The chemical composition of the essential oils of five natural populations of P. ovalifolia from central and southwest China and their interpopulation variability were first analyzed by using GC-MS. Twenty-two essential oil compounds were obtained, in which eighteen ones were identified and characterized representing 95%-96% of the oil composition. Three main chemotypes, i.e., the methyl-acetyl...

Information on the genetic identity and interrelationships of different Morus spp. genotypes is essential for their proper conservation and utilization. Hence, the present investigation was undertaken with genetically more reliable DNA markers to study the genetic relationship among eleven selected genotypes of mulberry collected from Japan, India and Italy. Using ten RAPD and ten ISSR primers,...

Plant molecular identity (ID) is used to describe molecular characteristics of plants, which should contain all of the necessary information. Using inter-simple sequence repeat (ISSR) primers, molecular ID can be described in a way that reflects the polymerase chain reaction (PCR) conditions, annealing temperature, and the bands obtained in PCR amplification. A new complete molecular ID system ...

The population structure of Phytophthora capsici among asexual and sexual progenies was analyzed using ISSR. Thirty one parent three populations were assayed for genetic diversity 5 ISSR primers DNA from 120 offspring P. amplified. In total, 71 reproducible fragments obtained, which 100% polymorphic, revealing high polymorphism the isolates. Among them, percentages progeny isolates 100.00 77.46...

Sixty isolates of Pythium aphanidermatum as the causal agent of sugar beet root rot were selected on the basis of their geographical origins, morphological and genetic diversity studies. Pathogenicity test using the Kruskal-Wallis analysis showed significant differences between the pathogenic potential of isolates. Based on the growth rate, isolates were categorized in two groups with low and h...

The pathogenicity of 47 isolates of Sclerotinia sclerotiorum from oilseed rape (Brassica napus L.) in Anhui, China, was tested by detached leaf inoculation using the susceptible rape cultivar Wanyou-14. All isolates were pathogenic to the cultivar and could be grouped into 3 categories based on the lesion length on the leaves tested: weak pathogenicity type, intermediate pathogenicity type, and...

Morphological differences among Korean Allium subgenus Rhizirideum sect. Sacculiferum and some related species are minor, making species delimitation difficult. Inter-simple sequence repeat (ISSR) was employed to assess genetic diversity and relationships. Thirty-four accessions, representing six taxa of A. thunbergii, A. sacculiferum, A. deltoides-fistulosum, A. cyaneum var. cyaneum, A. cyaneu...

castor (ricinus communis l.) is one of the most ancient medicinal oil crops in the world. it has been vastly distributed in different parts of iran. in the present study, the inter simple sequence repeat (issr) markers were used to evaluate the molecular genetic diversity among and within 12 castor accessions collected from 7 regions of iran. totally, 16 issr primers amplified 166 loci, of whic...

Abstract. Yani A, Chasani AR, Daryono BS. 2022. Genetic diversity of eight maize Zea mays L. cultivars from East Nusa Tenggara based on inter simple sequence repeat markers. Biodiversitas 23: 4124-4130. (NTT) is one Indonesia's island that has many local cultivars. However, the existence this corn threatened by presence high-yielding seeds. Therefore, characterization using molecular marker nee...
