摘要
A cDNA clone related to the vernalization in winter wheat(verc203)was harvested from the en-riched cold-induced cDNA library of 10~4 pfu with differential screening.The insert of verc203 in λ gt10 vector wassubcloned into the sites between BamH Ⅰ and Hind Ⅲ in pUC19 plasmid after being amplified with PCR.the analysis of the Northern blotting with a probe of verc203 indicated that the verc203 has a negative signalfor the control and the devernalized mRNA and a positive signal for the vernalized winter wheat and non-vernalized spring wheat at about 2.6 kb.
