Allene oxide synthase (AOS), which acts downstream of LoxD, showed an expression profile in good correlation with that of PinI, being up-regulated in non-infected transgenic plants (2 l2fc), but down-regulated by the viral infections both in BB (-1.9 to -3.3 l2fc) and BBP+ (-1.5 to -2.5 l2fc). This evidence concerns the gene ARHGAP31 and viral infectious disease.
