Abstract: In order to obtain the important expression information of LLGLO1 gene during the process of flower development,the temporal and spatial changes of LLGLO1 gene at different development stages of floral buds by in situ hybridization,using the floral buds of Lilium longiflorum as materials and the special sequence of LLGLO1 gene as the probe. Result indicated that LLGLO1 gene was expressed in the four whorls of floral-organ,including outer tepal,inner tepal,stamen,and carpel. It also indicated that the expression level of LLGLO1 gene varies with different development stages of floral buds. The expression level was higher in the 2.0 cm and 3.0 cm floral buds than that in the 0.5 cm and 1.0 cm ones,showing that the expression level of LLGLO1 gene increases with the development of floral-organ.

Key words: Lilium, Lilium longiflorum, floral bud, flower development, in situ hybridization, LLGLO1 gene
