HEAT SHOCK FACTOR A8a Modulates Flavonoid Synthesis and Drought Tolerance.

abstract：:The development of photochemical activity and carbon assimilation in light-grown cucumber (Cucumis sativus L. cv Natsusairaku) leaves was studied to determine the pattern of acquisition and its relationship to leaf growth and expansion. Measurements of chlorophyll a fluorescence showed that leaves acquire photochemica...
