The use of pathogen-derived effectors as molecular probes to identify S genes is explored, finding that most effector targets identified so far are not applicable as S genes due to detrimental effects they have on other traits.
An effector pair, notably Six5-Avr2, in the fungus Fusarium oxysporum that is recognized by a single resistance gene in tomato, I-2 is identified, the first report of a pair of effectors being recognized by a single R gene.
It is shown that expression of AVR2 is strongly induced in root-and xylem-colonizing hyphae three days post inoculation, and it is found that Avr2 has to be nuclear localized to trigger an I-2 -dependent cell death response.

It is indicated that banana DMR6 functions as a negative regulator of plant immunity and is closely associated with susceptibility to Fusarium wilt, providing a molecular basis for future functional validation and support DMR6 as a potential target for precise genome editing to develop resistant banana cultivars.

Heterologous expression of AVR2 in Arabidopsis thaliana caused enhanced susceptibility towards Verticillium dahliae, a xylem-colonizing fungal pathogen, and in tomato, AVR2 expression resulted in plants with elongated internodes and smaller leaf angles resulting in upward pointing leaves.
It is concluded that future breeding programs will integrate advanced genetic and computational tools to develop rice varieties with durable and broad-spectrum resistance to bacterial leaf streak and other pathogens.
