should be studied. Plants such as tomato or pepper are of great interest because they
are mainly cultivated in greenhouses where the levels of CO 2 could be adjusted. The
identification of molecular biomarkers for the salinity stress in plants could help
monitoring the progress of its negative effect on the plant growth and yield of salt-
stressed plants. The latter can further our understanding of the underlying molecular
mechanisms and assist us in devising methods for the educated use of elevated CO 2
conditions to alleviate the salinity impact, supporting plant cultivation processes of
consistent quality and yield.
