Abstract

Plant disease resistance (R) genes enable plants to detect pathogens and to respond by activating defence mechanisms. Although several R genes have recently been isolated, we know little of how this activation occurs. A direct approach to this problem is to isolate mutations that comprise R gene function and isolate the corresponding genes. We study the tomato Cf-2, 4, 5 and 9 genes that confer resistance to corresponding races of leaf mould (Cladosporium falvum), and have identified rcr (required for Cladosporium resistance) mutations that affect Cf-2 or Cf-9 function. Here, we propose to map and clone the Rcr-3 and Rcr-5 genes. These genes and their products may allow engineering of the plant defence response.
