25. Differential accumulation of plant defense gene transcripts in a compatible and an incompatible plant-pathogen interaction.
Phenylalanine ammonia-lyase and chalcone synthase catalyze the first reaction of phenylpropanoid biosynthesis and the first reaction of a branch pathway specific for flavonoid-isoflavonoid biosynthesis, respectively. These enzymes are key control elements in the synthesis of kievitone, phaseollin, and related isoflavonoid-derived phytoalexins. RNA blot hybri

26. Differences in Cell Death Induction by Phytophthora Elicitins Are Determined by Signal Components Downstream of MAP Kinase Kinase in Different Species of Nicotiana and Cultivars of Brassica rapa and Raphanus sativus[w]
Elicitins are small, secreted proteins produced by species of the plant-pathogenic oomycete Phytophthora. They induce hypersensitive cell death in most Nicotiana species and in some cultivars of Brassica rapa and Raphanus sativus. In this study, two true-breeding Fast Cycling B. rapa lines were established that showed severe necrosis (line 7-R) or no visible

27. Domain Swapping and Gene Shuffling Identify Sequences Required for Induction of an Avr-Dependent Hypersensitive Response by the Tomato Cf-4 and Cf-9 Proteins
The tomato Cf-4 and Cf-9 genes confer resistance to infection by the biotrophic leaf mold pathogen Cladosporium. Their protein products induce a hypersensitive response (HR) upon recognition of the fungus-encoded Avr4 and Avr9 peptides. Cf-4 and Cf-9 share >91% sequence identity and are distinguished by sequences in their N-terminal domains A and B, their N-
