mos8 suppresses snc1-mediated resistance phenotypes. A, Morphology of 5-week-old soil-grown plants of indicated phenotypes. B, Semiquantitative reverse transcription-PCR of pathogenesis-related genes PR1 and PR2. Fragments were amplified from standardized cDNA in 30 cycles. Actin is included as normalization control. C and D, mos8 suppresses constitutive resistance to virulent bacteria and oomycetes. C, Five-week-old soil-grown plants were infected with P.s.m. ES4326 (OD₆₀₀=0.0001) and quantified at 0 (white bars) and 3 (dark bars) dpi. D, Two-week-old seedlings were inoculated with H.p. Noco2 and conidia were quantified 7 dpi. E, mos8 reduces endogenous SA in snc1 npr1. Total SA was extracted and analyzed with HPLC. Bars represent the average of six (C) and four (D and E) biological replicates, error bars represent sd. All experiments were repeated at least twice with similar results. fw, Fresh weight. [See online article for color version of this figure.]
