拟南芥TIR3(transport inhibitor response3)基因通过调控生长素的极性运输广泛参与器官的形态建成。TIR3基因的缺失会导致生长素极性运输和浓度分布发生改变,致使植物花、叶、根等器官出现明显的发育缺陷。此外,TIR3可作为一种新的调节因子参与植物免疫防御机制和生理节律的调控。本文综述了TIR3通过调控NBP(NPA binding protein)及PIN1(PIN-FORmED1)蛋白进而影响植物对生长素响应的机制,及其参与植物花、叶、根等器官形态建成的分子机制。简述了TIR3通过调控生长素的运输进而引起茉莉酸(JA)响应变化、JA和乙烯(ET)的协同作用以及其他激素的相互作用,从而参与植物免疫应答过程。简述了TIR3等位基因可能参与调控植物生理节律的相关研究。展望了TIR3未来的研究方向、发展趋势及对农业生产的借鉴意义。

在许多生物体中,Polycomb group(PcG)蛋白在调节基因表达和维持发育状态方面起着重要作用。PcG蛋白以多种形式存在,主要形式为Polycomb repressive complex 1(PRC1)和Polycomb repressive complex2(PRC2)。其中PRC2是一种四亚基组蛋白甲基转移酶复合物,其作用是抑制基因表达。在许多物种的发育过程中,PRC2会通过形成不同的复合体发挥表观遗传调控作用,甚至在辅助组分的帮助下能够改变复合体活性或提供额外功能。本研究就PRC2在不同物种中的组成及功能研究进行综述,并对PRC2未来研究方向进行展望。

多梳蛋白家族Polycomb(Pc-G)在表观遗传调控中起重要作用,从生化和功能上可将Pc-G分成两个主要的核心蛋白复合体PRC1(Polycomb repressive complexes 1)和PRC2(Polycomb repressive complexes 2)。CLF(CURLY LEAF)作为PRC2蛋白复合体的重要组分之一,参与调控植物不同阶段的生长发育。有研究表明CLF能够通过调节下游基因的表达影响叶片发育及花发育,控制植物根和侧枝的伸长与生长,同时在种子的生长发育中也起着重要作用。本文主要介绍CLF在植物器官形态建成中的功能,为进一步研究CLF在植物发育中的作用提供参考。

目的:探讨转化生长因子-β1(TGF-β1)分子表达水平及其编码区基因多态性与多发性骨髓瘤(mu ltip le myelo-m a,mm)的关系。方法:应用ELISA方法检测标本血浆TGF-β1的浓度,应用L ightCyc ler实时荧光PCR结合熔点曲线分析的方法检测转化生长因子-β1编码区3个基因多态性:codon10 T>C(Leu10Pro)、codon25 G>C(Arg25Pro)和codon263 C>T(Thr263 Ile)。结果:患者血浆TGF-β1浓度明显高于对照组,但TGF-β1基因codon10位点各种基因型和等位基因在对照组和mm患者组以及mm患者各型之间的分布频率并没有显著差异,而且mm患者各种基因型血浆TGF-β1的浓度也没有显著差异,TGF-β1基因codon25和codon263位点均不存在预想中的基因多态性。结论:转化生长因子-β1可能在多发性骨髓瘤的发生中起到一定的作用,但该因子基因编码区多态性并不会影响血浆TGF-β1的浓度,也与mm的发生以及亚型没有明确的相关性。
