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.

    Molecular cloning characterisation and functional analysis of growth arrest specific gene 2 in Pearlspot (Etroplus suratensis)
    (Department of Plant Biotechnology, College of Agriculture, Vellayani, 2019) Amiya Thalakkattu, KAU; Pradeep, M A
    Etroplus suratensis is the State fish of Kerala which is a delicacy which has very high economic value. Water temperature is a very important factor which affect the growth of Pearlspot. There are many genes expressed at water temperature stress. The objective of the study was “Molecular cloning, characterization and functional analysis of Growth Arrest Specific gene 2 in Pearlspot (Etroplus suratensis)”. The study was carried out at the maricuture facility, CMFRI, Kochi. Growth arrest specific gene 2 is a component of the microfilament system which plays a major role in cell death and apoptosis. This was studied to be highly expressed at cell contact inhibition, serum starvation and temperature stress The growth arrest specific gene was amplified using specific primers. The GAS2 ORF was found to be a 1017 bp sequence which was translated into a 388 amino acid sequence. The predicted molecular weight of GAS2 was found to be 38.7 k.Da. and was found to have calponin homology domain and GAS2 as conserved domains. In the study, fish juveniles were exposed to 3 water temperatures 26˚C, 30˚C and 32˚C for 72 hours. The muscle, brain and liver samples were collected at 1 hour, 12 hour and 72 hour. The expression was studied in each tissue sample by real time PCR assay. The expression patterns at each temperature and each duration was compared with the expression observed in 26˚C samples maintained as controls. The GAS2 expression was found to decrease proportional to the duration of exposure in fishes exposed to 30˚C when compared to that in the control sample maintained at 26˚C. The trend was found to be reverse in fish exposed to 32˚C, the expression increased at a constant level compared to the 26˚C control. In both experiments the highest expression was observed in muscle tissue and the lowest expression was found in liver tissue. GAS2 was found to be a stress related gene which show variable expression in different water temperatures with least expression in a range of above 26˚C and below 32 ˚C.
