In this presentation, I would like to provide the Resistance Mechanism and Molecular Responses to the Salinity. There are two types of plants Halophytes and Glycophytes (categories on the basis of their responses to the salinity) examples are Thellungiella halophila and Arabidopsis thaliana, respectively. Earlier Arabidopsis was considered as Model organism incase of plants but it can't tolerate high saline condition that's the reason for the limited study of plant towards salinity responses. But in the year 2004 the discovery of new plant Thellungiella halophila generates new knowledge about the tolerance mechanism of plants towards salinity responses because it's a halophytes which can tolerate extreme saline condition. And also it has very similarity with the Arabidopsis so it's considered as the Model organism for the study of Salt stress physiology. There are major two pathways involved in response to Salt stress (described in presentation).
