Characterization and comparison of transgenic Artemisia annua GYR and wild-type NON-GYR plants in an environmental release trial
Authors: H. Liu, G.G. Wu, J.B. Wang, X. Wu, L. Bai, W. Jiang, B.B. Lv, A.H. Pan, J.W. Jia, P. Li, K. Zhao, L.X. Jiang and X.M. Tang
The anti-malarial drug, artemisinin, is quite expensive as a result of its slow content in Artemisia annua. Recent investigations have suggested that genetic engineering of A. annua is a promising approach to improve the yield of artemisinin. In this study, the transgenic A. annua strain GYR, which has high artemisinin content, was evaluated in an environ.. Read More»

Simulating the selfing and migration of Luehea divaricata populations in the Pampa biome to investigate the conservation potential of their genetic resources
Authors: C.M.L. Serrote, L.R.S. Reiniger, V.M. Stefenon, A.R. Curti, L.S. Costa and A.F. Paim
Computer simulations are an important tool for developing conservation strategies for forest species. This study used simulations to investigate the genetic, ecological, and reproductive patterns that contribute to the genetic structure of the tree Lueheadivaricata Mart. & Zucc. in five forest fragments in the Brazilian Pa..

Genetic structure based on nuclear and chloroplast microsatellite loci of Solanum lycocarpum A. St. Hil. (Solanaceae) in Central Brazil
Authors: K. Martins, L.J. Chaves, R. Vencovsky and P.Y. Kageyama
Solanum lycocarpum (Solanaceae) is a woody species found in the Brazilian Cerrado. The flowers are pollinated by Xylocopa spp bees, and seeds are dispersed by mammals with distinct home range sizes. As a consequence, relative contributions of pollen and seeds to overall gene flow can vary according to different spatial scales... Read More»

Nested clade phylogeographical analysis of the finless porpoise (Neophocaena phocaenoides) inhabiting Chinese and Japanese coasts
Authors: L. Li, J. Jiang, X. Wang and X. Jiang
The finless porpoise (Neophocaena phocaenoides) is a small cetacean whose survival is largely affected by human activity. The characteristics and structures of 3 populations in China and 4 to 5 populations in Japan have been well documented, although their history and origins remain poorly understood. In this study, nested clade phylogeographical analysis.. Read More»

Bee�s morphometrics and behavior in response to seasonal effects from ecoregions
Authors: A.R.S. Sousa, E.D. Ara�ºjo, K.P. Gramacho and L.A. Nunes
In the present study, we used morphological and behavioral analyses to assess the effects of seasonality and morphoclimatic patterns on the morphology, behavior, and distribution of 71 colonies of Africanized honey bees in 3 distinct ecoregions (Zona da Mata, Agreste, and Sertão) within the State of Sergipe, north-easte..

Development and characterization of microsatellite loci for genetic studies of the sugarcane borer, Diatraea saccharalis (Lepidoptera: Crambidae)
Authors: V.A.C. Pavinato, K.L. Silva-Brand�£o, M. Monteiro, M.I. Zucchi, J.B. Pinheiro, F.L.F. Dias and C. Omoto
We present polymorphic microsatellite markers isolated for genetic studies of the sugarcane borer, Diatraea saccharalis (Fabricius). We isolated 16 microsatellite loci through an enriched genomic library protocol. After characterization, 12 markers showed polymorphic information expressed in the observed number of alleles (ranging from 2 to 7; 5 on averag.. Read More»

Expressed sequence tag-simple sequence repeat-based molecular variance in two Salicornia (Amaranthaceae) populations
Authors: Z.L. Xu, Z. Ali, J.X. Yi, X.L. He, D.Y. Zhang, G.H. Yu, A.A. Khan, I.A. Khan and H.X. Ma
Salicornia spp is one of the most salt-tolerant vascular plants and is native to salt marshes and estuaries. We developed expressed sequence tag derived-simple sequence repeat (EST-SSR) markers for estimating genetic diversity and marker-assisted Salicornia breeding. Six polymorphic EST-SSRs of 40 detected 27 alleles, ranging .. Read More»

Population genetic structure of the migratory rice leaf roller, Cnaphalocrocis medinalis (Lepidoptera: Pyralidae), inferred from the mitochondrial A+T-rich region and nuclear ITS2 sequences
Authors: X. Wan, J. Li, M.J. Kim, T.H. Kang, B.R. Jin and I. Kim
The population genetics of the migratory rice leaf roller, Cnaphalocrocis medinalis (Lepidoptera: Pyralidae), was characterized using the maternally inherited mitochondrial A+T-rich region and bi-parentally inherited nuclear internal transcribed spacer 2 (ITS2). One hundred and eighty-seven specimens of the rice leaf roller co.. Read More»

Gene flow between cassava, Manihot esculenta Crantz, and wild relatives
Authors: N.M.A. Nassar
Controlled and natural hybridization between cassava and wild relatives does occur. Barriers within the genus appear to be weak due to recent evolution of the group. All Manihot species examined cytogenetically have a chromosome number of 2n = 36. However, they behave meiotically as diploids. The weak interspecific barriers ha.. Read More»
