The circadian clock is an autonomous oscillator that produces endogenous biological rhythms with a period of about 24 h.

In plants, circadian rhythms contribute to both evolutionary fitness and agricultural productivity. Nevertheless, we show that commercial b...

Therefore, the beginning of summer (winter) can be interpreted as the inward movement of summer (winter) monsoons. Considering the important role of mei-yu period, Chen (2000) pointed out that mei-yu should be added as a...
