    Beschreibung: The nematode pharynx has a potassium channel with unusual properties, which allows the muscles to repolarize quickly and with the proper delay. Here, the Caenorhabditis elegans exp-2 gene is shown to encode this channel. EXP-2 is a Kv-type (voltage-activated) potassium channel that has inward-rectifying properties resembling those of the structurally dissimilar human ether-a-go-go-related gene (HERG) channel. Null and gain-of-function mutations affect pharyngeal muscle excitability in ways that are consistent with the electrophysiological behavior of the channel, and thereby demonstrate a direct link between the kinetics of this unusual channel and behavior.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3791429/" 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/PMC3791429/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Davis, M W -- Fleischhauer, R -- Dent, J A -- Joho, R H -- Avery, L -- HL46154/HL/NHLBI NIH HHS/ -- NS28407/NS/NINDS NIH HHS/ -- R01 HL046154/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1999 Dec 24;286(5449):2501-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biology, University of Texas Southwestern Medical Center, Dallas, TX 75390-9148, USA. wdavis@biology.utah.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10617464" target="_blank"〉PubMed〈/a〉

    Beschreibung: Tree taxa shifted latitude or elevation range in response to changes in Quaternary climate. Because many modern trees display adaptive differentiation in relation to latitude or elevation, it is likely that ancient trees were also so differentiated, with environmental sensitivities of populations throughout the range evolving in conjunction with migrations. Rapid climate changes challenge this process by imposing stronger selection and by distancing populations from environments to which they are adapted. The unprecedented rates of climate changes anticipated to occur in the future, coupled with land use changes that impede gene flow, can be expected to disrupt the interplay of adaptation and migration, likely affecting productivity and threatening the persistence of many species.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Davis, M B -- Shaw, R G -- New York, N.Y. -- Science. 2001 Apr 27;292(5517):673-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ecology, Evolution and Behavior, University of Minnesota, Saint Paul, MN 55108, USA. mbdavis@ecology.umn.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11326089" target="_blank"〉PubMed〈/a〉

    Beschreibung: Functional analysis of a genome requires accurate gene structure information and a complete gene inventory. A dual experimental strategy was used to verify and correct the initial genome sequence annotation of the reference plant Arabidopsis. Sequencing full-length cDNAs and hybridizations using RNA populations from various tissues to a set of high-density oligonucleotide arrays spanning the entire genome allowed the accurate annotation of thousands of gene structures. We identified 5817 novel transcription units, including a substantial amount of antisense gene transcription, and 40 genes within the genetically defined centromeres. This approach resulted in completion of approximately 30% of the Arabidopsis ORFeome as a resource for global functional experimentation of the plant proteome.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yamada, Kayoko -- Lim, Jun -- Dale, Joseph M -- Chen, Huaming -- Shinn, Paul -- Palm, Curtis J -- Southwick, Audrey M -- Wu, Hank C -- Kim, Christopher -- Nguyen, Michelle -- Pham, Paul -- Cheuk, Rosa -- Karlin-Newmann, George -- Liu, Shirley X -- Lam, Bao -- Sakano, Hitomi -- Wu, Troy -- Yu, Guixia -- Miranda, Molly -- Quach, Hong L -- Tripp, Matthew -- Chang, Charlie H -- Lee, Jeong M -- Toriumi, Mitsue -- Chan, Marie M H -- Tang, Carolyn C -- Onodera, Courtney S -- Deng, Justine M -- Akiyama, Kenji -- Ansari, Yasser -- Arakawa, Takahiro -- Banh, Jenny -- Banno, Fumika -- Bowser, Leah -- Brooks, Shelise -- Carninci, Piero -- Chao, Qimin -- Choy, Nathan -- Enju, Akiko -- Goldsmith, Andrew D -- Gurjal, Mani -- Hansen, Nancy F -- Hayashizaki, Yoshihide -- Johnson-Hopson, Chanda -- Hsuan, Vickie W -- Iida, Kei -- Karnes, Meagan -- Khan, Shehnaz -- Koesema, Eric -- Ishida, Junko -- Jiang, Paul X -- Jones, Ted -- Kawai, Jun -- Kamiya, Asako -- Meyers, Cristina -- Nakajima, Maiko -- Narusaka, Mari -- Seki, Motoaki -- Sakurai, Tetsuya -- Satou, Masakazu -- Tamse, Racquel -- Vaysberg, Maria -- Wallender, Erika K -- Wong, Cecilia -- Yamamura, Yuki -- Yuan, Shiaulou -- Shinozaki, Kazuo -- Davis, Ronald W -- Theologis, Athanasios -- Ecker, Joseph R -- New York, N.Y. -- Science. 2003 Oct 31;302(5646):842-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Plant Gene Expression Center, Albany, CA 94710, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14593172" target="_blank"〉PubMed〈/a〉

    Beschreibung: Horizontal gene transfer (HGT) between sexually unrelated species has recently been documented for higher plants, but mechanistic explanations for HGTs have remained speculative. We show that a parasitic relationship may facilitate HGT between flowering plants. The endophytic parasites Rafflesiaceae are placed in the diverse order Malpighiales. Our multigene phylogenetic analyses of Malpighiales show that mitochondrial (matR) and nuclear loci (18S ribosomal DNA and PHYC) place Rafflesiaceae in Malpighiales, perhaps near Ochnaceae/Clusiaceae. Mitochondrial nad1B-C, however, groups them within Vitaceae, near their obligate host Tetrastigma. These discordant phylogenetic hypotheses strongly suggest that part of the mitochondrial genome in Rafflesiaceae was acquired via HGT from their hosts.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Davis, Charles C -- Wurdack, Kenneth J -- New York, N.Y. -- Science. 2004 Jul 30;305(5684):676-8.

    Beschreibung: The structure of the general transcription factor IIB (TFIIB) in a complex with RNA polymerase II reveals three features crucial for transcription initiation: an N-terminal zinc ribbon domain of TFIIB that contacts the "dock" domain of the polymerase, near the path of RNA exit from a transcribing enzyme; a "finger" domain of TFIIB that is inserted into the polymerase active center; and a C-terminal domain, whose interaction with both the polymerase and with a TATA box-binding protein (TBP)-promoter DNA complex orients the DNA for unwinding and transcription. TFIIB stabilizes an early initiation complex, containing an incomplete RNA-DNA hybrid region. It may interact with the template strand, which sets the location of the transcription start site, and may interfere with RNA exit, which leads to abortive initiation or promoter escape. The trajectory of promoter DNA determined by the C-terminal domain of TFIIB traverses sites of interaction with TFIIE, TFIIF, and TFIIH, serving to define their roles in the transcription initiation process.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bushnell, David A -- Westover, Kenneth D -- Davis, Ralph E -- Kornberg, Roger D -- AI21144/AI/NIAID NIH HHS/ -- GM49985/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2004 Feb 13;303(5660):983-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Structural Biology, Stanford University School of Medicine, Stanford, CA 94305-5126, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14963322" target="_blank"〉PubMed〈/a〉
