Abstract
The changes in ubiquitin mRNA level in intact plants of both susceptib le (cv, Spunta) and partially resistant (cv. Pampeana-INTA) potato cul tivars after inoculation with low doses (10(3) sporangia cm(-3)) of Ph ytophthora infestans were studied after 72 h of treatment. inoculation leads to 5-fold accumulation of potato ubiquitin transcripts in both cultivars. This result supports the connection between ubiquitin expre ssion and defense reaction in plants.
