Multiple sequence alignment of Aux/IAA genes in B. napus. Four conserved domains are indicated with black boxes. LxLxLx and GWPPv/i motifs in domain I and II are highlighted with black lines. The second LxLxLx motif between domain I and II is indicated with red boxes. NLSs and βαα motif are represented by black solid rectangles. The PB1 domain features of a conserved lysine and the OPCA-like motif phosphorylation sites are emphasized by black arrows (Korasick et al., Proc Natl Acad Sci USA, 2014(111): 5427–5432). (PDF 9716 kb
