TL;DR: In this article, the TAA family produces indole-3-pyruvic acid (IPA) and the YUC family functions in the conversion of IPA to IAA in Arabidopsis.

TL;DR: The genetic data show that Y UC and TAA work in the same pathway and that YUC is downstream of TAA, indicating that TAAs are responsible for converting tryptophan to IPA, whereas YUCs play an important role in converting IPA to indole-3-acetic acid.

TL;DR: In this paper, the authors examined whether importing intermediate goods improves plant performance and found evidence that becoming an importer of foreign intermediates improves productivity, while addressing the issue of simultaneous productivity shocks and decisions to import intermediates.

TL;DR: In this article, the authors developed an open economy model with heterogeneous final goods producers who simultaneously choose whether to export their goods and whether to use imported intermediates, highlighting mechanisms whereby import policies affect aggregate productivity, resource allocation, and industry export activity along both the extensive and intensive margins.

TL;DR: In this paper, an open economy model with heterogeneous final goods producers who simultaneously choose whether to export their output and whether to use imported intermediates is developed and estimate a structural empirical model that incorporates heterogeneity in productivity, transport costs, and other costs using Chilean plant-level data for a set of manufacturing industries.
