    Description: Touch sensation is essential for behaviours ranging from environmental exploration to social interaction; however, the underlying mechanisms are largely unknown. In Drosophila larvae, two types of sensory neurons, class III and class IV dendritic arborization neurons, tile the body wall. The mechanotransduction channel PIEZO in class IV neurons is essential for sensing noxious mechanical stimuli but is not involved in gentle touch. On the basis of electrophysiological-recording, calcium-imaging and behavioural studies, here we report that class III dendritic arborization neurons are touch sensitive and contribute to gentle-touch sensation. We further identify NOMPC (No mechanoreceptor potential C), a member of the transient receptor potential (TRP) family of ion channels, as a mechanotransduction channel for gentle touch. NOMPC is highly expressed in class III neurons and is required for their mechanotransduction. Moreover, ectopic NOMPC expression confers touch sensitivity to the normally touch-insensitive class IV neurons. In addition to the critical role of NOMPC in eliciting gentle-touch-mediated behavioural responses, expression of this protein in the Drosophila S2 cell line also gives rise to mechanosensitive channels in which ion selectivity can be altered by NOMPC mutation, indicating that NOMPC is a pore-forming subunit of a mechanotransduction channel. Our study establishes NOMPC as a bona fide mechanotransduction channel that satisfies all four criteria proposed for a channel to qualify as a transducer of mechanical stimuli and mediates gentle-touch sensation. Our study also suggests that different mechanosensitive channels may be used to sense gentle touch versus noxious mechanical stimuli.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3917554/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3917554/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yan, Zhiqiang -- Zhang, Wei -- He, Ye -- Gorczyca, David -- Xiang, Yang -- Cheng, Li E -- Meltzer, Shan -- Jan, Lily Yeh -- Jan, Yuh Nung -- 5R01MH084234/MH/NIMH NIH HHS/ -- P30 DK063720/DK/NIDDK NIH HHS/ -- R01 MH084234/MH/NIMH NIH HHS/ -- R37 NS040929/NS/NINDS NIH HHS/ -- R37NS040929/NS/NINDS NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2013 Jan 10;493(7431):221-5. doi: 10.1038/nature11685.

    Description: Understanding the diversity of human tissues is fundamental to disease and requires linking genetic information, which is identical in most of an individual's cells, with epigenetic mechanisms that could have tissue-specific roles. Surveys of DNA methylation in human tissues have established a complex landscape including both tissue-specific and invariant methylation patterns. Here we report high coverage methylomes that catalogue cytosine methylation in all contexts for the major human organ systems, integrated with matched transcriptomes and genomic sequence. By combining these diverse data types with each individuals' phased genome, we identified widespread tissue-specific differential CG methylation (mCG), partially methylated domains, allele-specific methylation and transcription, and the unexpected presence of non-CG methylation (mCH) in almost all human tissues. mCH correlated with tissue-specific functions, and using this mark, we made novel predictions of genes that escape X-chromosome inactivation in specific tissues. Overall, DNA methylation in several genomic contexts varies substantially among human tissues.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4499021/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4499021/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schultz, Matthew D -- He, Yupeng -- Whitaker, John W -- Hariharan, Manoj -- Mukamel, Eran A -- Leung, Danny -- Rajagopal, Nisha -- Nery, Joseph R -- Urich, Mark A -- Chen, Huaming -- Lin, Shin -- Lin, Yiing -- Jung, Inkyung -- Schmitt, Anthony D -- Selvaraj, Siddarth -- Ren, Bing -- Sejnowski, Terrence J -- Wang, Wei -- Ecker, Joseph R -- F32 HL110473/HL/NHLBI NIH HHS/ -- F32HL110473/HL/NHLBI NIH HHS/ -- K99 HL119617/HL/NHLBI NIH HHS/ -- K99 NS080911/NS/NINDS NIH HHS/ -- K99HL119617/HL/NHLBI NIH HHS/ -- R00 NS080911/NS/NINDS NIH HHS/ -- R00NS080911/NS/NINDS NIH HHS/ -- R01 ES024984/ES/NIEHS NIH HHS/ -- T32 GM008666/GM/NIGMS NIH HHS/ -- U01 ES017166/ES/NIEHS NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2015 Jul 9;523(7559):212-6. doi: 10.1038/nature14465.

    Description: Potato (Solanum tuberosum L.) is the world's most important non-grain food crop and is central to global food security. It is clonally propagated, highly heterozygous, autotetraploid, and suffers acute inbreeding depression. Here we use a homozygous doubled-monoploid potato clone to sequence and assemble 86% of the 844-megabase genome. We predict 39,031 protein-coding genes and present evidence for at least two genome duplication events indicative of a palaeopolyploid origin. As the first genome sequence of an asterid, the potato genome reveals 2,642 genes specific to this large angiosperm clade. We also sequenced a heterozygous diploid clone and show that gene presence/absence variants and other potentially deleterious mutations occur frequently and are a likely cause of inbreeding depression. Gene family expansion, tissue-specific expression and recruitment of genes to new pathways contributed to the evolution of tuber development. The potato genome sequence provides a platform for genetic improvement of this vital crop.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Potato Genome Sequencing Consortium -- Xu, Xun -- Pan, Shengkai -- Cheng, Shifeng -- Zhang, Bo -- Mu, Desheng -- Ni, Peixiang -- Zhang, Gengyun -- Yang, Shuang -- Li, Ruiqiang -- Wang, Jun -- Orjeda, Gisella -- Guzman, Frank -- Torres, Michael -- Lozano, Roberto -- Ponce, Olga -- Martinez, Diana -- De la Cruz, German -- Chakrabarti, S K -- Patil, Virupaksh U -- Skryabin, Konstantin G -- Kuznetsov, Boris B -- Ravin, Nikolai V -- Kolganova, Tatjana V -- Beletsky, Alexey V -- Mardanov, Andrei V -- Di Genova, Alex -- Bolser, Daniel M -- Martin, David M A -- Li, Guangcun -- Yang, Yu -- Kuang, Hanhui -- Hu, Qun -- Xiong, Xingyao -- Bishop, Gerard J -- Sagredo, Boris -- Mejia, Nilo -- Zagorski, Wlodzimierz -- Gromadka, Robert -- Gawor, Jan -- Szczesny, Pawel -- Huang, Sanwen -- Zhang, Zhonghua -- Liang, Chunbo -- He, Jun -- Li, Ying -- He, Ying -- Xu, Jianfei -- Zhang, Youjun -- Xie, Binyan -- Du, Yongchen -- Qu, Dongyu -- Bonierbale, Merideth -- Ghislain, Marc -- Herrera, Maria del Rosario -- Giuliano, Giovanni -- Pietrella, Marco -- Perrotta, Gaetano -- Facella, Paolo -- O'Brien, Kimberly -- Feingold, Sergio E -- Barreiro, Leandro E -- Massa, Gabriela A -- Diambra, Luis -- Whitty, Brett R -- Vaillancourt, Brieanne -- Lin, Haining -- Massa, Alicia N -- Geoffroy, Michael -- Lundback, Steven -- DellaPenna, Dean -- Buell, C Robin -- Sharma, Sanjeev Kumar -- Marshall, David F -- Waugh, Robbie -- Bryan, Glenn J -- Destefanis, Marialaura -- Nagy, Istvan -- Milbourne, Dan -- Thomson, Susan J -- Fiers, Mark -- Jacobs, Jeanne M E -- Nielsen, Kare L -- Sonderkaer, Mads -- Iovene, Marina -- Torres, Giovana A -- Jiang, Jiming -- Veilleux, Richard E -- Bachem, Christian W B -- de Boer, Jan -- Borm, Theo -- Kloosterman, Bjorn -- van Eck, Herman -- Datema, Erwin -- Hekkert, Bas te Lintel -- Goverse, Aska -- van Ham, Roeland C H J -- Visser, Richard G F -- BB/F012640/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/F012640/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- WT 083481/Wellcome Trust/United Kingdom -- England -- Nature. 2011 Jul 10;475(7355):189-95. doi: 10.1038/nature10158.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉BGI-Shenzhen, Chinese Ministry of Agricultural, Key Lab of Genomics, Beishan Industrial Zone, Yantian District, Shenzhen 518083, China.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21743474" target="_blank"〉PubMed〈/a〉

    Description: Eukaryotic transcription initiation requires the assembly of general transcription factors into a pre-initiation complex that ensures the accurate loading of RNA polymerase II (Pol II) at the transcription start site. The molecular mechanism and function of this assembly have remained elusive due to lack of structural information. Here we have used an in vitro reconstituted system to study the stepwise assembly of human TBP, TFIIA, TFIIB, Pol II, TFIIF, TFIIE and TFIIH onto promoter DNA using cryo-electron microscopy. Our structural analyses provide pseudo-atomic models at various stages of transcription initiation that illuminate critical molecular interactions, including how TFIIF engages Pol II and promoter DNA to stabilize both the closed pre-initiation complex and the open-promoter complex, and to regulate start--initiation complexes, combined with the localization of the TFIIH helicases XPD and XPB, support a DNA translocation model of XPB and explain its essential role in promoter opening.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3612373/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3612373/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉He, Yuan -- Fang, Jie -- Taatjes, Dylan J -- Nogales, Eva -- CA127364/CA/NCI NIH HHS/ -- GM63072/GM/NIGMS NIH HHS/ -- R01 CA127364/CA/NCI NIH HHS/ -- R01 GM063072/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2013 Mar 28;495(7442):481-6. doi: 10.1038/nature11991.

    Description: The Pacific oyster Crassostrea gigas belongs to one of the most species-rich but genomically poorly explored phyla, the Mollusca. Here we report the sequencing and assembly of the oyster genome using short reads and a fosmid-pooling strategy, along with transcriptomes of development and stress response and the proteome of the shell. The oyster genome is highly polymorphic and rich in repetitive sequences, with some transposable elements still actively shaping variation. Transcriptome studies reveal an extensive set of genes responding to environmental stress. The expansion of genes coding for heat shock protein 70 and inhibitors of apoptosis is probably central to the oyster's adaptation to sessile life in the highly stressful intertidal zone. Our analyses also show that shell formation in molluscs is more complex than currently understood and involves extensive participation of cells and their exosomes. The oyster genome sequence fills a void in our understanding of the Lophotrochozoa.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhang, Guofan -- Fang, Xiaodong -- Guo, Ximing -- Li, Li -- Luo, Ruibang -- Xu, Fei -- Yang, Pengcheng -- Zhang, Linlin -- Wang, Xiaotong -- Qi, Haigang -- Xiong, Zhiqiang -- Que, Huayong -- Xie, Yinlong -- Holland, Peter W H -- Paps, Jordi -- Zhu, Yabing -- Wu, Fucun -- Chen, Yuanxin -- Wang, Jiafeng -- Peng, Chunfang -- Meng, Jie -- Yang, Lan -- Liu, Jun -- Wen, Bo -- Zhang, Na -- Huang, Zhiyong -- Zhu, Qihui -- Feng, Yue -- Mount, Andrew -- Hedgecock, Dennis -- Xu, Zhe -- Liu, Yunjie -- Domazet-Loso, Tomislav -- Du, Yishuai -- Sun, Xiaoqing -- Zhang, Shoudu -- Liu, Binghang -- Cheng, Peizhou -- Jiang, Xuanting -- Li, Juan -- Fan, Dingding -- Wang, Wei -- Fu, Wenjing -- Wang, Tong -- Wang, Bo -- Zhang, Jibiao -- Peng, Zhiyu -- Li, Yingxiang -- Li, Na -- Wang, Jinpeng -- Chen, Maoshan -- He, Yan -- Tan, Fengji -- Song, Xiaorui -- Zheng, Qiumei -- Huang, Ronglian -- Yang, Hailong -- Du, Xuedi -- Chen, Li -- Yang, Mei -- Gaffney, Patrick M -- Wang, Shan -- Luo, Longhai -- She, Zhicai -- Ming, Yao -- Huang, Wen -- Zhang, Shu -- Huang, Baoyu -- Zhang, Yong -- Qu, Tao -- Ni, Peixiang -- Miao, Guoying -- Wang, Junyi -- Wang, Qiang -- Steinberg, Christian E W -- Wang, Haiyan -- Li, Ning -- Qian, Lumin -- Zhang, Guojie -- Li, Yingrui -- Yang, Huanming -- Liu, Xiao -- Wang, Jian -- Yin, Ye -- Wang, Jun -- 268513/European Research Council/International -- England -- Nature. 2012 Oct 4;490(7418):49-54. doi: 10.1038/nature11413.

    Description: Pluripotency, the ability to generate any cell type of the body, is an evanescent attribute of embryonic cells. Transitory pluripotent cells can be captured at different time points during embryogenesis and maintained as embryonic stem cells or epiblast stem cells in culture. Since ontogenesis is a dynamic process in both space and time, it seems counterintuitive that these two temporal states represent the full spectrum of organismal pluripotency. Here we show that by modulating culture parameters, a stem-cell type with unique spatial characteristics and distinct molecular and functional features, designated as region-selective pluripotent stem cells (rsPSCs), can be efficiently obtained from mouse embryos and primate pluripotent stem cells, including humans. The ease of culturing and editing the genome of human rsPSCs offers advantages for regenerative medicine applications. The unique ability of human rsPSCs to generate post-implantation interspecies chimaeric embryos may facilitate our understanding of early human development and evolution.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wu, Jun -- Okamura, Daiji -- Li, Mo -- Suzuki, Keiichiro -- Luo, Chongyuan -- Ma, Li -- He, Yupeng -- Li, Zhongwei -- Benner, Chris -- Tamura, Isao -- Krause, Marie N -- Nery, Joseph R -- Du, Tingting -- Zhang, Zhuzhu -- Hishida, Tomoaki -- Takahashi, Yuta -- Aizawa, Emi -- Kim, Na Young -- Lajara, Jeronimo -- Guillen, Pedro -- Campistol, Josep M -- Esteban, Concepcion Rodriguez -- Ross, Pablo J -- Saghatelian, Alan -- Ren, Bing -- Ecker, Joseph R -- Izpisua Belmonte, Juan Carlos -- Howard Hughes Medical Institute/ -- England -- Nature. 2015 May 21;521(7552):316-21. doi: 10.1038/nature14413.

    Description: Abscisic acid (ABA) is an essential hormone for plants to survive environmental stresses. At the center of the ABA signaling network is a subfamily of type 2C protein phosphatases (PP2Cs), which form exclusive interactions with ABA receptors and subfamily 2 Snfl-related kinase (SnRK2s). Here, we report a SnRK2-PP2C complex structure, which reveals marked similarity in PP2C recognition by SnRK2 and ABA receptors. In the complex, the kinase activation loop docks into the active site of PP2C, while the conserved ABA-sensing tryptophan of PP2C inserts into the kinase catalytic cleft, thus mimicking receptor-PP2C interactions. These structural results provide a simple mechanism that directly couples ABA binding to SnRK2 kinase activation and highlight a new paradigm of kinase-phosphatase regulation through mutual packing of their catalytic sites.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3584687/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3584687/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Soon, Fen-Fen -- Ng, Ley-Moy -- Zhou, X Edward -- West, Graham M -- Kovach, Amanda -- Tan, M H Eileen -- Suino-Powell, Kelly M -- He, Yuanzheng -- Xu, Yong -- Chalmers, Michael J -- Brunzelle, Joseph S -- Zhang, Huiming -- Yang, Huaiyu -- Jiang, Hualiang -- Li, Jun -- Yong, Eu-Leong -- Cutler, Sean -- Zhu, Jian-Kang -- Griffin, Patrick R -- Melcher, Karsten -- Xu, H Eric -- GM084041/GM/NIGMS NIH HHS/ -- R01 GM059138/GM/NIGMS NIH HHS/ -- S10 RR027270/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2012 Jan 6;335(6064):85-8. doi: 10.1126/science.1215106.
