Summary: | Cis
and
trans
regulatory divergence underlies phenotypic and evolutionary diversification. Relatively little is understood about the complexity of regulatory evolution accompanying crop domestication, particularly for polyploid plants. Here, we compare the fiber transcriptomes between wild and domesticated cotton (
Gossypium hirsutum
) and their reciprocal F
1
hybrids, revealing genome-wide (~15%) and often compensatory
cis
and
trans
regulatory changes under divergence and domestication. The high level of
trans
evolution (54%–64%) observed is likely enabled by genomic redundancy following polyploidy. Our results reveal that regulatory variation is significantly associated with sequence evolution, inheritance of parental expression patterns, co-expression gene network properties, and genomic loci responsible for domestication traits. With respect to regulatory evolution, the two subgenomes of allotetraploid cotton are often uncoupled. Overall, our work underscores the complexity of regulatory evolution during fiber domestication and may facilitate new approaches for improving cotton and other polyploid plants.
Relatively little is known about the complexity of regulatory evolution accompanying polyploid crop domestication. Here, using reciprocal hybrids between wild and domesticated allotetraploid cotton lines, the authors catalog
cis
and
trans
regulatory variants and show their equivalent effects on cotton fiber domestication. |
