How do plant roots grow in unpredictable temperatures? - Salk Institute for Biological Studies
Highlights Salk scientists find a plant protein that can directly sense temperature, giving plants a built-in cellular “thermostat” The study reveals that temperature changes both the amount and activity of key auxin-related growth proteins by shifting a stored “reservoir” of inactive proteins into an active state Findings could enable new strategies to help crops maintain growth under environmental stressors LA JOLLA—Plants can’t move to escape the heat like humans can—they are forced to adapt. As temperatures fluctuate, one key survival strategy is the ability of roots to keep growing, allowing plants to access water and nutrients further away in the soil. But how do plants sense temperature and translate it into growth?
