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 […]
Horticulturalists have long used the technique of meristem culture to propagate plants, as meristems are generally considered to be free of viruses. However, the mechanism by which the stem cells in meristems exclude viruses has been unclear. Here, Incarbone and Bradamante et al. identified roles for RNA-dependent RNA polymerase 1 (RDR1) and salicylic acid (SA) […]
Review: Development of organs for nutrient uptake in parasitic plants and root nodule symbiosis 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 […]
All organisms need nitrogen to produce nucleic and amino acids, but nitrogen-limitation is common for many plants. Although nitrogen is very abundant in the atmosphere, most is inaccessible due to the triple bond that renders N2 relatively inert. Tremendous crop yields in recent decades are attributable largely to the application of ammoinum (NH4+) and other […]
In this essay, Richard Sever (founder of bioRxiv) provides a history of scholarly publishing, starting with the Royal Society Philosophical Transactions (1665). He then provides an overview of the current landscape: not-for-profit society publishers versus for-profit publishers; a breakdown of the real costs incurred by journals; the transition to electronic publishing and archiving; and how […]
