From: Suppression of the auxin response pathway enhances susceptibility to Phytophthora cinnamomi while phosphite-mediated resistance stimulates the auxin signalling pathway

Figure 1

Phytophthora cinnamomi response in several mutants of Arabidopsis thaliana defective in auxin signalling, phosphate signalling and 26S proteasome subunits. Quantitative PCR (QPCR) assessment of Phytophthora cinnamomi biomass (pg DNA per sample) 72 h after inoculation of attached leaves of Arabidopsis thaliana ecotype Colombia (Col-0) and several Arabidopsis mutants defective in Pi signalling (pho1-1, pho2-1, and phr1-1), the auxin signalling pathway (tir1-1and sgt1b-1), and 26S proteasome subunits (pbe1, rpt2a, rpt2b, rpt5a and rpn10). Bars represent the mean and standard error from five replicates each consisting of four infected leaves. One way ANOVA indicated a significant (P < 0.001) difference between genotypes. LSD (5%) was 8.92. phr1-1* = phr1-1 mutant complemented with PHR1 gene (AT4G28610) and tir1-1* = tir1-1 mutant complemented with TIR1gene (AT3G62980).
