Figure 4From: The cytosolic thiouridylase CTU2 of Arabidopsis thalianais essential for posttranscriptional thiolation of tRNAs and influences root developmentCTU2 is ubiquitously expressed. CTU2 expression was investigated with a CTU2:GUS fusion construct in transgenic Arabidopsis. Strong GUS activity was observed throughout plant development, in young seedlings (A, B), and rosette leaves (C), siliques/stem (D), flowers (E), and cauline leaves (F).
