BAK1 and infection: Although the suppression of FLS2 accumulation in bak1-5 bkk1 mutant after bacterial inoculation was not complete, the infection with P. fluorescens Pf0-1 harboring HopF2Pto-HA for 10 h resulted in increased levels of HopF2Pto-HA and concurrent suppression of FLS2 accumulation, compared to both untransformed P. fluorescens Pf0-1 and P. fluorescens Pf0-1 harboring HopF2Pto(D175A)-HA.
