Functional characterization of intron 1 sequences of DAO1. a Alignment of the conserved DNA motifs in DAO1 intron 1 of Rhodospordium and Rhodotorula species. b Nucleotide sequence logos of the DNA motifs shown above. Rt3 R. toruloides MTCC 457, Rt4 R. toruloides NP11, Rg2 R. glutinis ATCC 204091, Rg3 R. graminis WP1. c Sequences of various IES1 mutants used in PDAO1-in1m2~9. Translational start site and IES1 motif are underlined. d, e Relative strength of DAO1 promoter mutants shown in c
