Abstract

Omeprazole (OP) has been shown to act as a plant growth regulator and enhances tolerance to salt stress. In this study, two Ocimum basilicum genotypes were tested for their responses to OP under salt stress. The two genotypes, Napoletano (NAP) a salt sensitive genotype, and Genovese (GEN) a salt tolerant genotype, had contrasting responses to OP treatment. NAP demonstrated increases in terms of growth (+36%) and salt tolerance (+19%) upon treatment while GEN had a growth increase (+35%) and OP enhanced sensitivity to salt stress (−13%). OP treatment also had an effect on the post-harvest behaviour of these two genotypes by increasing NAP shelf life while decreasing GEN shelf life. The contrasting responses to OP in these two genotypes has provided insight into the role of this molecule in mediating growth and adaptation to stress and, more importantly, into the complexity of the mechanisms mediating these processes.
