Objective: To understand the molecular mechanism in genetic variation within species

and identify the differentially expressed genes among 3 anomalies of rhubarb under the same genetic background and cultivated environment. Method: The differentially expressed genes of different anomalies of rhubarb in vigorous growing stage were identified by cDNA-SRAP.Their functions were inferred through bioinformatics method. Result: Five different gene fragments and 4 common gene fragments but differentially expressed were identified

among which

the function of 5 were unknown

and the rest were involved in plant growth

light signal transmitting

disease-resistance

and water transporting. Conclusion: For the first time

the differentially expressed genes were cloned from the different anomalies of rhubarb. This provided the basis of the screening of fine anomalies and varieties

and the research of functional genomics.
