SUMM2 Is Required for Defense Responses Activated by SUMM1.

(A) Morphology of ∼3-week-old SUMM1-FLAG transgenic lines and SUMM1-FLAG expression levels. Line #2 and #3 are two representative SUMMI1-FLAG transgenic lines from the transformation of wild-type plants. Line #4, #5, and #6 are three representative SUMM1-FLAG transgenic lines from the transformation of summ2-8 plants. Rubisco, ribulose-1,5-bis-phosphate carboxylase/oxygenase; WT, the wild type.

(B) and (C) Trypan blue staining (B) and DAB staining (C) of the true leaves of indicated genotypes.

(D) and (E) Expression levels of PR1 (D) and PR2 (E) as determined by quantitative PCR. Values were normalized relative to the expression of ACTIN1. Error bars represent sd of three measurements.
