Authors: T.C. Soares, J.M.F.C. Carvalho, L.M. Lima, R.M.M. Freire,C.R.C. Silva, P.A. Melo Filho and R.C. Santos
Zygotic and embryonic cotton structures were used in in vitro procedures to obtain stable plants. Zygotes (24, 48, and 72 h) and immature embryos (10 and 25 days after fertilization) were grown in MS medium supplemented with glucose, indoleacetic acid, kinetin, and activated charcoal. Regenerated seedlings were acclimatized an.. Read More»

Antimicrobial activity of essential oil and growth of Ocimum basilicum (L.) inoculated with mycorrhiza and humic substances applied to soil
Authors: F. Morelli, L. Ferarrese, C.L. Munhoz and O. Alberton
Mycorrhizal association increases the absorption of water and nutrients by plants, and thus, affects their metabolism. This study aimed at assessing the single and conjoint effects of the arbuscular mycorrhizal fungus (AMF) Claroideoglomus etunicatum and soil’s humic substances (HS) on the composition of essential oil (E..

Soybean genotype analysis for cyst nematode resistance
Authors: B.C.M. Juliatti, I.F. Beloti, L.C. Pena and F.C. Juliatti
Some species of soybean cultivars have the characteristic of resistance or alteration in survival skills, and perpetuation of nematodes (female index - FI), whose process is activated when the nematode parasitism starts and the development of new resistant cultivars is primordial to the preservation of plant productivity. The .. Read More»

Association of monocyte chemoattractant protein-1 rs1024611 and telomerase rs2736100 polymorphisms with susceptibility to pulmonary tuberculosis in Han Chinese population
Authors: G.H. Cheng, X.L. Wang, X.T. Yuan, Q. Xin, Q. Sun, K.L. Li, C. Sun, Z.M. Lin, Y. Luan, Y.S. Wang, F. Kong and D.W. Xu
Pulmonary tuberculosis (PTB) is caused by Mycobacterium tuberculosis infection and accumulated evidence reveals the genetic context of its infection phenotypes. Monocyte chemoattractant protein-1 (MCP-1) rs1024611 variant is shown to be associated with PTB susceptibility in some studies, but significant disparities exist. In a.. Read More»

Farmer variety exchange along Amazonian rivers influences the genetic structure of manioc maintained in a regional Brazilian Gene Bank
Authors: S.B. Sousa, G.F. Silva, M.C. Dias, C.R. Clement and N.R. Sousa
Knowledge of agro-morphological and genetic variability of germplasm diversity is a prerequisite for its use in breeding. The aim of this study was to characterize the genetic diversity of the manioc (Manihot esculenta) Active Germplasm Bank (AGB) at Embrapa Amazônia Ocidental using microsatellite markers. We evaluated 4.. Read More»

QTLs of morpho-agronomic traits in the Jalo x Small White common bean population
Authors: D.A. Souza, M. Balestre, A.K.A. Pamplona, L.R. Pinheiro, F.C. Alves, D.R. Pereira and J.B. Santos
In this study, we aimed to estimate the relationship between some common bean traits using molecular markers and applying QTL mapping. We used a segregating population derived from a crossing between common bean cultivars, Jalo and Small White, in the Southern State of Minas Gerais. Of F2 plants, 190 F2:3 progenies were genera..

Genetic variability in banana diploids and nonparametric statistics of fragments associated with natural fruit finger drop
Authors: M.A. Rodrigues, E.P. Amorim, C.F. Ferreira, C.A.S. Ledo and J.R.F. Santana
Natural fruit finger drop in bananas is one of the major concerns of producers as well as consumers. The aim of this study was to estimate the genetic diversity among 15 diploid bananas with different levels of resistance to finger drop (RFD) using SSR and ISSR (inter-simple sequence repeat) markers, and assess the possibility..
