ABSTRACT
Objective:
To analyze the ribosomal DNA internal transcribed spacer (rDNA-ITS) sequence of Cichorium intybus and C. glandulosum from different habitats, and to provide DNA molecular marker for the identification of chicory.Methods:
The total DNA was extracted from the samples of C. intybus and C. glandulosum from 14 habitats by rapid broad spectrum of plant genomic DNA extraction kit. The ITS sequence was amplified by PCR with universal primer of ITS and then sequenced. The two kinds of ITS sequences were compared by DNAMAN V6 software. The cluster analysis was adopted by SPSS 17.0 after the different ITS bases from all the samples were mathematically treated.Results:
The intraspecies identity of ITS sequence was above 99.2% in C. intybus, and that in C. glandulosum was above 99.8%, while the interspecies identity of ITS sequence was below 99.2%. There were various specific information sites in the ITS sequences of the two kinds of chicory.Conclusion:
The ITS sequence is an available molecular marker for the identification of C. glandulosum and C. intybus.
