摘要

The plant applies ion exclusion and tissue tolerance mechanisms for Na+ management under salinity stress. Different families of transporters/antiporters belonging to SOS1, HKT, and NHX families played key role in ion exclusion and tissue tolerance. In grass species, salt stress induces anatomical adaptations such as cortical senescence/aerenchyma formation, which creates extra spaces and plays an important role in ion exclusion. Based on reports, in stem, and leaf sheath, aerenchyma formation provides some additional spaces for dumping of Na+ and Cl− ions. The study by Hameed et al. (Plant Soil 322:229–238, 2009; Acta Physiol Plant 33:1399–1409, 2011) has highlighted the essence of aerenchyma formation in root, stem, and leaf for grass species such as Imperata cylindrica, and Sporobolus arabicus under salt stress. Recent studies by Wasim and Naz (JAPS: J Anim Plant Sci, 2020) and Wasim et al. (S Afr J Bot 144:471–479, 2022) showed a significant rise in root aerenchyma at moderate salinity (100 mM) for Cenchrus ciliaris. These findings provide an alternative for Na+ and Cl− ion management in grasses that help to survive under adverse environmental conditions.
