ENY2 and infection: To summarize, Sl-SUS1 and Sl-SUS3 were activated upon infection and the early activation of these genes, as well as those that encode cell wall invertases, was associated with reduced susceptibility, while on the contrary the early repression of Sl-SUS4 to Sl-SUS7 and cell wall invertases, except for Sl-LIN6, was associated with increased susceptibility.
