Genetic assessment of the Atlantic Forest bristle porcupine, Chaetomys subspinosus (Rodentia: Erethizontidae), an endemic species threatened with extinction
Authors: C.G. Oliveira, R.A. Martinez, G.A.F. Gin�©, D.M. Faria and F.A. Gaiotto
The bristle-spined porcupine, Chaetomys subspinosus, an endemic rodent from Atlantic Forest, was considered to be abundant in the recent past, but population reductions due to habitat loss and expansion of human activities caused this species to be included in the “vulnerable” category of the World Conservation Uni..

Polymorphisms in the leptin gene promoter in Brazilian beef herds
Authors: R.C. Guimar�£es, J.S.N. Azevedo, S.C. Corr�ªa, J.E.G. Campelo, E.M. Barbosa, E.C. Gon�§alves and E. Silva Filho
Brazil is the world’s largest producer of beef cattle; however, the quality of its herds needs to be improved. The use of molecular markers as auxiliary tools in selecting animals for reproduction with high pattern for beef production would significantly improve the quality of the final beef product in Brazil. The leptin.. Read More»

Comparative analysis of soybean genotype resistance to Heterodera glycines and Meloidogyne species via resistance gene analogs
Authors: P.M.H. Vieira, F.A.S. Ar�ªdes, A. Ferreira and M.F.S. Ferreira
Nematodes are important pests of soybean throughout the world and cause high yield losses. As a control strategy, the identification of resistance genes is an important aim of breeding studies. Plants possess resistance genes (R), which are responsible for the recognition of pathogens and activation of the defense system. R ge.. Read More»

Increased relatedness among the neighboring plants from seedling to adult stages in carna�ºba wax palm
Authors: F.A. Vieira, R.F. Sousa, C.G. Fajardo and M.M. Brand�£o
The objective of this study was to assess the spatial genetic structure (SGS) at different life stages (cohorts) in a remnant population (N = 101) of Copernicia prunifera in the semiarid region of northeastern Brazil. Using seven inter-simple sequence repeat molecular markers, we were able to analyze 93 loci with 100% polymorp.. Read More»

Genetic analysis of Apuleia leiocarpa as revealed by random amplified polymorphic DNA markers: prospects for population genetic studies
Authors: K.H. Lencina, E.R. Konzen, S.M. Tsai and D.A. Bisognin
Apuleia leiocarpa (Vogel) J.F. MacBride is a hardwood species native to South America, which is at serious risk of extinction. Therefore, it is of prime importance to examine the genetic diversity of this species, information required for developing conservation, sustainable management, and breeding strategies. Although scarce.. Read More»

Morphological, pathological and molecular variability in Botryodiplodia theobromae (Botryosphaeriaceae) isolates associated with die-back and bark canker of pear trees in Punjab, India
Authors: M.D. Shah, K.S. Verma, K. Singh and R. Kaur
Thirteen isolates of Botryodiplodia theobromae collected from pear varieties grown in various regions of Punjab were studied for morphological, pathological and molecular characterization. The mycelial growth of B. theobromae isolates was classified as fluffy or depressed, uniform to irregular and cottony white turning to blac.. Read More»

Assessing the genetic relationships of Curcuma alismatifolia varieties using simple sequence repeat markers
Authors: S. Taheri, T.L. Abdullah, N.A.P. Abdullah, Z. Ahmad, E. Karimi and M.R. Shabanimofrad
The genus Curcuma is a member of the ginger family (Zingiberaceae) that has recently become popular for use as flowering pot plants, both indoors and as patio and landscape plants. We used PCR-based molecular markers (SSRs) to elucidate genetic variation and relationships between five varieties of Curcuma (.. Read More»

Assessment of genetic relationship in Persea spp by traditional molecular markers
Authors: J.C. Reyes-Alem�¡n, E. Valadez-Moctezuma and A.F. Barrientos-Priego
Currently, the reclassification of the genus Persea is under discussion with molecular techniques for DNA analysis representing an alternative for inter- and intra-specific differentiation. In the present study, the traditional random-amplified polymorphic DNA (RAPD) and the inter simple sequence repeat (ISSR) markers were use.. Read More»
