Analysis of protein diversity among five different varieties of Rosa species through SDS-PAGE

The work was done to analyze the relationship between five different varieties of Rosa indica belonging to the family Rosaceae collected from Tirunelveli District of Tamilnadu. The five varieties of rose were characterized by analyzing protein variability in leaf tissues through SDS PAGE. The electrophorogram showed a total of 54 bands of proteins with molecular weight ranging from 4.6 KDa to 152.5 KDa. The protein diversity analysis was conducted on the basis of presence or absence of bands and interpreted using NTSYS software; their molecular weights were also calculated. The protein variability analysis clearly showed that there was divergence among these varieties of rose.
