self-incompatibility in almond and prunus species is an important genetic trait that prevents self-fertilization. self-incompatibility in almond is controlled gametophytically by the multiallelic s-locus. this study was done in order to identification and preliminary selection of self-compatible progenies resulted from controlled crosses in almond using specific primer sff-sfr.some important mo...

Self-incompatibility in almond and Prunus species is an important trait that prevents self-fertilization. Selfincompatibility in almond is controlled gametophytically by the multiallelic S-locus. Present study was done in order to identification and preliminary selection of self compatible progenies resulted from controlled crosses in almond using specific primer SfF/SfR. Some important morphol...

Polymorphism of the b-lactoglobulin (b-LG) gene in 101 cows belonging to the Holstein herd and a superior cow, producing more than 150 Kg milk/day, together with four offsprings was investigated by the Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP) method. In the Holstein herd, the alleles A and B of the b-LG gene had frequencies of 0.53 and 0.47, respectively. Th...

A method for genotyping hepatitis B virus by partial HBsAg gene sequencing with primers common to all known genotypes was developed. Mutations related to anti-HBs resistance are also detected with this method. Samples from 103 Brazilian patients were analyzed. Precore and core region of these viruses were also sequenced in 101 patients. Genotypes A, B, C, D, and F were found with frequencies of...

The study aimed to evaluate the genetic diversity of eight brinjal (Solanum melongena L.) genotypes including wild species and develop a molecular profile using 14 SSR primers. value similarity matrix ranged from 0.12–0.87. Dendrogram image is revealing relationship among brinjal. super cluster divided into two clusters A B at Jaccard’s coefficient 0.31. Cluster again divide sub A1 A2 0.45. con...

BACKGROUND Genetic and developmental disruption of surfactant protein B (SP-B) expression causes neonatal respiratory distress syndrome (RDS). OBJECTIVES To assess developmental and genetic regulation of SP-B expression in vivo. METHODS To evaluate in vivo developmental regulation of SP-B, we used immunoblotting to compare frequency of detection of mature and pro-SP-B peptides in developmen...

Drought is one of the major limitations to crop production worldwide. This study was conducted to evaluate the response of five almond genotypes and peach×almond hybrid GF to drought stress in vitro, and screening drought tolerance. Explants subjected to polyethylene glycol osmotic stress ( , , and . % WV) on the MS medium. Increasing PEG level in the medium significantly reduced fresh weight a...

OBJECTIVE To examine recent trends of acute infection with hepatitis B virus (HBV) in Japan by nationwide surveillance and phylogenetic analyses. METHODS During 1991 through 2009, a sentinel surveillance was conducted in 28 national hospitals in a prospective cohort study. Genotypes of HBV were determined in 547 patients with acute hepatitis B. Nucleotide sequences in the preS1/S2/S gene of g...
