Genetic diversity in wild Dipsacus chinensis populations from China based on ISSR markers
Authors: D.-X. Chen, L.-Y. Li, X. Zhang, Y. Wang and Z. Zhang
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. The.. Read More»

Genetic diversity among Puccinia melanocephala isolates from Brazil assessed using simple sequence repeat markers
Authors: R.F. Peixoto-Junior, S. Creste, M.G.A. Landell, D.S. Nunes, A. Sanguino, M.F. Campos, R. Vencovsky, E.V. Tambarussi and A. Figueira
Brown rust (causal agent Puccinia melanocephala) is an important sugarcane disease that is responsible for large losses in yield worldwide. Despite its importance, little is known regarding the genetic diversity of this pathogen in the main Brazilian sugarcane cultivation areas. In this study, we characterized the gen.. Read More»

Genetic diversity in fragmented populations of Populus talassica inferred from microsatellites: implications for conservation
Authors: X.H. Zhu, S.P. Cheng, T. Liao and X.Y. Kang
Populus talassica Kom. is an ecologically important species endemic to central Asia. In China, its main distribution is restricted to the Ili region in the Xinjiang Autonomous Region. An understanding of genetic diversity and population structure is crucial for the development of a feasible conservation strategy. Twenty-six hi.. Read More»

Assessment of genetic diversity of wheat genotypes by resistance gene analog-EST markers
Authors: O. Karakas, F. Gurel and A.A. Uncuoglu
Resistance gene analog-expressed sequence tag (RGA-EST)-based markers have been used for variety discrimination and studies of genetic diversity in wheat. Our aim is to increase the competitiveness of public wheat breeding programs through intensive use of modern selection technologies, mainly marker-assisted selection. The ge.. Read More»

Genetic structure of Pilosocereus gounellei (Cactaceae) as revealed by AFLP marker to guide proposals for improvement and restoration of degraded areas in Caatinga biome
Authors: E.R. Monteiro, D.K. Strioto, A.C.S. Meirelles, C.A. Mangolin and M.F.P.S. Machado
Amplified fragment length polymorphism (AFLP) analysis was used to evaluate DNA polymorphism in Pilosocereus gounellei with the aim of differentiating samples grown in different Brazilian semiarid regions. Seven primer pairs were used to amplify 703 AFLP markers, of which 700 (99.21%) markers were polymorphic. The percentage of polymorphic markers ranged .. Read More»

Cytoplasmic polymorphism and evolutionary history of plum cultivars: Insights from chloroplast DNA sequence variation of trnL-trnF spacer and aggregated trnL intron & trnL-trnF spacer
Authors: S.B. Mustapha,H. Ben Tamarzizt,G. Baraket,D. Abdallah and A. Salhi-Hannachi
We screened for polymorphisms of the non-coding region of plastid DNA in plum trees. Sequencing data from the trnL-trnF chloroplast region were used to reveal a pattern of diversity, establish phylogenetic relationships, and test the selection pressure or evolutionary demography scenario for plastome DNA. The size of the non-coding regions varied from 398.. Read More»

Molecular diversity analysis of eggplant (Solanum melongena) genetic resources
Authors: Z. Ali, Z.L. Xu, D.Y. Zhang, X.L. He, S. Bahadur and J.X. Yi
Eggplant (Solanum melongena), a vegetable that is cultivated worldwide, is of considerable importance to agriculture in China. We analyzed the diversity of this plant using inter-simple sequence repeat (ISSR) and RAPD procedures to subdivide 143 Chinese-cultivated eggplants based on coefficient of parentage, genetic diversity ..

Genetic diversity in mutated and non-mutated rice varieties
Authors: M. Naeem, F. Ghouri, M.Q. Shahid, M. Iqbal, F. S. Baloch, L. Chen, S. Allah, M. Babar and M. Rana
We studied the genetic variability due to mutation induced by γ-rays (10, 15, and 20 Kr) on various traits of twelve rice genotypes. Mutated and non-mutated seeds were sown in the field between July 2013 and 2014 using a split plot design. Yield and yield-related trait data was recorded, which showed significant (P < 0.05) genotypic and irradiati.. Read More»
