Expression of cecropin P1 gene increases resistance of Camelina sativa (L.) plants to microbial phytopathogenes

Abstract

Transgenic plants of camelina (Camelina sativa (L.) Crantz) with the synthetic gene of antimicrobial peptide cecropin P1 (cecP1) were obtained. Agrobacterium-mediated transformation is performed using the binary vector pGA482::cecP1 by vacuum infiltration of flower buds. The presence of the cecP1 gene in the genome of plants was confirmed by PCR. CecP1 gene expression in transgenic plants was shown by Western blot analysis and by antimicrobial activity of plant extracts against the bacterial phytopathogene Erwinia carotovora. The plants of F0 and F1 generations had the normal phenotype and retained the ability to form viable seeds in self-pollination. cecP1 plants exhibit enhanced resistance to bacterial and fungal phytopathogens: Erwinia carotovora and Fusarium sporotrichioides. The increased sustainability of cecropin P1-expressing plants against salt stress is shown. The possibility of the integration of the cecP1 gene into the overall protective system of plants against biotic and abiotic stresses is discussed.
