| Abstract: | 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 digestive enzymes, such as
protease and a-amylase inhibitors of the target pest species is emerging as
viable approach for the production of pest resistant transgenic crop plants.
Therefore, it is important to characterize proteins and their genes from our
indigenous crops in order to strengthen and broaden our gene bank for pest
control manipulations. The availability of diverse insecticidal proteins and
their genes from different plant species will make it easier to use one or more
genes in combination to develop resistant crop plants. Eventually, insect
resistant transgenic plants will certainly prove more economic than any
conventional control strategy if long-term benefit of transgenic crops
especially factors such as environmental damage and human health risks are
considered. |
