Chaudhary Charan Singh Haryana Agricultural University, Hisar

Chaudhary Charan Singh Haryana Agricultural University popularly known as HAU, is one of Asia's biggest agricultural universities, located at Hisar in the Indian state of Haryana. It is named after India's seventh Prime Minister, Chaudhary Charan Singh. It is a leader in agricultural research in India and contributed significantly to Green Revolution and White Revolution in India in the 1960s and 70s. It has a very large campus and has several research centres throughout the state. It won the Indian Council of Agricultural Research's Award for the Best Institute in 1997. HAU was initially a campus of Punjab Agricultural University, Ludhiana. After the formation of Haryana in 1966, it became an autonomous institution on February 2, 1970 through a Presidential Ordinance, later ratified as Haryana and Punjab Agricultural Universities Act, 1970, passed by the Lok Sabha on March 29, 1970. A. L. Fletcher, the first Vice-Chancellor of the university, was instrumental in its initial growth.

    Studies on biochemical basis for cotton leaf curl disease tolerance in Gossypium hirsutum L.
    (CCSHAU, 2018) Taranjeet Kaur; Mandhania, Shiwani
    Viruses have profound effect on the growth and productivity of plants. With reference to the cotton crop, CLCuD caused by CLCuBuV has been recognized as a serious threat to cotton production in Indian subcontinent. Information on cotton and CLCuV interaction is still not convincingly explained. In the present study, the constituents like RWC, electrolyte leakage, total chlorophyll content, MDA content, total soluble protein, total sugar content, total phenolics, H2O2, gossypol content and the activities of defense related proteins viz. POX, PPO, CAT and PAL were scrutinized at different stages of infestation in GCH 3, HS 6 genotypes of cotton and in additional genotype (HD 432) to look over the biochemical basis for CLCuD tolerance mechanism. It was found that the maximum RWC, total chlorophyll content and total soluble protein was present in highly tolerant and resistant genotype respectively at 0 DAI. Decline in the amount of these constituents reported in all genotypes but maximum loss took place in HS 6. Least amount of electrolyte leakage, H2O2 and MDA content was present in HD 432 at all stages of infestation. Significant increase in these parameters observed in HS 6 post incursion of virus. Maximum total sugar content was present in HS 6 at 0 DAI, ebb was more in GCH 3 due to infestation. As a consequence of viral infection, the level of total phenolic compounds and gossypol content increased significantly in all genotypes while maximum increase was in GCH 3. With the progression of infestation period significant increase was reported in the activities of PAL, PPO, POX and CAT in all genotypes. Thus, the increase in the level of total phenolic compounds, gossypol with increase in the activities of all studied enzymes can be correlated with the potency of the plant to strive against CLCuD.

    Extraction and evaluation of antioxidant capacity of total phenolics from lychee (Litchi chinensis L.) seeds
    (CCSHAU, 2018) Nagesh C.R.; Ajay Pal
    Lychee seed, being a biowaste, is an inexpensive source of a variety of polyphenols. However, extraction yield/efficiency of total phenolics from lychee seed powder (LSP) depends on extraction conditions. Hence, in present study, optimum conditions for extraction of phenolics from LSP were deduced using one-factor-at-a-time approach followed by response surface methodology (RSM). The factorial, axial and center point experiments of central composite rotatable design (CCRD) of RSM were carried out to investigate the linear, quadratic and interactive effects of three independent variables namely volume of extractant (ml/g), agitation rate (rpm) and extraction time (min) on the yield of phenolics. Regression analysis showed that ~92% of the variation could be explained by the model. Software mediated numerical optimization was done with the constraint of minimum volume of extractant and extraction time separately for maximum yield of TPC. The experimental values were in accordance with the predicted values, indicating the adequacy of model and success of RSM in optimizing the extraction conditions. Lychee seed extract (LSE) was analyzed for profiling of phenols and fatty acids using H-UPLC and GC, respectively. Despite reported phenolic compounds, we found new phenolics namely apigenin, catechol, catechin, chlorogenic acid, diadzein, salicyclic acid, trans-ferulic acid, trans-sinapic acid and vanillin in LSE. Among six different fatty acids identified, oleic acid and linoleic acid were abundant. Further, LSE was assayed for its antioxidant activities using an array of tests including free radical scavenging activity, nitric oxide scavenging activity (NOSA), hydroxyl radical scavenging activity, metal chelation activity, total antioxidant activity (TAA), total reducing power (TRP), lipid peroxidation inhibition activity (LPIA) and protein oxidation inhibition activity. Prokaryotic and eukaryotic DNA damage protective efficacy of LSE was also observed using pBR322 plasmid and human lymphocytes, respectively. Results of various experiments showed substantial antioxidant activity of LSE and advocate its exploitation as a source of natural antioxidants to counter ROS-induced pathologies or diseases.
