Cotton supplies a great majority of natural fiber for the global textile industry. The negative correlation between yield and quality has hindered breeders' ability to improve these traits simultaneously. A multi-parent advanced generation inter-cross (MAGIC) population developed through random-mating multiple diverse parents break this correlation. Genotyping-by-sequencing (GBS) is method that can rapidly identify genotype large number single nucleotide polymorphisms (SNP). Genotyping MAGIC...
The cotton fibre serves as a valuable experimental system to study cell wall synthesis in plants, but our understanding of the genetic regulation this process during development remains limited. We performed genome-wide association (GWAS) and identified 28 loci associated with quality allotetraploid cotton. To investigate regulatory roles these loci, we sequenced transcriptomes 251 accessions 15 330 expression quantitative trait (eQTL). Analysis local eQTL GWAS data prioritised 13 likely...
The superior fiber properties of Gossypium barbadense L. serve as a source novel variation for improving quality in Upland cotton ( G. hirsutum L.), but introgression from has been largely unsuccessful due to hybrid breakdown and lack genetic genomic resources. In an effort overcome these limitations, we constructed linkage map conducted quantitative trait locus (QTL) analysis 10 agronomic traits recombinant inbred mapping population derived cross between TM‐1, line, NM24016, elite line with...
Our objective was to test whether or not plastids and mitochondria, the two DNA-containing organelles, move between cells in plants. As our experimental approach, we grafted different species of tobacco, Nicotiana tabacum sylvestris. Grafting triggers formation new cell-to-cell contacts, creating an opportunity detect organelle movement genetically distinct We initiated tissue culture from sliced graft junctions selected for clonal lines which gentamycin resistance encoded N. nucleus...
Individual fiber strength is an important quality attribute that greatly influences the of yarn spun from cotton fibers. Fiber usually measured bundles fibers due to difficulty reliably measuring individual However, bundle (BFS) not always correlated with since it affected by multiple properties involved in fiber-to-fiber interactions within a addition strength. Molecular mechanisms responsible for regulating remain unknown. Gossypium hirsutum near isogenic lines (NILs), MD52ne and MD90ne...
Naturally colored cotton (NCC) offers an environmentally friendly fiber for textile applications. Processing white into textiles requires extensive energy, water, and chemicals, whereas processing of NCC skips the most polluting activity, scouring-bleaching dyeing; therefore, provides avenue to minimize harmful impacts production. varieties are suitable organic agriculture since they naturally insect disease-resistant, salt drought-tolerant. Various shades, ranging from light green tan...
The presence of two closely related subgenomes in the allotetraploid Upland cotton, combined with a narrow genetic base cultivated varieties, has hindered identification polymorphic markers and their use improving this important crop. Genotyping-by-sequencing (GBS) is rapid way to identify single nucleotide polymorphism (SNP) markers; however, these SNPs may be specific sequenced cotton lines. Our objective was obtain large set broad applicability germplasm. We selected 11 diverse cultivars...
Abstract Background Cotton fiber length is very important to the quality of textiles. Understanding genetics and physiology cotton elongation can provide valuable tools industry by targeting genes or other molecules responsible for elongation. Ligon Lintless-1 ( Li 1 ) a monogenic mutant in Upland Gossypium hirsutum which exhibits an early cessation resulting short fibers (< 6 mm) at maturity. This presents excellent model system studying underlying molecular cellular processes involved...
Some naturally coloured brown cotton fibres from accessions of Gossypium hirsutum L. can be used to make textiles with enhanced flame retardancy (FR). Several independent fibre loci have been identified and mapped chromosomes, but the underlying genes not yet identified, mechanism lint FR is fully understood. In this study, we show that both colour Lc1 locus are linked a 1.4Mb inversion on chromosome A07 immediately upstream gene similarity Arabidopsis TRANSPARENT TESTA 2 (TT2). As result...
Actin polymerizes to form part of the cytoskeleton and organize polar growth in all eukaryotic cells. Species with numerous actin genes are especially useful for dissection molecular function due redundancy neofunctionalization. Here, we investigated role a cotton (Gossypium hirsutum) gene organization filaments lobed cotyledon pavement cells highly elongated single-celled trichomes that comprise lint fibers. Using mapping-by-sequencing, virus-induced silencing, modeling, identified...
Abstract Cotton ( Gossypium hirsutum L.) fiber is the most important resource of natural and renewable for textile industry. However, understanding genetic components their genome-wide interactions controlling quality remains fragmentary. Here, we sequenced a multiple-parent advanced-generation inter-cross (MAGIC) population, consisting 550 individuals created by inter-crossing 11 founders, established mosaic genome map through tracing origin haplotypes that share identity-by-descent (IBD)....
Transforming growth factor beta (TGF-beta) plays critical roles in the control of cell proliferation, differentiation, and apoptosis. Smad proteins are substrates TGF-beta type I receptor responsible for transducing signals to target genes nucleus. The PIAS (protein inhibitor activated STAT) were originally identified as transcriptional co-regulators JAK-STAT pathway. Subsequently, cross-talk between other signaling pathways has been shown be involved various cellular processes. Importantly,...
Beta-catenin plays multiple roles in cell-cell adhesion and Wnt signal transduction. Through the signal, cellular level of beta-catenin is constitutively regulated by multicomponent destruction complex containing glycogen synthase kinase 3beta, axin, adenomatous polyposis coli. Here, we present lines evidence to demonstrate that LZTS2 (lucine zipper tumor suppressor 2) interacts with beta-catenin, represses transactivation affects subcellular localization beta-catenin. The gene located at...
Improving cotton fiber length without reducing yield is one of the major goals breeding. However, genetic improvement by breeding has been a challenge due to narrow diversity modern cultivars and negative correlations between quality traits. A multi-parent advanced generation inter-cross (MAGIC) population developed through random mating provides an excellent resource that allows quantitative trait loci (QTL) causal genes be identified. An Upland MAGIC population, consisting 550 recombinant...
Naturally-colored brown cotton (NBC) fiber is an environmentally friendly raw source of for textile applications. The some NBC cultivars exhibits flame-retardant properties, which can be used in textiles that require flame resistance. Proanthocyanidins or their derivatives are responsible the pigment NBC; however, how retardancy related to pigmentation poorly understood. To gain insight into biosynthesis, we conducted comparative transcripts and metabolites profiling analysis developing...
The number of cotton (Gossypium sp.) ovule epidermal cells differentiating into fiber initials is an important factor affecting yield and quality. Despite extensive efforts in determining the molecular mechanisms regulating initial differentiation, only a few genes responsible for differentiation have been discovered. To identify putative directly involved initiation process, we used culture technique that controls timing by exogenous phytohormone application combination with comparative...
