The time of the day to harvest affects the degreening, antioxidant compounds, and protein content during postharvest storage of broccoli.

Harvesting of broccoli at several moments of the day affects the rate of senescence during storage. In this work, broccoli heads were harvested at several moments and then kept at 20°C in order to analyze protein metabolism and antioxidant compounds. Almost no differences were detected in the contents of total and soluble proteins, and free amino acids.

Up-regulation of the mitochondrial alternative oxidase pathway enhances photosynthetic electron transport under drought conditions.

The aim of this study was to explore the role of the mitochondrial alternative oxidase (AOX) in the protection of photosynthesis during drought in wheat leaves. The relative water contents of water-replete and drought-exposed wheat plants were 97.2+/-0.
