“…Lindl (loquat), which belongs to Rosaceae, is widely distributed in temperate and subtropical zones of Asian, European and American countries (Gisbert et al 2009). Eriobotrya japonica originated in China and later was introduced to Mediterranean basin, Japan and Florida (Blasco et al 2014). Eriobotrya japonica is an important economic fruit crop with high edible, medical as well as ornamental values.…”

“…Soriano et al (2005) first demonstrated the usefulness of SSRs markers in genetic analysis and identification in E. japonica . Many researches utilized AFLP and SSRs markers to investigate genetic variation, diversity and identification among loquat accessions (He et al 2011; Fukuda et al 2013; Blasco et al 2014), which provided information for diversity analysis and plant breeding program. However, few molecular markers based on plastomes have been developed since completed plastid genome of E. japonica is not available, lagging behind other species of Rosaceae.…”

Eriobotrya japonica (Thunb.) Lindl (loquat) is an evergreen Rosaceae fruit tree widely distributed in subtropical regions. Its leaves are considered as traditional Chinese medicine and are of high medical value especially for cough and emesis. Thus, we sequenced the complete plastid genome of E. japonica to better utilize this important species. The complete plastid genome of E. japonica is 159,137 bp in length, which contains a typical quadripartite structure with a pair of inverted repeats (IR, 26,326 bp) separated by large (LSC, 89,202 bp) and small (SSC, 19,283 bp) single-copy regions. The E. japonica plastid genome encodes 112 unique genes which consist of 78 protein-coding genes, 30 tRNA genes and 4 rRNA genes. Gene structure and content of E. japonica plastid genome are quite conserved and show similarity among Rosaceous species. Five large indels are unique to E. japonica in comparison with Pyrus pyrifolia and Prunus persica, which could be utilized as molecular markers. A total of 72 simple sequence repeats (SSRs) were detected and most of them are mononucleotide repeats composed of A or T, indicating a strong A or T bias for base composition. The Ka and Ks ratios of most genes are lower than 1, which suggests that most genes are under purifying selection. The phylogenetic analysis described the evolutionary relationship within Rosaceae and fully supported a close relationship between E. japonica and P. pyrifolia.

“…Eriobotrya japonica is one of the most important subtropical characteristic fruits in China, which belongs to the Rosaceae family and origins in China and later was introduced to Mediterranean basin, Japan, Vietnam, and America (Blasco et al 2014). It is also an important economic fruit crop in summer and has the high edible, medical as well as ornamental values.…”

Eriobotrya japonica is the most important economic fruit crop with high edible, medical as well as ornamental values in China. In this study, we presented the complete chloroplast genome of E. japonica. The chloroplast genome size is 159,107 bp, containing a large single-copy region (87,213 bp), a small single-copy region (19,268 bp), and a pair of IR regions (26,313 bp). The overall GC contents of the chloroplast genome are 36.7%. Eriobotrya japonica whole chloroplast genome contains 129 genes, including 84 protein-coding genes, 37 tRNAs, and 8 rRNAs. Phylogenetic maximum likelihood (ML) analysis based on 15 plant species chloroplast genomes indicates that E. japonica is closely related to Eriobotrya bengalensis. These complete chloroplast genomes can be subsequently used for valuable species research of Eriobotrya. ARTICLE HISTORY

“…Regarding loquat, there have been reports on the establishment of plant regeneration system and haploid induction through anthers (Li et al 2008;Blasco et al 2015b) or isolated microspore culture (Padoan et al 2010;Blasco et al 2014). Haploids are of great interest, since they can allow the fixation of interesting traits in a homozygous state (Germanà 2011b).…”

“…One important tool for breeding are the genetic resources kept at the germplasm collections. The most important European collection is held at the IVIA, that includes more than 120 cultivars (Soriano et al 2005;Gisbert et al 2009;Blasco et al 2014). In terms of increasing the diversity of fruit types, polyploidy has an important role in genetic and phenotype diversity and breeding (Dhooghe et al 2011;Xing et al 2011).…”
