  • The Chinese scientists have recently identified the transfer of genes from plants to insects.
  • Usually transfer of genes happen among the same family.
  • Here the insect called whiteflies has incorporated a portion of DNA from plants into their genome.
  • The incorporated gene found was BtPMaT1.
  • The whiteflies use this gene to neutralise the toxic compounds produced by the plants against them.

Note

  • The transfer of gene from one family to another is referred to as horizontal gene transfer.
