Science special issue on Grasses “Grassy biomes—from the steppes of Mongolia to the savannas of Tanzania— are predicted to be the ecosystems hardest hit by the ongoing climate and land use crises,” begins a Perspective by Strömberg and Staver in the August 4, 2022 Science special issue on…

A robust mechanism for resetting juvenility during each generation in Arabidopsis Proper development requires an aging program that is regulated throughout the entire lifespan of an organism as well as across generations. In plants, reproductive cells are derived from differentiated cells, and thus…

Review: Root cell types as an interface for biotic interactions Kawa and Brady review the contributions and responses of individual cell types and cell identities in plant biotic interactions, both pathogenic and commensal. The first step in these interactions is the perception of the microbes by…

Circadian clock component CCA1 is a transcriptional regulator of ABA-mediated abiotic stress tolerance in rice In rice, the circadian clock component gene Circadian Clock Associated 1 (OsCCA1) regulates flowering and nitrogen use efficiency. CCA1 is a MYB family transcription factor that follows a…

Review: Molecular regulators of nitrate response in plants Nitrate is the major form of nitrogen used by plants in an aerobic crop cultivation scenario. Lamig et al. review recent additions to the already vast knowledge of nitrate signaling. A first line of regulation concerns nitrate uptake through…

Systematic characterization of gene function in the photosynthetic alga Chlamydomonas reinhardtii The green alga Chlamydomonas reinhardtii is a useful model system to study photosynthetic organisms, as this single-celled species allows for more high-throughput methods than in multicellular plants,…

Review: Protein phosphorylation “toggle switch” for plant iron balance Protein phosphorylation and dephosphorylation act as a switch regulating a multitude of protein properties, be it their activity, interaction with other proteins, stability, or even cellular localization. This review by Li…

Review: Fire-released seed dormancy - a global synthesis In 1991, Jon E. Keely wrote the first review about the role of fire as a dormancy-breaking cue in California's Mediterranean ecosystems. In this review, almost 30 years after Keely's work, Pausas and Lamont provide us with an updated and worldwide…
