摘要:
The invention is in the field of agriculture, in particular in the field of crop protection, more particularly in the field of providing nematode resistance to plants. A method for producing a plant having improved nematode resistance, particularly to root-knot nematodes and/or cyst nematodes, is disclosed, as well as a plant produced by such method.

Described herein is a process of genetic transformation in W. somnifera by Agrobacterium tumefaciens mediated transformation to overexpress squalene synthase gene (WsSQS) encoding WsSQS enzyme that catalyzes the synthesis of squalene from farnesyl pyrophosphate. Increased withanolide level including withaferin-A, withanolide A and B and withanone is attained in transformed plant tissues.
摘要:
The present invention relates to plants having increased pre-formed defense, their production and uses. The invention more particularly discloses plants which overexpress a p33kD or BURP protein, or an ortholog thereof, and exhibit an increased pre-formed resistance to pathogens.
摘要:
Multimeric hybrid genes encoding the corresponding chimeric protein comprise a gene sequence coding for an antigenic region of a protein from a first pathogen linked to a gene sequence coding for an antigenic region of a protein from a second pathogen. The pathogens particularly are parainfluenza virus (PIV) and respiratory syncytial virus (RSV). A single recombinant immunogen is capable of protecting infants and similar susceptible individuals against diseases caused by both PIV and RSV.

The invention concerns a hybrid plasmid for the expression of unfused 38 kDa antigen of M. tuberculosis in E. coli, E. coli with the plasmid, an 38 kDa antigen and a protein of about 33 kDa useful for diagnoses.
摘要:
The invention concerns an in vitro process for altering the insect host range (spectrum) or increasing the toxicity of lepidopteran active B.t. crystal protein toxins. The process comprises recombining in vitro the variable region(s) (non-homologous) of two or more genes encoding lepidopteran active B.t. crystal protein toxins. Specifically exemplified is the recombining of the variable regions of two genes obtained from well-known strains of Bacillus thuringiensis var. kurstaki. The resulting products are chimeric toxins which are shown to have an expanded and/or amplified lepidopteran insect host range as compared to the parent toxins.
摘要:
A novel surface exposed protein of Haemophilus influenzae or related Haemophilus species is described. The protein named protein D is an Ig receptor for human IgD and has an apparent molecular weight of 42,000. Protein D can be detected in all of 116 encapsulated and non-encapsulated isolates of H. influenzae studied. The protein from all strains shows in addition to the same apparent molecular weight immunogenic similarities since protein D from all strains interacts with three different mouse monoclonal antibodies and monoclonal human IgD. A method for purification of protein D is described. Cloning of the protein D gene from H. influenzae in E. coli is described as well as the nucleotide sequence and the deduced amino acid sequence.

摘要:
Regions of the PspA protein of the R.times.1 strain of Streptococcus pneumoniae have been identified as containing protection-eliciting epitopes which are cross-reactive with PspAs of other S. pneumoniae strains and which is cross-protective. One region comprises the 68-amino acid sequence extending from amino acid residues 192 to 260 of the R.times.1 PspA strain while another region comprises the C-terminal amino acid sequence extending from amino acid residues 293 to 588 of the R.times.1 PspA strain.
