Abstract
Chromosome painting is one of the key technologies in cytogenetic research, which can accurately identify chromosomes or chromosome regions. Oligonucleotide (oligo) probes designed based on genome sequences have both flexibility and specificity, which would be ideal probes for fluorescence in situ hybridization (FISH) analysis of genome structure. In this study, the bulked oligos of the two arms of chromosome seven of cotton were developed based on the genome sequence of Gossypium raimondii (DD, 2n = 2× = 26), and each arm contains 12,544 oligos. Chromosome seven was easily identified in both D genome and AD genome cotton species using the bulked chromosome-specific painting probes. Together with 45S ribosomal DNA (rDNA) probe, the chromosome-specific painting probe was also successfully used to correct the chromosomal localization of 45S rDNA in G. raimondii. The study reveals that bulked oligos specific to a chromosome is a useful tool for chromosome painting in cotton.

Abstract
A bacterial artificial chromosome (BAC) library for G. mustelinum Miers ex G. Watt (AD4) was constructed. Intact nuclei from G. mustelinum (AD4) were used to isolate high molecular weight DNA, which was partially cleaved with Hind III and cloned into pSMART BAC (Hind III) vectors. The BAC library consisted of 208,182 clones arrayed in 542 384-microtiter plates, with an average insert size of 121.72 kb ranging from 100 to 150 kb. About 2% of the clones did not contain inserts. Based on an estimated genome size of 2372 Mb for G. mustelinum, the BAC library was estimated to have a total coverage of 10.50 × genome equivalents. The high capacity library of G. mustelinum will serve as a giant gene resource for map-based cloning of quantitative trait loci or genes associated with important agronomic traits or resistance to Verticillium wilt, physical mapping and comparative genome analysis.

Abstract
This study reports transmission genetics of chromosomal segments into Gossypium hirsutum from its most distant euploid relative, Gossypium mustelinum . Mutilocus interactions and structural rearrangements affect introgression and segregation of donor chromatin. Wild allotetraploid relatives of cotton are a rich source of genetic diversity that can be used in genetic improvement, but linkage drag and non-Mendelian transmission genetics are prevalent in interspecific crosses. These problems necessitate knowledge of transmission patterns of chromatin from wild donor species in cultivated recipient species. From an interspecific cross, Gossypium hirsutum × Gossypium mustelinum, we studied G. mustelinum (the most distant tetraploid relative of Upland cotton) allele retention in 35 BC3F1 plants and segregation patterns in BC3F2 populations totaling 3202 individuals, using 216 DNA marker loci. The average retention of donor alleles across BC3F1 plants was higher than expected and the average frequency of G. mustelinum alleles in BC3F2 segregating families was less than expected. Despite surprisingly high retention of G. mustelinum alleles in BC3F1, 46 genomic regions showed no introgression. Regions on chromosomes 3 and 15 lacking introgression were closely associated with possible small inversions previously reported. Nonlinear two-locus interactions are abundant among loci with single-locus segregation distortion, and among loci originating from one of the two subgenomes. Comparison of the present results with those of prior studies indicates different permeability of Upland cotton for donor chromatin from different allotetraploid relatives. Different contributions of subgenomes to two-locus interactions suggest different fates of subgenomes in the evolution of allotetraploid cottons. Transmission genetics of G. hirsutum × G. mustelinum crosses reveals allelic interactions, constraints on fixation and selection of donor alleles, and challenges with retention of introgressed chromatin for crop improvement.

Mol Phylogenet Evol 2017; 112:268-276. [PMID: 28414099 DOI: 10.1016/j.ympev.2017.04.014] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2016] [Revised: 04/12/2017] [Accepted: 04/12/2017] [Indexed: 01/08/2023]
Abstract
Cotton (Gossypium spp.) is commonly grouped into eight diploid genomic groups, designated A-G and K, and one tetraploid genomic group, namely AD. To gain insight into the phylogeny of Gossypium and molecular evolution of the chloroplast genome duringdiversification, chloroplast genomes (cpDNA) from 6 D-genome and 2 G-genome species of Gossypium (G. armourianum D2-1, G. harknessii D2-2, G. davidsonii D3-d, G. klotzschianum D3-k, G. aridum D4, G. trilobum D8, and G. australe G2, G. nelsonii G3) were newly reported here. In combination with the 26 previously released cpDNA sequences, we performed comparative phylogenetic analyses of 34 Gossypium chloroplast genomes that collectively represent most of the diversity in the genus. Gossypium chloroplasts span a small range in size that is mostly attributable to indels that occur in the large single copy (LSC) region of the genome. Phylogenetic analysis using a concatenation of all genes provides robust support for six major Gossypium clades, largely supporting earlier inferences but also revealing new information on intrageneric relationships. Using Theobroma cacao as an outgroup, diversification of the genus was dated, yielding results that are in accord with previous estimates of divergence times, but also offering new perspectives on the basal, early radiation of all major clades within the genus as well as gaps in the record indicative of extinctions. Like most higher-plant chloroplast genomes, all cotton species exhibit a conserved quadripartite structure, i.e., two large inverted repeats (IR) containing most of the ribosomal RNA genes, and two unique regions, LSC (large single sequence) and SSC (small single sequence). Within Gossypium, the IR-single copy region junctions are both variable and homoplasious among species. Two genes, accD and psaJ, exhibited greater rates of synonymous and non-synonymous substitutions than did other genes. Most genes exhibited Ka/Ks ratios suggestive of neutral evolution, with 8 exceptions distributed among one to several species. This research provides an overview of the molecular evolution of a single, large non-recombining molecular during the diversification of this important genus.
