In incompatible pollen, PbrGNAT1 acetylates PbrPPA5, where it interacts with PbrbZIP77 at the PbrPME44 ABRE motif, causing reduced PbrPME44 expression and pollen tube tip swelling. PbrPME44 transcription leads to unaltered pollen tube tips in compatible pollen tubes. Modified from Tang et al (2023) Figure 9.
