Other claims from this paper (7)
- Mechanism Proximity labeling, co-immunoprecipitation and fluorescence microscopy in Nicotiana benthamiana indicated a general role of RIN4 in EV secretion.
- Intervention effect Mutation of EXO70E1, EXO70E2 or SCD1 reduced secretion of TET8-, PEN1- and PATL1-marked EVs in Arabidopsis.
- Intervention effect Mutation of RIN4 reduced levels of TET8+ and PEN1+ EVs in Arabidopsis.
- Intervention effect Mutation of RIN4 did not reduce levels of PATL+ EVs in Arabidopsis.
- Intervention effect Mutation of the small GTPase gene RABA2a specifically affected PEN1+ EV secretion in Arabidopsis.
- Intervention effect Mutations in ATG5 and VAP27 specifically affected TET8+ EV secretion in Arabidopsis.
- Association exo70 family mutants were more susceptible to infection with the fungal pathogen Colletotrichum higginsianum.
