Zusammenfassung:	Copyright © 2024 The Authors. Published by Elsevier Masson SAS.. All rights reserved. Cotton is of great economic value because of its fiber that is used in natural textile commodities and its seeds that contain an edible oil with a high content of unsaturated fatty acids and biodiesel applications. Here, we reported that GhKASI_A05 was associated with the cottonseed oil content (SOC) in a natural population via candidate gene association analysis. An 11-bp Indel located in the GhKASI_A05 promoter was found to contribute to SOC and differential expression in upland cotton inbred accessions. Interaction analysis showed that GhWRI1, an AP2/EREBP family transcription factor, that reportedly functions in plant seed oil and fatty acids (FAs) accumulation, directly bound to AW-box cis-elements in two haplotypes of the GhKASI_A05 promoter and activated the expression of GhKASI_A05 at different levels. The seed-specific overexpression of GhKASI_A05 resulted in increased seed size, weight, and protein content, and C16:0 and C18:1 contents but reduced SOC. Our results provide new insights into the biological function of GhKASI in SOC and effective strategies for cotton breeding in the future
