M. Saravana Kumar; Ramesh, S.V.; Sugitha Thankappan; Naga Prafulla Chandrika Nulu; Asish Kanakaraj Binodh; Sundaravelpandian Kalaipandian; Ramachandran SrinivasanGlutaredoxins (Grxs) are small, ubiquitous and multi-functional proteins. They are present in different compartments of plant cells. A chloroplast targeted Class I GRX (CcGRXS12) gene was isolated from Capsicum chinense during the pepper mild mottle virus (PMMoV) infection. Functional characterization of the gene was performed in Nicotiana benthamiana transgenic plants transformed with native C. chinense GRX (Nb:GRX), GRX-fused with GFP (Nb:GRX-GFP) and GRX-truncated for chloroplast sequences fused with GFP (Nb:Δ2MGRX-GFP). Overexpression of CcGRXS12 inhibited the PMMoV-I accumulation at the later stage of infection, accompanied with the activation of salicylic acid (SA) pathway pathogenesis-related (PR) transcripts and suppression of JA/ET pathway transcripts. Further, the reduced accumulation of auxin-induced Glutathione-S-Transferase (pCNT103) in CcGRXS12 overexpressing lines indicated that the protein could protect the plants from the oxidative stress caused by the virus. PMMoV-I infection increased the accumulation of pyridine nucleotides (PNs) mainly due to the reduced form of PNs (NAD(P)H), and it was high in Nb:GRX-GFP lines compared to other transgenic lines. Apart from biotic stress, CcGRXS12 protects the plants from abiotic stress conditions caused by H2O2 and herbicide paraquat. CcGRXS12 exhibited GSH-disulphide oxidoreductase activity in vitro; however, it was devoid of complementary Fe–S cluster assembly mechanism found in yeast. Overall, this study proves that CcGRXS12 plays a crucial role during biotic and abiotic stress in plants.Item Central composite design, Pareto analysis, and artificial neural network for modeling of microwave processing parameters for tender coconut water(2022-01-01) Pandiselvam, R.; V. Prithviraj; Manikantan, M.R.; Shameena Beegum; Ramesh, S.V.; Sugatha Padmanabhan; Anjineyulu Kothakota; Mathew, A.C.; Hebbar, K.B.; Amin Mousavi KhaneghahPolyphenol oxidases (PPO) and peroxidases (POD) are the major enzymes that affect the quality of tender coconut water (TCW). Advanced thermal treatment such as microwave treatment has the potential for the inactivation of food enzymes. The experiments were conducted at three different microwave power levels (450, 600, and 900 W) and five different exposure times (70, 80, 90, 100, 110, and 120 s). The modeling and optimization of process parameters were done using a central composite design and artificial neural network. The microwave power level of 600 W for 120 s exposure time was suitable for enzyme inactivation with minimal quality loss. Optimized treatment has pH = 5.02, total soluble solids (TSS) = 5.68 °Brix, turbidity = 12.51 NTU, titratable acid (TA) = 0.07% of malic acid, PPO = 0, POD = 0, phenolic content = 37.238 mg GAE/L and overall acceptability (OA) = 7.5. These results confirmed that microwave treatment could be the potential alternative to conventional thermal treatment for processing tender coconut water.Item Cocoa(2017) Ramesh, S.V.; Ginny Antony; Tony GraceItem Coconut(2017) Neema, M.; Rajesh, M.K; Ramesh, S.V.; Chowdappa, PItem Coconut oil – scientific facts(2019-08) Ramesh, S.V.; Veda Krishnan; Shelly Praveen; Hebbar, K.BItem Comparative biochemical features of wild-type and purple cashew (Anacardium occidentale L.)(2024-10-27) N.V. Jyothi; Akhil Ajith; B. Ramesha; Hebbar, K.B; Ramesh, S.V.The comparative biochemical features of both the wild-type and purple-coloured cashew apple varieties are presented. The total soluble sugar content in purple cashew apples was higher (13.96%) than that in normal cashew apples (6.78%). Compared with purple cashews, wild-type cashew apples have a high titratable acidity (0.224%) as they contain more ascorbic acid (342.85 mg/100 g) than purple cashew apples (228.57 mg/100 g). The total polyphenol content of purple fruit leaves (8.04 mg GAE/g), peels (4.532 mg GAE/g), and pulp (2.067 mg GAE/g) was higher than that of wild-type cashews. Additionally, the flavonoid content (9.423 mg/g in leaves, 4.923 mg/g in apple peels, and 3.688 mg/g in cashew pulp) was higher in the purple cashew than in the wild-type cashews. Chlorophyll a, b, and total chlorophyll contents in wild-type cashew leaves (0.287 mg/g, 0.176 mg/g, and 0.463 mg/g, respectively) were greater than those in purple cashew leaves. However, the chlorophyll concentration in the fruit was found to be very minimal. Although the carotenoid content of the fruit was high in the wild-type cashew (22.83 g/100 g), the carotenoid concentration in the purple cashew leaves (83.475 g/100 g) was greater than that in the normal cashew leaves. Analysis of the anthocyanin contents suggested that the leaves and peels of plants with the purple genotype had relatively high anthocyanin contents (38.499 mg cyanidin-3-glucoside equivalents/kg (C3GE/kg) and 25.87 mg C3GE/kg) compared to those of plants with the wild-type cashews (0.157 and 0.951 mg C3GE/kg, respectively). These biochemical constituents of purple cashew suggest its potential application in the development of cashew apple-based nutritional products.Item Comparative conventional and phenomics approaches to assess symbiotic effectiveness of Bradyrhizobia strains in soybean (Glycine max L.

B; Vishnuvardhana; Hebbar, K.B.; Ramesh, S.V.; Venkatesh J; G. S. Chikkanna; B. N. Maruthi Prasad; B. S. HarishItem Detection of Oil Adulteration in Virgin Coconut Oil (VCO) Utilizing Chemometrics and Principal Component Analysis(2023-06-09) M. B. Cariappa; Ramesh, S.V.; G. S. Chikkanna; J. Venkatesh; Vishnuvardhana; Hebbar, K.B..; A. K. SinghAuthentication of virgin coconut oil (VCO) is imperative to protect the interests of the consumers. An investigation was carried out to distinguish VCO from coconut oil (CO), palm oil (PO) and liquid paraffin utilizing biochemical quality parameters, including fatty acid composition, and principal component analysis (PCA). Various oil blends of VCO: PO, VCO: CO (both in 10% increments), VCO:CO:PO and VCO: liquid paraffin and CO: liquid paraffin were prepared. The oil blends were analyzed for quality features, fatty acid composition and the data was analyzed statistically. Biochemical attributes such as total phenolic content (TPC), total flavonoid content (TFC), iodine value (IV) and saponification value (SV) and fatty acids like lauric acid, myristic acid, palmitic acid and oleic acid were influential parameters to distinguish the oil samples at various levels of adulteration. Samples could be classified even with the adulteration level of as low as 10%. Principal component analysis produced two components distinguishing various adulterated oil samples. Multiple regression analysis provided predictive equation models with high coefficient of determination ( R2) and could help in adulteration quantitation. Hence, this study demonstratedItem Dynamics of biochemical attributes and enzymatic activities of pasteurized and bio-preserved tender coconut water during storage(2022) Pandiselvam, R.; V. Prithviraj; Manikantan, M.R.; Shameena Beegum; Ramesh, S.V.; Anjineyulu Kothakota; Mathew, A.C.; Hebbar, K.B.; Cristina Maria Maerescu; Florin Leontin Criste; Claudia Terezia Socol
