Sequence Comparison of the 5′ UTR of Arabidopsis NIP5;1, Rice NIP3;1, Maize NIP3;1, and Grape 00000446001.
5′ UTR sequences of At NIP5;1, Os NIP3;1, Zm NIP3;1, and Vv 00000446001 were compared. Two conserved sequences are shown. The nucleotide number corresponds to that from the putative transcription start site (+1). For Os NIP3;1, Zm NIP3;1, and Vv 00000446001, the transcription start site was deduced based on the alignment and sequence identity around the transcriptional start site of the At NIP5;1. Based on the TAIR database, the transcription start site of At NIP5;1 is the first A in AUGUAA; this is also the transcription start site of the rice, maize, and grape genes, and the nucleotides are numbered accordingly. Asterisks indicate conserved sequence among At NIP5;1, Os NIP3;1, Zm NIP3;1, and Vv 00000446001. Short uORFs are underlined.
