“…Gossypium barbadense ( G. barbadense ) and Gossypium hirsutum ( G. hirsutum ) are two major cultivated allopolyploid species, originating from natural hybridization and polyploidization events between diploid A0 and D5 genomes approximately 1–2 million years ago (MYA) 10 . These two cotton species exhibit significant differences in traits, such as stress tolerance, fiber quality, and lint yield 11 . These variations can be attributed to different processes of natural selection and human domestication.…”

Cotton is a significant cash crop and the primary source of natural fiber globally. Among the numerous diseases encountered in cotton production, Verticillium wilt is one of the most serious, caused by the pathogen Verticillium dahliae (V. dahliae). Unfortunately, there are no effective targeted methods to combat this disease. Genomic resources for Verticillium wilt resistance primarily exist in Gossypium barbadense (G. barbadense). Regrettably, there have been limited transcriptomic comparisons between V. dahliae-resistant and -susceptible varieties of G. barbadense due to the scarcity of susceptible resources. In this study, we conducted a transcriptome analysis on both V. dahliae-resistant and -susceptible varieties of G. barbadense at the 0, 12, 24 and 48 hours after V. dahliae inoculation. This comparative transcriptome analysis yielded high-quality data and offered new insights into the molecular mechanisms underlying cotton’s resistance against this destructive pathogen.

“…Cotton ( Gossypium species) is the most widely used natural textile fiber globally, with an estimated value of US $64 billion annually (USDA, 2024). Four cotton species have been domesticated, and among them Gossypium hirsutum is most widely planted because of its high yield and environmental adaptability (Hu et al 2021; Jareczek et al 2023; Viot and Wendel 2023). Cotton fiber trichomes reach about 2.5 to 4 cm in length during 45-50 days post-anthesis (DPA).…”

Cotton fiber length and strength are key determinants of its quality. Dynamic changes in the pectin, xyloglucan, xylan, and cellulose polysaccharide epitopes content during fiber growth contribute to complex remodeling of fiber cell wall (CW) and quality. Detailed knowledge about polysaccharide compositional and structural alteration in the fiber during fiber elongation and strengthening is vastly limited. Here, large-scale glycome profiling coupled with fiber phenotype and transcriptome profiling was conducted on fiber collected daily covering the most critical fiber developmental window. High temporal resolution profiling allowed us to identify specific polysaccharide epitopes associated with distinct fiber phenotypes that might contribute to fiber quality. This study revealed the critical role of highly branched RG-I pectin epitopes such as, β-1,4-linked-galactans, β-1,6-linked-galactans, and arabinogalactans, in addition to earlier reported homogalacturonans and xyloglucans in the formation of cotton-fiber-middle-lamella and contributing to fiber plasticity and elongation. We also propose the essential role of heteroxylans (Xyl-MeGlcA and Xyl-3Ar), as a guiding factor for secondary CW cellulose-microfibril arrangement, thus contributing to fiber strength. Correlation analysis of glycome and transcriptome data identified several key putative glycosyltransferases involved in synthesizing the critical polysaccharide epitopes. Novel details discovered here provide a foundation to identify molecular factors that dictate important fiber traits.

“…Gossypium barbadense L., or Pima cotton, has fibers that are longer and finer than other types of cotton, making it a valuable economic species. G. hirsutum and G. barbadense are allotetraploids (2 n = 4 x = 52) with A and D genomes derived from interspecific hybridization between two diploid species (Viot & Wendel, 2023; Wendel & Cronn, 2003).…”

Cotton bacterial blight (CBB), caused by the pathogen Xanthomonas citri subsp. malvacearum (Xcm), can inflict significant damage to cotton (Gossypium hirsutum L.) production. Previously we identified and mapped the broad‐spectrum CBB resistant locus BB‐13 on the long arm of chromosome D02 using array‐based single nucleotide polymorphisms (SNPs). In the current study, linked SNPs were converted into easily assayable Kompetitive Allele‐Specific PCR (KASP) markers to enable efficient detection and marker assisted selection (MAS) of alleles at the BB‐13 locus. The KASP marker's efficiency in detecting the BB‐13 resistant gene was validated using an Upland cotton diversity panel of 72 accessions phenotyped with Xanthomonas citri subsp. malvacearum (Xcm) race 18. The KASP marker NCBB‐KASP4, derived from the CottonSNP63K array‐based marker i25755Gh that is closely associated with BB‐13, predicted the CBB response phenotypes with an error rate of 4.17% in the diversity panel. Additionally, two independent biparental recombinant inbred line (RIL) populations segregating for resistance to Xcm race 18 were used for KASP marker validation and to test their utility in detecting the presence of the BB‐13 locus in the resistant accession CABD3CABCH‐1‐89. NCBB‐KASP4, validated across breeding populations and broad germplasm, is a reliable KASP marker for detection and testing of BB‐13 locus in cotton. Further, diagnostic array‐based SNP marker i25755Gh's allele pattern and the potential CBB response is described for 875 Gossypium accessions. These SNP based phenotypic predictions for 875 accessions along with disease response phenotypes to Xcm race 18 for 253 accessions provide a reference for CBB resistance in diverse cotton germplasm in the U.S.This article is protected by copyright.
