 phylogenetic analysis of multiple An-1 sequences by Luo et al. 2013 showed that nearly all of the cultivars grouped together tightly, which revealed that these cultivars might have originated from a common progenitor in a single domestication event.(Figure 4.)

Upregulation of An-1 expression could induce long awns and grain elongation as well as reduce grain number per panicle in awnless cultivated rice.population genetic analysis of wild and cultivated rice showed a significant reduction in nucleotide diversity of the An-1 locus and revealed that the An-1 locus was a major target for artificial selection<ref name="ref1" />.
