How do millets respond to abiotic stresses such as drought, heat, and salinity at the physiological level, and what mechanisms are involved in their adaptation to these stresses?
How do millets regulate their photosynthesis, water use efficiency, and nutrient uptake under such conditions?
What are the key traits that contribute to their resilience to abiotic stresses?
Comparative abiotic research between millets and other crops can be beneficial if plant mechanisms can be determined, then improved and bred into each crop. To understand stress factors, millets' genetic diversity should be part of any abiotic stress study before breeder selections are determined and replicated.
