Characterization of chilling-shock responses in four genotypes ofMiscanthus reveals the superior tolerance ofM. × giganteus compared withM. sinensis and M.sacchariflorus

摘要

Background and AimsThe bioenergy grass Miscanthus is native to eastern Asia. As Miscanthus uses C4 photosynthesis, the cooler temperatures experienced in much of northern Europe are expected to limit productivity. Identification of genetic diversity in chilling tolerance will enable breeders to generate more productive varieties for these cooler regions. Characterizing the temporal relationships between photosynthesis, carbohydrate and molecular expression of relevant genes is key to understanding genotypic differences in tolerance or sensitivity.
