LIF2 is involved in the plant's susceptibility to B. cinerea.

(A-C) Six-week-old plants were infected with a mycelium plug of the virulent B. cinerea B0510 (A-B) and BD90 (C) strains. (A) Symptoms at 3 dpi with the B0510 strain. (B-C) Lesion diameters were measured at 1 to 3 dpi. Stars indicate a significant difference from wild-type leaves on the corresponding day (Mann and Whitney's test, with a p-value of <0.05). (D) Expression of marker genes involved in the defense response to B. cinerea.
