Review: Epidermis-derived secretory structures I’d never thought about the fact that there are two distinct types of epidermal-derived secretory structures, both mainly involved in stress responses and defense. Glandular trichomes (GTs) are well known structures that protrude outwards, but they…

Behind the Plant Physiology manuscripts are researchers, professors, professionals and students dedicated to advancing the field of plant science. You’ve seen our First Authors on Bluesky, Facebook, and Twitter — now, read more about why they chose to pursue plant sciences and click on the links…

This review, by Tadao Asami, looks back at his career as a scientist who designs and synthesizes small, physiologically active molecules with applications in research and agriculture.  It’s an impressive history documenting how the methods used for such rational design have evolved over the past five…

A major challenge in plant biology is observing molecular events. Reporter systems such as GUS and GFP have underpinned breakthroughs in gene regulation, cell signalling and development, yet each has its constraints: Fluorescent proteins demand microscopes and low background autofluorescence, and GUS…

Designing small-molecule biosensors that are both sensitive and versatile remains a central challenge in synthetic biology, yet such tools are indispensable for environmental monitoring, cellular control, and emerging biotechnologies. In this study, Tian and colleagues exploit an unexpected feature of…

Nitrogen and phosphorus are essential macronutrients for wheat (Triticum aestivum L.) growth and development, and phosphorus deficiency is often associated with purple pigmentation in leaves due to anthocyanin accumulation. For farmers and growers, this pigmentation can be read as a sign of phosphorus…

Elucidating the pathways in which plants can recognize and respond to heat stress is a key step in developing more resilient plants and crops. Work by Li et al. provides a more in-depth understanding of the early factors in heat stress-responsive (HSR) gene expression in Arabidopsis. They first identified…

When we talk of pollination, we often imagine colorful flowers and scents that attract insects to the flowers. However, flowers are a hallmark of angiosperms. How cone-bearing gymnosperms attract their pollinators has been a long-standing question. In a recent study, Valencia-Montoya et al. investigated…
