Abstract Improving lint percentage (LP) is a key breeding target for Sea Island cotton (Gossypium barbadense), yet its genetic basis remains poorly understood. Here, we identify GbNAC072C as a positive regulator of LP that promotes fiber cell protrusions by directly activating the transcription of GbHOX3. We find that GbNAC072C is inhibited by GbDEAH12G, and crucially, the strength of this interaction is haplotype-dependent.

Abstract 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 F1 hybrids, revealing genome-wide (~15%) and often compensatory cis and trans regulatory changes under divergence and domestication.
