| 1 | Coordinated regulation of apical hook development by gibberellins and ethylene in etiolated Arabidopsis seedlings显示文摘当在土壤发芽时,当通过土壤耸出时,黑暗成年的 Arabidopsis 幼苗开发一个顶端的钩,它保护子叶和顶端的 meristematic 纸巾。几荷尔蒙被报导清楚地调制这个过程。以前的研究证明了乙烯和赤霉素(气体) 并列地调整钩发展,尽管内在的分子的机制大部分是未知的。当 paclobutrazol 镇压了时,这里,我们显示出提高的那 GA 3 ethylene-overexpression 和 EIN3-overexpression (EIN3ox ) 导致了钩弯曲,并且 della 异种展出了夸大的钩弯曲,它要求了发信号的未经触动的乙烯小径。基因学习表明那提高 GA 的钩开发依赖于无钩 1 (HLS1 ) ,调停的一个中央管理者多重发信号小径的输入在顶端的钩开发期间。我们进一步发现那 GA 3 导致(并且 DELLA 蛋白质镇压了) 在乙烯感觉迟钝的 3/EIN3-LIKE 的 HLS1 表示 1 (EIN3/EIL1 ) 依赖举止, EIN3/EIL1 由此激活 HLS1 抄写由对它的倡导者直接有约束力。另外, DELLA 蛋白质被发现与 EIN3/EIL1 的 DNA 有约束力的领域交往并且镇压 EIN3/EIL1-regulated HLS1 表示。有 naphthylphthalamic 酸的处理,一个极的植物生长素运输禁止者,镇压 EIN3ox 线的组成地夸大的钩弯曲和 della 异种,支持那植物生长素在钩开发乙烯和 GA 小径下游地工作。一起拿,我们的结果作为联系 DELLA 的抄写因素的一个新类识别 EIN3/EIL1 并且证明 GA 由经由 EIN3/EIL1 函数的 derepression 导致 HLS1 的表达式部分与乙烯在合作支持顶端的钩形成。 | Fengying An Xing Zhang Ziqiang Zhu Yusi Ji Wenrong He Zhiqiang Jiang Mingzhe Li Hongwei Guo | 2012 | Cell Research2012,22,5: | 34 |
| 2 | The Arabidopsis PARAQUAT RESISTANT2 gene encodes an S-nitrosoglutathione reductase that is a key regulator of cell death显示文摘S-nitrosoglutathione (GSNO ) 的新陈代谢,主要生物学上活跃的氮的氧化物(没有) 种类,被进化地保存的 GSNO reductase (GSNOR ) 催化。以前的研究证明 Arabidopsis GSNOR1/HOT5 基因调整水杨酸酸由 modulating 发信号和 thermotolerance 细胞内部的 S-nitrosothiol 水平。这里,我们报导 Arabidopsis paraquat resistant2-1 (par2-1 ) 的描述显示出反房间死亡显型的异种。当由 paraquat (1,1'-dimethyl-4,4'-bipyridinium 二氯化物) 对待时,在 par2-1 的 superoxide 的生产比得上野类型的植物的,建议 PAR2 调整房间死亡的 superoxide 下游地行动。PAR2,由位置的克隆识别了,被显示与 GSNOR1/HOT5 相同。par2-1 异种在高度保存的 glycine 带一个错误感觉变化,它使变异的蛋白质变为不稳定。比作野类型, par2-1 异种有一不更高铺平,由与 4,5-diaminofluorescein diacetate 染色揭示了。与这结果一致,对待与的野类型的植物一没有施主显示抵抗到 paraquat。有趣地, GSNOR1/HOT5/PAR2 蛋白质水平除它的不变的 mRNA 水平以外,被 paraquat 导致,但是被没有施主减少。一起拿,这些结果建议 GSNOR1/HOT5/PAR2 在通过 modulating 在植物房间调整房间死亡起一个重要作用细胞内部没有水平。 | Ruiqiang Chen Shulan Sun Chun Wang Yansha Li Yan Liang Fengying An Chao Li Haili Dong Xiaohui Yang Jian Zhang Jianru Zuo | 2009 | Cell Research2009,19,12: | 14 |
| 3 | DELLA proteins interact with FLC to repress flowering transition显示文摘Flowering is a highly orchestrated and extremely ct critical process in a plant's life cycle. Previous study has ademonstrated that SUPPRESSOR OF OVEREXPRESSION OF pCONSTANS 1(SOC1) and FLOWERING LOCUS T(FT) integrate m-I the gibberellic acid(GA) signaling pathway and vernalization higpathway in regulating flowering time, but detailed molecular Hmechanisms remain largely unclear. In GA signaling pathway,DELLA proteins are a group of master transcriptional regulators, while in vernalization pathway FLOWERING LOCUS C(FLC) is a core transcriptional repressor that down-regulates the expression of SOC1 and FT. Here, we report that DELLA proteins interact with FLC in vitro and in vivo, and the LHRI domains of DELLAs and the C-terminus of MADS domain of FLC are required for these interactions.Phenotypic and gene expression analysis showed that mutation of FLC reduces while over-expression of FLC enhances the GA response in the flowering process. Further,DELLA-FLC interactions promote the repression ability of FLC on its target genes. In summary, these findings report that the interaction between MADS box transcription factor FLC and GRAS domain regulator DELLAs may integrate various signaling inputs in flowering time control, and shed new light on the regulatory mechanism both for FLC and DELLAs in regulating gene expression. | Mingzhe Li Fengying An Wenyang Li Mengdi Ma Ying Feng Xing Zhang Hongwei Guo | 2016 | Journal of Integrative Plant Biology2016,58,7: | 7 |
| 4 | Adenine Phosphoribosyl Transferase 1 is a Key Enzyme Catalyzing Cytokinin Conversion from Nucleobases to Nucleotides in Arabidopsis显示文摘在植物,细胞激动素包括细胞激动素生合成,互变现象, inactivation,和降级,新陈代谢的进程在细胞激动素动态平衡和植物开发的规定起关键作用。嘌呤新陈代谢的酶被暗示了在以前的工作催化细胞激动素互变现象。在这研究,我们报导腺嘌 Phosphoribosyl Transferase 1 (APT1 ) 是高剂量的细胞激动素抵抗的异种的原因的基因。APT1 从免费的底催化细胞激动素变换到核苷酸,并且在 Arabidopsis 腺嘌 Phosphoribosyl Transferase 家庭的五个成员之中是机能上地占优势的。在工厂的 APT1 活动的损失导致细胞激动素底的过量累积,因此唤起无数调整细胞激动素的回答例如推迟的叶老朽, anthocyanin 累积,和下游的基因表示。因此,我们的学习把 APT1 定义为由 phosphoribosylation 参予细胞激动素 inactivation 的关键新陈代谢的酶。 | Xinyan Zhang Yutao Chen Xin Lin Xinyu Hong Ying Zhu Wenyang Li Wenrong He Fengying An Hongwei Guo | 2013 | Molecular Plant2013,6,5: | 2 |
