Curraleiro Pé-Duro is a rustic bovine taurine breed found in Northeast of Brazil; this breed has decreased its production potentially in order to adapt to the region environment conditions. Consequently, it is under risk of extinction and is maintained at a preservation center in Piauí State, Brazil, as a source of genetic material adapted to local conditions. We analyzed genetic ... more
The genetic diversity of 51 upland cotton cultivars with different parental origins and breeding periods that were developed in Hubei Province was studied on the basis of 237 mapped simple sequence repeat markers covering the cotton genome. A total of 108 polymorphic primer pairs amplified 196 loci; the polymorphism information content range was 0.04 to 0.83, with an average of 0.46. A ... more
The genetic diversity and relationship of 42 tomato varieties sourced from different geographic regions was examined with EST-SSR markers. The genetic diversity was between 0.18 and 0.77, with a mean of 0.49; the polymorphic information content ranged from 0.17 to 0.74, with a mean of 0.45. This indicates a fairly high degree of diversity among these tomato varieties. Based on the ... more
The purpose of this study was to analyze the effects of management on the genetic structure of natural populations of Attalea speciosa in the State of Piauí, Brazil, using random-amplified polymorphic DNA (RAPD) markers. Three babassu populations under different management systems were selected. Polymerase chain reactions were performed for 20 RAPD primers. A total of 146 bands ... more
Fengshui forests (sacred groves) are important in traditional Chinese culture and home to many endangered species. These forests may provide protection for some endangered plant species outside the nature reserves, but little is known about their role in genetic conservation. Using inter-simple sequence repeat (ISSR) markers, we compared the genetic diversity of 6 populations of ... more
Persimmon (Diospyros L.) is an economically important fruit in the world, and it has been recognized as a healthy nutrient supply for human consumption. In this study, 14 microsatellite markers were developed from an AG/TC and AC/TG-enriched genomic library of Chinese persimmon Mopanshi. Twelve polymorphic markers were selected in 4 related species; these markers showed ... more
Cotton is an important cash crop. Mining for quantitative trait loci related to yield and fiber quality traits using association analysis has many advantages for cotton research. In this study, 170 simple sequence repeats (SSRs) and 258 sequence-related amplified polymorphisms (SRAPs) were used to analyze the association of 3 yield component traits and 5 fiber quality traits of 55 ... more
Current DNA extraction protocols, which require liquid nitrogen, lyophilization and considerable infrastructure in terms of instrumentation, often impede the application of biotechnological tools in less researched crops in laboratories in developing countries. We modified and optimized the existing CTAB method for plant genomic DNA extraction by avoiding liquid nitrogen usage and ... more
Conventional hybridization and selection techniques have aided the development of new ornamental crop cultivars. However, little information is available on the genetic divergence of bromeliad hybrids. In the present study, we investigated the genetic variability in interspecific hybrids of Aechmea gomosepala and A. recurvata var. recurvata using inflorescence ... more
Idesia polycarpa Maxim. is a dioecious species. Because of the lack of morphological and cytological methods available for identifying its sex during the long juvenile stage, the application of molecular markers in sex identification may facilitate sex determination in the seedling stage. The objective of this study was to use sequence-related amplified polymorphism to identify ... more
