The tribe Triticeae provides a vast gene pool for improving the genetic variation of common wheat (Triticum aestivum L.).However,the inter-specific hybridization commonly occurred under natural and artificial conditions increase the difficulty to the molecular polygenetic analysis of Triticeae based on data from nuclear genes.The extra-chromosomal genome from both chloroplast and mitochondrial provide a conserved system to study the genomic inheritance and evolution.
