Figure 1.11 Relative gene expression profiles of PaChi4, a elass IV chitinase, and pathogen colonization levels in bark of two Norway spruce clones following inoculation with Heterobasidion annosum. The bark around the inoculation site was spatially sampled 3 and 14 days after inoculation. Clone 409 is highly susceptible and clone 589 is moderately resistant to this pathogen. The transcript levels of the chitinase in clone 409 at the time of inoculation (shown at 0 mm distance from inoculation) were used as a reference transcript level and defined as the lx expression level, and the transcript levels of all the other samples are expressed as the fold change over this reference level. Pathogen colonization (Path, col.) was measured as the ratio of pathogen to host DNA. Each data point represents the mean of two ramets. For further details, see Hietala et al. (2004).

The relationship between chitinolytic gene expression and extracellular chitinase activity in individual cells of the marine bacterium Pseudoalteromonas s, strain S91 attached to solid chitin were evaluated likewise, the mutation of active site residues in the chitin-binding domain ChBD(ChiAl) of chitinase Al of Bacillus circulans was found to alter the substrate specificity (Baty et al., 2000 Hardt Laine, 2004). Escherichia co7 expressing recombinant green fluorescent protein was used to test the bactericidal efficacy of a newly synthesized chitosan-Ag nanoparticles that had significantly higher antimicrobial activity than the components at their respective concentrations (Sanpui et al., 2008).
