Kerala Agricultural University, Thrissur

The history of agricultural education in Kerala can be traced back to the year 1896 when a scheme was evolved in the erstwhile Travancore State to train a few young men in scientific agriculture at the Demonstration Farm, Karamana, Thiruvananthapuram, presently, the Cropping Systems Research Centre under Kerala Agricultural University. Agriculture was introduced as an optional subject in the middle school classes in the State in 1922 when an Agricultural Middle School was started at Aluva, Ernakulam District. The popularity and usefulness of this school led to the starting of similar institutions at Kottarakkara and Konni in 1928 and 1931 respectively. Agriculture was later introduced as an optional subject for Intermediate Course in 1953. In 1955, the erstwhile Government of Travancore-Cochin started the Agricultural College and Research Institute at Vellayani, Thiruvananthapuram and the College of Veterinary and Animal Sciences at Mannuthy, Thrissur for imparting higher education in agricultural and veterinary sciences, respectively. These institutions were brought under the direct administrative control of the Department of Agriculture and the Department of Animal Husbandry, respectively. With the formation of Kerala State in 1956, these two colleges were affiliated to the University of Kerala. The post-graduate programmes leading to M.Sc. (Ag), M.V.Sc. and Ph.D. degrees were started in 1961, 1962 and 1965 respectively. On the recommendation of the Second National Education Commission (1964-66) headed by Dr. D.S. Kothari, the then Chairman of the University Grants Commission, one Agricultural University in each State was established. The State Agricultural Universities (SAUs) were established in India as an integral part of the National Agricultural Research System to give the much needed impetus to Agriculture Education and Research in the Country. As a result the Kerala Agricultural University (KAU) was established on 24th February 1971 by virtue of the Act 33 of 1971 and started functioning on 1st February 1972. The Kerala Agricultural University is the 15th in the series of the SAUs. In accordance with the provisions of KAU Act of 1971, the Agricultural College and Research Institute at Vellayani, and the College of Veterinary and Animal Sciences, Mannuthy, were brought under the Kerala Agricultural University. In addition, twenty one agricultural and animal husbandry research stations were also transferred to the KAU for taking up research and extension programmes on various crops, animals, birds, etc. During 2011, Kerala Agricultural University was trifurcated into Kerala Veterinary and Animal Sciences University (KVASU), Kerala University of Fisheries and Ocean Studies (KUFOS) and Kerala Agricultural University (KAU). Now the University has seven colleges (four Agriculture, one Agricultural Engineering, one Forestry, one Co-operation Banking & Management), six RARSs, seven KVKs, 15 Research Stations and 16 Research and Extension Units under the faculties of Agriculture, Agricultural Engineering and Forestry. In addition, one Academy on Climate Change Adaptation and one Institute of Agricultural Technology offering M.Sc. (Integrated) Climate Change Adaptation and Diploma in Agricultural Sciences respectively are also functioning in Kerala Agricultural University.

    Isolation and Characterization of cDNA encoding chalcone synthase from flower buds of orchid Dendrobium variety sonia 17
    (Department of Plant Biotechnology, College of Agriculture, Vellayani, 2007) Anjana, G R; KAU; Soni, K B
    The study entitled “Isolation and characterization of cDNA encoding chalcone synthase gene from the flower buds of orchid Dendrobium variety Sonia 17” was conducted at the Department of Plant Biotechnology, Vellayani, Thiruvananthapuram during the period from 2005 to 2007 with an objective of studying the isolation and characterization of cDNA encoding chalcone synthase gene involved in anthocyanin pigmentation in orchid flower buds. . Heterologous forward and reverse primers were designed based on the gene sequences of Oryza sativa, Fragaria ananasa and Phalaneopsis orchid using primer3 software. Total RNA was isolated from immature floral tissues using hot phenol method which gave an yield of 80 - 200 μg g -1 of the tissue and a A260/A280 ratio ranging between 1.6 –2.0. Messenger RNA was purified from the total RNA using the mRNA purification kit from GENEI (Bangalore). Reverse transcription-polymerase chain reaction was carried out to study the expression of gene. The RT-PCR amplified products representing chalcone synthase (CHS) gene was eluted and purified. The product was sequenced and studied the similarity of the same using homology search. All sequenced regions were subjected to BLASTN and BLASTX similarity search. Rice chalcone synthase specific primer produced an amplified sequence of 460 bp long and showed maximum similarity to the cDNA clone 5', mRNA sequence of. flower bud of Phalaenopsis violacea and flower bud of Phalaenopsis equestris Lambda ZapII cDNA Library in BLASTN similarity search.BLASTX analysis of the sequence showed similarity to maturase K protein of Aerangis kirki. The cDNA amplified with strawberry chs specific primer showed maximum similarity to the cDNA clone 5’, mRNA sequence of Phalaenopsis violacea flower bud and flower bud of Phalaenopsis equestris in the BLASTN similarity search. BLASTX analysis of the sequence showed similarity to LFY-like protein of Serapias lingua. The results of the nucleotide to nucleotide search (BLASTN) of the cDNA of orchid, amplified using chalcone synthase specific primer from orchid showed similarity to cDNA 5', mRNA sequence of Ipomoea batatas in the BLASTN similarity search. BLASTX analysis of the sequence showed similarity to retrotransposon protein of Oryza sativa (japonica cultivar-group). The result of the sequences obtained from the study shows similarity with the genes involved in the biosynthetic pathway of Phalaenopsis orchid flower fragrance.
