Research Progress in Waterlogging and Submergence Tolerance of Crops

Stress on crops imposed by soil waterlogging and submergence constitutes one of the major abiotic constraints on growth,distribution of species and agricultural productivity.When crop plants are subjected to soil waterlogging and submer-gence,their root and shoot systems respond differently.A wide range of molecular,physiological,biochemical and morpho-logical adaptations supports the growth and reproductive success of crop plants.This article reviewed recent work on crop re-sponses to waterlogging and submergence stress,which addressed the questions that how root tips were killed and that how roots and above-ground shoots survived under waterlogging and submergence.The genetic analysis of waterlogging and sub-mergence tolerance was also reviewed.Some suggestions in this field were pointed out.
