  • Insecticidal chitinase protein its encoding nucleotide and application thereof
    Patent number: 10006014
    Abstract: A novel insecticidal chitinase protein from fern Tectaria sp., a process for preparation of the insecticidal protein and nucleic acid sequence encoding for said insecticidal protein and its application for insect control purposes.
    Type: Grant
    Filed: March 29, 2016
    Date of Patent: June 26, 2018
    Assignee: Council of Scientific & Industrial Research
    Inventors: Pradhyumna K. Singh, Santosh K. Upadhyay, Chandrashekar Krishnappa, Sharad Saurabh, Rahul Singh, Preeti Rai, Harpal Singh, Manisha Mishra, Ajit P. Singh, Praveen C. Verma, Kuttan P. Narayanan, Rakesh Tuli
  • leaf agglutinin recombinant protein, its encoding polynucleotide, primer and process for preparation thereof
    Patent number: 9545107
    Abstract: Nucleic acid sequence encoding Allium fistulosum leaf agglutinin (AFAL) is disclosed. The invention provides Allium fistulosum leaf agglutinin (AFAL) recombinant protein, its encoding nucleotides, primers and the process of preparation thereof, said recombinant protein is useful for insect control and haemagglutination activity. AFAL is found more toxic to sap sucking insect pest Aphis gossypii (cotton aphid) and Bemisia tabaci (whiteflies) as compared to known Allium sativum leaf agglutinin. AFAL can be used in the development of transgenic plants for resistance against sap sucking and chewing pests.
