Physiological and Molecular Bases of Drought and Heat Tolerance in Pearl Millet
摘要
Pearl millet is one of the most important sources of nutrition for millions of people in arid and semi-arid areas in Africa and Asia. Farmers have had, throughout its domestication, to select cultivars adapted to their environments. So, pearl millet appears as an interesting crop model to study drought adaptation. However, current and future climatic changes pose challenges to its cropping sustainability. Drought and heat are the main factors of climate change. To accelerate pearl millet adaptation and improve its productivity to cope with climate change, its mechanisms of adaptation must be dissected. Here, we review the state of research on the physiological and molecular bases of pearl millet adaptation to drought and heat. However, pearl millet remains a neglected crop, and progress in research remains to be made.
