Figure 5From: Analysis of pectin mutants and natural accessions of Arabidopsis highlights the impact of de-methyl-esterified homogalacturonan on tissue saccharificationScatter plot of correlation analysis between enzymatic saccharification efficiency and PAM1 level in Arabidopsis natural accessions. PAM1 epitope levels were determined by immunodot assay (express with respect to 1 μg PGA signal). Enzymatic saccharification efficiency was measured after 24 hours of treatment with 0.5% Celluclast. Pearson correlation analysis revealed a high negative correlation (r = -0.72) between saccharification efficiency and PAM1 content among the accessions analyzed. PGA, polygalacturonic acid.Back to article page
