e0“Pearl millet, Pennisetum glaucum , is capable of adapting to severely dry environmental conditions”
e1“When these selected accessions were stressed with a severe drought treatment, the leaves of IP8210 exhibited upright folding, a response that effectively reduces the evaporative surface area of the canopy”
e6“IP8210 tended to accumulate more amino acids, typically due to the accumulation of asparagine and proline, while IP8949 accumulated more soluble sugars”

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 IP8949 accumulated more soluble sugars than IP8210 under drought.
- Mechanism K+ and NO3– may be the major components contributing to osmotic regulation in pearl millet.
- 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.
