Isolation and characterization of eight polymorphic microsatellite loci for the coconut pest, Brontispa longissima (Coleoptera: Hispidae)
Authors: C.L. Ma, H.L. Wu, H.Y. Hu, X. Wu, G.C. Ma, Y.G. Fu and Z.Q. Peng
Brontispa longissima is one of the most serious insect pests of coconut in Southeast Asia; it was first discovered on Hainan Island in June 2002. Despite the economic risk associated with this pest, genetic aspects of the invasion process have remained relatively unexplored. Using microsatellite markers, we investigated the po.. Read More»

Genetic diversity of turmeric germplasm (Curcuma longa; Zingiberaceae) identified by microsatellite markers
Authors: M.S. Sigrist, J.B. Pinheiro, J.A. Azevedo Filho and M.I. Zucchi
Turmeric (Curcuma longa) is a triploid, vegetatively propagated crop introduced early during the colonization of Brazil. Turmeric rhizomes are ground into a powder used as a natural dye in the food industry, although recent research suggests a greater potential for the development of drugs and cosmetics. In Brazil, little is k.. Read More»

An insight in the genetic control and interrelationship of some quality traits in Brassica napus
Authors: S. Ahmad, H.A. Sadaqat, M.H.N. Tahir and F.S. Awan
A study on three leading lines (KN-256, KN-257, and KN-258) of Brassica napus and an approved variety, Punjab-Sarson, was conducted to gain insight into the genetic control of some quality traits using generation mean analysis. Our results showed that additive gene action predominated in the inheritance of oil content and erucic acid in cross KN-256 x KN-.. Read More»

Comparison of eight methods of genomic DNA extraction from babassu
Authors: J.P.G. Viana, A.N.C. Borges, A.C.A. Lopes, R.L.F. Gomes, F.B. Britto, P.S.C. Lima and S.E.S. Valente
Babassu (Orbignya phalerata Martius) is one of the most important palms in Brazil because of the largest morphological variation, wide geographic distribution, and high socio-economic importance. The diversity present in babassu germplasm should be protected against loss to ensure their use with high productivity. Study of the available variability in pop.. Read More»

Genes related to high temperature tolerance during maize seed germination
Authors: S.M.F. Dutra, E.V.R. Von Pinho, H.O. Santos, A.C. Lima, R.G. Von Pinho and M.L.M. Carvalho
The identification of genes related to heat tolerance is fundamental for the development of high-quality seeds that are tolerant to heat stress condition. The objective of this study was to evaluate maize lineages and the gene expression involved in high temperature tolerance during germination using physiological tests, proteomics, and transcriptome anal..

Physical location of the carotenoid biosynthesis genes Psy and �?²-Lcy in Capsicum annuum (Solanaceae) using heterologous probes from Citrus sinensis (Rutaceae)
Authors: V. Andrade-Souza, M.G.C. Costa, C.X. Chen, F.G. Gmitter Jr. and M.A. Costa
Carotenoids are responsible for a range of fruit colors in different hot pepper (Capsicum) varieties, from white to deep red. Color traits are genetically determined by three loci, Y, C1, and C2, which are associated with carotenogenic genes. Although such genes have been localized on genetic maps of Capsicum and anchored in L.. Read More»

Genetic characterization of papaya plants (Carica papaya L.) derived from the first backcross generation
Authors: H.C.C. Ramos, M.G. Pereira, F.F. Silva, L.S.A. Gon�?§alves, F.O. Pinto, G.A. de Souza Filho and T.S.N. Pereira
The limited number of papaya varieties available reflects the narrow genetic base of this species. The use of backcrossing as a breeding strategy can promote increases in variability, besides allowing targeted improvements. Procedures that combine the use of molecular markers and backcrossing permit a reduction of the time req.. Read More»

Cloning and characterization of the nicotianamine synthase gene in Eruca vesicaria subsp sativa
Authors: B.L. Huang, C. Cheng, G.Y. Zhang, J.J. Su, Y. Zhi, S.S. Xu, D.T. Cai, X.K. Zhang and B.Q. Huang
Nicotianamine (NA) is a ubiquitous metabolite in plants that bind heavy metals, is crucial for metal homeostasis, and is also an important metal chelator that facilitates long-distance metal transport and sequestration. NA synthesis is catalyzed by the enzyme nicotianamine synthase (NAS). Eruca vesicaria subsp sativa is highly tolerant to Ni, Pb, and Zn. .. Read More»

Isolation and characterization of 16 microsatellite loci in marble goby (Oxyeleotris marmoratus)
Authors: J. Luo, X.P. Zhu, Y.H. Peng and S.W. Yin
A microsatellite-enriched genomic library for marble goby (Oxyeleotris marmoratus), a freshwater fish of considerable economic value, was obtained. A total of 16 microsatellite markers were successfully isolated and characterized in a population from the Mekong River in Vietnam. These markers had 2-20 alleles with expected heterozygosity ranging from 0.03.. Read More»

Effects of different dwarfing interstocks on key enzyme activities and the expression of genes related to malic acid metabolism in Red Fuji apples
Authors: J. Shi, F.F. Li, H. Ma, Z.Y. Li and J.Z. Xu
In this experiment, the test materials were ‘Red Fuji’ apple trees grafted onto three interstocks (No. 53, No. 111, and No. 236), which were chosen from SH40 seeding interstocks. The content of malic acid, the enzyme activities, and the expression of genes related to malic acid metabolism were determined during fruit development.The results sh.. Read More»
