Local auxin biosynthesis, a major research focus in the field of plant auxin, is spatially and temporally regulated by endogenous developmental signals and environmental cues and therefore plays critical roles in gametogenesis, embryogenesis, organogenesis, tropism, and stress responses in higher plants. In this review, we briefly summarize the interactions between auxin local biosynthesis and apical biosynthesis or polar transport or its homeostasis and highlight the recent progress in understanding the biological functions and regulatory mechanisms of local auxin biosynthesis in higher plants.
