Hypothesis
Do certain genes in domesticated Sorghum bicolor show evidence of non-neutral evolution due to domestication?
Conclusion
The study found strong evidence of non-neutral selection at the starch synthase IIa gene in domesticated sorghum.
Supporting Evidence
- Strong evidence of non-neutral selection was found at the starch synthase IIa gene.
- The starch branching enzyme I and beta kafirin gene showed weaker evidence of non-neutral selection.
- The absence of low frequency variants confounded the detection of consistent signals of non-neutral selection.
Takeaway
Scientists looked at some genes in sorghum to see if they changed because of farming. They found that one gene changed a lot, which helps us understand how we can improve crops.
Methodology
The study sequenced six candidate loci in 35 accessions of Sorghum bicolor to test for non-neutral evolution.
Limitations
The absence of low frequency variants at several candidate genes confounded the detection of consistent signals of non-neutral selection.
Participant Demographics
The study included 35 accessions of Sorghum bicolor from various countries.
