Mitochondrial genome variations have been detected despite the overall conservation of this gene content, which has been valuable for plant population genetics and evolutionary studies. Here, we describe mitochondrial variation architecture and our performance of a phylogenetic dissection of Korean landrace and weedy rice. A total of 4,717 variations across the mitochondrial genome were identif...

genetic diversity of six populations of bartail flathead (platycephalus indicus linnaeus, 1758) was investigated using amplified fragment length polymorphism (aflp). a total of 118 reproducible bands amplified with ten aflp primer combinations were obtained from 42 fishes that were collected from six different locations in the northern part of the persian gulf. the percentage of polymorphic ban...

The virulence pattern of the isolates of Pyricularia grisea from commercial fields of the upland rice (Oryza sativa) cultivars ‘Primavera’ and ‘BRS Bonança’ was analyzed. A hundred and seventy monoconidial isolates of the pathogen virulent to ‘Primavera’ and 139 to ‘BRS Bonança’ collected from eight fields, during two years (2001-2003) were tested, under greenhouse conditions, on six newly rele...

results all 90 campylobacter isolates confirmed by m-pcr were successfully typed using flaa-pcr-rflp. eleven different types were defined according to flaa-typing method and the rflp patterns were located at three separate clusters in rflp image analysis dendrogram. conclusions campylobacter jejuni isolates significantly showed more variety than c. coli isolates. a relatively low genetic divers...

the genetic variation and population structure of narrow-clawed crayfish (astacus leptodactylus) was examined by means of polymerase chain reaction (pcr) restriction fragment length polymorphism (rflp) analysis of the cytochrome oxidase subunit i (coi) of mitochondrial dna. a total of 194 adult specimens were collected from seven sample sites including, two in the south caspian sea and one each...

anthracnose caused by colletotrichum gloeosporioides s. l. is one of the most important diseases of citrus in northern iran. to study the genetic structure of c. gloeosporioides s. l. from citrusspp., infected samples were collected from three citrus cultivating regions of northern iran, during the summer of 2009. fifty one monoconidial isolates were used as the objective of rep- and box-pcr fi...

This study was carried out to investigate the genetic diversity and population structure of 90 specimens of Oxynoemacheilus argyrogramma collected from Sepidbarg, Gamasiab and Ghaleji rivers, in the west of Iran. Analyses using three microsatellite loci indicated that the average number of alleles in the population was 12, which was well above the reported values for freshwater fishes. The expe...

In order to understand the pathogen’s genetic diversity and dynamics of fungal populations, 34 rice blast isolates collected from various blast endemic areas of India were analyzed using Magnaporthe grisea genome specific microsatellite markers (MGM) and repeat element based Pot2 primer. All the blast isolates showed average pair wise similarities in the range of 0.15 to 0.9 and suggested the l...
