The mechanisms by which plants switch between growth and stress survival remain somewhat enigmatic. Following on from previous studies, Gong et al. revealed that the conserved N-terminal acetyltransferase B (NatB) helps regulate this balance. Arabidopsis mutants lacking the catalytic subunit of NatB,…

Crops such as rice usually flower in the late morning when the ambient temperature rises. Rice plants briefly open their flowers so the mature anthers hang out. However, heat stress can trigger abnormal anther dehiscence, flower infertility, and subsequent yield reduction. Early-morning flowering…

Autophagy is a conserved cellular recycling process that clears unwanted components and helps maintain balance under stress. In plants, immunity protects against invading pathogens, but how autophagy regulates this defense system has remained unclear. To address this question, Clavel and colleagues challenged…

In this interesting Letter to the Editor, Drew and Nagel explore the concept of how identities are established, and draw a comparison between the scientific identity of a person and the cellular identity of a developing guard cell. The article starts by briefly describing the cell autonomous and non-cell…

Endophytic bacteria and fungi, the invisible allies within plant tissues, are emerging as powerful contributors to sustainable agriculture. They can enhance plant defense through multiple mechanisms, including antibiosis, niche competition, and the induction of systemic resistance, thereby reducing reliance…

Plants thrive in constantly changing environments through remarkable trait plasticity, enabling rapid physiological and developmental adaptation to stress. Beyond immediate responses, chromatin regulation provides a mechanism for long-term stress memory via epigenetic changes, allowing plants to “remember”…

In this Perspective article, Stacey Harmer reflects on plant gene regulation driven by the circadian cycle, using a thoughtful approachable tone to describe technological milestones that advanced our understanding of this complex mechanism of gene expression, as well as the work carried out by various…

We are living at a time where insights into plant diversity, function, and evolution are being revealed at an unprecedented rate, thanks largely to the ability to readily sequence and assemble genomes. A new Perspective by Want, along with a large, international group of co-authors, sets out an exciting…
