Heat map showing fold-change in gene expression in Actinidia arguta ‘Hortgem Tahi’, Actinidia chinensis var. deliciosa ‘Hayward’ and A. chinensis var. chinensis ‘Zesy002′ kiwifruit plants resulting from application of Ch-Glu (0.125 g/L each of chitosan and laminarin). Gene counts were measured by NanoString PlexSet® with normalization against the reference genes 40s, Actin2, GAPDH and PP2A. Fold-change data in red shades indicate an upregulation relative to the control, whilst blue shades represent downregulation relative to the control, with increasing colour intensity indicating larger fold-changes. Statistically significant differences from the control at individual time points, as determined by LSD (p ≤ 0.05) are identified in bold typeface.
