Two draft sequences of Gossypium hirsutum, the most widely cultivated cotton species, provide insights into genome structure, rearrangement, gene evolution and fiber biology. Upland is a model for polyploid crop domestication transgenic improvement. Here we sequenced allotetraploid hirsutum L. acc. TM-1 by integrating whole-genome shotgun reads, bacterial artificial chromosome (BAC)-end genotype-by-sequencing genetic maps. We assembled annotated 32,032 A-subgenome genes 34,402 D-subgenome...
The Gossypium genus is used to investigate emergent consequences of polyploidy in cotton species; comparative genomic analyses reveal a complex evolutionary history including interactions among subgenomes that result genetic novelty elite cottons and provide insight into the evolution spinnable fibres. A phylogenetic study plants provides insights role angiosperm evolution, specifically, emergence fibres domesticated cottons. authors show an abrupt five- sixfold ploidy increase about 60...
Allotetraploid cotton is an economically important natural-fiber-producing crop worldwide. After polyploidization, Gossypium hirsutum L. evolved to produce a higher fiber yield and better survive harsh environments than barbadense, which produces superior-quality fibers. The global genetic molecular bases for these interspecies divergences were unknown. Here we report high-quality de novo–assembled genomes two cultivated allotetraploid species with pronounced improvement in...
Abstract Of the two cultivated species of allopolyploid cotton, Gossypium barbadense produces extra-long fibers for production superior textiles. We sequenced its genome (AD) 2 and performed a comparative analysis. identified three bursts retrotransposons from 20 million years ago (Mya) genome-wide uneven pseudogenization peak at 11–20 Mya, which likely contributed to genomic divergences. Among 2,483 genes preferentially expressed in fiber, cell elongation regulator, PRE1 , is strikingly A t...
Polyploidy is a pervasive evolutionary feature of all flowering plants and some animals, leading to genetic epigenetic changes that affect gene expression morphology. DNA methylation can produce meiotically stable epialleles, which are transmissible through selection breeding. However, the relationship between polyploid plant domestication remains elusive. We report comprehensive epigenomic functional analyses, including ~12 million differentially methylated cytosines in domesticated...
Structural variations (SVs) have long been described as being involved in the origin, adaption, and domestication of species. However, underlying genetic genomic mechanisms are poorly understood. Here, we report a high-quality genome assembly Gossypium barbadense acc. Tanguis, landrace that is closely related to formation extra-long-staple (ELS) cultivated cotton. An SV-based pan-genome (Pan-SV) was then constructed using total 182 593 non-redundant SVs, including 2236 inversions, 97 398...
The mapping of functional genes plays an important role in studies genome structure, function, and evolution, as well allowing gene cloning marker-assisted selection to improve agriculturally traits. Simple sequence repeats (SSRs) developed from expressed tags (ESTs), EST-SSR (eSSR), can be employed putative marker loci easily tag corresponding genes. In this paper, 2218 eSSRs, 1554 G. raimondii-derived 754 hirsutum-derived ESTs, were used screen polymorphisms enhance our backbone genetic...
Abstract Trichomes originate from epidermal cells and can be classified as either glandular or non-glandular. Gossypium species are characterized by the presence of small darkly pigmented lysigenous glands that contain large amounts gossypol. Here, using a dominant glandless mutant, we characterize GoPGF , which encodes basic helix-loop-helix domain-containing transcription factor, propose is positive regulator gland formation. Silencing leads to completely phenotype. A single nucleotide...
Summary Cotton ( Gossypium spp.) is an important economic crop and the largest source of textile fiber in world. However, to date, only a few genes have been identified that exhibit critical roles development, has shown positive effects on yield quality transgenic cotton. Here, we report characterization novel sucrose synthase SusA1 ) gene from superior germplasm line 7235 hirsutum . By association analysis, GhSusA1 was highly correlated with qualities (7235× TM‐1) recombinant inbred lines...
Summary Natural antisense transcripts ( NAT s) are commonly observed in eukaryotic genomes, but only a limited number of such genes have been identified as being involved gene regulation plants. In this research, we investigated the function small RNA derived from fiber cell development. Using map‐based cloning strategy for first time tetraploid cotton, cloned naked seed mutant N 1 ) encoding MYBMIXTA ‐like transcription factor 3 MML )/ Gh MYB 25‐like chromosome A12, 3_A12 , that is...
Cotton, with cellulose-enriched mature fibers, is the largest source of natural textiles. Through a map-based cloning strategy, we isolated an industrially important lint fiber development gene (Li3 ) that encodes MYB-MIXTA-like transcription factor (MML) on chromosome D12 (GhMML4_D12). Virus-induced silencing or decreasing expression GhMML4_D12 in n2 NSM plants resulted significant reduction epidermal cell prominence and production. arranged tandem GhMML3, another MIXTA responsible for fuzz...
Plant cell growth involves a complex interplay among cell-wall expansion, biosynthesis, and, in specific tissues, secondary wall (SCW) deposition, yet the coordination of these processes remains elusive. Cotton fiber cells are developmentally synchronous, highly elongated, and contain nearly pure cellulose when mature. Here, we report that transcription factor GhTCP4 plays an important role balancing cotton elongation synthesis. During development expression miR319 declines while transcript...
Transgenic crops producing insecticidal proteins from the bacterium Bacillus thuringiensis (Bt) are extensively cultivated worldwide. To counter rapidly increasing pest resistance to that produce single Bt toxins, transgenic plant 'pyramids' two or more toxins kill same have been widely adopted. However, cross-resistance and antagonism between limit sustainability of this approach. Here we describe development testing first pyramids cotton combining protection a toxin RNA interference...
Significance Cotton is an important crop, and terpenoids form the largest group of natural products. Gossypol related sesquiterpene aldehydes in cotton function as phytoalexins against pathogens pests but pose human health concerns, oil still widely used vegetable oil. We report isolation identification four enzymes recharacterization one previously reported P450. are now close to completion gossypol pathway, progress agricultural plant sciences, data beneficial improving food safety. Among...
Abstract Background SNPs are the most abundant polymorphism type, and have been explored in many crop genomic studies, including rice maize. SNP discovery allotetraploid cotton genomes has lagged behind that of other crops due to their complexity polyploidy. In this study, genome-wide detected systematically using next-generation sequencing efficient genotyping methods, used construct a linkage map characterize structural variations polyploid genomes. Results We an ultra-dense inter-specific...
Cotton has been cultivated and used to make fabrics for at least 7000 years. Two allotetraploid species of great commercial importance, Gossypium hirsutum barbadense, were domesticated after polyploidization are worldwide. Although the overall genetic diversity between these two studied with limited accessions, their population structure variations remain largely unknown. We resequence genomes 147 cotton including diverse wild relatives, landraces, modern cultivars, construct a comprehensive...
High-throughput genotyping platforms play important roles in plant genomic studies. Cotton (Gossypium spp.) is the world's natural textile fiber and oil crop. Upland cotton accounts for more than 90% of production, however, modern upland cultivars have narrow genetic diversity. The amounts sequencing re-sequencing data released make it possible to develop a high-quality single nucleotide polymorphism (SNP) array intraspecific detection cotton.Here we report high-throughput CottonSNP80K its...
The allotetraploid cotton originated from one hybridization event between an extant progenitor of Gosssypium herbaceum (A1) or G. arboreum (A2) and another progenitor, raimondii Ulbrich (D5) 1-1.5 million years ago (Mya). APETALA2/ethylene-responsive element binding protein (AP2/EREBP) transcription factors constitute the largest most conserved gene families in plants. They are characterized by their AP2 domain, which comprises 60-70 amino acids, classified into four main subfamilies:...
