Cloning, characterization and overproduction of nuclease S1 gene (nucS) from Aspergillus oryzae
Applied Microbiology and Biotechnology, 1995The nuclease S1 gene (nucS) from Aspergillus oryzae was isolated using a polymerase-chain-reaction-amplified DNA fragment as a probe, and a 2.6-kb SalI-EcoRI fragment containing the nucS gene was sequenced. It was deduced that the nucS gene had two short introns, 49 and 50 nucleotides in length. The nucS gene had an open-reading frame of 963 base pairs

Buchnera aphidicola is a prokaryotic endosymbiont found in specialized cells of the aphid Schizaphis graminum. Many of the previously cloned B. aphidicola genes are preceded by a poor ribosome-binding site. Ribosomal protein S1 (RpsA) allows the translation of messenger RNAs that lack or have a poor ribosome binding site. We have cloned and sequenced a

Infectious bronchitis (IB), caused by infectious bronchitis virus (IBV), is a highly contagious chicken disease, and can lead to serious economic losses in poultry enterprises. The continual introduction of new IBV serotypes requires alternative strategies for the production of timely and safe vaccines against the emergence of variants. Modification of

In order to select mutants that would help to characterize the post-transcriptional regulation of rpsA, we constructed a strain in which the growth rate on lactose minimal medium is determined by the amount of an rpsA-lacZ' alpha-fragment fusion protein produced, even when this is encoded by a high-copy-number plasmid. In the parental strain, synthesis

Gene transfer systems were developed in Rubrivivax (Rx.) gelatinosus S1. First, a system for conjugative transfer of mobilizable plasmids from Escherichia coli to Rx. gelatinosus S1 was established. Secondly, optimal conditions for the transformation of Rx. gelatinosus S1 by electroporation were determined.

Molecular cloning and characterization of buffalo alpha(s1)-casein gene.
DNA sequence : the journal of DNA sequencing and mapping, 2008Buffaloes in Indian subcontinent play an important role as the producer of milk and milk products. The alpha(s1)-casein constitutes 38% of the total milk proteins. The present study was carried out to characterize the gene in Murrah breed of Riverine buffalo.

Infectious bronchitis virus (IBV) isolates recovered in Russia, Ukraine, and Kazakhstan between 2007 and 2010 were subjected to molecular characterization and compared with those isolated a decade ago. The IBV genome was detected in 202 out of 605 field samples from chickens with various clinical signs.

AbstractGametophytic self‐incompatibility (GSI) is controlled by a highly polymorphic locus called the S‐locus, which is an important factor that can result in seedless fruit in Citrus. The S1 self‐incompatibility locus‐linked pollen 3.15 gene (S1‐3.15) belongs to a type of S locus gene. The role of S1‐3.15 in the SI reaction of Citrus has not yet been
