BACKGROUND Coccidioides immitis and C. posadasii cause coccidioidomycosis, a disease that is endemic to North and South America, but for Central America, the incidence of coccidioidomycosis has not been clearly established. Several studies suggest genetic variability in these fungi; however, little definitive information has been discovered about the variability of Coccidioides fungi in Mexico ...

The common snook is one of the most abundant and economically important species in Usumacinta basin Gulf Mexico, which has led to overfishing, threatening their populations. main goal present study was assess genetic diversity structure along River order understand population dynamics conservation status species. We characterized two mitochondrial markers (mtCox1 mtCytb) 11 microsatellites basi...

Centaurea amaena is an endemic and endangered species listed as CR (critically endangered) in Turkey. ISSR markers were used to detect the level of genetic diversity two natural populations C. amaena. A total 50 primers 13 producing polymorphic reproducible products selected. These yielded 102 amplified discernible loci, which 80 (78%) polymorphic. high was detected both at population levels; e...

Wuyi Mountain in Southeast China is the origin of black tea and oolong tea. It also considered ‘treasure trove cultivars’ because its rich germplasm resources. In present study, population structure genetic diversity 137 germplasms from adjacent areas were analyzed by SNPs. The information index (I), observed heterozygosity (Ho), expected (He) fixation (F) polymorphisms selected SNPs high, stab...

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...

Here, we investigated the population genetic structure and diversity of endemic Chinese oceanic sipuncula Phascolosoma esculenta by using partial mitochondrial DNA 16S rRNA sequences. In total, 80 samples were collected from Xiangshan, Wenling, Ningde, Zhanjiang, which are four muddy intertidal zones southeastern China. Results showed that gene fragments, 5 1010 bp in length, 73 1011 2 1012 len...

Abstract The Northeastern Mata Atlântica freshwater ecoregion (NMAF) is recognized for the high degree of endemism its ichthyofauna, whose evolutionary and biogeographic histories are still poorly understood. Oligosarcus acutirostris a fish species endemic to NMAF, which distributed in coastal rivers streams draining Bahia, Espírito Santo, part Minas Gerais states eastern Brazil. Its widespread...

Citrus tristeza virus (CTV) is an important citrus pathogen causing considerable economic loss to production. Knowledge on genetic evolutionary of the CTV population in China remains limited. In this study, 1439 samples were collected from nine citrus-producing areas China. The coat protein (CP) genes amplified by RT-PCR, and sequenced analyze evolution. Analysis base composition showed AU pref...

Indo-Burmese region was the primary center of eggplant diversity from where crop extended to several secondary origins diversity. In this study, genetic among fifty-six accessions collected three countries assessed using sixteen polymorphic SSR markers determine suitable parents for heterotic hybridization. The estimation population (Bangladesh, Malaysia, and Thailand) varied 0.57 0.74, with Sh...

the genetic diversity among 56 almond (prunus dulcis) genotypes was analysed using 35 microsatellite markers and 14 morphological traits. analysis of morphological traits revealed a wide range of variation among the studied genotypes. out of 35 simple sequence repeats (ssrs) markers, 25 were polymorphic, producing 215 alleles that varied from 2 to 16 with an average of 8.76 alleles per locus. r...
