  flower meristem identity genes
Further studies demonstrated that the early flowering phenotype in transgenic plants could be correlated with the upregulation of some flowering time genes and flower meristem identity genes.
      
FLORICAULA/LEAFY-like genes were initially characterized as flower meristem identity genes.
      
In angiosperms, the formation of the flower meristem is controlled by partially redundant flower meristem identity genes of which FLORICAULA (FLO)/LEAFY (LFY?) plays a central role.

A pair of degenerate oligonucleotides to highly conserved regions at the 3’terminus of LEAFY(LFY) gene and its homologues,the flower meristem identity genes,is used to amplify a fragment of 883bp by PCR from the citrus genomic DNA.Sequencing indicated that there is an intron of 473bp in the fragment.The splice donor site and the splice acceptor site are in identical position to the LFY gene and its homologues.The amino acid sequence deduced from the exons is 77%-97% homologous to that of the corresponding regions of LFY and its orthologues.The expression patterns of the citrus LFY homolog( csLFY )were analyzed by RT PCR.The result indicates that csLFY expression was detected in vegetative and flower buds from the adult tree as well as vegetative buds from the several month old seedlings.However,the level of the csLFY transcripts in the juvenile buds is lower than in the flower buds.

根据不同植物LEAFY (LFY)同源基因 3’端序列高度保守性 ,设计合成简并引物 ,采用PCR技术首次从柑桔基因组DNA中分离出一条长 883bp的柑桔LFY同源基因(csLFY)片段。序列分析表明 ,所扩增的 883bpDNA片段中包含一个长 4 76bp的内含子 ,拼接位点与其他植物的LFY同源基因一致。由外显子推导的氨基酸序列与其它植物LFY同源基因的相应区域氨基酸序列同源性为 77%~ 97% ,其中与烟草NFL和矮牵牛ALF的同源性最高 ,达到 97%。RT—PCR研究表明 ,csLFY在柑桔成年结果枝上的花芽和营养芽以及童期幼苗的营养芽中均有表达 ,但童期营养芽中的表达强度明显低于花芽。

Flower_meristem_identity gene AP1 was isolated from Arabidopsis thaliana (L.) Heynh. by RT_PCR. The result of the sequencing showed that only a single nucleotide change was found in this AP1 gene compared with the published sequence, but this changed nucleotide did not effect the primary structure of the protein. Driven by the CaMV 35S promoter, AP1 was stably integrated into the genome of Petunia hybrida Vilm. by Agrobacterium tumefaciens (Smith et Townsend) Conn Ti plasmid_mediated...

Flower_meristem_identity gene AP1 was isolated from Arabidopsis thaliana (L.) Heynh. by RT_PCR. The result of the sequencing showed that only a single nucleotide change was found in this AP1 gene compared with the published sequence, but this changed nucleotide did not effect the primary structure of the protein. Driven by the CaMV 35S promoter, AP1 was stably integrated into the genome of Petunia hybrida Vilm. by Agrobacterium tumefaciens (Smith et Townsend) Conn Ti plasmid_mediated transformation. The intergration of the transgene was identified by PCR and Southern blot analysis. The R 0 generation of two transgenic lines could flower earlier and constantly even in the tissue culture flask, differing from the non_transformed Petunia hybrida .

利用RT_PCR方法从拟南芥 (Arabidopsisthaliana (L .)Heynh .)中克隆了花分生组织决定基因 (flower_meristem_identitygene)AP1,进行了全序列测定。测序结果显示 ,所得到的基因与发表的序列仅有一个碱基的差异 ,但并不影响蛋白质的一级结构。将AP1基因克隆入植物中间载体p2 0 8,通过根癌土壤杆菌 (Agrobacteriumtumefaciens (SmithetTownsend)Conn)介导的方法转化矮牵牛 (PetuniahybridaVilm .)。对转基因植株进行了PCR和Southern检测 ,所得到的两个株系的转基因矮牵牛在R0 代即表现出提前且持续不断地开花的特性 ,与对照差异显著
