The homologous cDNA of LFY, CFL, were cloned from cucumber ( Cucumis sativus L.). Southern blot analysis showed it was a single copy gene in the cucumber genome. Northern blot analysis showed that it expressed in the floral buds and young leaves. The possible role of CFL in the floral and vegetative development of cucumber plant was discussed.展开更多
The promoter region of NFL1 gene in tobacco was cloned by a novel PCR method,fused with the report gene GUS and transformed tobacco plants.The expression of GUS in the shoot apex of transgenic seedlings was detected.
