RESUMO

Prunus clarofolia (Schneid.) Yu et Li is a very attractive wild flowering cherry endemic to China. In this study, the complete chloroplast genome of P. clarofolia was assembled. The total length of the chloroplast genome was 157,899 bp, containing a pair of inverted repeat regions of 26,393 bp each, separated by a small single-copy region of 19,142 bp, and a large single-copy region of 85,971 bp. The overall GC content of the chloroplast genome was 36.71%. The genome contained 131 genes, including 85 protein-coding genes, 37 tRNA genes, eight rRNA genes, and one pseudogene. Phylogenetic analysis revealed that P. clarofolia and P. pseudocerasus showed the closest relationship.

RESUMO

To provide a scientific basis for the conservation and exploitation of wild Cerasus species in Dawei Mountain, we investigated the community characteristics and species diversity of Cerasus species. The results showed that there were four Cerasus communities, C. campanulata, C. diel-siana, C. conradinae and C. xueluoensis, in Dawei Mountain. Phaenerophyte in the life form and pantropical elements in the local flora were both dominant. The shrub layer had higher species diversity than that of the arbor layer. Species diversity of those four communities was following the order of C. dielsiana, C. conradinae, C. campanulata and C. xueluoensis. The community structure was relatively stable when young and mature individuals of Cerasus predominated. The ground dia-meter class structure indicated that the C. xueluoensis population was a growing population with a typical pyramid structure. The C. conradinae community was mono-dominated by C. conradinae, with C. dielsiana and C. campanulata as the important companion species. Those three Cerasus species would be replaced by other coniferous and broadleaved species due to the shortage of natural regeneration.

RESUMO

Prunus conradinae is a flowering cherry species with high ornamental value. In this study, the complete chloroplast (cp) genome of P. conradinae was obtained using a genome skimming approach. The cp genome was 158,019 bp long, with a large single-copy region of 85,910 bp and a small single-copy region of 19,247 bp separated by two inverted repeats of 26,431 bp. It encodes 130 genes, including 85 protein-coding genes, 37 tRNA genes, and eight ribosomal RNA genes. The phylogenetic analysis indicated that P. conradinae is closely related to the congeners P. maximowiczii, P. takesimensis, P. speciosa, P. serrulata var. spontanea, P. discoidea, and P. matuurai.
