“…Generally, DNA extraction procedures were from silica-gel-dried leaves (Chase and Hills 1991) or herbarium sheets as summarized by Fay et al (2000). A description of the amplification procedures for the seven loci can be found in the following references: rbcL , atpB , trnL-F (primers "c" and "f" of Taber let et al 1991, which include two regions, trnL intron and trnL-F intergenic spacer), matK (Johnson and Soltis 1994), ndhF (Pires and Sytsma 2002;McPherson et al submitted), and atp 1 (Davis et al 1998Stevenson et al 2000). GenBank numbers for rbcL, atpB, and trnL-F have been previously published Pireset al 2004).…”

Asparagales are a diverse monophyletic order that has numerous species (ca. 50% of monocots) including important crop plants such as Allium, Asparagus, and Vanilla, and a host of ornamentals such as irises, hyacinths, and orchids. Historically, Asparagales have been of interest partly because of their fascinating chromosomal evolution. We examine the evolutionary dynamics of Asparagales genomes in an updated phylogenetic framework that combines analyses of seven gene regions (atpl, atpB, matK, ndhF, rbcL, trnL intron, and trnL-F intergenic spacer) for 79 taxa of Asparagales and outgroups. Asparagales genomes are evolutionarily labile for many characters, including chromosome number and genome size. The history and causes of variation in chromosome number and genome size remain unclear, primarily because of the lack of data in small clades in the phylogenetic tree and the lack of comparative genetic maps, apart from Allium and Asparagus. Genomic tools such as bacterial artificial chromosome (BAC) libraries should be developed, as both molecular cytogenetic markers and a source of nuclear genes that can be widely used by evolutionary biologists and plant breeders alike to decipher mechanisms of chromosomal evolution.

“…Harms & Mildbraed that occurs in West Africa (Smith and Till 1998).

-(Anatomy of the floral scape of Bromeliaceae). This paper describes the anatomy of the floral scape for 12 species of Bromeliaceae, belonging to the subfamilies Bromelioideae, Tillandsioideae and Pitcairnioideae. Although all the scapes have a similar organization, there are variations in the structure of the epidermis, cortex and vascular cylinder. Such variations are described for the studied scapes and, when considered together they can help to identify the species. These aspects are described for each scape and discussed under a taxonomic point of view.Key words -anatomy, Bromeliaceae, floral scape RESUMO -(Anatomia do escapo floral de Bromeliaceae). Este trabalho descreve a anatomia do escapo floral de doze espécies de Bromeliaceae pertencentes às subfamílias Bromelioideae, Tillandsioideae e Pitcairnioideae e tem como objetivo ampliar o conhecimento anatômico da família e desse órgão em particular. Embora todos os escapos apresentem uma organização similar, observam-se variações na estrutura da epiderme, do córtex e do cilindro vascular. Tais variações são descritas para os escapos estudados e, quando são analisadas em conjunto, podem auxiliar na identificação das espécies. Esses aspectos são descritos para cada um dos escapos e discutidos dentro de um contexto taxonômico.Palavras-chave -anatomia, Bromeliaceae, escapo floral 1.Part of PhD thesis developed at Universidade Estadual Paulista Rio

“…The family Xyridaceae belongs in the order Poales and is probably most closely related to Eriocaulaceae (e.g. Davis et al 2004;Givnish et al 2010;Barrett et al 2015). Xyridaceae flowers are hermaphrodite, but Eriocaulaceae flowers are generally unisexual by late abortion of the stamens or carpels, resulting in female or male flowers, respectively (Stützel 1998).…”

Floral ontogeny and vasculature in Xyridaceae, with particular reference to staminodes and stylar appendages

et al. 2017

We provide a detailed comparative study of floral ontogeny and vasculature in Xyridaceae, including Xyris, Abolboda and Orectanthe. We evaluate these data in the context of a recent well-resolved phylogenetic analysis of Poales to compare floral structures within the xyrid clade (Xyridaceae and Eriocaulaceae). Xyrids are relatively diverse in both flower structure and anatomy; many species incorporate diverse and unusual floral structures such as staminodes and stylar appendages. Xyridaceae possess three generally epipetalous stamens in a single whorl; the ''missing'' stamen whorl is either entirely absent or transformed into staminodes. Fertile stamens each receive a single vascular bundle diverged from the median petal bundle. In Xyris, the stamen bundle diverges at the flower base, but it diverges at upper flower levels in both Abolboda and Orectanthe. In species of Abolboda that possess staminodes, staminode vasculature is closely associated with the lateral vasculature of each petal. Despite the likely sister-group relationship between Eriocaulaceae and Xyridaceae, our character optimization indicates that the stylar appendages that characterize some Xyridaceae (except Xyris and Achlyphila) are non-homologous with those of some Eriocaulaceae. On the other hand, it remains equivocal whether the loss of a fertile outer androecial whorl occurred more than once during the evolutionary history of the xyrid clade; this transition occurred either once followed by a reversal to fertile stamens in Eriocauloideae and staminodes in some Xyridaceae, or twice independently within both Xyridaceae and Eriocaulaceae.
