Both hummingbirds and bats pollinate the species-rich and morphologically diverse genus Vriesea across its distribution in the Brazilian Atlantic Forest. Here, we (i) determine if floral traits predict functional groups of pollinators as documented, confirming the pollination syndromes in Vriesea and (ii) test if genetic structure in Vriesea is driven by geography (latitudinal and altitudinal heterogeneity) or ecology (pollination syndromes). -

To remedy this, we sequenced small RNAs from vegetative and dissected 5 inflorescence tissue in 28 phylogenetically diverse monocots and from several early‐diverging 6 angiosperm lineages, as well as publicly available data from 10 additional monocot species. -

Water Relations of Bromeliaceae in Their Evolutionary Context
View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by Apollo Botanical Journal of the Linnean Society, 2016, 181, 415–440. With 2 figures Think tank: water relations of Bromeliaceae in their evolutionary context JAMIE MALES* Department of Plant Sciences, University of Cambridge, Downing Street, Cambridge CB2 3EA, UK Received 31 July 2015; revised 28 February 2016; accepted for publication 1 March 2016 Water relations represent a pivotal nexus in plant biology due to the multiplicity of functions affected by water status. Hydraulic properties of plant parts are therefore likely to be relevant to evolutionary trends in many taxa. Bromeliaceae encompass a wealth of morphological, physiological and ecological variations and the geographical and bioclimatic range of the family is also extensive. The diversification of bromeliad lineages is known to be correlated with the origins of a suite of key innovations, many of which relate directly or indirectly to water relations. However, little information is known regarding the role of change in morphoanatomical and hydraulic traits in the evolutionary origins of the classical ecophysiological functional types in Bromeliaceae or how this role relates to the diversification of specific lineages. In this paper, I present a synthesis of the current knowledge on bromeliad water relations and a qualitative model of the evolution of relevant traits in the context of the functional types. I use this model to introduce a manifesto for a new research programme on the integrative biology and evolution of bromeliad water-use strategies. The need for a wide-ranging survey of morphoanatomical and hydraulic traits across Bromeliaceae is stressed, as this would provide extensive insight into structure– function relationships of relevance to the evolutionary history of bromeliads and, more generally, to the evolutionary physiology of flowering plants. -

Brennan Citation: Neri J, Wendt T, Palma-Silva C. 2018. Natural hybridization and genetic and morphological variation between two epiphytic bromeliads. AoB PLANTS 10: plx061; doi: 10.1093/aobpla/plx061 Abstract. Reproductive isolation is of fundamental importance for maintaining species boundaries in sympatry. Here, we examine the genetic and morphological differences between two closely related bromeliad species: Vriesea simplex and Vriesea scalaris. Furthermore, we examined the occurrence of natural hybridization and discuss the action of reproductive isolation barriers. Nuclear genomic admixture suggests hybridization in sympatric popula- tions, although interspecific gene flow is low among species in all sympatric zones (Nem < 0.5). Thus, morphological and genetic divergence (10.99 %) between species can be maintained despite ongoing natural hybridization. Cross- evaluation of our genetic and morphological data suggests that species integrity is maintained by the simultaneous action of multiple barriers, such as divergent reproductive systems among species, differences in floral traits and low hybrid seed viability. -

Huanca-Mamani) Received: 3 June 2019; accepted: 17 February 2020 Abstract Tillandsia landbeckii Phil. is a typical plant of the Atacama Desert in the north of Chile. There is no genetic data available at the population level for this species, and this information is critical for developing and implementing effective conservation measures. In this study, we investigated for the first time the genetic diversity and population structure in 2 natural populations of T. landbeckii using AFLP markers. Seven primer combinations produced 405 bands and of them, 188 (46.42%) were polymorphic. The Pampa Dos Cruces population (Pp = 88.30%, He = 0.327, and I = 0.483) showed a higher genetic diversity level than Pampa Camarones population (Pp = 71.28%, He = 0.253, and I = 0.380). -

Nuclear Genes, Matk and the Phylogeny of the Poales
Zurich Open Repository and Archive University of Zurich Main Library Strickhofstrasse 39 CH-8057 Zurich www.zora.uzh.ch Year: 2018 Nuclear genes, matK and the phylogeny of the Poales Hochbach, Anne ; Linder, H Peter ; Röser, Martin Abstract: Phylogenetic relationships within the monocot order Poales have been well studied, but sev- eral unrelated questions remain. These include the relationships among the basal families in the order, family delimitations within the restiid clade, and the search for nuclear single-copy gene loci to test the relationships based on chloroplast loci. To this end two nuclear loci (PhyB, Topo6) were explored both at the ordinal level, and within the Bromeliaceae and the restiid clade. First, a plastid reference tree was inferred based on matK, using 140 taxa covering all APG IV families of Poales, and analyzed using parsimony, maximum likelihood and Bayesian methods. The trees inferred from matK closely approach the published phylogeny based on whole-plastome sequencing. Of the two nuclear loci, Topo6 supported a congruent, but much less resolved phylogeny. By contrast, PhyB indicated different phylo- genetic relationships, with, inter alia, Mayacaceae and Typhaceae sister to Poaceae, and Flagellariaceae in a basally branching position within the Poales. Within the restiid clade the differences between the three markers appear less serious. The Anarthria clade is first diverging in all analyses, followed by Restionoideae, Sporadanthoideae, Centrolepidoideae and Leptocarpoideae in the matK and Topo6 data, but in the PhyB data Centrolepidoideae diverges next, followed by a paraphyletic Restionoideae with a clade consisting of the monophyletic Sporadanthoideae and Leptocarpoideae nested within them. The Bromeliaceae phylogeny obtained from Topo6 is insufficiently sampled to make reliable statements, but indicates a good starting point for further investigations. -

Plant-Hummingbird Interactions: Natural History and Ecological Networks
Pietro Kiyoshi Maruyama Mendonça Plant-hummingbird interactions: natural history and ecological networks Interações entre plantas e beija-flores: história natural e redes ecológicas CAMPINAS 2015 Aos meus pais, Dario e Isumi e a Amandinha Agradecimentos Uma tese de doutorado é o resultado de um longo caminho, e inevitavelmente é preciso contar com a ajuda de muitas pessoas para ser finalizada. Tudo começou com os meus pais, Dario e Isumi, que resolveram "juntar as coisas" a quase trinta anos atrás. E a quase trinta anos eles têm feito de tudo para me dar todo o apoio possível. Agradeço muito a sorte de ter tido pais tão dedicados e amorosos. Obrigado! Essa tese não seria possível sem o apoio e orientação da Profa. Marlies. Agradeço o fato de ela ter me aberto as portas do seu laboratório e de certa maneira também da Unicamp. A professora é sempre um grande exemplo (que todos gostariam de ser) de como lidar com a vida acadêmica, para que esta continue divertida para você, mas também para os outros ao seu redor. Espero ter pego alguma coisa da sua sabedoria! Chegando aqui, ainda vejo que a minha formação se deve muito ao meu primeiro orientador, o Paulo. Em muitos aspectos parecido com a Profa. Marlies, mas em tantos outros bem diferente, é também um exemplo que tenho para mim. O que me deixa muito feliz é que as portas da sua sala continuam sempre abertas. Essa tese também me ofereceu a oportunidade de aprender com um co-orientador "gringo". Agradeço muito ao Bo, pelo crescimento profissional tão importante que me proporcionou.
