Proteinase inhibitors: Plant-derived genes of insecticidal protein for developing insect-resistant transgenic plants
نویسندگان
چکیده
Proteinase inhibitors (PIs) are anti-metabolic proteins, which interfere with the digestive process of insects. It is one of the important defence strategies existing in plants against predators. The use of the plant-derived PI genes for developing insect-resistant transgenic crops has come of age. Several transgenic plants expressing PIs have been created and these plants have shown enhanced resistance against insect pests. Recently PIs have also been used to engineer resistance against viruses in transgenic plants. The current scenario for developing insect, fungal and viral pathogen-resistant transgenic crops by using PI gene(s) is reviewed. The biosafety aspect of the transgenic plants expressing PIs is also discussed.

Plant Insecticidal Proteins and their Potential for Developing Transgenics Resistant to Insect Pests
Insects cause heavy damage to cultivated crop plants. Production of proteinaceous inhibitors that interfere with the digestive biochemistry of insect pests is one of the naturally occurring defence mechanisms in plants. These proteins include lectins, arcelins and inhibitors of alpha amylases and proteases of various larvae pests. Use of plant genes encoding effective inhibitors of major digest...
متن کاملOverexpression of a Weed (Solanum americanum) Proteinase Inhibitor in Transgenic Tobacco Results in Increased Glandular Trichome Density and Enhanced Resistance to Helicoverpa armigera and Spodoptera litura
In this study we produced transgenic tobacco plants by overexpressing a serine proteinase inhibitor gene, SaPIN2a, from the American black nightshade Solanum americanum under the control of the CaMV 35S promoter using Agrobacterium tumefaciens-mediated transformation. SaPIN2a was properly transcribed and translated as indicated by Northern blot and Western blot analyses. Functional integrity of...
متن کاملPest Protection Conferred by a Beta vulgaris Serine Proteinase Inhibitor Gene
Proteinase inhibitors provide a means of engineering plant resistance to insect pests. A Beta vulgaris serine proteinase inhibitor gene (BvSTI) was fused to the constitutive CaMV35S promoter for over-expression in Nicotiana benthamiana plants to study its effect on lepidopteran insect pests. Independently derived BvSTI transgenic tobacco T2 homozygous progeny were shown to have relatively high ...
متن کاملFunctional proteomics-aided selection of protease inhibitors for herbivore insect control
Studies have reported the potential of protease inhibitors to engineer insect resistance in transgenic plants but the general usefulness of this approach in crop protection still remains to be established. Insects have evolved strategies to cope with dietary protease inhibitors, such as the use of proteases recalcitrant to inhibition, that often make the selection of effective inhibitors very c...
متن کاملTransformation And Light Inducible Expression of cry1Ab Gene in Oilseed Rape (Brassica napus L.)
Rapeseed (Brassica napus L.) is the third most important oil crop in global productions. One of the major limiting factors for oilseed rape production is lepidopteran pests of the Brassicaceae family. Transgenic plants expressing Bacillus thuringiensis (Bt) genes are powerful tools in the integrated pest management of crop plants. In the present study, we used a synthetic Bt insecticidal crysta...
