Grain size is a key agronomic trait that determines the yield in plants. Regulation of grain size by brassinosteroids (BRs) in rice has been widely reported. However, the relationship between the BR signaling pathway and grain size still requires further study. Here, we isolated a rice mutant, named small grain2 (sg2), which displayed smaller grain and a semi‐dwarf phenotype. The decreased grain size...
The classic W4 theory is recognized as an importance branch of the moving object detection field because it can simply and effectively describe a background model, calculate the result very quickly. But we find that this theory has two disadvantages: the first is the definition of the stationary pixels, the second is the background updating criterion when some foreground moving object is fused in...
