Validation of EST-derived microsatellite markers for two Cerrado-endemic Campomanesia (Myrtaceae) species
Authors: E.A.G.C. Miranda1, C.R.D. Boaventura-Novaes2, R.S. Braga1, E.F. Reis3,J.F.N. Pinto3 and M.P.C. Telles1
We assessed the transferability of 120 EST-derived Eucalyptus microsatellite primers to Campomanesia adamantium and C. pubescens. Both species are berry trees native to the Brazilian Cerrado, and population genetic information is poor. Twelve markers were used to analyze the genetic variability of four sampled populations. Regarding DNA extraction, we sam.. Read More»

Selection of processing tomato genotypes with high acyl sugar content that are resistant to the tomato pinworm
Authors: D.M. Dias J.T.V. Resende M.V. Faria L.K.P. Camargo R.R. Chagas I.P. Lima
Acyl sugars are allelochemicals present at high concentrations in leaves of accessions of the wild tomato Solanum pennellii; they confer resistance to a large number of arthropod pests, including the tomato pinworm, Tuta absoluta (Lepidoptera, Gelechiidae). Accession 'LA716', with high contents of acyl sugars in the leaves, was used as a source of resista.. Read More»

Identification and cloning of GOLDEN2-LIKE1 (GLK1), a transcription factor associated with chloroplast development in Brassica napus L.
Authors: Y.L. Pan, Y. Pan, C.M. Qu, C.G. Su, J.H. Li and X.G. Zhang
Photosynthesis is the process by which dry matter accumulates, which affects rapeseed yield. In this study, we identified GOLDEN2-LIKE1 (GLK1), located on chromosome A07 and 59.2 kb away from the single nucleotide polymorphism marker SNP16353A07, which encodes a transcription factor associated with the rate of photosynthesis i..

Use of simple sequence repeat markers for DNA fingerprinting and diversity analysis of sugarcane (Saccharum spp) cultivars resistant and susceptible to red rot
Authors: U. Hameed, Y.-B. Pan, K. Muhammad, S. Afghan and J. Iqbal
Red rod is an economically important disease of sugarcane caused by the fungus Colletotrichum falcatum. We used a simple sequence repeat (SSR)-based marker system to identify and analyze genetic relationships of red rot resistant and susceptible sugarcane cultivars grown in Pakistan. Twenty-one highly polymorphic SSR markers w.. Read More»

Genetic relationships in a germplasm collection of Camellia japonica and Camellia oleifera using SSR analysis
Authors: Y. Zhao, C.J. Ruan, G.J. Ding and S. Mopper
Camellia japonica produces different color and bigger flowers, widely being used for gardening green in southern China. However, cultivars were introduced from different regions, but their origin and pedigree information is either not available poorly documented, causing problems in authentication. Many low-yield trees in Came.. Read More»

Comparative evaluation of total RNA extraction methods in Theobroma cacao using shoot apical meristems
Authors: D.V. Silva1, S.M.J. Branco1, I.S.A. Holanda2, S. Royaert3, J.C. Motamayor4,J.P. Marelli4 and R.X. Corr�ªa5
Theobroma cacao is a species of great economic importance with its beans used for chocolate production. The tree has been a target of various molecular studies. It contains many polyphenols, which complicate the extraction of nucleic acids with the extraction protocols requiring a large amount of plant material. These issues, therefore, necessitate the op..
