“…Among eSSRs distorted loci, 43.28% were G. arboreum derived eSSR loci, 17.91% were G. hirsutum derived eSSR loci, and 8.95% were G. raimondii derived eSSR loci. Several factors could cause segregation distortion: redundant heterozygote, mutation of the SSR binding site, which causes the irregular segregation distortion; hitch hiking, gametophyte selection, genetic drift, or cytological attributes pollen tube competition, pollen lethal, preferential fertilization, and zygotic selection all cause the cluster of segregation distortion (Liedl and Anderson 1993; Shappley et al 1998; Sibove et al 2003).…”

This study introduces the construction of the first intraspecific genetic linkage map of the A-genome diploid cotton with newly developed simple sequence repeat (SSR) markers using 189 F(2) plants derived from the cross of two Asiatic cotton cultivars (Gossypium arboreum L.) Jianglingzhongmian x Zhejiangxiaoshanlüshu. Polymorphisms between the two parents were detected using 6 092 pairs of SSR primers. Two-hundred and sixty-eight pairs of SSR primers with better polymorphisms were picked out to analyze the F(2) population. In total, 320 polymorphic bands were generated and used to construct a linkage map with JoinMap3.0. Two-hundred and sixty-seven loci, including three phenotypic traits were mapped at a logarithms of odds ratio (LOD) > or = 3.0 on 13 linkage groups. The total length of the map was 2 508.71 cM, and the average distance between adjacent markers was 9.40 cM. Chromosome assignments were according to the association of linkages with our backbone tetraploid specific map using the 89 similar SSR loci. Comparisons among the 13 suites of orthologous linkage groups revealed that the A-genome chromosomes are largely collinear with the A(t) and D(t) sub-genome chromosomes. Chromosomes associated with inversions suggested that allopolyploidization was accompanied by homologous chromosomal rearrangement. The inter-chromosomal duplicated loci supply molecular evidence that the A-genome diploid Asiatic cotton is paleopolyploid.

“…In this respect, accession MEL1 has proved as the best one for interspecific hybridization. This suggests that this accession could be used as a recurrent parent for introgression breeding in eggplant or for acting as a bridge for introgression in other S. melongena materials (Liedl and Anderson, 1993).…”

Wild relatives represent a source of variation for many traits of interest for eggplant (Solanum melongena) breeding, as well as for broadening the genetic base of this crop. However, interspecific hybridization with wild relatives has been barely used in eggplant breeding programs. As initiation of an introgression breeding program we performed 1424 interspecific hybridizations between six accessions of eggplant from the Occidental and Oriental groups and 19 accessions of 12 wild species from the primary (Solanum incanum and Solanum insanum), secondary (Solanum anguivi, Solanum dasyphyllum, Solanum lichtensteinii, Solanum linnaeanum, Solanum pyracanthos, Solanum tomentosum, and Solanum violaceum), and tertiary (Solanum elaeagnifolium, Solanum sisymbriifolium, and Solanum torvum) genepools. Fruit set, hybrid seed, and seed germination were obtained between Solanum melongena and all wild species of the primary and secondary genepools. The highest fruit set percentage and quantity of seeds per fruit were obtained with the two primary genepool species S. incanum and S. insanum as well as with some secondary genepool species, like S. anguivi, S. dasyphyllum, or S. lichtensteinii, although some differences among species were observed depending on the direction of the hybridization. For small-fruited wild species, the number of seeds per fruit was lower when using them as maternal parent. Regarding tertiary genepool species, fruit set was obtained only in interspecific hybridizations of eggplant with S. sisymbriifolium and S. torvum, although the fruit of the former were parthenocarpic. However, it was possible to rescue viable interspecific hybrids with S. torvum. In total we obtained 58 interspecific hybrid combinations (excluding reciprocals) between eggplant and wild relatives. Some differences were observed among S. melongena accessions in the degree of success of interspecific hybridization, so that the number of hybrid combinations obtained for each accession ranged between 7 (MEL2) and 16 (MEL1). Hybridity of putative interspecific hybrid plantlets was confirmed with a morphological trait (leaf prickliness) and 12 single nucleotide polymorphism markers. The results show that eggplant is amenable to interspecific hybridization with a large number of wild species, including tertiary genepool materials. These hybrid materials are the starting point for introgression breeding in eggplant and in some cases might also be useful as rootstocks for eggplant grafting.

“…Pollen–pistil interactions play a critical role in controlling fertilization from compatible pollen sources and preventing fertilization from incompatible pollen sources (Kikuchi et al ., ; Lee et al ., ; Figueroa‐Castro and Holtsford, ). Inter‐specific pollen–pistil barriers may drive speciation events or form as a consequence of speciation and genetic divergence (Rieseberg and Willis, ; Liedl and Anderson, ). This study focuses on elucidating pollen–pistil barriers in the transmitting tract (TT) of the Nicotiana tabacum pistil.…”

“…Inter‐specific pollen–pistil barriers are the result of either incongruity or incompatibility. Incongruity is defined as a passively evolved mismatch of genetic information between two species (Hogenboom, ; Liedl and Anderson, ; Kuboyama et al ., ), and interspecific incompatibility (II) is an active rejection of interspecific pollen (Liedl and Anderson, ; McClure et al ., ). When II is associated with SI, where SI females reject pollen from self‐compatible males and the reciprocal cross is compatible, it is termed unilateral incompatibility (Pandey, ; Lewis and Crowe, ; de Nattancourt, ; Bedinger et al ., ).…”

PELPIII: the class III pistil‐specific extensin‐like Nicotiana tabacum proteins are essential for interspecific incompatibility

SUMMARYPre-zygotic interspecific incompatibility (II) involves an active inhibition mechanism between the pollen of one species and the pistil of another. As a barrier to fertilization, II effectively prevents hybridization and maintains species identity. Transgenic ablation of the mature transmitting tract (TT) in Nicotiana tabacum resulted in the loss of inhibition of pollen tube growth in Nicotiana obtusifolia (synonym Nicotiana trigonophylla) and Nicotiana repanda. The role of the TT in the II interaction between N. tabacum and N. obtusifolia was characterized by evaluating N. obtusifolia pollen tube growth in normal and TT-ablated N. tabacum styles at various post-pollination times and developmental stages. The II activity of the TT slowed and then arrested N. obtusifolia pollen tube growth, and was developmentally synchronized. We hypothesize that proteins produced by the mature TT and secreted into the extracellular matrix inhibit interspecific pollen tubes. When extracts from the mature TT of N. tabacum were injected into the TT-ablated style prior to pollination, the growth of incompatible pollen tubes of N. obtusifolia and N. repanda was inhibited. The class III pistil-specific extensin-like protein (PELPIII) was consistently associated with specific inhibition of pollen tubes, and its requirement for II was confirmed through use of plants with antisense suppression of PELPIII. Inhibition of N. obtusifolia and N. repanda pollen tube growth required accumulation of PELPIII in the TT of N. tabacum, supporting PELPIII function in pre-zygotic II.
