There is a lack of information on the molecular characterization of Ocimum species and hence, efforts have been made under the present study to characterize 17 Ocimum genotypes belonging to 5 different species (O. basilicum, O. americanum, O. sanctum, O. gratissimum and O. Polystachyon) through random amplified polymorphic DNA (RAPD) and inter simple sequence repeats (ISSR) markers. PCR amplifi...

Karnal bunt of wheat, caused by Tilletia indica Mitra is an important disease prevalent in several countries. The pathogen due to its heterothallic nature shows high variability. In the present study, genetic relationships among ten isolates of T.indica collected from different locations of India and 15 monosporidial lines raised from these isolates were investigated by using 34 RAPD and 28 ISS...

Chlorophytum borivilianum is a traditional medicinal plant distributed throughout the trop‐ ics and subtropics. In the present investigation, RAPD and ISSR analyses were used to assess the genetic diversity among 21 accessions collected from different geographical regions of India using 20 RAPD primers and 6 ISSR primers. RAPD and ISSR primers revealed 92.26% and 82.76% polymorphism, respective...

Mungbean improvement via hybridization requires the identification of true F(1) hybrids from controlled crosses before further generations of selfing/crossing and selection. We utilized inter-simple sequence repeat (ISSR) markers for identifying putative F(1) hybrids from six cross combinations whose morphological characteristics were very similar to those of their respective female paren...

Inter-simple sequence repeat (ISSR) analysis was used to develop fish species-specific molecular markers for four Tilapia species (Oreochromis niloticus, Oreochromis aureus, Tilapia zillii and Sarotherodon galilaeus). 12 ISSR primers were tested to assess the effectiveness of ISSR analysis in discriminating among the four applied fish species. Some ISSR markers were detected as species-specific...

Genetic and epigenetic changes (DNA methylation) in the mother plants of somatic hybrids (1st cycle) and their regenerants (30th cycles sub-cultured) were analyzed using methylation-sensitive ISSR and RAPD markers. ISSR and RAPD profiles and their cluster analyses based on the Jaccard’s similarity coefficient revealed 100% genetic similarity among the mother plant and their regenerants. While f...

BACKGROUND Gymnema sylvestre, a vulnerable plant species, is mentioned in Indian Pharmacopeia as an antidiabetic drug. OBJECTIVE Study of genetic and chemical diversity and its implications in accessions of G. sylvestre. MATERIALS AND METHODS Fourteen accessions of G. sylvestre collected from Central India and assessment of their genetic and chemical diversity were carried out using ISSR (i...

Wild olive (O. europaea ssp cuspidata) plants grow in various regions of Iran and are expected to have considerable genetic diversity due to adaptation to the various environmental conditions. We examined the genetic diversity of four populations of wild olive growing in Hormozgan Province located in southern Iran by using 30 RAPDs and 10 ISSR markers. The mean value of polymorphism for RA...
