Effects of temperature shifts on the Rp1-D21 phenotype. (A) Mutant plants from the cross TX303 × Rp1-D21-H95 showed a dramatic phenotypic change from minor lesions (upper leaf) to more severe lesions (lower leaf) 48 hours after moving from 30/26°C to 22/18°C. (B) Mutant plants from the cross M37W ×Rp1-D21-H95 showed no lesions after three weeks growth at 34/30°C (upper picture). The lower picture shows the identical leaf 48 hours after changing the temperature to 22/18°C. (C and D) The point at which the growing leaf emerged from the main stalk was marked on a leaf of a mutant plants from the cross M37W ×Rp1-D21-H95 (C) and B97 ×Rp1-D21-H95 (D) growing at 22/18°C (upper picture). The temperature was then increased to 34/30°C. The lower picture shows the identical leaf seven days later.
