Hypothesis
Are there duplicated Hox genes in the spider Cupiennius salei?
Conclusion
The presence of at least three duplicated Hox genes suggests a major duplication event in the lineage to this spider.
Supporting Evidence
- Cupiennius salei is the first chelicerate for which all ten classes of arthropod Hox genes have been described.
- At least three Hox genes in Cupiennius are present as duplicate copies.
- The expression patterns of duplicated Hox genes show differences in their roles.
Takeaway
This study found that the spider Cupiennius salei has multiple copies of certain genes that help determine its body structure.
Methodology
The study involved isolating and analyzing Hox gene sequences and their expression patterns in spider embryos.
Limitations
The study lacks genomic information to confirm the presence of additional duplicated Hox genes.
