Cover Caption: INS localizes to the cytosol of Arabidopsis cells
Higher plants have been proposed to have two IAA biosynthetic pathways: one is tryptophan-dependent and another is tryptophan-independent. In this issue, Zhang et al. (pages 1070–1077) reported the isolation and characterization of the Arabidopsis indole synthase (INS), a homolog of Trp synthase α (TSA1). Their results demonstrated that INS is different from TSA1 in the expression pattern, the subcellular localization and the functional complementation of E. coli trpA cells, implying that INS may participate in a non-tryptophan biosynthetic pathway (Cover design: Ying Wang).
