Fig. 8. A schematic model for the involvement of MINE/PDX3 in ethylene-induced auxin biosynthesis.

Fig. 8

Anthranilate synthase (ASA and ASB), encoded by WEI2 and WEI7, is a key biosynthesis enzyme for the auxin precursor, Trp. By contrast, TAA1 and its related genes (TARs) are involved in the conversion of Trp to IPyA in the auxin biosynthesis pathway. The MINE gene, which encodes the PNP/PMP oxidase (PDX3) in the PLP salvage pathway, likely plays a role in ethylene-induced auxin biosynthesis.
