alder (alnus subcordata subsp. subcordata) is one of the most important tree species in northern forests of iran and is economically considered as the fourth commercial tree. a leaf spot disease of alder caused by xanthomonas sp. has been reported from several forest regions of mazandaran province (rahimian et al. 1383. 16th iran. plant protec. cong., 439). according to a recent genomic study, ...

Populations of the temperate seagrass, Zostera marina L. (eelgrass), often exist as discontinuous beds in estuaries, harbors, and bays where they can reproduce sexually or vegetatively through clonal propagation. We examined the genetic structure of three geographically and morphologically distinct populations from central California (Elkhorn Slough, Tomales Bay, and Del Monte Beach), using mul...

background: masske is a traditional iranian butter made from yoghurt. the first aim of this study was to isolate and identify the nonlactic pathogenic microflora by culture and molecular methods of identification, and the second purpose was to identify genetic similarity of the isolated bacteria in masske. materials and methods: in order to detect pathogenic dominant indicator microorganisms, a...

background: re-emergence of pertussis has been reported in iran despite a high rate of vaccination coverage. low efficacy of the vaccine might be due to the genetic divergence between clinical versus vaccine strains. in the current study, the genetic profiles of clinical isolates and vaccine strains of bordetella pertussis (b. pertussis) were assessed by using pulsed field gel electrophoresis (...

introduction: the early blight of tomato caused by alternaria alternata is one of the most important and destructive diseases in khuzestan province. study genetic structure of a. alternata populations provides different levels of information in the management of early blight disease in tomato farms. short sequence repeat (ssr) markers were used to determine the genetic structure and estimate ge...

Cornelian cherry (Cornus mas L.), considered as the ancestor of cultivated trees in Arasbaran region, is a medicinally and economically plant species. However, little is known about genetic diversity, breeding programs, and population structure of this species in mentioned region. Keeping this in view, the main objectives of present study were to analysis the genetic diversity, phyloge...

rapd markers through an application of 23 decamer primers were employed for genetic diversity analysis of some sweet cherry cultivars. bands with good resolution and high repeatability were selected for evaluations. the 23 primers produced 188 bands, among which, 153 were polymorphic. cluster analysis of the cultivars was performed based on the presence (1) and absence (0) of the bands, using j...

japanese plum (prunus salicina lindl.) having originated from china, is now one of the important fruit trees in many countries in the world. knowledge of genetic diversity among existing germplasms provides the possibility of parental selection in breeding improvement programs. for assessment of genetic diversity and relationship among genotypes in iran (ramsar, velyan karaj and mashhad) and fo...

background: garlic is a valuable medicinal plant with variability in desirable morphological and physiological characteristics. the analysis of genetic diversity plays an important role in breeding programs. the rapd technique could be very effective in detecting genetic variation in garlic.  objective: the objective of the present work was to detect molecular polymorphism among iranian garlic ...
