The 35Spromoter-driven mDII auxin control sensor is uniformly distributed in leaf primordia.

The DII auxin sensor has been an invaluable tool for mapping the spatiotemporal auxin response and distribution in the model plant Arabidopsis thaliana. The DII sensor and the mDII control sensor are driven by the widely used constitutive 35 S promoter. Recently, however, the reliability of the DII sensor has been questioned(Bhatia et al. 2019). They argued that the 35 S promoter activity is biased toward leaf primordium adaxial side that face the shoot apical meristem (SAM). This article is protected by copyright. All rights reserved.
