Production and genetic analysis of resynthesized Brassica napus from a B. rapa landrace from the Qinghai-Tibet Plateau and B. alboglabra
Authors: H.D. Liu*, Z.G. Zhao*, D.Z. Du, C.R. Deng and G. Fu
This study aimed to reveal the genetic and epigenetic variations involved in a resynthesized Brassica napus (AACC) generated from a hybridization between a B. rapa (AA) landrace and B. alboglabra (CC). Amplified fragment length polymorphism (AFLP), methylation-sensitive amplified polymorphism, and the cDNA-AFLP technique were performed to detect changes b.. Read More»

LAMP-PCR detection of ochratoxigenic Aspergillus species collected from peanut kernel
Authors: H.M. Al-Sheikh
Over the last decade, ochratoxin A (OTA) has been widely described and is ubiquitous in several agricultural products. Ochratoxins represent the second-most important mycotoxin group after aflatoxins. A total of 34 samples were surveyed from 3 locations, including Mecca, Madina, and Riyadh, Saudi Arabia, during 2012. Fungal contamination frequency was det.. Read More»

Genetic gains in the UENF-14 popcorn population with recurrent selection
Authors: I.L.J. Freitas, A.T. do Amaral J�ºnior, S.P. Freitas Jr., P.D.S. Cabral, R.M. Ribeiro and L.S.A. Gon�§alves
The popcorn breeding program of Universidade Estadual do Norte Fluminense Darcy Ribeiro aims to provide farmers a cultivar with desirable agronomic traits, particularly with respect to grain yield (GY) and popping expansion (PE). We evaluated full-sib families from the seventh cycle of recurrent selection and estimated the gen.. Read More»

Association of the GSTT1 polymorphism in upper aerodigestive tract cancer with tobacco smoking
Authors: T.M. Silva, C.R. Marques, M.F. Marques Filho, A.B. Marques,G. Di Pietro and F. Rios-Santos
Polymorphisms in genes encoding xenobiotic-metaboli- zing enzymes might explain differences in the susceptibility to upper aerodigestive tract (UADT) cancers in individuals exposed to tobacco or other carcinogens. The present study aimed to evaluate the association of polymorphisms in the glutathione S-transferase (GST) candid.. Read More»

Optimization of DNA extraction from fresh leaf tissues of Melanoxylon brauna (Fabaceae)
Authors: D.B. Borges, M.B. Amorim, A.M. Waldschmidt, E. Mariano-Neto, C.V. Vivas and D.G. Pereira
Melanoxylon brauna (Fabaceae - Caesalpinioideae) is an endemic and valuable hardwood tree species in the Brazilian Atlantic rainforest; it is comparable to African ebony wood. We tested three protocols of DNA extraction based on the citrimonium bromide (CTAB) method and evaluated the quantity, purity and integrity of the DNA. .. Read More»

Diversity of endophytic fungal community associated with Piper hispidum (Piperaceae) leaves
Authors: R.C. Orlandelli, R.N. Alberto, C.J. Rubin Filho and J.A. Pamphile
Tropical and subtropical plants are rich in endophytic community diversity. Endophytes, mainly fungi and bacteria, inhabit the healthy plant tissues without causing any damage to the hosts. These fungi can be useful for biological control of pathogens and plant growth promotion. Some plants of the genus Piper are hosts of endophytic microorganisms; howeve.. Read More»

New microsatellite loci for the mandarin fish Siniperca chuatsi and their application in population genetic analysis
Authors: C.X. Tian, X.-F. Liang, M. Yang, Y.Q. Dou, H.Z. Zheng, L. Cao,Y.C. Yuan and C. Zhao
The mandarin fish is a popular fresh water food fish in China. Fifty-three polymorphic microsatellite markers were isolated through construction of an enriched library of genomic DNA of Siniperca chuatsi (Percichthyidae). We found 2 to 7 alleles per locus. The observed and expected heterozygosity values varied from 0.059 to 1... Read More»

Selecting elephant grass families and progenies to produce bioenergy through mixed models (REML/BLUP)
Authors: E.V. Rodrigues, R.F. Daher, A. dos Santos, M. Vivas, J.C. Machado, G. do A. Gravina, Y.P. de Souza, A.K. Vidal, A. dos S. Rocha and R.S. Freitas
Brazil has great potential to produce bioenergy since it is located in a tropical region that receives high incidence of solar energy and presents favorable climatic conditions for such purpose. However, the use of bioenergy in the country is below its productivity potential. The aim of the current study was to select full-sib.. Read More»

Africanized honey bees are efficient at detecting, uncapping and removing dead brood
Authors: M.M. Morais,T.M. Francoy,R.A. Pereira, D. De Jong, L.S. Gon�§alves
The hygienic behavior of honey bees is based on a two-step process, including uncapping and removing diseased, dead, damaged, or parasitized brood inside the cell. We evaluated during periods of 1 h the time that hygienic and non-hygienic colonies of Africanized honey bees spend to detect, uncap and remove pin-killed brood usi.. Read More»

Development and characterization of nine polymorphic microsatellites for the small brown planthopper Laodelphax striatellus (Hemiptera: Delphacidae)
Authors: J.-T. Sun, J.-B. Li, X.-M. Yang and X.-Y. Hong
Nine microsatellite loci were isolated from the genome of Laodelphax striatellus (Homoptera: Delphacidae) by constructing (TC)6(AC)5 and (AG)6(AC)5 compound SSR-enriched libraries using suppression-PCR procedures. These loci were found to be highly polymorphic, with 13 to 30 alleles per locus in the three populations that we i.. Read More»
