Description: Plant-specific TCP domain transcription factors have been shown to regulate morphological novelties during plant evolution, including the complex architecture of the Asteraceae inflorescence that involves different types of flowers. We conducted comparative analysis of the CYCLOIDEA/TEOSINTE BRANCHED1 ( CYC/TB1 ) gene family in Gerbera hybrida (gerbera) and Helianthus annuus (sunflower), two species that represent distant tribes within Asteraceae. Our data confirm that the CYC/TB1 gene family has expanded in Asteraceae, a condition that appears to be connected with the increased developmental complexity and evolutionary success of this large plant family. Phylogenetic analysis of the CYC/TB1 gene family revealed both shared and lineage-specific duplications in gerbera and sunflower, corresponding to the three gene lineages previously identified as specific to core eudicots: CYC1, CYC2, and CYC3. Expression analyses of early stages of flower primordia development indicated that especially within the CYC2 clade, with the greatest number of secondary gene duplications, gene expression patterns are conserved between the species and associated with flower and inflorescence development. All sunflower and gerbera CYC2 clade genes showed differential expression between developing flower types, being upregulated in marginal ray (and trans) flowers. One gene in gerbera ( GhCYC3 ) and two in sunflower ( HaCYC2d and HaCYC2c ) were indicated to be strong candidates as regulators of ray flower identity, a function that is specific for Asteraceae. Our data further showed that other CYC2 clade genes are likely to have more specialized functions at the level of single flowers, including the late functions in floral reproductive organs that may be more conserved across plant families. The expression patterns of CYC1 and CYC3 clade genes showed more differences between the two species but still pointed to possible conserved functions during vegetative plant development. Pairwise protein–protein interaction assays gave the first molecular evidence that CYC/TB1-like proteins function in complexes. Compared with sunflower, the gerbera proteins showed higher capacity for dimerization, between as well as within CYC clades. Our data from two distant species within the Asteraceae suggest that the expansion and the apparent conservation of especially the CYC2 clade CYC/TB1 -like genes are associated with the evolution of the increased complexity of the Asteraceae inflorescence architecture.

Description: The origin and rapid diversification of the angiosperms (Darwin's “Abominable Mystery”) has engaged generations of researchers. Here, we examine the floral genetic programs of phylogenetically pivotal angiosperms (water lily, avocado, California poppy, and Arabidopsis) and a nonflowering seed plant (a cycad) to obtain insight into the origin and subsequent evolution of the flower. Transcriptional cascades with broadly overlapping spatial domains, resembling the hypothesized ancestral gymnosperm program, are deployed across morphologically intergrading organs in water lily and avocado flowers. In contrast, spatially discrete transcriptional programs in distinct floral organs characterize the more recently derived angiosperm lineages represented by California poppy and Arabidopsis. Deep evolutionary conservation in the genetic programs of putatively homologous floral organs traces to those operating in gymnosperm reproductive cones. Female gymnosperm cones and angiosperm carpels share conserved genetic features, which may be associated with the ovule developmental program common to both organs. However, male gymnosperm cones share genetic features with both perianth (sterile attractive and protective) organs and stamens, supporting the evolutionary origin of the floral perianth from the male genetic program of seed plants.

Description: The carnivorous habit in flowering plants represents a grade of structural organization. Different morphological features associated with the attraction, trapping, and digestion of prey characterize a diversity of specialized forms, including the familiar pitcher and flypaper traps. Phylogenetic analysis of nucleotide sequence data from the plastic rbcL gene indicates that both carnivory and stereotyped trap forms have arisen independently in different lineages of angiosperms. Furthermore, these results demonstrate that flypaper traps share close common ancestry with all other trap forms. Recognition of these patterns of diversification may provide ideal, naturally occurring systems for studies of developmental processes underlying macromorphological evolution in angiosperms.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Albert, V A -- Williams, S E -- Chase, M W -- New York, N.Y. -- Science. 1992 Sep 11;257(5076):1491-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1523408" target="_blank"〉PubMed〈/a〉

Description: Vascular plants appeared ~410 million years ago, then diverged into several lineages of which only two survive: the euphyllophytes (ferns and seed plants) and the lycophytes. We report here the genome sequence of the lycophyte Selaginella moellendorffii (Selaginella), the first nonseed vascular plant genome reported. By comparing gene content in evolutionarily diverse taxa, we found that the transition from a gametophyte- to a sporophyte-dominated life cycle required far fewer new genes than the transition from a nonseed vascular to a flowering plant, whereas secondary metabolic genes expanded extensively and in parallel in the lycophyte and angiosperm lineages. Selaginella differs in posttranscriptional gene regulation, including small RNA regulation of repetitive elements, an absence of the trans-acting small interfering RNA pathway, and extensive RNA editing of organellar genes.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3166216/" 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/PMC3166216/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Banks, Jo Ann -- Nishiyama, Tomoaki -- Hasebe, Mitsuyasu -- Bowman, John L -- Gribskov, Michael -- dePamphilis, Claude -- Albert, Victor A -- Aono, Naoki -- Aoyama, Tsuyoshi -- Ambrose, Barbara A -- Ashton, Neil W -- Axtell, Michael J -- Barker, Elizabeth -- Barker, Michael S -- Bennetzen, Jeffrey L -- Bonawitz, Nicholas D -- Chapple, Clint -- Cheng, Chaoyang -- Correa, Luiz Gustavo Guedes -- Dacre, Michael -- DeBarry, Jeremy -- Dreyer, Ingo -- Elias, Marek -- Engstrom, Eric M -- Estelle, Mark -- Feng, Liang -- Finet, Cedric -- Floyd, Sandra K -- Frommer, Wolf B -- Fujita, Tomomichi -- Gramzow, Lydia -- Gutensohn, Michael -- Harholt, Jesper -- Hattori, Mitsuru -- Heyl, Alexander -- Hirai, Tadayoshi -- Hiwatashi, Yuji -- Ishikawa, Masaki -- Iwata, Mineko -- Karol, Kenneth G -- Koehler, Barbara -- Kolukisaoglu, Uener -- Kubo, Minoru -- Kurata, Tetsuya -- Lalonde, Sylvie -- Li, Kejie -- Li, Ying -- Litt, Amy -- Lyons, Eric -- Manning, Gerard -- Maruyama, Takeshi -- Michael, Todd P -- Mikami, Koji -- Miyazaki, Saori -- Morinaga, Shin-ichi -- Murata, Takashi -- Mueller-Roeber, Bernd -- Nelson, David R -- Obara, Mari -- Oguri, Yasuko -- Olmstead, Richard G -- Onodera, Naoko -- Petersen, Bent Larsen -- Pils, Birgit -- Prigge, Michael -- Rensing, Stefan A -- Riano-Pachon, Diego Mauricio -- Roberts, Alison W -- Sato, Yoshikatsu -- Scheller, Henrik Vibe -- Schulz, Burkhard -- Schulz, Christian -- Shakirov, Eugene V -- Shibagaki, Nakako -- Shinohara, Naoki -- Shippen, Dorothy E -- Sorensen, Iben -- Sotooka, Ryo -- Sugimoto, Nagisa -- Sugita, Mamoru -- Sumikawa, Naomi -- Tanurdzic, Milos -- Theissen, Gunter -- Ulvskov, Peter -- Wakazuki, Sachiko -- Weng, Jing-Ke -- Willats, William W G T -- Wipf, Daniel -- Wolf, Paul G -- Yang, Lixing -- Zimmer, Andreas D -- Zhu, Qihui -- Mitros, Therese -- Hellsten, Uffe -- Loque, Dominique -- Otillar, Robert -- Salamov, Asaf -- Schmutz, Jeremy -- Shapiro, Harris -- Lindquist, Erika -- Lucas, Susan -- Rokhsar, Daniel -- Grigoriev, Igor V -- GM065383/GM/NIGMS NIH HHS/ -- GM84051/GM/NIGMS NIH HHS/ -- HG004164/HG/NHGRI NIH HHS/ -- R01 GM043644/GM/NIGMS NIH HHS/ -- R01 GM084051/GM/NIGMS NIH HHS/ -- R01 GM084051-01A1/GM/NIGMS NIH HHS/ -- R01 HG004164/HG/NHGRI NIH HHS/ -- R01 HG004164-02/HG/NHGRI NIH HHS/ -- R01 HG004164-03/HG/NHGRI NIH HHS/ -- R01 HG004164-04/HG/NHGRI NIH HHS/ -- T32 GM007757/GM/NIGMS NIH HHS/ -- T32-HG00035/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2011 May 20;332(6032):960-3. doi: 10.1126/science.1203810.

Description: Genome sequencing with next-generation sequence (NGS) technologies can now be applied to organisms pivotal to addressing fundamental biological questions, but with genomes previously considered intractable or too expensive to undertake. However, for species with large and complex genomes, extensive genetic and physical map resources have, until now, been required to direct the sequencing effort and sequence assembly. As these resources are unavailable for most species, assembling high-quality genome sequences from NGS data remains challenging. We describe a strategy that uses NGS, fluorescence in situ hybridization, and whole-genome mapping to assemble a high-quality genome sequence for Amborella trichopoda, a nonmodel species crucial to understanding flowering plant evolution. These methods are applicable to many other organisms with limited genomic resources.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chamala, Srikar -- Chanderbali, Andre S -- Der, Joshua P -- Lan, Tianying -- Walts, Brandon -- Albert, Victor A -- dePamphilis, Claude W -- Leebens-Mack, Jim -- Rounsley, Steve -- Schuster, Stephan C -- Wing, Rod A -- Xiao, Nianqing -- Moore, Richard -- Soltis, Pamela S -- Soltis, Douglas E -- Barbazuk, W Brad -- New York, N.Y. -- Science. 2013 Dec 20;342(6165):1516-7. doi: 10.1126/science.1241130.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, University of Florida, Gainesville, FL 32611, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24357320" target="_blank"〉PubMed〈/a〉

Description: Coffee is a valuable beverage crop due to its characteristic flavor, aroma, and the stimulating effects of caffeine. We generated a high-quality draft genome of the species Coffea canephora, which displays a conserved chromosomal gene order among asterid angiosperms. Although it shows no sign of the whole-genome triplication identified in Solanaceae species such as tomato, the genome includes several species-specific gene family expansions, among them N-methyltransferases (NMTs) involved in caffeine production, defense-related genes, and alkaloid and flavonoid enzymes involved in secondary compound synthesis. Comparative analyses of caffeine NMTs demonstrate that these genes expanded through sequential tandem duplications independently of genes from cacao and tea, suggesting that caffeine in eudicots is of polyphyletic origin.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Denoeud, France -- Carretero-Paulet, Lorenzo -- Dereeper, Alexis -- Droc, Gaetan -- Guyot, Romain -- Pietrella, Marco -- Zheng, Chunfang -- Alberti, Adriana -- Anthony, Francois -- Aprea, Giuseppe -- Aury, Jean-Marc -- Bento, Pascal -- Bernard, Maria -- Bocs, Stephanie -- Campa, Claudine -- Cenci, Alberto -- Combes, Marie-Christine -- Crouzillat, Dominique -- Da Silva, Corinne -- Daddiego, Loretta -- De Bellis, Fabien -- Dussert, Stephane -- Garsmeur, Olivier -- Gayraud, Thomas -- Guignon, Valentin -- Jahn, Katharina -- Jamilloux, Veronique -- Joet, Thierry -- Labadie, Karine -- Lan, Tianying -- Leclercq, Julie -- Lepelley, Maud -- Leroy, Thierry -- Li, Lei-Ting -- Librado, Pablo -- Lopez, Loredana -- Munoz, Adriana -- Noel, Benjamin -- Pallavicini, Alberto -- Perrotta, Gaetano -- Poncet, Valerie -- Pot, David -- Priyono -- Rigoreau, Michel -- Rouard, Mathieu -- Rozas, Julio -- Tranchant-Dubreuil, Christine -- VanBuren, Robert -- Zhang, Qiong -- Andrade, Alan C -- Argout, Xavier -- Bertrand, Benoit -- de Kochko, Alexandre -- Graziosi, Giorgio -- Henry, Robert J -- Jayarama -- Ming, Ray -- Nagai, Chifumi -- Rounsley, Steve -- Sankoff, David -- Giuliano, Giovanni -- Albert, Victor A -- Wincker, Patrick -- Lashermes, Philippe -- New York, N.Y. -- Science. 2014 Sep 5;345(6201):1181-4. doi: 10.1126/science.1255274.

Description: It has been argued that the evolution of plant genome size is principally unidirectional and increasing owing to the varied action of whole-genome duplications (WGDs) and mobile element proliferation. However, extreme genome size reductions have been reported in the angiosperm family tree. Here we report the sequence of the 82-megabase genome of the carnivorous bladderwort plant Utricularia gibba. Despite its tiny size, the U. gibba genome accommodates a typical number of genes for a plant, with the main difference from other plant genomes arising from a drastic reduction in non-genic DNA. Unexpectedly, we identified at least three rounds of WGD in U. gibba since common ancestry with tomato (Solanum) and grape (Vitis). The compressed architecture of the U. gibba genome indicates that a small fraction of intergenic DNA, with few or no active retrotransposons, is sufficient to regulate and integrate all the processes required for the development and reproduction of a complex organism.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ibarra-Laclette, Enrique -- Lyons, Eric -- Hernandez-Guzman, Gustavo -- Perez-Torres, Claudia Anahi -- Carretero-Paulet, Lorenzo -- Chang, Tien-Hao -- Lan, Tianying -- Welch, Andreanna J -- Juarez, Maria Jazmin Abraham -- Simpson, June -- Fernandez-Cortes, Araceli -- Arteaga-Vazquez, Mario -- Gongora-Castillo, Elsa -- Acevedo-Hernandez, Gustavo -- Schuster, Stephan C -- Himmelbauer, Heinz -- Minoche, Andre E -- Xu, Sen -- Lynch, Michael -- Oropeza-Aburto, Araceli -- Cervantes-Perez, Sergio Alan -- de Jesus Ortega-Estrada, Maria -- Cervantes-Luevano, Jacob Israel -- Michael, Todd P -- Mockler, Todd -- Bryant, Douglas -- Herrera-Estrella, Alfredo -- Albert, Victor A -- Herrera-Estrella, Luis -- 4367/Howard Hughes Medical Institute/ -- England -- Nature. 2013 Jun 6;498(7452):94-8. doi: 10.1038/nature12132.
