Molecular modeling and in Silico characterization of a pathogenesis-related protein-10 (PR10)‎ and its coding genes in some Oryza species

الملخص EN

Rice is a major staple food for more than two thirds of the world population.

Pathogenesis-related proteins-10 (PR10) have a range of 154 to 163 amino acid with molecular weight ~ 17 kDa.

They are acidic and generally intracellular and cytosolic proteins accumulate in plants in response to biotic and abiotic stresses.

In the present study, a PR10 gene and its corresponding protein were characterized in O.

sativa, O.

barthii, O.

glaberrima, O.

glumipatula, O.

meridionalis, O.

nivara, O.

rufipogon and O.

punctata.

The results revealed a narrow range of variation at both DNA and protein levels in all examined species except O.

glumipatula.

The latter showed a relatively obvious structural variation at protein level.

Such variation may be beneficial against different types of stress that requires further elucidation to exploit in rice breeding programs.
