fusarium verticillioides (f. verticillioides) is not only a primary pathogen of maize, but also can causedisease in other crops such as sorghum. pathogenicity is related to mycotoxin production such as fumonisin.in the present study, 24 isolates of f. verticillioides, which were previously identified by phenotype basedmethods, were re-identified using restriction fragment length polymorphism (r...

Crataegus spp. are used for horticultural and medicinal purposes. The medicinal importance of Crataegus is attributed to components such as flavonoids, procyanidin, aromatic acid, and cardiotonic amines. The genetic relationships among the five Iranian Crataegus species including C. aronia, C. pontica, C. meiery, C. monogyna, and C. pentagyna were assessed using inter simple sequence repeats (IS...

in this study, srap molecular maker approach was performed to investigate genetic diversity in the salvia genus. a total of 205 dna bands were produced from pcr amplification of 11 salvia species and populations using 25 selective primer combinations, of which 204 polymorphic genetic loci accounted. the total number of amplified fragments ranged from 3 to 15. the genetic similarities of 11 coll...

almond is one of the most valuable horticultural nut crops in the world with iran being amongst the most important regions of its distribution. rapd markers were employed to evaluate the diversity levels and relationship among some 56 collected genotypes of the crop. through sixteen rapd primers a number of, 171 dna bands were produced, 168 of which were polymorphic. the samples which according...

Effects of induced mutation via gamma irradiated with 250 Gy dose (in Nuclear Agriculture Research School- Nuclear Science and Technology Research Institute) on Trichoderma harzianum conidiaon chitinase activity by STS molecular marker have been evaluated in this study. Among 20 irradiated mutants which selected via improved antagonistic capability against Rhizoctonia sola...

Dog Rose is one of the most important species in Rosaceae family used as a medicinal plant and a rootstock for ornamental roses. This species is native to Iran, therefore, identification of indigenous genotypes of this species is important for genetic preservation or breeding purposes. Genetic diversity estimation of plant materials is one of the important pre-breeding activities in breeding cr...
