ABA treatment reduced the expression levels of the PIN-FORMEDs (PIN) auxin efflux carriers, PIN1, PIN3, PIN4, and PIN7, to a greater extent in the root meristems of arf2-101 mutant than in the wild type. ARF2 positively mediates the transcripts of transcription factor PLETHORA 1 (PLT1) gene but negatively mediates PLT2 at protein level in root meristems.

The authors propose that PIN1 expression mediated by cytokinin response factors are required for the determination of pistil size. The greater number of ovule primordia in cytokinin-treated pistils correlates with the increased pistil size. when enough space occurs between two ovules, cytokinin response factors and/or other cytokinin-dependent factors induce PIN1 expression to create a new auxin maximum.

SUB is mis-targeted in hap13-1. However, unlike that of PIN2, the distribution of PIN1 is independent of HAP13. Genetic interference of exocytic trafficking at the TGN/EE by specifically downregulating HAP13 phenocopied the defects of hap13-1 in SUB targeting and ovule development.
