Scientists Identify Molecular Conductors that Help Plants Respond to Drought
November 9, 2016| |
A new study conducted at the Salk Institute found molecular conductors that help plants respond to stress such as drought and salinity. The study suggests that during environmental stresses, a small group of proteins acts as conductors to manage the complex responses of plants to stress.
One of these conductors is abscisic acid (ABA), a plant hormone involved in seed development and water optimization. The team exposed 3-day-old seedlings of Arabidopsis thaliana to ABA and checked gene expression at regular time points over 60 hours. Results gathered 122 datasets which involve 33,602 genes, 3,061 of which were expressed at differing levels for at least one time point. Data revealed a hierarchy of control, with some regulatory proteins ranking as top contributors to gene expression.
