Received 5 February 2015; Accepted 25 February 2015; Article first published online 23 March 2015 Abstract Based on recent molecular and morphological studies we present a modern worldwide phylogenetic classification of the Æ 12074 grasses and place the 771 grass genera into 12 subfamilies (Anomochlooideae, Aristidoideae, Arundinoideae, Bambusoideae, Chloridoideae, Danthonioideae, Micraioideae, Oryzoideae, Panicoi- deae, Pharoideae, Puelioideae, and Pooideae), 6 supertribes (Andropogonodae, Arundinarodae, Bambusodae, Panicodae, Poodae, Triticodae), 51 tribes (Ampelodesmeae, Andropogoneae, Anomochloeae, Aristideae, Arundinarieae, Arundineae, Arundinelleae, Atractocarpeae, Bambuseae, Brachyelytreae, Brachypodieae, Bromeae, Brylkinieae, Centotheceae, Centropodieae, Chasmanthieae, Cynodonteae, Cyperochloeae, Danthonieae, Diarrhe- neae, Ehrharteae, Eragrostideae, Eriachneae, Guaduellieae, Gynerieae, Hubbardieae, Isachneae, Littledaleeae, Lygeeae, Meliceae, Micraireae, Molinieae, Nardeae, Olyreae, Oryzeae, Paniceae, Paspaleae, Phaenospermateae, Phareae, Phyllorachideae, Poeae, Steyermarkochloeae, Stipeae, Streptochaeteae, Streptogyneae, Thysanolaeneae, Triraphideae, Tristachyideae, Triticeae, Zeugiteae, and Zoysieae), and 80 subtribes (Aeluropodinae, Agrostidinae, Airinae, Ammochloinae, Andropogoninae, Anthephorinae, Anthistiriinae, Anthoxanthinae, Arthraxoninae, Arthro- pogoninae, Arthrostylidiinae, Arundinariinae, Aveninae, Bambusinae, Boivinellinae, Boutelouinae, Brizinae, Buergersiochloinae, Calothecinae, Cenchrinae, Chionachninae, Chusqueinae, Coicinae, Coleanthinae, Cotteinae, Cteniinae, Cynosurinae, Dactylidinae, Dichantheliinae, Dimeriinae, Duthieinae, Eleusininae, Eragrostidinae, Farragininae, Germainiinae, Gouiniinae, Guaduinae, Gymnopogoninae, Hickeliinae, Hilariinae, Holcinae, Hordeinae, Ischaeminae, Loliinae, Melinidinae, Melocanninae, Miliinae, Monanthochloinae, Muhlenbergiinae, Neurachninae, Olyrinae, Orcuttiinae, Oryzinae, Otachyriinae, Panicinae, Pappophorinae, Parapholiinae, Parianinae, Paspalinae, Perotidinae, Phalaridinae, Poinae, Racemobambosinae, Rottboelliinae, Saccharinae, Scleropogoninae, Scolochloi- nae, Sesleriinae, Sorghinae, Sporobolinae, Torreyochloinae, Traginae, Trichoneurinae, Triodiinae, Tripogoninae, Tripsacinae, Triticinae, Unioliinae, Zizaniinae, and Zoysiinae). In addition, we include a radial tree illustrating the hierarchical relationships among the subtribes, tribes, and subfamilies. We use the subfamilial name, Oryzoideae, over Ehrhartoideae because the latter was initially published as a misplaced rank, and we circumscribe Molinieae to include 13 Arundinoideae genera. The subtribe Calothecinae is newly described and the tribe Littledaleeae is new at that rank. Key words: classification, DNA, Gramineae, grasses, morphology, phylogeny, Poaceae, subfamily, subtribe, tribe. In 1991, most of the authors of this paper attended the 42nd Ehrhartoideae, and Pharoideae was published (Judziewicz American Institute of Biological Sciences Annual Meeting in et al., 2000). Subsequently, the Chloridoideae (Peterson et al., San Antonio, Texas to discuss the possibility of creating a large 2001), Pooideae (Soreng et al., 2003), and the Panicoideae, digital database that would include nomenclature, taxonomy, Aristidoideae, Arundinoideae, and Danthonioideae (Zuloaga synonymy, original publications, type collections, secondary et al., 2003) were printed. Within each of these, provisional references using accepted names, and distribution by country but now woefully out of date treatments, we included our of all New World grasses. Nine years later the first hard copy best estimate of the generic classification of the tribes and treatment of subfamilies Anomochlooideae, Bambusoideae, subtribes for each subfamily.

    Revista Brasileira de Biociências Brazilian Journal of Biosciences http://www.ufrgs.br/seerbio/ojs ISSN 1980-4849 (on-line) / 1679-2343 (print) ARTICLE Floristic and characterization of grassland vegetation at a granitic hill in Southern Brazil Robberson Bernal Setubal1* and Ilsi Iob Boldrini2 Received: March 31 2009 Received after revision: November 19 2009 Accepted: November 20 2009 Available online at http://www.ufrgs.br/seerbio/ojs/index.php/rbb/article/view/1209 ABSTRACT: (Floristic and characterization of grasslands vegetation of a granite hill in Southern Brazil). A floristic and vegeta- tion study was carried out in the grassland formations at Morro São Pedro, Porto Alegre municipality, Rio Grande do Sul State, a granitic elevation area, so far poorly surveyed, that cradles important natural vegetation remnants of the region. After the study, which lasted from April 2005 to March 2009, we found 497 angiosperm species, distributed in four main grassland formation types: dry grassland, rocky grassland, humid grassland and wetlands. Among the species list three species are noteworthy: Alstroemeria albescens, a new species for the science, Lepuropethalon spathulatum, a new record for Southern Brazil, and Thrasyopsis juergensii, a new record for the Pampa biome. Based on our results and on support from other papers we concluded that ca. 65% of the grassland species present in the granitic hills of the region belong to seven main botanical families (Astera- ceae, Poaceae, Fabaceae, Cyperaceae, Rubiaceae, Verbenaceae and Apiaceae). The species belonging to these families are also determining in the vegetation phytophysiognomical and structural composition, so that cespitous grasses predominate in the landscape, shaping a continuous gramineous layer.

Carretera antigua a Coatepec 351, Xalapa, 91070, Mexico., e-mail: [email protected] *author for correspondence Abstract With 52 described species, Merostachys is the most diverse genus in the Arthrostylidiinae; 50 of the species are present in South America and only two, M. latifolia and M. pauciflora, are distributed in Central America and Mexico. Previous col- lections of vegetative Merostachys specimens from El Triunfo, Chiapas, Mexico, were identified as M. pauciflora. However, new flowering collections from the state of Tabasco, Mexico, allowed us to differentiate the Mexican populations from M. latifolia and M. pauciflora. A detailed study of samples from the Tabasco population, and a review of the previous collections from Chiapas, confirmed the existence of a new Merostachys species, which we here describe and illustrate as M.

Accepted 23 September, 2010 Aegilops vavilovii (Zhuk.) Chennav., a rare species, was collected from Southeast Anatolia, Turkey. During the field studies of the project “Taxonomic revision of Tribe Triticeae in Turkey”, Ae. vavilovii was accidentally recollected from three localities in anliurfa and Mardin provinces in 2007 and 2008, respectively. The main objective of this study is to shed light on the diagnostic characteristics of this rare species including its morphological, palynological and micro morphological features. Moreover, an emended and expanded description, distribution, phenology and ecology of this rare species are also provided. A. vavilovii and A. crassa are naturally found in the Southeastern part of Turkey and they share similar morphological features that caused a confused taxonomy. Pollen grains of A. vavilovii are heteropolar, monoporate and spheroidal (A/B: 1,13) typically as Poaceous. However, it generally, prefers clayish loam soils that are slightly alkaline (pH 7.7) with low organic content (1.54%). Although it is a rare species with very narrow area of distribution, very few samples have been represented in ex situ collections and the species has not been involved in any in situ conservation activities to save its genetic resources in Turkey.

It is a predominantly flat land with several shallow depressions, which act as seasonal wetlands after monsoon and during winter its converts into sedge mixed grassland, an ideal dual ecosystem. An attempt was made to document ecology, biomass and community based assessment of grasses in Banni, we surveyed systematically and recorded a total of 49 herbaceous plant species, being used as fodder by livestock. In which, the maximum numbers of species (21 Nos.) were recorded in Echinocloa and Cressa habitat; followed by Sporobolus and Elussine habitat (20 species); and Desmostechia-Aeluropus and Cressa habiat (19 species). A total of 21 highest palatable species were recorded in Echinocloa-Cressa communities followed by Sporobolus-Elussine–Desmostechia (20 species and 18 palatable species) and Aeluropus–Cressa (19 species and 17 palatable species). For long-term conservation of Banni grassland, we also suggest a participatory co-management plan.

Recent studies have shown that, the expression levels of common housekeeping genes are varying in different tissues and experimental conditions. The genomic DNA contamination in RNA samples is another important factor that also influence the interpretation of the data obtained from qPCR. It is estimated that the gDNA contamination in gene expression analysis lead to an overes- timation of the RNA transcript level. The aim of this study was to validate the most stably expressed reference genes in two different tissues of Aeluropus littoralis—halophyte grass at salt stress and recovery condition. Also, a qPCR-based approach for monitoring contamination with gDNA was conducted. Results: Ten candidate reference genes participating in different biological processes were analyzed in four groups of samples including root and leaf tissues, salt stress and recovery condition. To determine the most stably expressed reference genes, three statistical methods (geNorm, NormFinder and BestKeeper) were applied. According to results obtained, ten candidate reference genes were ranked based on the stability of their expression.

El objetivo principal de este estudio fue actualizar la lista de taxa en México, reuniendo el mayor número posible de bases de datos en línea. Otros objetivos incluyeron la comparación de la riqueza de especies de la familia Poaceae entre los países con mayor diversidad, así como analizar la riqueza de sus taxa a nivel estatal y por categorías taxonómicas. Métodos: Se consultaron bases de datos en línea, tanto nacionales como extranjeras, que incluían ejemplares de referencia de México, se descarga- ron y se curaron, además de una confirmación visual de la identidad de un gran porcentaje de ejemplares. Se extrajeron los nombres de las especies, estados donde fueron colectadas y los acrónimos de los herbarios. La base resultante se complementó solo con bibliografía a partir de 2006 y la no incluida en el catálogo que mostraba ejemplares de respaldo. Resultados clave: Se revisaron 227,973 registros que contabilizaron, en total, 1416 taxa, que incluyen 215 géneros, 1312 especies y 214 categorías infraespecíficas. Del total de especies, 1092 se consideran nativas y 224 introducidas (cultivadas y/o malezas). Las especies endémicas de México son 304 (27.83%) o 311 (28.10%) si se consideran categorías inferiores.
