Description
Eva Maria Gómez-Álvarez explains how plants use gene splicing to tune their drought response. A plant hormone called ABA tells leaves to close their pores and save water under stress. Too much of that signal, though, stalls growth. Plants need a dial, not just a switch. New work shows one gene's alternate forms act as that dial.
The gene, WRKY55, helps control the ABA signal chain. Cutting its message in different ways yields forms with different effects. Some forms press the stress response forward, others hold it back. That balance lets the plant weigh survival against growth as stress rises and falls. Gómez-Álvarez frames splicing as a timing tool in stress biology. The insight may guide crops bred for a drier climate.
