Many studies show that leafy is high homolog even among distantly related plant species . exception of these , little studies on tissue culture and transformation of ginkgo have been done . this paper emphasizes on the isolation , cloning and analysing two ginkgo orthologs of leafy from the male tree 為此，本實驗從銀杏leafy同源基因的克隆入手，分析其雌雄株lfy基因結構差異，構建lfy基因的植物正義反義表達載體，建立矮牽牛遺傳轉化體系，以研究銀杏lfy同源基因的功能，同時建立了銀杏組織培養體系，為銀杏的遺傳轉化和提早開花結果奠定基礎。
The tumor cells transfected with restin are arrested in gl phase and the cell proliferation is inhibited . it implies that restin may be correlated to cell cycle regulation . other data showed that the necdin , a homolog of restin , could suppress cell growth by interacting with transcription factor e2f1 and p53 而與restin的同源蛋白的necdin ，可以與細胞周期促進蛋白sv40大t抗原、腺病毒eia 、轉錄因子ezfi等相互作用，抑制細胞生長;也可以和轉錄因子p53作用參與生長抑制和抑制p53誘導的細胞凋亡。
The two single - pass transmembrane proteins , delta and serrate , have been identified as notch ligands . the transcription factor suppressor of hairless [ su ( h ) ] is the major downstream effector of notch signaling pathway . rbp - j , the mammalian homolog of su ( h ) , recognizes the core sequence ( c / tgtgggaa ) of dna Rbp - j是果蠅促神經發生基因su ( h ) ( suppressorofhairless )在哺乳動物的同源物，它通過其識別序列( c tgtgggaa )結合于受調控基因的啟動子區，在轉錄激活因子的驅動下調節細胞分化和個體發育相關基因的表達。
Notch interaction with its ligands induces the cleavage of its intracellular domain ( ic ) , and the notch ic translocates to the nucleus and binds to rbp - j , the mammalian homolog of su ( h ) , to transactivate transcription of target genes such as e ( spl ) ( enhancer of split ) , hesl ( hairy and enhancer of split ) and hes5 four notch receptors and their ligands are differentially and redundantly expressed in a variety of vertebrate tissues 它通過其識別序列（ cogtgggaa ）結合于受調控基因的啟動子區，在轉錄激活因子的驅動下調節細胞分化和個體發育相關基因的表達。在沒有n 。 tch胞內段的情況下， rbpj可與包含sm盯（ silencingmediatorforretlnoldandthyroidhormonereceptor ）和組蛋白去乙酞化酶的轉錄輔助抑制復合物結合，當notch信號被激活時； rbpj可與n 。
A homolog of ga sbeta - hydroxylase gene expression pattern was examined . hybridization signals of this gene could be detected at day 5 and however , they appear again after day 10 when explants cultured with hormones . it has the similar pattern when the explants cultured without hormones or uncultured 風信子ga羥基化酶類似基回在外植體表達，在含有外源撒素條件下培養的前5天受到激素的抑制而幾乎不表達，第10天開始在花分生組織中表達。
Dreb - type transcription factors can accept stress signals from environment and promote the expression of stress - tolerant genes . four dreb homolog genes , gmdreba , gmdrebb , gmdrebc and osdreb4 - 2 were isolated from soybean [ glycine max ( l . ) merr . ] Dreb類轉錄因子能接受逆境信號并啟動逆境應答基因的表達。在本研究中，以大豆和水稻為材料，共克隆了4個dreb的同源基因，分別命名為gmdreba ， gmdrebb ， gmdrebc和osdreb4 - 2 。
Moreover the pf40 gene was ubiquity distributed in cereal crop genome . dicots such as tobacco and tomato do not have the pf40 homolog gene , but we found its homolog gene maybe present in arabidopsis genome 用該基因與玉米、小麥、水稻主要禾本科作物的基因組dna雜交，結果表明pf40基因及其同源基因普遍存在于禾谷類植物中，同時在擬南芥基因組中也有pf40基因的同源序列。
We report here the cloning of a homolog of this gene from dunaliella salina . this cloned gene produces as protein with photolyase activity when expressd in escherichia coli 運用blast方法對est序列進行分析，初步預測該est序列為光裂合酶藍光受體蛋白質家族中一個成員的部分cdna 。
Functional genomics uses as its starting point the isolated gene whose function is to be determined ， and then selects a model organism in which a homolog of that gene exists 功能基因組用功能不明的分離基因作為起始點，然后選擇具有該同源基因的生物模型。
