]
Review: Till death do us pair: Co-evolution of plant–necrotroph interactions This interesting and well-written review by Derbyshire and Raffaele takes a step back from the molecular interactions between plant and pathogen and discusses them in light of co-evolutionary processes. The review starts with a useful introduction and definition of concepts about “robustness” in biological systems, […]
This review by Cui et al. makes the interesting comparison between the developmental processes involved in root nodule formation and haustoria formation by roots of parasitic plants. As the authors observe, both are organs that are produced for the purpose of nutrient acquisition through “intimate relationships” with other organisms, and initiation of each starts with […]
Without doubt, Arabidopsis thaliana has thoroughly demonstrated its usefulness as a model species. In this interesting article by Mabry et al. (with an impressive author list!), the authors propose to expand the Arabidopsis toolkit to encompass its entire order – its family of families, the Brassicales. Brassicales includes approximately 4700 species in 18 families, including […]
In this Letter to the Editor, Dr. Beronda Montgomery discusses umbrella trees (Musanga cecropioides) as metaphors for how to sustain progress after disruption, specifically the decision by the US Supreme Court to ban the use of race-conscious affirmative action in college admissions. Umbrella trees spring up in disrupted spaces and provide support when resources are […]
