Genetic Diversity
Characterization of SNPs in strawberry cultivars in China
Authors: A.J. Ge J. Han X.D. Li M.Z. Zhao H. Liu Q.H. Dong J.G. Fang
Single nucleotide polymorphisms (SNPs) occur at high frequencies in both plant and animal genomes and can provide broad genome coverage and reliable estimates of genetic relationships. The availability of expressed sequence tag (EST) data has made it feasible to discover SNPs. DNA analysis is crucial in genetic studies not only for strawberry breeding progra.. Read More»

Genetic diversity of Saccharum officinarum accessions in Pakistan as revealed by random amplified polymorphic DNA
Authors: F.A. Khan, A. Khan, F.M. Azhar and S. Rauf
Genetic diversity of 20 sugarcane accessions in Pakistan was studied using 21 random amplified polymorphic DNA markers. The mean genetic distance between the cultivars was 39.03%, demonstrating that a large part of the genome is similar among the accessions. This probably arises from a lack of parental diversity, with few clon.. Read More»

Phylogeny of Marmosops and the occurrence of Marmosops pinheiroi (Pine, 1981) (Didelphimorphia, Didelphidae) in the Cerrado savanna of Maranh�£o, Brazil
Authors: D.C. Nascimento, A.P.M. OlÃ?Âmpio, E. ConceiÃ?§Ã?£o, B.A.T.P. Campos, E.C. Fraga and M.C. Barros
The present study reviews the phylogeny of the genus Marmosops and expands the geographic range of Marmosops pinheiroi to the Brazilian State of Maranhão. Five specimens of M. pinheiroi were collected from the Inhamum Municipal Environmental Protection Area in Caxias, Maranhão. Total DNA was extracted and the mitochondrial cytochrome b gene ..

Chloroplast analysis of Zelkova schneideriana (Ulmaceae): genetic diversity, population structure, and conservation implications
Authors: H.L. Liu1,2, R.Q. Zhang2, M.L. Geng3, J.Y. Zhu1, J.C. An1 and J.L. Ma1
elkova schneideriana is endemic to China and belongs to the Ulmaceae. It is listed as a Near Threatened species in the China Biodiversity Red Data Book. We conducted a phylogeographical study of two chloroplast regions (psbA-trnH and trnG-trnM) in several Chinese Z. schneideriana populations, in order to examine the genetic diversity, population structure..

Genetic diversity among red swamp crayfish (Procambarus clarkii) populations in the middle and lower reaches of the Yangtze River based on AFLP markers
Authors: B.F. Zhu Y. Huang Y.G. Dai C.W. Bi C.Y. Hu
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.. Read More»

Genetic diversity and population structure in Brazilian Mangalarga Marchador horses
Authors: J.B. DeAssis, D.M. DeLaat, M.G.C.D. Peixoto, J.A.G. Bergmann,C.G. Fonseca and M.R.S. Carvalho
One hundred and fifteen unrelated Mangalarga Marchador horses were sampled from three geographically distinct regions of Minas Gerais State, Brazil (South, Southeast, and Northeast) and tested for 10 microsatellite loci. Genetic diversity and population structure parameters were estimated with ARLEQUIN 3.0, CERVUS 2.0, POPGENE.. Read More»

New set of microsatellites for Chinese tallow tree, Triadica sebifera
Authors: Y.F. Zhuang, Z.F. Wang and L.F. Wu
Chinese tallow (Triadica sebifera) is an important crop and ornamental tree. After it was introduced into the USA, it gradually became a noxious invasive tree in south-eastern America since the middle of the 1900s. Because only six microsatellites were reported previously in T. sebifera, to better understand the genetic divers.. Read More»

Estimation of genetic distance between 10 maize accessions with varying response to different levels of soil moisture
Authors: M. Aslam, F.S. Awan, I.A. Khan and A.I. Khan
Ten maize accessions (NC-9, A50-2, M-14, B-42, NC-3, T-7, N-48-1, B-34, USSR, and WFTMS) were studied to estimate the genetic distance on molecular level by random amplified polymorphic DNA. These accessions were selected on the basis of their variable responses against different levels of moisture. Twenty-five primers were us.. Read More»

Conservation and population genetic diversity of Curcuma wenyujin (Zingiberaceae), a multifunctional medicinal herb
Authors: W.H. Zheng, Y. Zhuo, L. Liang, W.Y. Ding, L.Y. Liang and X.F. Wang
Curcuma wenyujin is an important multifunctional medicinal herb in China. Currently, populations of C. wenyujin are decreasing, and wild individuals have almost disappeared from their natural habitats. Moreover, little is known regarding the molecular characteristics of this plant. In this study, we investigated the genetic diversity and variation of five.. Read More»

Authors: W.N. Rodrigues, S.V.B. Brinate, L.D. Martins, T.V. Colodetti and M.A. Tomaz
The use of supplementary irrigation to sustain the plantation during moments of severe water stress or moments of high water demand is becoming almost a norm to keep sustainable crops, especially due to the climate changes and the high frequency in which climate extremes are occurring lately. The objective of this study was to.. Read More»
