与其他夹竹桃科的cp基因组相似。其LSC、SSC、IR和全基因组的DN

Similar to the cp genome of other Apocynaceae. The DNA G+C content of its LSC, SSC, IR and whole genome are 36.49, 32.41, 43.3 and 38.36 mol %, respectively, which is similar to the chloroplast genomes of other species of Apocynaceae. DNA G+C content is an important indicator for judging the genetic relationship of oleander, and the cpDNA G+C content of oleander is similar to other species in the Apocynaceae[48-53]. The DNA G+C content in IR region is higher than other regions (LSC, SSC); this phenomenon is also common in other plants [54-56]. The relatively high DNA G+C content in IR region is mainly attributed to rRNA genes and tRNA genes [57,58].

Similar to the cp genome of other bamboo peaches. Its LSC, SSC, IR, and genome-wide DNA G-C content was 36.49, 32.41, 43.3 and 38.36 mol, respectively, similar to the stegreen genomes of other species in the bamboo peach species. The content of DNA G-C is an important index to judge the kinship relationship of bamboo peaches, and the cpDNA G-C content of bamboo peaches is similar to that of other species of bamboo peaches. The DNA G-C content in the IR region is higher than in other regions (LSC, SSC); The relatively high levels of DNA G-C in the IR region are mainly attributable to the rRNA gene and the tRNA gene.

It is similar to the CP genome of other oleraceae. The DNA G + C contents of LSC, SSC, IR and whole genome were 36.49, 32.41, 43.3 and 38.36 mol%, respectively, which were similar to those of other species in Nerium family. DNA G + C content is an important index to judge the genetic relationship of Nerium oleracea, and the cpDNA G + C content of Nerium indicum is similar to other species of Apocynaceae [48-53]. The content of DNA G + C in IR region is higher than that in other regions (LSC, SSC); this phenomenon is also common in other plants [54-56]. The relatively high DNA G + C content in IR region was mainly attributed to rRNA gene and tRNA gene [57,58].<br>
