Hi, I send you an abstract of one of my academic research publications for your evaluation.
Two loci associated with the salt sensitivity response, named SSR1 and SSR2 QTLs, and four loci
for osmotic sensitivity response, named OSR1–OSR4 QTLs, were mapped. The effects of the SSR1 QTL on
toxic salt sensitivity, and the osmotic contribution of OSR1, were confirmed by heterogeneous inbred families
(HIFs). Whilst the SSR1 QTL had a significant effect under a wide range of NaCl concentrations, the OSR1
QTL was confirmed only under moderate drought stress. Interestingly, OSR1 QTL also showed pleiotropic
effects on biomass accumulation in response to water deficit.
Resuming; the regulation of germination under moderate salt and osmotic stresses involves the action of independent
major loci, revealing the existence of loci specifically associated with the toxic component of salt and not
just its osmotic effect. Furthermore, this work demonstrates that novel loci control germination under osmotic
stress conditions simulating more realistic ecological environments as found by populations of seeds in nature.
