    Description: High-copy-number transposable elements comprise the majority of eukaryotic genomes where they are major contributors to gene and genome evolution. However, it remains unclear how a host genome can survive a rapid burst of hundreds or thousands of insertions because such bursts are exceedingly rare in nature and therefore difficult to observe in real time. In a previous study we reported that in a few rice strains the DNA transposon mPing was increasing its copy number by approximately 40 per plant per generation. Here we exploit the completely sequenced rice genome to determine 1,664 insertion sites using high-throughput sequencing of 24 individual rice plants and assess the impact of insertion on the expression of 710 genes by comparative microarray analysis. We find that the vast majority of transposable element insertions either upregulate or have no detectable effect on gene transcription. This modest impact reflects a surprising avoidance of exon insertions by mPing and a preference for insertion into 5' flanking sequences of genes. Furthermore, we document the generation of new regulatory networks by a subset of mPing insertions that render adjacent genes stress inducible. As such, this study provides evidence for models first proposed previously for the involvement of transposable elements and other repetitive sequences in genome restructuring and gene regulation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Naito, Ken -- Zhang, Feng -- Tsukiyama, Takuji -- Saito, Hiroki -- Hancock, C Nathan -- Richardson, Aaron O -- Okumoto, Yutaka -- Tanisaka, Takatoshi -- Wessler, Susan R -- England -- Nature. 2009 Oct 22;461(7267):1130-4. doi: 10.1038/nature08479.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Plant Biology, University of Georgia, Athens, Georgia 30602, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19847266" target="_blank"〉PubMed〈/a〉

    Description: The temporal and spatial patterns of anthocyanin pigmentation in the maize plant are determined by the presence or absence of the R protein product, a presumed transcriptional activator. At least 50 unique patterns of pigmentation, conditioned by members of the R gene family, have been described. In this study, microprojectiles were used to introduce into maize cells a vector containing the transcription unit from one of these genes (Lc) fused to a constitutive promoter. This chimeric gene induces cell autonomous pigmentation in tissues that are not normally pigmented by the Lc gene. As a reporter for gene expression studies in maize, R is unique because it can be quantified in living tissue simply by counting the number of pigmented cells following bombardment. R may also be useful as a visible marker for selecting stably transformed cell lineages that can give rise to transgenic plants.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ludwig, S R -- Bowen, B -- Beach, L -- Wessler, S R -- New York, N.Y. -- Science. 1990 Jan 26;247(4941):449-50.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17788612" target="_blank"〉PubMed〈/a〉

    Description: Miniature inverted repeat transposable elements (MITEs) are widespread in eukaryotic genomes, where they can attain high copy numbers despite a lack of coding capacity. However, little is known about how they originate and amplify. We performed a genome-wide screen of functional interactions between Stowaway MITEs and potential transposases in the rice genome and identified a transpositionally active MITE that possesses key properties that enhance transposition. Although not directly related to its autonomous element, the MITE has less affinity for the transposase than does the autonomous element but lacks a motif repressing transposition in the autonomous element. The MITE contains internal sequences that enhance transposition. These findings suggest that MITEs achieve high transposition activity by scavenging transposases encoded by distantly related and self-restrained autonomous elements.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yang, Guojun -- Nagel, Dawn Holligan -- Feschotte, Cedric -- Hancock, C Nathan -- Wessler, Susan R -- New York, N.Y. -- Science. 2009 Sep 11;325(5946):1391-4. doi: 10.1126/science.1175688.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Plant Biology, University of Georgia, Athens, GA 30602, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19745152" target="_blank"〉PubMed〈/a〉

    Description: We report an improved draft nucleotide sequence of the 2.3-gigabase genome of maize, an important crop plant and model for biological research. Over 32,000 genes were predicted, of which 99.8% were placed on reference chromosomes. Nearly 85% of the genome is composed of hundreds of families of transposable elements, dispersed nonuniformly across the genome. These were responsible for the capture and amplification of numerous gene fragments and affect the composition, sizes, and positions of centromeres. We also report on the correlation of methylation-poor regions with Mu transposon insertions and recombination, and copy number variants with insertions and/or deletions, as well as how uneven gene losses between duplicated regions were involved in returning an ancient allotetraploid to a genetically diploid state. These analyses inform and set the stage for further investigations to improve our understanding of the domestication and agricultural improvements of maize.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schnable, Patrick S -- Ware, Doreen -- Fulton, Robert S -- Stein, Joshua C -- Wei, Fusheng -- Pasternak, Shiran -- Liang, Chengzhi -- Zhang, Jianwei -- Fulton, Lucinda -- Graves, Tina A -- Minx, Patrick -- Reily, Amy Denise -- Courtney, Laura -- Kruchowski, Scott S -- Tomlinson, Chad -- Strong, Cindy -- Delehaunty, Kim -- Fronick, Catrina -- Courtney, Bill -- Rock, Susan M -- Belter, Eddie -- Du, Feiyu -- Kim, Kyung -- Abbott, Rachel M -- Cotton, Marc -- Levy, Andy -- Marchetto, Pamela -- Ochoa, Kerri -- Jackson, Stephanie M -- Gillam, Barbara -- Chen, Weizu -- Yan, Le -- Higginbotham, Jamey -- Cardenas, Marco -- Waligorski, Jason -- Applebaum, Elizabeth -- Phelps, Lindsey -- Falcone, Jason -- Kanchi, Krishna -- Thane, Thynn -- Scimone, Adam -- Thane, Nay -- Henke, Jessica -- Wang, Tom -- Ruppert, Jessica -- Shah, Neha -- Rotter, Kelsi -- Hodges, Jennifer -- Ingenthron, Elizabeth -- Cordes, Matt -- Kohlberg, Sara -- Sgro, Jennifer -- Delgado, Brandon -- Mead, Kelly -- Chinwalla, Asif -- Leonard, Shawn -- Crouse, Kevin -- Collura, Kristi -- Kudrna, Dave -- Currie, Jennifer -- He, Ruifeng -- Angelova, Angelina -- Rajasekar, Shanmugam -- Mueller, Teri -- Lomeli, Rene -- Scara, Gabriel -- Ko, Ara -- Delaney, Krista -- Wissotski, Marina -- Lopez, Georgina -- Campos, David -- Braidotti, Michele -- Ashley, Elizabeth -- Golser, Wolfgang -- Kim, HyeRan -- Lee, Seunghee -- Lin, Jinke -- Dujmic, Zeljko -- Kim, Woojin -- Talag, Jayson -- Zuccolo, Andrea -- Fan, Chuanzhu -- Sebastian, Aswathy -- Kramer, Melissa -- Spiegel, Lori -- Nascimento, Lidia -- Zutavern, Theresa -- Miller, Beth -- Ambroise, Claude -- Muller, Stephanie -- Spooner, Will -- Narechania, Apurva -- Ren, Liya -- Wei, Sharon -- Kumari, Sunita -- Faga, Ben -- Levy, Michael J -- McMahan, Linda -- Van Buren, Peter -- Vaughn, Matthew W -- Ying, Kai -- Yeh, Cheng-Ting -- Emrich, Scott J -- Jia, Yi -- Kalyanaraman, Ananth -- Hsia, An-Ping -- Barbazuk, W Brad -- Baucom, Regina S -- Brutnell, Thomas P -- Carpita, Nicholas C -- Chaparro, Cristian -- Chia, Jer-Ming -- Deragon, Jean-Marc -- Estill, James C -- Fu, Yan -- Jeddeloh, Jeffrey A -- Han, Yujun -- Lee, Hyeran -- Li, Pinghua -- Lisch, Damon R -- Liu, Sanzhen -- Liu, Zhijie -- Nagel, Dawn Holligan -- McCann, Maureen C -- SanMiguel, Phillip -- Myers, Alan M -- Nettleton, Dan -- Nguyen, John -- Penning, Bryan W -- Ponnala, Lalit -- Schneider, Kevin L -- Schwartz, David C -- Sharma, Anupma -- Soderlund, Carol -- Springer, Nathan M -- Sun, Qi -- Wang, Hao -- Waterman, Michael -- Westerman, Richard -- Wolfgruber, Thomas K -- Yang, Lixing -- Yu, Yeisoo -- Zhang, Lifang -- Zhou, Shiguo -- Zhu, Qihui -- Bennetzen, Jeffrey L -- Dawe, R Kelly -- Jiang, Jiming -- Jiang, Ning -- Presting, Gernot G -- Wessler, Susan R -- Aluru, Srinivas -- Martienssen, Robert A -- Clifton, Sandra W -- McCombie, W Richard -- Wing, Rod A -- Wilson, Richard K -- New York, N.Y. -- Science. 2009 Nov 20;326(5956):1112-5. doi: 10.1126/science.1178534.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Plant Genomics, Iowa State University, Ames, IA 50011, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19965430" target="_blank"〉PubMed〈/a〉

    Description: Mutations caused by the insertion of members of the Ac or Spm family of transposable elements result in a great diversity of phenotypes. With the cloning of the mutant genes and the characterization of their products, the mechanisms underlying phenotypic diversity are being deciphered. These mechanisms include (i) imprecise excision of transposable elements, which can result in the addition of amino acids to proteins; (ii) DNA methylation, which has been correlated with the activity of the element; (iii) transposase-mediated deletions within elements, which can inactivate an element or lead to a new unstable phenotype; and (iv) removal of transcribed elements from RNA, which can facilitate gene expression despite the insertion of elements into exons. An understanding of the behavior of the maize elements has provided clues to the function of cryptic elements in all maize genomes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wessler, S R -- GM32528/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1988 Oct 21;242(4877):399-405.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Botany Department, University of Georgia, Athens 30602.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2845581" target="_blank"〉PubMed〈/a〉

    Description: In some instances, insertion of maize transposable elements into exons does not result in the total loss of enzymatic activity. In other instances, messenger RNAs of wild-type size are encoded by genes known to contain the maize transposable element Dissociation (Ds) in exons. To understand how Ds is processed from RNA, a study was made of transcripts encoded by two alleles of the maize waxy (wx) gene containing Ds insertions in exon sequences. The analysis was carried out in strains where the Ds element could not excise from the wx gene. Despite insertions of 4.3- and 1.5-Ds elements, the predominant transcripts encoded by these two genes were wild type in size. For both alleles, DNA sequencing of complementary DNAs revealed that the Ds elements had been spliced in a similar manner. Splicing was accomplished by the utilization of multiple 5' donor splice sites in the Ds termini and a 3' acceptor site within the wx gene adjacent to the Ds element. The net effect in both cases was the removal of most of the Ds element from the messenger RNA.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wessler, S R -- Baran, G -- Varagona, M -- New York, N.Y. -- Science. 1987 Aug 21;237(4817):916-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3039661" target="_blank"〉PubMed〈/a〉
