Conservation; Genetic structure; Gossypium mustelinum; Microsatellites; Wild cotton

Gossypium mustelinum is the only cotton species native to Brazil; it is endemic to the semi-arid region of the northeast. The populations are found near perennial and semi-perennial sources of water, such as ponds or pools in intermittent streams. Problems with in situ conservation derive from human interference in its habitat, mainly because of excessive cattle grazing ... more

Conservation; Hybridization; SSR molecular marker; Wild cotton

Cotton has been collected in Brazil for decades for its conservation, evaluation, and the use of its genetic resources. Gossypium mustelinum is an allotetraploid cotton species that only occurs in Brazil, and little is known about its genetic potential for improvement. However, the species is threatened by habitat fragmentation and interspecific hybridization with exotic species of ... more

Genetic diversity; Marker-trait association; Population structure; SSR marker; Waxy and normal maize inbred line

Understanding genetic diversity, population structure, and linkage disequilibrium is a prerequisite for the association mapping of complex traits in a target population. In this study, the genetic diversity and population structure of 40 waxy and 40 normal inbred maize lines were investigated using 10 morphological traits and 200 simple sequence repeat (SSR) markers. Based on a population ... more

Chemical analysis; Marker-trait associations; Sorghum; SSR marker

This study evaluated the chemical and genetic diversity of high-seed-yield sorghum germplasms from Korea, the United States, and South Africa. We identified significant differences in the chemical contents of whole plants at the heading stage in all cultivars, including differences in crude protein, fat, fiber, ash, neutral detergent fiber, acid detergent fiber, mineral, and fatty acid ... more

Amazon; Genetic variability; SSR marker

Forest fragmentation reduces the effective size of natural populations, isolates individuals in the landscape, and, consequently, changes species’ mating systems by increasing the degree of relatedness between individuals and inbreeding. Investigating the impact of habitat degradation on forest fragments helps to assess the genetic and ecological consequences of ... more

Allium species; Chinese chive; SSR marker; Transcriptome; Transferability

Chinese chive (Allium tuberosum Rottler ex Spr.) is an important vegetable crop. However, genetic and breeding studies of the species have been restricted by the lack of simple sequence repeat markers (SSRs). In the present study, a total of 2553 Chinese chive SSRs were developed from the species’ transcriptome, with 626, 643, and 536 of the makers located in ... more

Allium cepa L; Genetic characterization; Heterozygosity; Polymorphism; SSR marker

The five most common cultivars from the genus Allium cepa L. in Bosnia and Herzegovina (BiH) were analysed, focusing on Konjic onion. Seven SSR markers for genetic similarity analysis were used to address the genetic backgrounds. The polymorphic relationship between the SSR markers was analyzed by using Polymorphic Information Content (PIC) and Heterozygosity (H) ... more

Malaysian rice; SSR marker; STS marker; xa gene; Xanthomonas oryzae pv oryzae

Xanthomonas oryzae pv oryzae (Xoo) is a bacterial pathovar that causes a serious bacterial leaf blight disease of rice. This disease poses significant constraint on food security in Asia, as it causes yield loss in rice. There is an urgent need to control bacterial blight disease through resistance cultivars. However, the genetic potential of Malaysian ... more

Abscisic acid; Drought tolerance; Medicago sativa L.; Molybdenum cofactor sulfurase

The stress phytohormone abscisic acid (ABA) plays pivotal roles in plants’ adaptive responses to adverse environments. Molybdenum cofactor sulfurases influence aldehyde oxidase activity and ABA biosynthesis. In this study, we isolated a novel EsMcsu1 gene encoding a molybdenum cofactor sulfurase from Eutrema salsugineum. EsMcus1 transcriptional patterns varied ... more

Cowpea; Drought tolerance; Multivariate analysis; Recurrent selection; Vigna unguiculata

Vigna unguiculata (L.) Walp (cowpea) is a food crop with high nutritional value that is cultivated throughout tropical and subtropical regions of the world. The main constraint on high productivity of cowpea is water deficit, caused by the long periods of drought that occur in these regions. The aim of the present study was to select elite cowpea genotypes with enhanced drought ... more
