Discovery of a key gene that enables plants to survive drought

A team of scientists from USA, Canada and Spain identified a gene that enables plants to defend themselves against environmental stresses such as drought, frost or heat.

Plants naturally produce hormones associated with stress climate they experience. These stress hormones, called abscisic acid (ABA), reporting adverse conditions to the cells that adjust the time. If the ABA is known, the receptors of ABA carried by the cells is a very controversial in the field of plant biology. However, this team of researchers has identified the receptor for the hormone ABA. To resolve this problem, older than 20 years, the team used a new approach called "chemical genomics" to activate, through a synthetic chemical: the pyrabactin, a receptor for ABA in plant laboratory model and discover its gene. This discovery should open paths of interest in the crop protection against adverse environmental conditions.
