Chaudhary Sarwan Kumar Himachal Pradesh Agriculture University, Palampur

Himachal Pradesh Krishi Vishvavidyalaya (renamed as Chaudhary Sarwan Kumar Himachal Pradesh Krishi Vishvavidyalaya in June, 2001) was established on 1st November, 1978.The College of Agriculture (established in May, 1966) formed the nucleus of the new farm University. It is ICAR accredited and ISO 9001:2015 certified institution. The Indian Council of Agricultural Research has ranked this University at eleventh place among all farm universities of the country. The University has been given the mandate for making provision for imparting education in agriculture and other allied branches of learning, furthering the advancement of learning and prosecution of research and undertaking extension of such sciences, especially to the rural people of Himachal Pradesh. Over the years, this University has contributed significantly in transforming the farm scenario of Himachal Pradesh. It has developed human resources, varieties and technologies and transferred these to farming community enabling the State to receive the “Krishikarman award” of Govt. of India four times in row for food grain production among small states of the country. Today, the State has earned its name for hill agricultural diversification and the farming community has imposed its faith in the University.

    SILENCING OF F-BOX KELCH GENE FOR VIRUS RESISTANCE STUDIES IN MODEL PLANT NICOTIANA BENTHAMIANA
    (CSKHPKV, Palampur, 2019) Garg, Shivanshu; Singh, Nageswer
    In the present investigation entitled ―Silencing of F-Box kelch gene for virus resistance studies in model plant Nicotiana benthamiana‖, construct has been prepared for generating the silent lines of the mentioned plant. F-Box kelch is an important protein that associates with the viral proteins and that the protein is an important factor that helps in the establishment of viral infection. A conserved portion of the gene was amplified in sense and antisense orientation and in a sequential manner it was cloned into the silencing vector pSAT4. The construct development was ascertained with the help of restriction digestion and sequence determination. The construct is ready to be transformed into plants. For the biochemical analysis, purified Cucumber mosaic virus (CMV) was inoculated at their 3-4 leaf stage and infection was confined by symptom development. Both infected and healthy plants were subjected to biochemical analysis of the phenolic compounds (total phenols, simple phenols, Ortho-dihydric phenols and bound phenols), alkaloids and total chlorophyll and carotenoids. It was observed that the total phenol content was increased in the infected plant in comparison to the healthy leaves. However, total chlorophyll and carotenoids were reduced in infected plants as compared to healthy leaves. This is expected as virus infection leads to loss of chlorophyll as reflected by mosaic symptoms that the virus produces.
