利用生物信息学方法对荞麦属叶绿体进行比较基因组学研究.结果表明,荞麦属已测的5种植物叶绿体基因组大小在159 265～159 599 bp之间;GC含量介于37.81％～37.98％之间,基因的数目、类型与拷贝数差异小;区域边界基本一致;SSR类型的种类与数目相似;该属的LSC区域和SSC区域比IR区域多态性位点变异高,其中非编码区trnS_trnG、rps4_trnT和rpl32_trnL是变异最高的热点区域;系统分析表明,野生金荞麦与苦荞的亲缘关系最近.
Structural Variation and Molecular Evolution of Chloroplast Genomes in Five Species of Fagopyrum
In this study,comparative genomics of Fagopyrum chloroplasts was studied using bioinfor-matics methods.The results showed that the chloroplast genome sizes of the five species of Fagopy-rum ranged from 159 265 to 159 599 bp;the GC content ranged from 37.81％to 37.98％,and there was a small difference in the number,type,and copy number of genes;The regional boundaries were basically consistent;The type and number of SSR types were similar;The polymorphism of LSC and SSC in this genus was higher than that in IR region,and the non-coding regions trnS-trnG,rps4-TrnT and rpl32-TrnL were the hot-spot region with the highest variation;Systematic analysis showed that F.leptopodum had the closest genetic relationship with F.tataricum.
