Plants adapt to drought stress by reshaping their root architecture, a process in which abscisic acid signalling plays a key role. A recent study defines the mechanism by which abscisic acid signalling mediates sucrose transport from shoots to roots, thus modulating root growth under drought stress.
Incorporation of multiple-nucleotide substitution in prime-editing guide RNAs greatly boosts editing efficiency in rice and maize, advancing precise genome editing in plants.
Plant malectin-like receptor kinases (also known as CrRLK1Ls) have functions in plant development such as pollen tube growth and cell wall integrity sensing. This Perspective reviews recent evidence suggesting a critical role of these receptors in plant immunity.
