-A rice gain-of-function mutant, ''Osiaa13'', contains a single amino acid substitution (G to A, which resulted in a single amino acid substitution, glycine (G) to serine (S), in the core sequence in domain II of OsIAA13 required for the degradation of the OsIAA13 protein). The ''Osiaa13'' mutant displayed typical auxin-related phenotypes: the number of lateral roots was significantly reduced and the root gravitropic response was defective. Osiaa13 mutants also exhibited altered GUS staining controlled by the DR5 promoter in lateral root initiation sites. Furthermore, expression levels of several genes that might be associated with lateral root initiation were altered in ''Osiaa13''[1].

-Please input evolution information here.
+OsIAA13 shares high sequence similarity with OsIAA11 and OsIAA30 in rice, and with AXR2/IAA7, SLR/IAA14, IAA16, and AXR3/IAA17 in ''Arabidopsis''[2]. It has been reported that lateral root initiation is inhibited in a ''SLR/IAA14'' gain-of-function mutant, and in ''ARF7'' and ''ARF19'' loss-of-function mutants; the latter proteins interact with IAA14/SLR[3,4,5]. The gain-of-function mutant ''Osiaa11'' showed a similar phenotype to ''Osiaa13'': the lateral root number of Osiaa11 was reduced because of a defect in LRP initiation but the crown root number was not reduced [6]. Examination of the RiceXPro database revealed that ''OsIAA13'', ''OsIAA11'', and ''OsIAA30'' show similar gene expression patterns indicating that the function of OsIAA30 might be redundant with OsIAA13 and OsIAA11 in lateral root initiation. Taken together, ''OsIAA13'', ''OsIAA11'', and ''OsIAA30'' may play an important role in lateral root formation but not in crown root formation.
