The drought stress responses of vascular plants are complex regulatory mechanisms
because they include various physiological responses from signal perception under water …

We present unresolved questions in plant abiotic stress biology as posed by 15 research
groups with expertise spanning eco-physiology to cell and molecular biology. Common …

The leaf vasculature plays a key role in solute translocation. Veins consist of at least seven
distinct cell types, with specific roles in transport, metabolism, and signaling. Little is known …

Plant hormones are a group of small signaling molecules produced by plants at very low
concentrations that have the ability to move and function at distal sites. Hormone …

Stomatal responses to humidity, soil moisture and other factors that influence plant water
status are critical drivers of photosynthesis, productivity, water yield, ecohydrology and …

Drought stress is one of the most adverse abiotic stresses that hinder plants' growth and
productivity, threatening sustainable crop production. It impairs normal growth, disturbs …

To understand the integrative networks of signaling molecules, the sites of their biosynthesis
and action must be clarified, particularly for phytohormones such as abscisic acid (ABA). The …

Increasing vulnerability of plants to a variety of stresses such as drought, salt and extreme
temperatures poses a global threat to sustained growth and productivity of major crops. Of …

In angiosperms, floral transition is a key developmental transition from the vegetative to
reproductive growth, and requires precise regulation to maximize the reproductive success …

Plant growth, development, and response to the environment are mediated by a group of
small signaling molecules named hormones. Plants regulate hormone response pathways …
