Overview

Genome analysis reveals operon co-expression restores crystal formation in Bacillus thuringiensis, highlighting its nematicidal potential.

Key Points

  • Operon-based co-expression restores crystal formation and nematicidal activity comparable to full-length Cry14Aa.
  • Bacillus thuringiensis toxin genes are fragmented yet functionally complementary, enabling natural crystallization.
  • Genome analysis identified two open reading frames related to Cry14Aa1 and Cry21Ca2 targeting nematodes.
  • Study insights pave the way for engineering novel biopesticides using functional recombination of toxin genes.
