| Summary: | >Magister Scientiae - MSc === In agriculture crop productivity is greatly affected by stresses such as salinity, drought,
temperature and honnonal changes of crop plants and responses to these stresses. Studies
have shown that a natriuretic peptide based regulatory system responsible for water and ion
homeostasis in animals has a hctcrologous equivalent in plants. Plant natriuretic peptide
immunoreactants (irPNPs) have been reported to be involved in K+, Na+ and er ions fluxes
in plants. Previously, an Arabidopsis thaliana transcript (AtPNP-A) encoding an irPNP
(AtPNP-A) has been identified and isolated (Ludidi et al., 2002). The AtPNP-A a novel
protein and part of its physiological role is presented here.
