Amplified fragment length polymorphism; Genetic diversity; Jackfruit; Markers; Polymorphism

Artocarpus heterophyllus Lam., commonly called jackfruit, is a medium-sized evergreen tree that bears high yields of the largest known edible fruit. Yet, it has been little explored commercially due to wide variation in fruit quality. The genetic diversity and genetic relatedness of 50 jackfruit accessions were studied using amplified fragment length polymorphism markers. Of 16 primer ... more

Amplified fragment length polymorphism; Colchicum; Maximum parsimony; Neighbor-joining method; Phylogenetic relationship; Principal component analysis

The study of phylogenetic relationships between 14 Colchicum taxa spread throughout Turkey was performed using a fluorescent-based amplified fragment length polymorphism (AFLP) technique. Five primer pair combinations were used in AFLP reactions. The data set was analyzed statistically using the NTSYS 2.1 software, and the neighbor-joining and maximum parsimony methods were ... more

Amplified fragment length polymorphism; Function annotation; Low phosphorus; Maize; tolerance

Soil contains a large amount of phosphorus, but plants cannot absorb most of this phosphorus effectively. Low inorganic phosphorus has been singled out as a major constraint that leads to a perpetually low Zea mays (maize) grain yield. The fundamental approach to solving this problem is to screen new genes of low phosphorous (LP) tolerance. Consequently, the exploration and ... more

Amplified fragment length polymorphism; Bupleurum; Chaihu; Genetic diversity; Phylogenetic analysis; Radix bupleuri

Radix bupleuri (Chaihu), the dried root of the Bupleurum plant, is an important component of traditional Chinese medicine. In this study, we examined the genetic diversity of 11 Bupleurum strains, originating from 7 provinces in China, using amplified fragment length polymorphism analysis. A total of 274 polymorphic bands were obtained using 6 primer ... more

Bulked segregant analysis; Drought tolerance; QTL; SSR markers; Wheat

This study was carried out to evaluate the genetic effect of quantitative trait loci (QTLs) conferring drought tolerance in wheat. A population of 120 F2 individuals from the cross between the drought-tolerant S-78-11 and drought-sensitive Tajan cultivars were analyzed for their segregation under drought stress conditions. The relative water content under drought stress ... more

Amplified fragment length polymorphism; Molecular markers; Olive

We sampled six olive cultivars (Tavli Sati, Sati, Gorvela, Sacakli Otur, Butko, and Otur) from Coruh Valley, located in the northeast part of Turkey, and characterized them using amplified fragment length polymorphism (AFLP) markers. Some morphological and biochemical characteristics are also determined. Six AFLP primer combinations were used for molecular characterization and 66 AFLP markers ... more

Bulked segregant analysis; Neotropical fishes; RAPD; Sex determination

Arapaima gigas (Osteoglossidae) is one of the largest fish species in the Amazon Basin, attaining lengths of over 2.5 m and weights of over 100 kg. Its flesh is prized, and it has great potential for production in aquaculture systems. However, live pirarucu cannot be reliably sexed visually, even after sexual development, since this species does not have clear external sexual ... more

Aphid resistance; Bulked segregant analysis; P746; R_P746; Simple sequence repeat marker; Soybean

Soybean aphid (SA: Aphis glycines Matsumura) is one of the most serious pests of soybean [Glycine max (L.) Merr.] worldwide. A single dominant gene was found to control SA resistance in soybean line P746, which exhibits antibiosis resistance. This study aimed to define the location of the SA resistance gene in P746. A F2:3 mapping population, including 312 ... more

Genetic control; Partial diallel; Phaseolus vulgaris L.; Plant architecture; Quantitative genetics

Knowledge of genetic control of plant architecture in the common bean can help breeders define the most adequate breeding strategy to optimize gains. We examined genetic control of plant architecture in the common bean by means of partial diallel crosses. Fourteen bean lines were crossed under a partial diallel scheme, in which group 1 was composed of 8 erect plant lines and group 2 of 6 ... more

Maize; Nitrogen regime; Plant architecture; QTL

Maize (Zea mays L.) is one of the most important cereal crops worldwide, and increasing the grain yield and biomass has been among the most important goals of maize production. The plant architecture can determine the grain yield and biomass to some extent; however, the genetic basis of the link between the plant architecture and grain yield/biomass is unclear. In this study, an ... more
