Sugarcane breakage, through better antioxidant capacity as compared to

                         Sugarcane (Saccharum species hybrids) is a lengthy or time
taking and required excess of water for this cash crop to cultivate under
varied agro-ecological environment. Moreover experiencing different weather
environment all the year round, alteration in climate, the range of the day,
further ecological condition cause the development of sugarcane by distressing
the abiotic stresses, growth of sugarcane, sugar production, its growth and
revitalization, ratooning capability and accessibility of sugarcane seed for
successive planting. The comparatively more litheness of sugarcane towards
abiotic stresses appears due to some native changing as a good array of
compensatory potential, C4 photosynthesis, require privileged
temperature for the majority of the physiological behavior (but for sugar
increase). Besides, a number of the genetic or physiological interventions as
providing the drought hardiness, helping of roots to penetrate deeply in soil,
heat load can be condensed by litter mulching, increasing the age of the crop
at the beginning of dearth/floods, by amendmenet of organic matter in soil,
improvement in nutrients and managing the rhizospheric
salinity/alkalinity, etc., also improve to stress tolerance in sugarcane. Moreover,
there are number of genes, miRNAs
techniques and different molecular markers are associated to control these stress
responses which contribute to buoyancy of sugarcane towards abiotic stresses.
Such efforts will lead to development of a stress resistance variety of
sugarcane utilizing NHX gene, imparting salt tolerance
esapcially Na+/K+, for commercial cultivation.

 Seed performance can
be improved by seed priming a well known pre-germination strategy. However,
biochemical and molecular mechanisms underlying priming mediated stress
tolerance are little understood. Here, I’ll report results of the study on
growth, physiological characteristics, the growth pattern and expression of
stress reactive genes in salt primed. The antioxidant capacity, osmolytic
improvement and unpredictable growth were exposed between the primed and
non-primed plants. The prepared plants showed better forbearance towards the
salt or PEG stress, as showed by better development and lower membrane breakage,
through better antioxidant capacity as compared to the respective non-primed
controls. Further, steady state transcript expression analysis revealed up regulation
of sodium-proton-antiporter (NHX),
while down-regulation of sucrosetransporter (SUT1), delta1-pyrolline-5-carboxylate-synthetase (P5CS) and proline-dehydrogenase (PDH) in primed plants on exposure to the
stress as compared to the non-primed plants. By altering gene expression the
results showed that primed mediated salts and PEG stress tolerance have improved
the antioxidant capacity in sugarcane.
