homology class
1.It contains 43 restriction sites for Aat I,Aat II,Bgl I,Dpn I,Dpn II,EcoR II,Hae I,Hae II,Hae III,Hinf I,Hpa II,Mae II,Mae III,Nba I,Oxa I and Sst IV. The sequence homology for the chitinase(Class I)mature protein genes between V. sesquipedalis and V. unguiculata,Phaseolus vulgaris,Pisum sativum,Nicotiana tabacum,Triticum aestivum and Oryza sativa is decreased respectively.
