Soil and Environment

Project Description

Soil condition of high concentrations of soluble salts is called as salinity. The exposure of plant to salinity is termed as salt stress. In arid and semi-arid regions, the salt stress has become a major abiotic stress because of limited rainfall and high evapotranspiration owing to high temperatures. Maize is one of the most important cereal crops of the world. It is considered as salt-sensitive glycophyte plant and exposure to NaCl causes reduction in the shoot and primary root growth significantly. Interestingly, studies have revealed that it was not the turgor or osmotic adjustment which hampered the plant growth in first phase rather the extensibility of the cell wall which inhibited the plant growth. Cell wall is considered to be the main control point for the cell elongation and is affected from the salt stress conditions. Recent studies have shown that in addition to apoplastic pH, some cell wall proteins like expansins (EXP), xyloglucan endotransglucosylase (XET) etc. are also involved in cell wall elongatgion. Histone acetylation associated up-regulation of ZmEXPB2 and ZmXET1 genes under salt stress condition have been recently observed. As histone acetylation and DNA methylation are linked, we aim to identify DNA methylation profile of the promoter regions of cell wall related genes under salt stress conditions in this proposed study.
