CSTB and infection: The relevance of CWDEs was previously proved with the appearance of two pectin lyases (pnl1 and pnl2), a polygalacturonase (pg1), a pectin methyl esterase (PME), and three glucanases as predominant genes in the pathogenesis of P. digitatum [18] and in the appearance of different CWDEs genes during the initial infection process of P. digitatum in citrus [27,28].
