University of Agricultural Sciences, Bengaluru

University of Agricultural Sciences Bangalore, a premier institution of agricultural education and research in the country, began as a small agricultural research farm in 1899 on 30 acres of land donated by Her Excellency Maharani Kempa Nanjammanni Vani Vilasa Sannidhiyavaru, the Regent of Mysore and appointed Dr. Lehmann, German Scientist to initiate research on soil crop response with a Laboratory in the Directorate of Agriculture. Later under the initiative of the Dewan of Mysore Sir M. Vishweshwaraiah, the Mysore Agriculture Residential School was established in 1913 at Hebbal which offered Licentiate in Agriculture and later offered a diploma programme in agriculture during 1920. The School was upgraded to Agriculture Collegein 1946 which offered four year degree programs in Agriculture. The Government of Mysore headed by Sri. S. Nijalingappa, the then Chief Minister, established the University of Agricultural Sciences on the pattern of Land Grant College system of USA and the University of Agricultural Sciences Act No. 22 was passed in Legislative Assembly in 1963. Dr. Zakir Hussain, the Vice President of India inaugurated the University on 21st August 1964.

    CHARACTERIZATION OF DROUGHT RESPONSIVE REGULATORY GENE IDENTIFIED FROM INDIAN MULBERRY (Morus alba L.)
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2017-10-27) ANJU, K.; Nataraja Karaba, N.
    Abiotic stresses limit plant growth and development. Faced with scarcity of water, drought is a serious threat to crop productivity and food security. Concerted efforts are being made to improve drought tolerance traits of crops. Stress tolerance depends on the coordinated regulation of several stress-related genes and associated acclimation pathways. Among several stress responsive genes, transcription factors (TFs) act as one of the major regulators which regulate the expression of down-stream genes involved in the acclimation process. From previous studies, basic Helix-Loop-Helix (bHLH) type of TFs were found to be associated with many biological processes, including abiotic stress response in plants. In a recent study, a stress responsive bHLH, MabHLH144-like has been cloned from mulberry and two transcript variants designated as MabHLH144a-like and MabHLH144b-like of size 1512bp and 1419bp, respectively have been identified. The variants were found to be differentially expressed in leaf tissues of mulberry maintained under different levels of drought stress by gravimetric approach. The 93bp deletion in one of the variants caused significant difference in the temporal distribution of expression in mulberry. To functionally validate the gene, transgenic Arabidopsis and Tobacco plants were developed to express MabHLH144b-like gene under a constitutive promoter. In-vitro regeneration assay of the transgenic Tobacco under salt (NaCl) stress condition produced tolerant phenotypes suggesting improvement in cellular tolerance, and the relevance of the gene in imparting stress tolerance. Critical analysis of the transgenic lines developed would give indications on the role of MabHLH144b-like in abiotic stress tolerance.
