Due to highly consumption of extensive wild germplasm of Allium hirtifolium Boiss (Mooseer) in food and medicinal industry, exploration and domestication process have been done in Golestan province (Gorgan). Economic productions of domesticated Persian Shallot plants need to be improved through breeding process. The successes of domesticated accessions improvement program depend on the availabl...

Background: Traditionally, morphological features of Rhipicephalus (Boophilus) annulatus from closely-related ticks have been considered for their identification and differentiation. However, it is difficult and requires expertise in order to accurately identify and differentiate engorged female ticks and some developmental stages such as larva and nymph from other similar ticks. Hence, molecul...

Spinach (Spinacia oleracea L.) is an economically important leafy vegetable crop in many countries. This is the first case study of using SRAP markers to analyze genetic diversity of Iranian spinach accessions. Eight SRAP primer combinations generated 88 scorable bands ranging from 50 to 1000 bp, among which 73 were polymorphic, with an average of 82.9 polymorphic bands per primer combination a...

different species of streptomyces are common in most types of soil. some certain species are plant pathogenic especially on potato. this study was conducted to evaluate genetic diversity among some local streptomyces spp. strains isolated from soil and infected tubers in potato farms in northwest of iran. repetitive dna elements (box, eric and rep) as genetic markers were used for diversity stu...

The classification of bamboos based on floral morphology and reproductive characters is very hard due to erratic flowering behavior and unusually long reproductive cycle. The application of reliable and effective DNA molecular markers is highly essential to address this problem. In the present investigation, inter-simple sequence repeats (ISSR) markers were employed to study phylogenetic relati...

salinity is one of the important problems in the world's agricultural land that each year millions tons of salt from the soil through crop irrigation arrive to arable lands. wheat is one of the first and most important cereal crops in the world that provide staple food for more than a third of the world's population. using modern genetic methods such as sequencing provided quickly and...

walnut is an important nut crop worldwide. iran is one of the walnut centers of diversity and cultivation. morphological traits and rapd primers were applied to determine genetic diversity among 31 iranian and four foreign walnut genotypes. from 14 rapd primers, 180 bands were amplified among which 174 were polymorphic. the lowest and highest similarity coefficients were 0.37 and 0.89 respectiv...
