Understanding the transcriptional network regulating ZmPEPC1 gene expression
| Resumo: | Human population is growing fast and this will lead to an extremely high demand for food, feed, and energy. Therefore, to guarantee future food security, we definitely need to improve crop yield. Given that C4 photosynthesis is much more efficient than C3 photosynthesis, and therefore correlated with higher plant productivity, one strategy to improve crop yield is to transfer C4 photosynthetic traits into C3 crops, such as rice. However, this strategy requires a deep understanding of the transcriptional C4 gene regulation, so far poorly understood. In most C4 plants, the C4 metabolism is associated with a specific leaf anatomy (Kranz anatomy) and compartmentalization of the photosynthetic reactions into two leaf cell types, mesophyll (M) and bundle sheath (BS), which is based on a tightly regulated cell-specific gene expression.(...) |
