Monolignol biosynthesis is associated with resistance to Sclerotinia sclerotiorum in Camelina sativa.

ABSTRACT: The ascomycete Sclerotinia sclerotiorum is a necrotrophic plant pathogen with an extremely broad host range. It causes stem rot in Camelina sativa, a crucifer with great potential as an alternative oilseed crop. Lignification is a common phenomenon in the expression of resistance against necrotrophs, but the molecular mechanisms underlying this defence response are poorly understood. We present histochemical, gene expression and biochemical data investigating the role of monolignols in the resistance of C. sativa to S. sclerotiorum. Comparative studies with resistant and susceptible lines of C. sativa revealed substantial differences in constitutive transcript levels and gene regulation patterns for members of the gene family encoding cinnamoyl-CoA reductase (CCR), the first enzyme specifi
