Salt stress has a huge impact on the growth of the plant and thus limits large areas of the world from being arable. So a study about the impact of salt stress will enable one to understand how salt stress affects the plants. Further, this study also examined the interaction of other hormones with ethylene, which is a key gaseous stress hormone, in relation to salt stress. This information can aide in the development of genetically engineered salt resistant crops.
However, the conclusions drawn in this experiment cannot be taken for granted
because the exact response of the hormone caused by salt stress cannot be
understood by simply examining the results from plant mutants; however,
it can be used to suggest ideas about the relationships that exist between
ethylene and the other hormones.
To make this a more relevant study, one would have to measure the concentrations
of all the hormones in the plant mutants. This would enable one to begin
making the large number of interlinking connections between the interactions
of the hormones. Other studies that can be performed to further knowledge
include using a larger variety of plant mutants. The experiment should be
repeated for ABA overproducing, auxin overproducing, cytokinins and gibberellin
mutants because these mutants were not considered in this study.
Halophytes or wild plants that grow under salt stress can be examined to
understand the hormonal interactions occurring in these plants and then
that can be attempted to be mimicked in a lab to create salt resistant plants.
