KNSTH1 and KNSTH2 are important for the trafficking of KNS3 from the endoplasmic reticulum to the Golgi. (A, B) mCherry-KNS3 I944A and GFP-HDEL (A) or Man1-GFP (B) in protoplasts from wild-type (WT) (Col-0), knsth1-1, knsth1-2, knsth2-1, and knsth2-3 Arabidopsis leaf mesophyll cells. Scale bars=10 μm. (C, D) Pearson correlation coefficients of mCherry-KNS3 I944A with GFP-HDEL (C) or Man1-GFP (D). Data represent the mean ±SD of 10–17 protoplasts. Asterisks denote significant differences between the WT and the mutant lines (*P<0.01; Dunnett’s test).
