17059407 Zhuang X, Jiang J, Li J, Ma Q, Xu Y, Xue Y, Xu Z, Chong K: Over-expression of OsAGAP, an ARF-GAP, interferes with auxin influx, vesicle trafficking and root development. Plant J. 2006 Nov;48(4):581-91. Epub 2006 Oct 19.


In the model dicot plant Arabidopsis thaliana, the trafficking and localization of auxin efflux facilitators such as PIN-FORMED1 (PIN1) are mediated by GNOM, a guanine-nucleotide exchange factor (GEF) for the ADP-ribosylation factor (ARF) family of small GTPases, but molecular regulators of the auxin influx facilitators remain unknown.

The mRNA expression of key enzymes involved in the synthesis, conjugate hydrolysis, accumulation and basipetal transport of auxin, namely indole-3-glycerol-phosphate-synthase, nitrilase, IAA-amino acid hydrolase, chalcone synthase and PIN1 as an essential component of the basipetal IAA carrier, was investigated by reverse transcription-polymerase chain reaction.

Lateral roots growth of CRY1ox could be stimulated by auxin, but expression of PIN1 (efflux carrier of polar auxin transport) was strongly reduced.

The NPA treatment also caused expanded procambium and a broader root apical meristem in embryos, and a significant increase in the expression of a PIN1-like gene.

To study the influence of PINFORMED1 (PIN1)-mediated auxin transport during embryogenesis and endosperm development in monocots, the expression pattern of the three identified ZmPIN1 genes was determined at the transcript level.

The cloning of PIN1, however, provided evidence that this gene encodes a facilitator of auxin efflux, raising the question of how the pin1-1 mutation might reduce overall IAA levels as well as IAA transport.
