Figure 5: P provision affects HRS1 and NRT1.1 protein stability.
From: AtNIGT1/HRS1 integrates nitrate and phosphate signals at the Arabidopsis root tip
(a) CHX (100 μM) treatment affects HRS1–GFP accumulation differentially in +P and –P conditions. (b) Quantification of immunoblot signal. (c) P starvation accelerates the protein degradation rate of the nitrate transporter/sensor NRT1.1, but not the aquaporin PIP2.1 (used as non-nitrate-inducible control).
