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.

    Engineering drought tolerant traits in rice
    (University of Agricultural Sciences, Bengaluru, 2013-06-29) B. H, Nagaveni; N, Nataraja karaba
    Plants being sessile are persistently exposed to various abiotic stresses, which are inevitable and less predictable. So, it is crucial to understand the mechanism that may help the plant to tolerate the stress conditions. Abiotic stress tolerance is multigenic character and stress responsive genes involved in this complex mechanism are many, among which transcription factors (TFs) are the major regulators of gene expression in plants. TFs, which play a crucial role in stress tolerance of plants, assume great importance in the development of tolerant crop varieties. Since the threshold for tolerance differs amongst the species, identification and functional characterization of genes/TFs from stress adapted crop species assumes importance. The present study involves improving drought tolerance by overexpressing TFs associated with intrinsic cellular tolerance and water conservation in a rice genotype AC39020 having a few drought tolerant traits. The candidate genes were cloned from drought hardy grass species Cenchrus ciliaris and tolerant rice landrace, Dodiga. The NFY-B1 was cloned from C. ciliaris, while the SKIP1 and SHN1 were cloned from Dodiga using PCR based cloning approach. Transformation protocol for the genotype AC39020 was developed and the three transgenes were overexpressed in isolation and co-expressed simultaneously in single plant. Evaluation of transgenic plants at seedling stage under different abiotic stresses using physiological, biochemical and growth parameters indicated the relevance of theses genes. The transgenic plants showed improved drought tolerance and grain yield by reduced spikelet sterility. Co-expression of three TFs is relevant in improving cellular tolerance in rice.
