“…A karyomorphological study discussed the hybrid status of Somei-yoshino as a BC 1 progeny backcrossed with C. speciosa or later progenies (Oginuma 1977). Novel classification analysis with 17 SSR markers also suggested a complex origin of Somei-yoshino, where the genome origin was mainly derived from C. spachiana 47 % and C. speciosa 38 % and C. jamasakura 12 % (Kato et al 2014). The origin of Somei-yoshino may be more complicated than previously inferred (Fig.…”

“…Thus, flowering cherry is considered to be a taxa with low reproductive barriers between pollination and fertilization. Although no strict interspecific reproductive barriers are present before fertilization, distinct morphological (Flower Association of Japan 1982; Ohba et al 2007) and genetic (Ohta et al 2005Kato et al 2014) differentiation has been identified for each species. Therefore, both reproductive isolation before pollination and postzygotic reproductive barriers are essential for speciation of cherry species.…”

Cerasus ×yedoensis 'Somei-yoshino' (2n =16), one of the most popular cultivars of Japanese flowering cherry, is considered a hybrid between Cerasus spachiana and Cerasus speciosa. In the present study, we observed segregation of the trait for seedling growth in F 1 progenies of Someiyoshino. In all three families crossed with ancestral wild species, C. spachiana, approximately half of the seedlings showed growth failure. To identify loci involved in seedling inviability, we constructed a genetic linkage map of Someiyoshino. Both normal growth (N=77) and growth failure seedlings (N = 101) of an F 1 progenies crossed between Somei-yoshino (CY) and C. spachiana (E750) were used for map construction. In accordance to pseudo-testcross strategy, female (CY) and male (E750) linkage maps were constructed. The CY map consists of eight linkage groups with 59 simple sequence repeat (SSR) and 17 amplified fragment length polymorphism (AFLP) markers. The map length is 574.9 cM. In contrast, the E750 map reached 196.8 cM and included 17 SSRs. Subsequently, we explored positions of loci associated to seedling inviability along with linkage maps. Results of segregation distortion of markers, association analysis, and interval mapping consistently showed that an inviability gene was located between two SSR markers, EMPaS13 and BPPCT005 in the fourth linkage group (LG4) of the Someiyoshino map with 99.6 % explanations for the inviability trait but not present in LG4 of the E750 map. From the genotypes and expressions of seedling inviability, we named the locus Hybrid Inviability of seedlings 1 (HIs1). Finally, HIs1 was mapped to LG4 as Mendelian trait loci and was completely linked with an SSR, EMPaS13. Although the mechanisms of seedling inviability cannot be explained by only one locus model of HIs1, one of the candidate genes involved in hybrid incompatibility between Somei-yoshino and C. spachiana is certainly located on LG4 of the CY map.

“…It was not, however, until 2014 that the paternal parent species of Tokyo cherry was identified using phylogenetic methods. Although previous studies failed to find differences between species closely related to C. speciosa, Kato & al. (2014) found clear differences with STRUCTURE analysis using 26 loci of simple sequence repeat (SSR) polymorphisms for these species and revealed that C. speciosa was the paternal parent.…”

“…Its sudden appearance from unknown origins has given rise to various arguments about its botanical and geographical provenance during the last hundred years (Kuitert, 1999;Iketani & al., 2006). Recent advances in molecular phylogenetics and population genetics revealed its clonal nature propagated by grafting (Innan & al., 1995;Iketani & al., 2007;Kato & al., 2012) and that it originated as an interspecific hybrid (Kato & al., 2014). Nomenclaturally, this result means that C. yedoensis is the correct name of the nothospecies resulting from crosses between C. itosakura (Siebold) Masam.…”

The flowering cherries, Cerasus (≡Prunus subg. Cerasus; Rosaceae), including C. × yedoensis 'Somei‐yoshino', are popular ornamental trees in temperate regions of the world. Recent advances in molecular and population genetics have revealed that this group originated as an interspecific hybrid. We used these findings and the verification of type specimens to examine the nomenclature of nothotaxa including C. × yedoensis. Four nothotaxa, C. × yedoensis, C. × nudiflora , C. × sacra and C. × kashioensis, were confirmed to be hybrids resulting from crosses between C. itosakura and taxa of the C. serrulata complex (C. speciosa, C. sargentii, C. jamasakura and C. leveilleana, respectively). In addition, the hybrids found on Jeju Island are C. × nudiflora, a new combination for an interspecific hybrid shown to be genetically distinct from C. × yedoensis. A new nothospecies, C. × kashioensis is proposed for a hybrid between C. itosakura and C. leveilleana.

“…However, microsatellite markers, which are informative in population genetics because of high polymorphisms have not been applied in A. melanoxylon. Simple sequence repeat (SSR) marker development, as a powerful molecular approach, is widely used in establishing genetic relationships, genetic diversity assessment, and germplasm characterization in plants (Gao et al 2012, Kato et al 2014, Selkoe and Toonen 2006. SSR could complement phenotypic data with a genotypic assessment of diversity, and SSR genetic relationship analysis could help avoid closely related parents to ensure genetic variation for continued progress (Gopal and Oyama 2005).…”

Understanding the genetic diversity of Acacia melanoxylon is very important in species selection and improvement. The present study aimed to identify microsatellite markers and determine the genetic diversity of 45 preferred clones selected from 9 Chinese districts. Seventy-six simple sequence repeat (SSR) markers developed for other Acacia species were screened. Seventeen SSR markers showed polymorphic patterns and amplified 134 alleles. Polymorphism information content (PIC) values ranged from 0.044 to 0.911. The average allele number per locus ranged between 2 and 18, averaging 8.06. Nine SSR markers were highly informative, with PIC values above 0.60. These findings demonstrated that SSR markers could be used to differentiate A. melanoxylon genotypes. Cluster analysis using UPGMA separated the 45 clones into 3 distinct groups at a similarity coefficient of 0.72. The clone groups identified in this study would be useful in developing intraspecific hybrids to exploit hybrid vigor as well as for commercial cultivation and genetic base broadening. The DNA fingerprints obtained for each clone could be used for biodiversity conservation.
