A LARGE ARRAY OF DEFENSE GENES IS ACTIVATED BY PATHOGENIC ATTACK

2D-protein gels allow us to visualize genes proteins induced in pea during non-host resistance to Fusarium solani f. sp. phaseoli

Wagoner et al. (1982) Phys. Plant Pathol. 20:99-107.

Pea cDNA clones representing fungal-induced mRNAs were identified by differential hybridization using labeled probes derived from mRNAs from inoculated or uninoculated plants.
Riggleman et al. (1985) Plant Mol. Biol. 4:81-86.

Defense genes identified included

  • PR10 - 17 kDa ribonuclease-like protein
  • defensin - 5 kDa Cys-rich antifungal protein
  • DRR206 - 20 kDa protein, unknown function

Timecourses reveal that expression patterns differ  when pea pods are inoculated with compatible or incompatible races of Fusarium solani, chitosan, or water.
