Expression analysis of defense-related genes in wild kiwifruit (Actinidia rufa) tolerant to bacterial canker

Kiwifruit bacterial canker, which is caused by Pseudomonas syringae pv. actinidiae biovar 3 (Psa3), is found throughout kiwifruit-growing countries. Here, we investigated the expression levels of defense-related genes in Actinidia rufa , which is highly tolerant to Psa3. The expression of selected d...

Summary:Kiwifruit bacterial canker, which is caused by Pseudomonas syringae pv. actinidiae biovar 3 (Psa3), is found throughout kiwifruit-growing countries. Here, we investigated the expression levels of defense-related genes in Actinidia rufa , which is highly tolerant to Psa3. The expression of selected defense-related genes tended to be upregulated in typical growth conditions in A. rufa . Lignin content was also significantly higher in A. rufa than in A. chinensis , which is highly susceptible to Psa3. These results suggest that the high tolerance of A. rufa to Psa3 may be caused by the upregulation of defense-related genes and physical resistance.
