Plant hormones are signalling compounds that regulate crucial aspects of growth,
development and environmental stress responses. Abiotic stresses, such as drought …

Abiotic stresses increasingly threaten existing ecological and agricultural systems across the
globe. Plant roots perceive these stresses in the soil and adapt their architecture …

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 …
