Evaluation of genetic diversity in five species of Ocimum by SDSPAGE

Published on

In India Ocimum (family : Lamiaceae; commonly known
as basil and rich source of essential oil) is represented
by only 6 species [1] and the species are classified into
two broad groups viz., Basilicum and Sanctum on the
basis of morphological and cytological characters [2].
However, standard morphological markers may not
always be adequate because of the wide spectrum of
phenotypic variation and their interaction with
environment [3]. Further, interspecific hybridization and
polyploidy, common occurrences within the genus, have
created taxonomic confusion for proper identification of
the species [4]. In such instances electrophoretic
banding patterns of seed protein can be used effectively
to decipher interrelationships between genotypes [5].
SDS-PAGE of seed protein has also been successfully
used to assess the genetic diversity [6], breeding
endeavour [7] and hybrid identification [8]. In the present
study, five species of Ocimum were characterized using
seed protein polymorphism derived from electrophoretic
banding patterns.
