Advances in Salt-Tolerance Mechanism of Mangrove

TL;DRAbstract

This article summarized some research progresses of salt tolerance in mangrove species at morphology,physiology and biochemistry,and molecular levels.Mangrove species have salt glands and their leaves become succulent.They avoid heavy salt loads through a combination of selective accumulation of ions,ion compartmentalization,salt excretion and salt exclusion,accumulation or synthesis compatible solutes which are mainly pinitol and mannitol for maintaining osmotic balance,and promotion of antioxidative to scavenge reactive oxygen species.At molecular level,salt-tolerance of mangrove plants is involved in gene expression of key enzymes in biosynthesis of osmotic substances and antioxidative enzymes.
