DNA methylation in sugarcane somaclonal variants assessed through methylation-sensitive amplified polymorphism
Authors: J.H.M.B. Francischini, E.L. Kemper, J.B. Costa, J.R.V. Manechini and L.R. Pinto
Micropropagation is an important tool for large-scale multiplication of plant superior genotypes. However, somaclonal variation is one of the drawbacks of this process. Changes in DNA methylation have been widely reported as one of the main causes of somaclonal variations in plants. In order to investigate the occurrence of ch.. Read More»

Trap-nesting bees (Hymenoptera: Apoidea) in forest fragments of the state of S�£o Paulo, Brazil
Authors: A.L. Gazola and C.A. Gar�³falo
We studied the community ecology of trap-nesting bees in two forest fragments of the state of São Paulo, Brazil, during two years, utilizing bamboo canes and tubes made of black cardboard as trap nests. The traps were inspected once a month with an otoscope. One hundred and fifteen nests were obtained at Estaç&at.. Read More»

Genetic divergence among Psidium accessions based on single nucleotide polymorphisms developed for Eucalyptus
Authors: S.R. Costa and C.A.F. Santos
The goal of this study was to analyze the genetic divergence among Psidium species accessions based on SNPs developed for Eucalyptus. Fifty-three Psidium accessions, including 47 P. guajava, were genotyped with EUCHIP60K. The dendrogram similarity ranged from 0.58 to 1.00, with a cophenetic value of 0.97. Five groups were iden..

Performance of peanut mutants and their offspring generated from mixed high-energy particle field radiation and tissue culture
Authors: J.S. Wang, L.X. Qiao, L.S. Zhao, P. Wang, B.T. Guo, L.X. Liu and J.M. Sui
To develop new ways to breed peanut, we irradiated seeds of the Luhua 11 cultivar with a mixed high-energy particle field at different doses. The embryonic leaflets were extracted as explants and incubated on somatic embryo induction medium and then on somatic embryo germination and regeneration medium. After being grafted, the M1-generation plants were t.. Read More»

Cuticular hydrocarbons in the stingless bee Schwarziana quadripunctata (Hymenoptera, Apidae, Meliponini): differences between colonies, castes and age
Authors: T.M. Nunes, I.C.C. Turatti, S. Mateus, F.S. Nascimento,N.P. Lopes and R. Zucchi
Chemical communication is of fundamental importance to maintain the integration of insect colonies. In honey bees, cuticular lipids differ in their composition between queens, workers and drones. Little is known, however, about cuticular hydrocarbons in stingless bees. We investigated chemical differences in cuticular hydrocar.. Read More»

Analysis of genetic diversity of Leuciscus leuciscus baicalensis using novel microsatellite markers with cross-species transferability
Authors: D.J. Lei, G. Zhao, P. Xie, Y. Li, H. Yuan, M. Zou, J.G. Niu and X.F. Ma
We used next-generation sequencing technology to characterize 19 genomic simple sequence repeat (SSR) markers and 11 expressed sequence tag (EST) SSR markers from Leuciscus leuciscus baicalensis, a small freshwater fish that is widely distributed in Xinjiang, China. Primers were used to test for polymorphisms in three L. leuci.. Read More»

Thunbergia laurifolia extract minimizes the adverse effects of toxicants by regulating P-glycoprotein activity, CYP450, and lipid metabolism gene expression in HepG2 cells
Authors: A. Rocejanasaroj, T. Tencomnao and W. Sangkitikomol
Thunbergia laurifolia (TL) is widely used as an antidote in Thai traditional medicine against toxic substances such as alcohol, pesticides, arsenic, and strychnine. We found that the lyophilized form of TL in 80% ethanol possessed the antioxidant levels within the range 23,163.9 ± 1457.4 Trolox equivalents mM/kg dry mas.. Read More»

Rearing Africanized honey bee (Apis mellifera L.) brood under laboratory conditions
Authors: I.C. Silva, D. Message, C.D. Cruz, L.A.O. Campos and M.J. Sousa-Majer
We developed a method for rearing larvae of Africanized bees under laboratory conditions to determine the amount of diet needed during larval development to obtain a worker bee. We started with larvae 18-24 h old, which were transferred to polyethylene cell cups and fed for five days. We found that the amount of diet needed fo.. Read More»

Diversity of plant growth-promoting bacteria associated with sugarcane
Authors: J.E.L. Antunes, M.C.C.P. Lyra, F.J. Ollero, A.D.S. Freitas, L.M.S. Oliveira, A.S.F. Ara�ºjo and M.V.B. Figueiredo
The sugarcane (Saccharum spp) presents economic importance, mainly for tropical regions, being an important Brazilian commodity. However, this crop is strongly dependent on fertilizers, mainly nitrogen (N). This study assessed the plant growth-promoting bacteria (PGPB) associated with sugarcane that could be used as a potentia.. Read More»

Strategy for selection of soybean genotypes tolerant to drought during germination
Authors: S.A.G. Dantas, F.C.S. Silva, L.J. Silva and F.L. Silva
Water deficit is the main reason for instability in the context of soybean culture. The development of strategies for the selection of more tolerant genotypes is necessary. These strategies include the use of polyethylene glycol 6000 solutions (PEG-6000) for conducting the germination test under conditions of water restriction.. Read More»
