e0“Pearl millet, Pennisetum glaucum , is capable of adapting to severely dry environmental conditions”
e7“While it is possible that K + and NO 3 – were the major components contributing to osmotic regulations, sugars and amino acids might also function as a cytoprotectant, in addition to their role as osmoprotectants”

Other claims from this paper (10)
- Intervention effect Leaves of the tolerant accession IP8210 exhibited upright folding under severe drought.
- Intervention effect Leaves of the susceptible accession IP8949 wilted under drought stress.
- Intervention effect Osmotic adjustment capacity was greater in younger leaves and stems of IP8210 than of IP8949 under drought.
- Intervention effect The decrease in relative water content under drought differed between IP8210 and IP8949.
- Intervention effect IP8210 accumulated higher NO3– concentrations than IP8949 under drought stress.
- Observation Sucrose, glucose, quaternary ammonium compounds and amino acids including proline accumulated in pearl millet under drought.
- Intervention effect IP8210 accumulated more amino acids than IP8949 under drought, mainly asparagine and proline.
- Intervention effect IP8949 accumulated more soluble sugars than IP8210 under drought.
- Mechanism Sugars and amino acids may function as cytoprotectants in pearl millet under drought.
- Mechanism Leaf folding, osmotic adjustment and NO3– and amino acid accumulation contribute to superior drought tolerance of IP8210 in pearl millet.
