Sucrose is the main photosynthetic product in plants, and acts as a major energy substrate
and signaling regulator of plant growth. Furthermore, sucrose is involved in the responses to …

Major improvements in crop yield are needed to keep pace with population growth and
climate change. While plant breeding efforts have greatly benefited from advances in …

Plants store large amounts of non‐structural carbohydrates (NSC). While multiple functions
of NSC have long been recognized, the interpretation of NSC seasonal dynamics is often …

Growth is a widely used term in plant science and ecology, but it can have different
meanings depending on the context and the spatiotemporal scale of analysis. At the …

Environmental stress constrains sink activity before it affects source activity.•Under drought …

Abstract Trehalose 6-phosphate (Tre6P), the intermediate of trehalose biosynthesis, is an
essential signal metabolite in plants, linking growth and development to carbon status. The …

Starch-rich crops form the basis of our nutrition, but plants have still to yield all their secrets
as to how they make this vital substance. Great progress has been made by studying both …

Despite decades of research on plant drought tolerance, the physiological mechanisms by
which trees succumb to drought are still under debate. We report results from an experiment …
