Fig. 1: Candidate selection using a three-step filtering strategy.
A Flowchart illustrating the three-step filtering strategy employed to select potential oligosaccharides that accumulate during infection. B Heat map displaying the putative oligogalacturonides (OGs) accumulating over time during the infection. C Heat map showing the non-OG candidates accumulating over time during the infection. Candidates in bold and italic lack elemental compositions compatible with an oligosaccharide structure. PA Peak area, hpi hours post infection, OG oligogalacturonides, CWE cell wall water extract, BcWT B. cinerea wild type strain, GalA galacturonic acid, Me methylester group, Ac acetylester group; OGs are named GalAxMeyAcz. Subscript numbers indicate degree of polymerization and the number of methyl- and acetylester groups, respectively.
