Research

Major research achievements

  • Micropropagation protocols have been perfected in 30 crop species which include spices, plantation crops, fruit crops, medicinal plants, vegetables, ornamentals etc.
  • Somaclonal variation has been exploited for crop improvement in ginger which led to the release of three ginger varieties “Athira, Karithika and Aswathy”
  • Fertilization in vitro perfected in ginger and Kacholam could produce seeds under in vitro conditions.
  • Protocols for genetic transformation were developed in black pepper, bell pepper, ginger and pumpkin.
  • Enhanced production of secondary metabolites through induction of hairy roots was observed in medicinal plants like Artemisia, Withania, Holostemma and Rauvolfia.
  • Protocols for in vitro conservation of germplasm in holostema, black pepper, vanilla and tylophora have been perfected.
  • DNA fingerprints of released varieties of black pepper, ginger, chillies, brinjal, cashew, cocoa and jack were developed.
  • Developed a non-pungent paprika type chilli line with resistance to bacterial wilt and suited for Kashmiri chilli powder production
  • Developed a pole type vegetable cowpea line with resistance to anthracnose and cowpea mosaic virus.
  • DNA barcodes were developed for species identification in Momordica, Benincasa, Praecitrullus and also in spidermites infesting crop plants.
  • Trait specific molecular markers were identified for resistance to ToLCV and bacterial wilt in tomato, bacterial wilt in chilli, pungency and colour in chilli , VSD and black pod rot in cocoa, bacterial leaf blight in rice, anthracnose in cowpea, yellow vein mosaic in okra and water stress in rice and black pepper.
  • Isolation and characterization of genes like Cry1AC and Cry4B , β 1-3 glucanase, hmgr, Chalcone synthase, Dihydro flavanol reductase, UDP glucose transferase, Capsaicinoid synthetase, Capsanthin capsorubin synthese, myo- inositol phosphate synthase, coat protein gene from cardamom mosaic virus and banana bract mosaic virus were done
  • Transcriptome research could deposit 48 ESTs related to drought tolerance in black pepper and 44 ESTs related to high gingerol content in ginger to NCBI.
  • Transcriptome analysis in black pepper for Phytophthora foot rot tolerance could identify two differentially expressed genes, Premnaspirodiene oxygenase and Phosphoserine phosphatase. Better expression and high copy number of β1-3 glucanase gene were detected for Phytophthora foot rot resistance in Piper colubrinum
  • Proteome analysis for drought tolerance in rice showed upregulation of certain proteins in traditional rice cultivar, Chuvanna Modan.
  • Comparison of proteome of yard long bean adopting organic and integrated management practices showed no difference in quality in both the management practices.
  • PR protein analysis by 2D-gel electrophoresis and MALDI-ToF in selected black pepper calli clone on challenge inoculation with Phytophthora capsici revealed direct role of TRAF-like family proteins in regulating programmed cell death and activation of F-box proteins to stimulate jasmonate regulated defense-related pathways in tolerant black pepper calliclone KLCC 89
  • Protocol for in vitro production of carotenoid from Byadagi chilli (Capsicum annuum L.) was standardized and elicitation with salicylic acid could scale up the in vitro carotenoid production. Upregulation of Capsanthine capsorubin synthase gene expression was observed in highest carotenoid yielding elicited Byadagi chilli calli.
  • Molecular docking and metabolome research carried out in coconut, spices and medicinal plants could identify numerous safe phytocompounds for major human diseases which are potential targets for drug development.
  • Nanobiosensors were developed in a collaborative project with Centre for Material Electronics, Thrissur for the easy and quick detection of banana bunchy top virus and banana bract mosaic virus.
  • In the DBT - BIRAC-CRS project on ginger metabolomics, Kerala Agricultural University, in association with Arjuna Natural Extracts Ltd., Aluva had developed a stable gingerol product with 8 per cent total gingerol from the high gingerol yielding variety “Karthika” released from Kerala Agricultural University. Provisional Indian patent was obtained for the product developed and for the process.
  • The in vitro microrhizome technology was perfected in three KAU ginger varieties viz. Athira, Karithika and Aswathy. Management practices for high tech poly house cultivation of in vitro microrhizomes for disease free ginger seed production and clean ginger production were standardized and technologies are ready for commercial exploitation
  • With in silico molecular docking, the centre has identified many safe phyto compounds from different spices and medicinal plants.
