Abstract:
Peanuts ( Arachis hypogaea), also called ground nut are world’s vital oil producing crop.
They are consumed all over the world due their high nutritional value. Peanuts contain
many compounds like proteins, fibers, polyphenols, antioxidants, vitamins and minerals.
In recent times, peanuts are getting higher attention due to their containment of resveratrol
and stilbenoids in the kernels and other parts of plant. Stilbenes and stilbenoids are a well known class of naturally occurring small group of phenylpropanoids which have been
identified in at least 72 unrelated plant species. These compounds are stress metabolites
produced in leaves and other parts of the plant in response to various biotic and abiotic
stresses stresses such as infection, wounding, UV-C exposure and treatment with
chemicals. In this study, Structural and functional analysis of stilbenes synthase gene (s)
was performed through In-silico analysis. In addition, Real Time PCR evaluated the
expression of putative gene upon hormonal treatment in two registered varieties (Golden
and BARD) of peanut plant. Differential expression was observed in both the varieties.
However, Pattern of expression of putative genes was observed to be different between
both the varieties (Inter-Varietal differential expression). The anaylsis showed that
hormonal treatment evidently triggers Stilbenes production in Arachis hypogaea.
