Domestication of plant and animals is presses that provide better used of them for human. Wheat is one of the oldest crops that have been domesticated 10,000 years ago. SOS and Q genes have important role in wheat domesticated. Relationship and phylogenetic of Q gene in wheat and wild relatives is very important for breeders. So, new methods such as bioinformatics can be used for this purpose. Bioinformatics analysis display that there is high conservative region among wheat and wild relatives for Q gene. Distance-matrix indicated that Triticum timopheevii and Triticum spelta have highest and lowest similarity with triticum aestivum at nucleotide level. Also phylogenetic three using UPGMA method show that Triticum timopheevii with Triticum aestivum are very closed together that it is possible that Q gene from T. timopheevii (AA genome) via introgression arrived to T. aestivum (AABBDD genome).
