Authors: H.R. Ning, J.L.Wang, S.Y. Qin, S.Y. Huang, Z.L. Lou, L.Y. Hu and X.Q. Zhu
Toxoplasma gondii, an opportunistic protozoan parasite, infects almost all warm-blooded animals. In this study, we examined the sequence variation in rhoptry protein 20 (ROP20) genes among 18 T. gondii isolates collected from different hosts and geographical regions. Full length ROP20 genes were amplified and sequenced. The results showed that the genes w.. Read More»

Comparison of efficiency of distance measurement methodologies in mango (Mangifera indica) progenies based on physicochemical descriptors
Authors: E.O.S. Alves, C.B.M. Cerqueira-Silva, A.M. Souza, C.A.F. Santos, F.P. Lima Neto and R.X. Corr�?ªa
We investigated seven distance measures in a set of observations of physicochemical variables of mango (Mangifera indica) submitted to multivariate analyses (distance, projection and grouping). To estimate the distance measurements, five mango progeny (total of 25 genotypes) were analyzed, using six fruit physicochemical descr.. Read More»

Comparison of five DNA extraction methods for molecular analysis of Jerusalem artichoke (Helianthus tuberosus)
Authors: T. Mornkham, P.P. Wangsomnuk, P. Wangsomnuk, S. Jogloy, A. Pattanothai and Y.B. Fu
DNA extraction is an essential step for molecular analysis of an organism, but it is difficult to acquire a sufficient amount of pure DNA from plant tissue with high levels of phenolic compounds, carbohydrates, proteins, and secondary metabolites. Jerusalem artichoke (Helianthus tuberosus) has high levels of such substances. W.. Read More»

Genetic diversity of Brazilian and introduced olive germplasms based on microsatellite markers
Authors: A.D.B. do Val, J.L. Ferreira, J. Vieira Neto, M. Pasqual, A.F. de Oliveira, A. Bor�?©m and G.M.A. Can�?§ado
Olive trees have been grown since the beginning of civilization, and the consumption of olives and olive products is increasing worldwide, due to their health benefits and organoleptic qualities. To meet the growing market for olives, commercial cultivation of this species is expanding from traditional areas to new regions. Al.. Read More»

Physical localization of molecular markers and assignment of the 15th linkage group to chromosome 11 of the karyotype in cassava (Manihot esculenta Crantz) by primed in situ labeling
Authors: Y. Wang, J.F. Wang, H. Yin, H.Q. Gao, N.S. Zhuang and J.P. Liu
Physical localization of molecular markers and assignment of the 15th linkage group to chromosome 11 of the karyotype in cassava (Manihot esculenta Crantz) were achieved using primed in situ labeling. Amplified signals for both the EST507-1 and SSRY13-5 markers were consistently observed in different stages of cell division. A comparison of the length, ar.. Read More»

Genetic diversity in populations of Acrocomia aculeata (Arecaceae) in the northern region of Minas Gerais, Brazil
Authors: D.A. Oliveira, A.F. Melo J�?ºnior, M.M. Brand�?£o, L.A. Rodrigues, E.V. Menezes and P.R.B. Ferreira
Macaúba (Acrocomia aculeata) is a palm of economic importance, widely distributed in natural forests from Mexico to Uruguay. We analyzed the genetic diversity of populations of macaúba (A. aculeata) in the northern region of the State of Minas Gerais, Brazil. Young leaves from 10 macaúba individuals encomp.. Read More»

Establishment of an in vitro regeneration system for genetic transformation of selected sugarcane genotypes
Authors: S. Ijaz, I.A. Rana, I.A. Khan and M. Saleem
A good culture system provides considerable quantities of highly regenerable target tissues. Embryogenic callus cultures are ideal for micro-projectile-mediated transformation, because regenerable cells are not very stable. Effective exploitation of genetic transformation requires good regeneration systems. We selected three s.. Read More»

Genetic diversity and differentiation in Camellia reticulata (Theaceae) polyploid complex revealed by ISSR and ploidy
Authors: B.-Y. Wang and Z.-Y. Ruan
Camellia reticulata is a well-known ornamental and oil plant that is endemic to southwest China. This species shows three cell ploidies, i.e., diploidy, tetraploidy and hexaploidy. We made the first investigation of genetic diversity and differentiation of natural populations of C. reticulata, and 114 individuals from 6 popula.. Read More»

Identification of differentially expressed genes involved in early bolting of Angelica sinensis (Apiaceae)
Authors: G. Yu, Y.X. Ma, J.-A. Duan, B.S. Song and Z.Q. He
Angelica sinensis is a highly valued medicinal herb, known as female ginseng that is widely cultivated in China. Although A. sinensis is in great demand due to its multiple medicinal and food applications, its early bolting rate (almost 40%) seriously affects crop quality. To better understand its flowering mechanism, cDNA-amp.. Read More»

Polymorphisms in different EST-SSR types derived from the Chinese bayberry (Myrica rubra, Myricaceae) transcriptome
Authors: S.Y. Zhang, C. Feng, C.J. Xu, C.Q. Zhu and K.S. Chen
Most plant expressed sequence tag-simple sequence repeats (EST-SSRs) are not polymorphic, and it is important to learn the characteristics of highly polymorphic EST-SSRs. In this study, 357 compound and 5557 non-compound EST-SSRs, identified from the transcriptome of the Chinese bayberry (Myrica rubra ‘Biqi’), were divided into 11 types based .. Read More»
