FISH analysis and cytogenetic characterization of male meiotic prophase I in Acricotopus lucidus (Diptera, Chironomidae)
Authors: W. Staiber
In the chironomid Acricotopus lucidus, two cells with quite different chromosome complements arise from the last unequal spermatogonial mitosis, as a consequence of monopolar migration of the so-called germ line limited chromosomes (Ks). The cell receiving all the Ks, in addition to two sets of the regularly segregating somati.. Read More»

Molecular cloning and single nucleotide polymorphism analysis of IGF2a genes in the common carp (Cyprinus carpio)
Authors: S.Y. Su, Z.J. Dong, J.Q. Qu, Z.Y. Liang, J.Q. Zhang, L.X. Ma, W. Liu, P. Xu and X.H. Yuan
We studied whether two IGF2 transcripts in common carp are similar to those found in zebrafish. The full-length IGF2a cDNA contains a 5'-terminal untranslated region (UTR) of 105 bp, a 3'-terminal UTR of 1358 bp and an open reading frame of 612 bp, which encodes a 206-amino acid protein. A 6614-bp full-length IGF2a DNA molecul.. Read More»

Genetic diversity analysis of isolates of the fungal bean pathogen Pseudocercospora griseola from central and southern Brazil
Authors: A.K.R. Abadio, S.S. Lima, M.F. Santana, T.M.F. Salom�£o, A. Sartorato, E.S.G. Mizubuti, E.F. Ara�ºjo and M.V. de Queiroz
Planting resistant varieties is the most effective control measure against the angular leaf spot of dry beans, a fungal disease caused by Pseudocercospora griseola. However, dry bean varieties with durable resistance are not easily obtained. Knowledge about the genetic variability of the pathogen population is key for the succ.. Read More»

Characterization of Trypanosoma brucei gambiense variant surface glycoprotein LiTat 1.5
Authors: L. Van Nieuwenhove, S. Rog�©, V. Lejon, Y. Guisez and P. B�¼scher
At present, all available diagnostic antibody detection tests for Trypanosoma brucei gambiense human African trypanosomiasis are based on predominant variant surface glycoproteins (VSGs), such as VSG LiTat 1.5. During investigations aiming at replacement of the native VSGs by recombinant proteins or synthetic peptides, the seq.. Read More»

Differential expression analysis of porcine MDH1, MDH2 and ME1 genes in adipose tissues
Authors: S.L. Zhou, M.Z. Li, Q.H. Li, J.Q. Guan and X.W. Li
Malate dehydrogenases 1 and 2 (MDH1 and MDH2), and malic enzyme 1 (ME1) play important roles in the Krebs cycle for energy metabolism. The mRNA abundance changes of MDH1, MDH2 and ME1 genes were measured across six different adipose tissues from the leaner Landrace and fatty Rongchang pig breeds using quantitative real-time PC..

Genetic progress in the UNB-2U population of popcorn under recurrent selection in Rio de Janeiro, Brazil
Authors: R.M. Ribeiro, A.T. do Amaral J�ºnior, L.S.A. Gon�§alves, L.S. Candido, T.R.C. Silva and G.F. Pena
As part of the Universidade Estadual do Norte Fluminense recurrent selection program of popcorn, we evaluated full-sib families of the sixth cycle of recurrent selection and estimated genetic progress for grain yield and expansion capacity. We assessed 200 full-sib families for 10 agronomic traits, in a randomized block design.. Read More»

Genome-wide identification and characterization of simple sequence repeat loci in grape phylloxera, Daktulosphaira vitifoliae
Authors: H. Lin, M.S. Islam and D.W. Ramming
A genome-wide sequence search was conducted to identify simple sequence repeat (SSR) loci in phylloxera, Daktulosphaira vitifoliae, a major grape pest throughout the world. Collectively, 1524 SSR loci containing mono-, di-, tri-, tetra-, penta-, and hexanucleotide motifs were identified. Among them, trinucleotide repeats were .. Read More»

Identification and characterization of a novel Iraqi isolate of Fusarium pseudograminearum causing crown rot in wheat
Authors: M.A. Hameed, R.M. Rana and Z. Ali
Crown rot is one of the main important fungal diseases affecting wheat in many areas of the world, including Australia, USA, and Iran. Until now, there had been no report of this pathogen in Iraq. Plants displaying crown rot symptoms were observed in Shaat Alarab (Basra, Iraq); we investigated the causal agent of the disease. .. Read More»

Molecular characterization of a mariner-like element in the Atta sexdens rubropilosa genome
Authors: P. Rezende-Teixeira, J.B. do Amaral, F. Siviero and G.M. Machado-Santelli
Mobile elements are widely present in eukaryotic genomes. They are repeated DNA segments that are able to move from one locus to another within the genome. They are divided into two main categories, depending on their mechanism of transposition, involving RNA (class I) or DNA (class II) molecules. The mariner-like elements are.. Read More»

Mutations in NPHS1 in a Chinese child with congenital nephrotic syndrome
Authors: Z.H. Yu, D.J. Wang, D.C. Meng, J. Huang and X.J. Nie
Since the identification of the NPHS1 gene, which encodes nephrin, various investigators have demonstrated that the NPHS1 mutation is a frequent cause of congenital nephrotic syndrome (CNS); it is found in 98% of Finnish children with this syndrome and in 39-80% of non-Finnish cases. In China, compound heterozygous mutations i.. Read More»
