Abstract
It was once proposed that there are only two kinds of biology: elegant genetics and sloppy biochemistry (E.C. Pauling, unpublished). For those who study auxin metabolism in Arabidopsis, this geneticist’s view of the different approaches to biological research has particular resonance. Arabidopsis has the advantage of providing a model molecular genetic system in a plant that uses the indole ring to produce diverse compounds, such as the glucosinolate glucobrassicin, the phytoalexin camalexin and the phytohormone indole-3-acetic acid (IAA). This model plant genetic system offers unique opportunities to apply new approaches to answer long-standing questions regarding auxin. However, studies in Arabidopsis can often present us with confounding problems when it comes to careful dissection of the network of indolic pathways in either normal or mutant plants. In this review, we focus our attention on IAA metabolism in Arabidopsis, However, by necessity we have been obliged to draw complementary information from the literature on other species to delineate as completely as possible the most current views on processes responsible for IAA production and its regulation.
