This laboratory studies the environmental plant physiology of important San Joaquin Valley crops, particularly as ozone air pollution interacts as an additional abiotic stressor. We investigate the mechanistic basis of ozone toxicity to photosynthesis, gas exchange, root function and carbohydrate allocation in individual plants, and methods to scale these impacts to canopies and communities of plants. Measurements are made at levels of biological organization ranging from isolated tissue, to individual organs and plants, to extensive canopies in the field. An important mission is providing timely information on ozone impacts to agricultural producers and to the regulatory community at local and national levels.
