Genetic relationships analysis of olive cultivars grown in China
Authors: M.M. Zhan, Z.Z. Cheng, G.C. Su, A.Y. Wang, H.P. Chen, Z.S. Yang, Z. Shan and Q.M. Huang
The olive tree is an iconic tree of the Mediterranean, and is used extensively to produce high-quality olive oil. Although the China olive industry has just begun to be valued, there were also existed mislabeling and synonyms in introduced cultivars. The aim of this study was to analyze genetic similarities among olive cultivars in China using SSR and ISS.. Read More»

Genetic variability of Myzus persicae nicotianae densovirus based on partial NS and VP gene sequences
Authors: X.R. Song, S.H. Tang, Z.Q. Tang, X.M. Yang, X.W. Wang, X.F. Wang, P.J. Xu and G.W. Ren
We previously described a novel densovirus [Myzus persicae nicotianae densovirus (MpnDV)] infecting M. persicae nicotianae (Hemiptera: Aphididae) with 34% prevalence. This single-stranded DNA virus has a 5480-nucleotide ambisense genome and belongs to the Densovirinae subfamily within the family Parvoviridae. In the present st.. Read More»

Frequency of the Val1016Ile mutation on the kdr gene in Aedes aegypti (Diptera: Culicidae) in south Brazil
Authors: M.L. Collet, C. Frizzo, E. Orlandin, L.D.P. Rona, J.C. Nascimento, M.A.E. Montano, G.A. M�¼ller and G. Wagner
Recently, the number of Aedes aegypti foci has increased in west of Santa Catarina, south Brazil, which has increased concern regarding mosquito-borne disease outbreaks such as dengue fever, Zika virus, and chikungunya. Therefore, it is important to monitor genetic resistance to insecticides through “knockdown resistance.. Read More»

Genetic diversity of Aquilegia (Ranunculaceae) species and cultivars assessed by AFLPs
Authors: R.R. Zhu, Y.K. Gao, L.J. Xu and Q.X. Zhang
Species of the genus Aquilegia are exceptionally diverse in their floral morphology and color, commonly known as columbine. They are widely planted ornamentals and are highly attractive for hummingbirds. However, little is known about their genetic diversity. We examined the genetic diversity of the species and cultivars using.. Read More»

RAPD-based genetic diversities and correlation with morphological traits in Camellia (Theaceae) cultivars in China
Authors: X.F. Wang, H.Y. Zheng, W.H. Zheng, C.Q. Ao, H.Y. Jin, L.H. Zhao, N. Li and L.R. Jia
Camellia is an economically important ornamental plant that has many uses, such as in beverages, foods and medicines. We examined 15 Camellia cultivars in Wenzhou, China, using RAPD markers and measurements of three traits (petal color, flower diameter, blooming period). PCR amplification with 15 random primers produced 1935 b.. Read More»

Genetic diversity and mycelial compatibility groups of the plant-pathogenic fungus Sclerotinia sclerotiorum in Brazil
Authors: C.G. Litholdo J�ºnior, E.V. Gomes, M. Lobo J�ºnior, L.C.B. Nasser and S. Petrofeza
The genetic variability of 40 Sclerotinia sclerotiorum isolates from various fields widely distributed throughout Brazil and different host crops was analyzed using RAPD markers and mycelial compatibility groupings (MCGs). The isolates were characterized using 16 random primers of the OPERON series, which produced 121 DNA frag.. Read More»

Development of a cassava core collection based on single nucleotide polymorphism markers
Authors: E.J. Oliveira, C.F. Ferreira, V.S. Santos and G.A.F. Oliveira
Single nucleotide polymorphism (SNP) markers were used in the largest cassava (Manihot esculenta Crantz) germplasm collection from Brazil to develop core collections based on the maximization strategy. Subsets with 61, 64, 84, 128, 256, and 384 cassava accessions were selected and named PoHEU, MST64, PoRAN, MST128, MS.. Read More»

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..

Genetic characterization of Curraleiro P�©-Duro bovine breed from a conservation herd of Brazilian semiarid
Authors: E. Silva Filho, M.H. Silva, J.E.G. Campelo, M.R. DeRosia,L.M.L. Pinheiro and M.J.O. Almeida
Curraleiro Pé-Duro is a rustic bovine taurine breed found in Northeast of Brazil; this breed has decreased its production potentially in order to adapt to the region environment conditions. Consequently, it is under risk of extinction and is maintained at a preservation center in Piauí State, Brazil, as a source .. Read More»
