"Pearl millet [Pennisetum glaucum (L) R. Br.] is an important cereal crop of the semiarid\r\ntropics, which can withstand prolonged drought and heat stress. Considering an active\r\ninvolvement of the aquaporin (AQP) genes in water transport and desiccation tolerance\r\nbesides several basic functions, their potential role in abiotic stress tolerance was\r\nsystematically characterized and functionally validated. A total of 34 AQP genes from\r\nP. glaucum were identified and categorized into four subfamilies, viz., plasma membrane\r\nintrinsic proteins (PIPs), tonoplast intrinsic proteins (TIPs), nodulin-26-like intrinsic\r\nproteins (NIPs), and small basic intrinsic proteins (SIPs). Sequence analysis revealed\r\nthat PgAQPs have conserved characters of AQP genes with a closer relationship\r\nto sorghum. The PgAQPs were expressed differentially under high vapor pressure\r\ndeficit (VPD) and progressive drought stresses where the PgPIP2;6 gene showed\r\nsignificant expression under high VPD and drought stress. Transgenic tobacco plants\r\nwere developed by heterologous expression of the PgPIP2;6 gene and functionally\r\ncharacterized under different abiotic stresses to further unravel their role. Transgenic\r\ntobacco plants in the T2 generations displayed restricted transpiration and low root\r\nexudation rates in low- and high-VPD conditions. Under progressive drought stress,\r\nwild-type (WT) plants showed a quick or faster decline of soil moisture than transgenics.\r\nWhile under heat stress, PgPIP2;6 transgenics showed better adaptation to heat\r\n(40C) with high canopy temperature depression (CTD) and low transpiration; under\r\nlow-temperature stress, they displayed lower transpiration than their non-transgenic\r\ncounterparts. Cumulatively, lower transpiration rate (Tr), low root exudation rate, declined\r\ntranspiration, elevated CTD, and lower transpiration indicate that PgPIP2;6 plays a role\r\nunder abiotic stress tolerance. Since the PgPIP2;6 transgenic plants exhibited better\r\nadaptation against major abiotic stresses such as drought, high VPD, heat, and cold\r\nstresses by virtue of enhanced transpiration efficiency, it has the potential to engineer\r\nabiotic stress tolerance for sustained growth and productivity of crops."^^ .
