Application 889/KOL/2005 published 2006-08-04, filed 2005-09-28
The global crop productivity has suffered from attack of several pests of which homopteran insects cause a major damage to rice, mustard, tobacco, cotton and chickpea. The present invention attempts to protect the crop loss by affecting the target pests, white fly and cotton aphid with the help of mannose binding insecticidal lectins from leaves of Allium sativum ( garlic). The lectin has undernoted protein sequence marnlltnge glyagqsldv eqykfimqdd cnlvlyeyst piwasntgvt gkngcravmq rdgnfvvydv ngrpvwasns vrgngnyilv lqkdrnvviy gsdiwstgtl lehrvptsfy. The above lectin has been expressed in rice, mustard and chickpea. The transgenic plants have also shown pronounced antagonistic effects against green leafhopper of rice, mustard aphid Chickpea aphids. The present invention also relates to a process for isolation of pure lectin from leaves of Allium sativum which is a rather cost effective one. (FIG.1,2).
