Chlorophyll closely related to photosynthetic capacity and developmental stage in crops. In order to reveal the genetic characters of chlorophyll content in leaf above ear, ear leaf and leaf under ear (three-ear-leaves) of maize, ten inbred lines from five different heterotic groups were selected to make crosses by a completely diallel cross design. The combining ability analysis and genetic parameters estimations of chlorophyll content of... Read more

Chemotherapy is a main treatment for cancer, while multidrug-resistance is the main reason for chemotherapy failure, and tumor relapse and metastasis. Cancer stem cells or cancer stem-like cells (CSCs) are a small subset of cancer cells, which may be inherently resistant to the cytotoxic effect of chemotherapy. Some studies suggest that CSCs could be enriched by chemotherapy. However, the mechanism of chemotherapy regulating CSCs remains unknown.... Read more
