- Intervention effect Midday photosynthetic rates of dryland cotton plants decreased 2-fold.
- Intervention effect Canopy temperature of dryland cotton rose to 40 degrees C at 80 days after planting, compared with 30 degrees C for irrigated plants.
- Intervention effect Leaves of dryland cotton accumulated stainable polypeptides of 100, 94, 89, 75, 60, 58, 37 and 21 kDa that did not accumulate in irrigated leaves.
- Intervention effect Radiolabeled polypeptides of cotton leaves incubated at 40 degrees C for 3 hours had molecular weights similar to those accumulating in dryland cotton leaves.
- Mechanism The proteins accumulating in water-stressed cotton leaves at elevated temperature are suggested to be heat shock proteins.
- Observation Heat shock proteins can accumulate to substantial levels in field-stressed cotton plants.
