“…was similarly observed for that of G. hirsutum × G. darwinii descendants(Zhang et al 2016). It seems the extra genetic factors may be ascribed to G. hirsutum based on the above two cases and the facts that spotted petals are common in both G. darwinii and G. barbadense species whilst sparse in G. hirsutum cultivars(Zhang et al, 2016;Abid et al, 2022). Accordingly, we crossed G. hirsutum spotted petal lines with non-spotted ones, and all of the F 1 and F 2 lines were more like the current G. arboreum cases that no intermediate petal spots were appeared (data not published).…”

Colored petal spots are correlated with insect pollination e ciency in Gossypium species. However, molecular mechanisms concerning the formation of red spots on Gossypium arboreum owers remain elusive. In the current study, the Shixiya1-R (SxyR, with red spots) × Shixiya1-W (SxyW, without red spots) segregating population was utilized to determine that the red-spot-petal phenotype was levered by a single dominant locus. This phenotype was expectedly related to the anthocyanin metabolites, wherein the cyanidin and delphinidin derivatives constituted the major partition. Subsequently, this dominant locus was narrowed to a 3.27 Mb range on chromosome 7 by genomic resequencing from the two parents and the two segregated progeny bulks that have spotted petals or not. Furthermore, differential expressed genes generated from the two bulks at either of three sequential ower developmental stages that spanning the spot formation were intersected with the annotated ones that allocated to the 3.27 Mb interval, which returned eight genes. A glutathione S-transferase-coding gene (Gar07G08900) out of the eight was the only one that exhibited simultaneously differential expression among all three developmental stages, and it was therefore considered to be the probable candidate. Finally, functional validation upon this candidate was achieved by the appearance of scattered petal spots with inhibited expression of Gar07G08900. In conclusion, the current report identi ed a key gene for the red spotted petal in G. arboretum under the scope of multi-omics approaches, such efforts and embedded molecular resources would bene t future applications underlying the ower color trait in cotton. Key MessageA GST for red-spot-petals in Gossypium arboretum was identi ed as the candidate under the scope of multi-omics approaches.

“…Linkage analysis is an effective tool for identifying genes that control some of the most important morphological changes during domestication and improvement (Doebley et al ., 2006). Over the past decade, many quantitative trait loci (QTLs) related to early maturity traits have been identified (Guo et al ., 2008; Jia et al ., 2016; Kushanov et al ., 2017; Li et al ., 2013a; Li et al ., 2016; Li et al ., 2017; Su et al ., 2016b; Zhang et al ., 2016). To assess whether the sweep regions associated with domestication colocalize with loci known to control early maturity‐related traits, we overlapped selection sweeps with the locations of known QTL hotspots.…”

Although upland cotton (Gossypium hirsutism L.) originated in the tropics, this early maturity cotton can be planted as far north as 46°N in China due to the accumulation of numerous phenotypic and physiological adaptations during domestication. However, how the genome of early maturity cotton has been altered by strong human selection remains largely unknown. Herein, we report a cotton genome variation map generated by the resequencing of 436 cotton accessions. Whole-genome scans for sweep regions identified 357 putative selection sweeps covering 4.94% (112 Mb) of the upland cotton genome, including 5184 genes. These genes were functionally related to flowering time control, hormone catabolism, ageing and defence response adaptations to environmental changes. A genome-wide association study (GWAS) for seven early maturity traits identified 307 significant loci, 22.48% (69) of which overlapped with putative selection sweeps that occurred during the artificial selection of early maturity cotton. Several previously undescribed candidate genes associated with early maturity were identified by GWAS. This study provides insights into the genetic basis of early maturity in upland cotton as well as breeding resources for cotton improvement.

“…Gossypium barbadense is characterized with a purple spot at the base of flower petals (Fryxell, 1984; Zhang et al ., 2016) and petal spots enhance the attractiveness of G. barbadense flowers for insect pollinators, resulting in improved boll‐setting (Jones, 1996). Interestingly, the purple‐colored spot at the base of flower petals is a semidominant trait which is widespread in wild cotton species and often found in landraces of G. hirsutum , but was lost in most modern commercial G. hirsutum cultivars during selection (Zhang et al ., 2016). Here, we show that the Beauty Mark ( GbBM ) gene from G. barbadense , a close allotetraploid relative of G. hirsutum , underlies activation of anthocyanin production, directly leading to formation of a pollinator‐attracting purple spot at the base of flower petals.…”

Hybrid crop varieties have been repeatedly demonstrated to produce significantly higher yields than their parental lines; however, the low efficiency and high cost of hybrid seed production has limited the broad exploitation of heterosis for cotton production. One option for increasing the yield of hybrid seed is to improve pollination efficiency by insect pollinators. Here, we report the molecular cloning and characterization of a semidominant gene, Beauty Mark (BM), which controls purple spot formation at the base of flower petals in the cultivated tetraploid cotton species Gossypium barbadense. BM encodes an R2R3 MYB113 transcription factor, and we demonstrate that GbBM directly targets the promoter of four flavonoid biosynthesis genes to positively regulate petal spot development. Introgression of a GbBM allele into G. hirsutum by marker-assisted selection restored petal spot formation, which significantly increased the frequency of honeybee visits in G. hirsutum. Moreover, field tests confirmed that cotton seed yield was significantly improved in a three-line hybrid production system that incorporated the GbBM allele. Our study thus provides a basis for the potentially broad application of this gene in improving the long-standing problem of low seed production in elite cotton hybrid lines.
