Genetic diversity; Microsatellite DNA; Mytilus coruscus; Population structure

Twelve new polymorphic microsatellite loci were developed for the hard-shelled mussel, Mytilus coruscus. In 32 individuals from a wild population of coastal Zhoushan, Zhejiang Province, China, the number of alleles at these loci varied from 3 to 15, with a mean of 5.667. The mean observed and expected heterozygosities were 0.6927 and 0.6591, respectively. Among these polymorphic ... more

Genetic diversity; Jatropha curcas; Selective accuracy; Ward-MLM

The use of efficient breeding methods depends on knowledge of genetic control of traits to be improved. We estimated genetic parameters, selection gain, and genetic diversity in physic nut half-sib families, in order to provide information for breeding programs of this important biofuel species. The progeny test included 20 half-sib families in 4 blocks and 10 plants per plot. The mean ... more

Fifteen new polymorphic microsatellite loci were developed for the cuttlefish Sepiella maindroni. In 32 individuals from a wild population of coastal Ningde, Fujian Province, China, the number of alleles at these loci varied between 2 and 12, with an average of 5.86. The mean observed and expected heterozygosities were 0.6917 and 0.5993, respectively. Among these polymorphic ... more

Chickpea; DNA fingerprinting; Genetic diversity; Hybrids; RAPD markers

The intensity of genetic diversity amongst chickpea genotypes and their crosses is unknown. The current study investigated the genetic diversity of chickpea genotypes and their F1 crosses by using random amplified polymorphic DNA (RAPD) markers. We assessed the variation among six chickpea genotypes and 15 F1 crosses with the RAPD markers. The six parents and their ... more

Bromeliaceae; Conservation; Endemism; Genetic diversity; Vriesea cacuminis

Data about the genetic structure can help to understand the evolutionary process of natural populations as well as to drive strategies of conservation. Vriesea cacuminis, an endemic Brazilian Bromeliad, has been found in 2 areas of Minas Gerais State. One is a legal preservation unit (Ibitipoca State Park) and the other an unprotected area (Serra Negra). The 2 areas belong to the ... more

Apis cerana; Genetic differentiation; Genetic diversity; mtDNA

DNA sequence diversity in the tRNAleu-COII portion of the mitochondrial genome was investigated in samples of Apis cerana from Yunnan, China. A fragment of about 480 bp in tRNAleu-COII, including a noncoding area and part of COII, was sequenced. The noncoding area was 97-98 bp; 8 haplotypes were found, among which 5 had been reported previously, while 3 ... more

We present polymorphic microsatellite markers isolated for genetic studies of the sugarcane borer, Diatraea saccharalis (Fabricius). We isolated 16 microsatellite loci through an enriched genomic library protocol. After characterization, 12 markers showed polymorphic information expressed in the observed number of alleles (ranging from 2 to 7; 5 on average) and in the ... more

Dipsacus chinensis; Genetic diversity; Inter-simple sequence repeat

Wild Dipsacus chinensis plants in China have become endangered owing to over-harvesting and habitat fragmentation. We examined the genetic diversity and genetic structure of 90 individuals from three populations using inter-simple sequence repeat markers and found that 106 of 173 bands amplified by 22 informative and reliable primers were polymorphic. These findings correspond to ... more

AFLP; Genetic diversity; Procambarus clarkii; Yangtze River

The red swamp crayfish has become one of the most important freshwater aquaculture species in China. At present, although it is widely distributed in the middle and lower reaches of the Yangze River basin, little is known about its population genetics and geographic distribution in China. We estimated the genetic diversity among 6 crayfish populations from 4 lakes (Hongze Lake, Poyang ... more
