Sugarcane (Saccharum species hybrids) is a time taking cropand required excess of water for the growth of this cash crop to grow under diverseagro-ecological environment. Moreover experiencing diverse weather environment overallthe whole year, alteration in climate, variations in the day ranges, moreover theecological environment change the development of sugarcane by fluctuating theabiotic stresses, development of sugarcane, sugar production, its growth and renaissance,ratooning potential and accessibility of sugarcane seed required for betterplantation. The comparatively more litheness of sugarcane towards abioticstresses appears due to some native changing as a good array of compensatorypotential, for the number of the physiological behavior (except for sugarincrease) C4 photosynthesis required tolerable rang temperature.
Besides, majority of the genetic and physiological interventions as providingthe drought hardiness, helping of roots to penetrate deeply in earth, heat loadcan be condensed by litter mulching, developing the age of crops at the beginningof scarcity/floods, by amendment of organic substance in soil, by managing andimproving the rhizospheric salinity/alkalinity and nutrients etc., also developto stress tolerance in sugarcane. however, mess of the genes, miRNAs methodologies anddifferent molecular markers are associated to control the stress responses whichcontribute to buoyancy of sugarcane to abiotic stresses. Such efforts will directto development of a stress resistance variety of sugarcane utilizing NHX gene, imparting salt tolerance insugarcane especially against Na+/K+, for commercialcultivation.
Seed performance canalso be improved by seed priming a well known pre-germination strategy.However, biochemical and molecular mechanisms essential for priming mediatedstress tolerance are little understood. Here, I’ll report results of the studyon growth, physiological characteristics, the growth pattern and expression ofstress reactive genes in salt primed.
The antioxidant capacity, osmolytic perfectionand randomized growth will expose between the primed and non-primed plants. Theprepared plants will showed better forbearance towards the salt or PEG stress,as showed by better development and lower membrane ruptured, during improvedantioxidant capacity as compared to the particular non-primed controls.Further, steady state transcript expression analysis revealed up regulation of sodium-proton-antiporter (NHX), while down-regulationof sucrosetransporter (SUT1), delta1-pyrolline-5-carboxylate-synthetase (P5CS) and proline-dehydrogenase (PDH) in primed plants on exposure to thestress as compared to the non-primed plants. By altering gene expression theresults showed that primed mediated salts and PEG stress tolerance have improvedthe antioxidant capacity in sugarcane.
