What is SNORKEL Genes Relating to Flood Tolerance Were Pseudogenized in Normal Cultivated Rice about?
SNORKEL1 (SK1) and SNORKEL2 (SK2) are ethylene responsive factors that regulate the internode elongation of deepwater rice in response to submergence. We previously reported that normal cultivated rice lacks SK genes because the Chromosome 12 region containing SK genes was deleted from its genome. However, no study has analyzed how the genome defect occurred in that region by comparing normal cultivated rice and deepwater rice. In this study, comparison of the sequence of the end of Chromosome 12, which contains SK genes, between normal and deepwater rice showed that complicated genome changes such as insertions, deletions, inversions, substitutions, and translocation occurred frequently in this region. In addition to SK1 and SK2 of deepwater rice, gene prediction analysis identified four genes containing AP2/ERF domains in normal cultivated rice and six in deepwater rice; we called these genes SK-LIKE (SKL) genes. SKs and SKLs were present in close proximity to each other, and the SKLs in normal cultivated rice were in tandem. These predicted genes belong to the same AP2/ERF subfamily and were separated into four types: SK1, SK2, SKL3, and SKL4. Sequence comparison indicated that
