Phylogenetic Relationships Among the One-Flowered, Determinate Genera of Bambuseae (Poaceae: Bambusoideae)

Abstract

Bambuseae (woody bamboos), one of two tribes recognized within Bambusoideae (true bamboos), comprise over 90% of the diversity of the subfamily, yet monophyly of the tribe is generally only moderately supported, and phylogenetic relationships within the tribe are poorly understood. In addition, there appears to be some level of conflict between morphological and molecular data within the tribe. We conducted a parsimony analysis of 43 species of Bambuseae, three of Olyreae (herbaceous bamboos), and two outgroup taxa using morphological and plastid rpl16 intron sequence data to (1) further test the monophyly of Bambuseae, (2) test the monophyly of Chusqueinae and Hickelinae (the two one-flowered, determinate subtribes), and (3) examine the apparent conflict between molecular and morphological data sets in the determinate, one-flowered genera of Bambuseae. We recovered a monophyletic Bambusoideae, Bambuseae, Olyreae, and Chusqueinae, although support for Bambuseae remained moderate. Our results suggest that the morphological similarities between Chusqueinae and Hickelinae are homoplasious, but robust resolution of relationships among the major lineages of woody bamboos is still wanting.

Phylogeny of the Grasses (Poaceae) Revisited

“…Sequence determination followed standard methods (Clark et al 1995;Duvall and Morton 1996). GenBank accession numbers for the complete set of sequences analyzed, together with voucher specimen information for newly determined sequences, are provided in Table 2.…”

Revisão taxonômica e análise filogenética de espécies de Aponychus Rimando, Praponychus Gonzáles & Flechtmann e Stylophoronychus Prasad (Acari, Eurytetranychini)

“…A filogenia dos hospedeiros foi retirada de diversos autores sumarizados por Davies et al (2004) para as plantas mono e dicotiledôneas, e dos trabalhos de Hilu et al (1999), Clark et al (1995Clark et al ( , 2007, Giussani et al (2001) Dessas, 21 são da subfamília Bambusoideae, tribo Bambuseae, que apresenta cerca de 1.400 espécies de bambús verdadeiros, ou "woody bamboos" (Clark et al, 2007 (Zhang et al, 2000), sendo provável que essa espécie, descrita a partir de uma única fêmea coletada sobre uma dicotiledônea, Aponychus spinosus é a espécie do grupo estudado com a maior amplitude de distribuição geográfica já registrada, descrita da região sudeste do Canadá (Banks, 1909), e já coletada em diversas localidades da América do Sul (Aranda & Flechtmann, 1971, Paschoal, 1969, América do Norte (Baker & Tuttle, 1994) e em uma única localidade na Ásia, nas Filipinas (Thewke & Enns, 1969). Próximo a essa última região, na China, ocorre uma outra espécie bastante semelhante, Aponychus taishanicus Wang, 1980 que também apresenta as setas dorsais bastante longas, com a possibilidade de que o registro de A. spinosus nas Filipinas seja, na realidade, de A.…”

Proposal for qualitative and quantitative descriptors to or characterise bamboo germplasm

“…Most current classifications of the bamboo depend on morphological characteristics (CLARK et al, 2007), however few species have been properly documented, making it difficult to use phenotypic features. This is further compounded by the fact that taxonomic studies traditionally depend on inflorescence and floral morphology, since vegetative characteristics can be influenced by environmental conditions (SHALINI et al, 2013;YEASMIN et al, 2015).…”
