Uncovering secrets of plants: how plants ‘know’ their surroundings and ‘think up’ ways to cope with them
|
Being sessile, plants must adapt to all environmental changes or perish. Plants are already well-known to recognize environmental fluctuations and to respond promptly to such changes. Nevertheless, it remains unclear how plants dissect and integrate environmental signals and make a decision to render an optimal response even with no information-integration systems such as those of our central nervous system. To address this question, our group investigates environmental stress response systems of plants using physiological, molecular biological, and molecular genetic approaches. Among stress responses, we emphasize the study of stress-associated plant hormone signaling. Our ultimate goal is to take advantage of the research outcomes to create stress-tolerant crops.
