The conserved regions of rRNA and tRNA genes exhibited higher sequence similarity among plant species. Five primer pairs were designed from the conserved regions distributing in psbA~trnK, psbB~psbH, rpl23~trnI, trnR-ACG~trnN-GUU and trnY-GUA~trnD-GUC, respectively to amplify sequences about 500~600 bp, 800~900 bp, 650~700 bp (350 bp, not legume species), 700~800 bp (400 bp in dicotyledon), and 500~600 bp.

经由上述比对分析后设计出5引子对，位於叶绿体基因体的位置分别为psbA~trnK、psbB~psbH、rpl23~trnI、trnR-ACG~trnN-GUU及trnY-GUA~ trnD-GUC，预期实际应用在其他物种上所能增幅之变异序列长度分别约为500~600 bp、800~900 bp、650~700 bp (豆科以外物种为350 bp)、700~800 bp (双子叶植物为400 bp)及500~600 bp。
