Genetic structure of natural populations of Theobroma in the Juruena National Park, Mato Grosso State, Brazil
Authors: B.M. Silva, A.A.B. Rossi, J.F.E. Dardengo, C.R. Silva, I.V. Silva, M.L. Silva and C.J. Silva
Several species within the genus Theobroma have particularly high economic value, including T. cacao and T. grandiflorum. Other species in this genus, such as T. speciosum and T. subincanum, have potential value for use in the conservation of genetic diversity in breeding programs. These latter species could also be domesticated or improved to produce com.. Read More»

Biotools: an R function to predict spatial gene diversity via an individual-based approach
Authors: A.R. da Silva, G. Malafaia and I.P.P. Menezes
The gene diversity or expected heterozygosity (HE) is based on the allele frequency and is often used as a measure of genetic variability of populations. Knowing the pattern of spatial distribution of HE can be useful for determining strategies of conservation and sampling of collections of individuals. In addition, it can all.. Read More»

Population genetic characterization of the Japanese oak silkmoth, Antheraea yamamai (Lepidoptera: Saturniidae), using novel microsatellite markers and mitochondrial DNA gene sequences
Authors: S.R. Kim, K.Y. Kim, J.S. Jeong, M.J. Kim, K.-H. Kim, K.H. Choi and I. Kim
The Japanese oak silkmoth, Antheraea yamamai Guérin-Méneville, 1861 (Lepidoptera: Saturniidae), is an important natural resource of industrial value for silk fiber production. Owing to a lack of geographic and population genetic information, systematic domestication of An. yamamai has not been possible yet. In th.. Read More»

Conservation and population genetic diversity of Curcuma wenyujin (Zingiberaceae), a multifunctional medicinal herb
Authors: W.H. Zheng, Y. Zhuo, L. Liang, W.Y. Ding, L.Y. Liang and X.F. Wang
Curcuma wenyujin is an important multifunctional medicinal herb in China. Currently, populations of C. wenyujin are decreasing, and wild individuals have almost disappeared from their natural habitats. Moreover, little is known regarding the molecular characteristics of this plant. In this study, we investigated the genetic diversity and variation of five.. Read More»

Polymorphism and haplotype analyses of swine leukocyte antigen DQA exons 2, 3, 4, and their associations with piglet diarrhea in Chinese native pig
Authors: X.Y. Huang, Q.L. Yang, J.H. Yuan and S.B. Gun
In this study, 290 Chinese native Yantai black pig piglets were investigated to identify gene polymorphisms, for haplotype reconstruction, and to determine the association between piglet diarrhea and swine leukocyte antigen (SLA) class II DQA exons 2, 3, and 4 by polymerase chain reaction-single stranded conformational polymorphism and cloning sequencing...

Abnormal cytokinesis in microsporogenesis of Brachiaria humidicola (Poaceae: Paniceae)
Authors: E.V. Adamowski, K.R. Boldrini, M.S. Pagliarini, C.B. do Valle
Microsporogenesis was evaluated in the Brachiaria humidicola collection of the Embrapa Beef Cattle Center, represented by 60 accessions. One accession (H121) presented an abnormal pattern of cytokinesis that had never been reported in this genus. Among 900 meiocytes analyzed in the first division, 10.7% underwent precocious an..

Genetic variability and expression of agro-morphological traits among genotypes of Coffea arabica being promoted by supplementary irrigation
Authors: W.N. Rodrigues, S.V.B. Brinate, L.D. Martins, T.V. Colodetti and M.A. Tomaz
The use of supplementary irrigation to sustain the plantation during moments of severe water stress or moments of high water demand is becoming almost a norm to keep sustainable crops, especially due to the climate changes and the high frequency in which climate extremes are occurring lately. The objective of this study was to.. Read More»

A proposed selection index for feedlot profitability based on estimated breeding values
Authors: R.R. van der Westhuizen and J. van der Westhuizen
It is generally accepted that feed intake and growth (gain) are the most important economic components when calculating profitability in a growth test or feedlot. We developed a single post-weaning growth (feedlot) index based on the economic values of different components. Variance components, heritabilities and genetic corre.. Read More»

Gender flip-flop association between genetic variations of NEDD4L and metabolic syndrome in the Kazakh general population....
Authors: H.M. Wang, N.F. Li, J. Hong, L. Zhou and J.H. Chang
Genetic variation is thought to contribute to etiology of metabolic syndrome (MS). Neural precursor cell expressed developmentally downregulated 4-like gene (NEDD4L) is a candidate gene for MS. This study investigated the relationship between variations of NEDD4L and MS in the Kazakh, which is an ideal population to study the genetic mechanisms of complex.. Read More»
