DRR206 IS ACTIVATED WITH RACE-SPECIFICITY BY BACTERIA
AND FUNGI
The DRR206 gene family encodes a protein
of approx. 20 kDa with no significant similarity to any known protein.

DRR206 is strongly induced by Fusarium oxysporum in seedlings of
near isogenic pea lines Vantage (R) and M410 (S).
Hadwiger et al. (1992) Phys. Mol. Plant Pathol. 40:259-269.
DRR206 genes are most strongly-expressed
against incompatible races of Pseudomonas syringae pv. pisi.

DRR206 is also induced by lipoprotein-peptidoglycan preparations,
or killed cells, from P. syringae in a non-race-specific fashion.
