Do tropical plants have smaller genomes? Correlation between genome size and climatic variables in the Caesalpinia Group (Caesalpinioideae, Leguminosae)
While a number of studies have suggested that temperate plants typically have larger genome sizes (GS) than tropical ones, recent analyses have not convincingly confirmed this. We have selected the widely distributed Caesalpinia Group (Leguminosae) to test this hypothesis. We used flow cytometry to estimate the amount of DNA in...Souza, Gustavo ; Costa, Lucas ; Guignard, Maïté ; Van-Lume, Brena ; Pellicer, Jaume …

Diversity and conservation priorities of crop wild relatives in Mexico
Crop wild relatives (CWR) are valuable resources for crop breeding due to their close genetic relationship to the cultivated plants and their wide genetic variation, allowing the introgression of desirable traits into the crops, such as resistance to plant pests and diseases or adaptability to climate change. Mexico is a...Contreras-Toledo, Aremi ; Cortés-Cruz, Moisés ; Costich, Denise ; Rico-Arce, María de Lourdes ; Magos Brehm, Joana …

Cryptic species in an ancient flowering-plant lineage (Hydatellaceae, Nymphaeales) revealed by molecular and micromorphological data
The flora of the southwestern Australian biodiversity hotspot is rich in endemic species, many of which remain to be discovered or properly described; estimates of species diversity and levels of endemism should take into account the possible occurrence of cryptic species. Here we explore taxonomic diversity in a Western Australian...Sokoloff, Dmitry ; Marques, Isabel ; Macfarlane, Terry ; Remizowa, Margarita ; Lam, Vivienne …

Digest: Linking coordinated shifts in plant resource allocation to a chromosomal inversion
Local adaptation in plants often requires coordinated shifts among resources. Lowry et al. provide evidence for physiological and genomic mechanisms underpinning adaptive shifts in yellow monkeyflower (Mimulus guttatus), such as the transition between annual and perennial life histories. In M. guttatus, differential activity of gibberellins, governed partially by a chromosomal inversion,...Dodsworth, S ; Pérez-Escobar, O

Convergent origin of the narrowly lanceolate leaf in the genus Aster-with special reference to an unexpected discovery of a new Aster species from East China
Narrowly lanceolate leaves occur frequently in the genus Aster. It was often employed as a distinguishing character in the taxonomy of this genus. The origin of this particular leaf shape, however, has never been investigated using comparative methods. In this study, we reconstructed a comprehensive phylogeny that includes most species...Zhang, G ; Hu, H ; Gao, T ; Gilbert, M ; Jin, X

Crosslandia setifolia is a partly monoecious species of Fimbristylis (Abildgaardieae: Cyperaceae)
While the limits of Fimbristylis Vahl (1805: 285) are contentious (Goetghebeur & Coudijzer 1984, Gordon-Gray 1971, Lye 1971, 1973), particularly with regard to the inclusion of Abildgaardia Vahl (1805: 296) within Fimbristylis , all current data support the derivation of Crosslandia W.Fitzg. (1906: 9) from within Fimbristylis (Ghamkhar et al....Roalson, Eric ; Barrett, Russell ; Wilson, Karen ; Bruhl, Jeremy ; Larridon, Isabel

Contributions to the knowledge of Cambodian Cyperaceae
To date, there are very few sequence data for Cyperaceae from mainland Southeast Asia. The aim of the present study was to contribute nuclear ribosomal internal transcribed spacer (ITS) sequences of selected species of Cambodian Cyperaceae to the overall phylogeny of the family. We generated ITS sequences of 38 accessions...Tremetsberger, K ; Hameister, S ; Simpson, D ; Bernhardt, K

Coenocytic growth phases in land plant development: a paleo-evo-devo perspective
Premise of research.?The evolutionary origin of the seed habit coincided with profound physiological and structural changes associated with underlying developmental patterns. A coenocyte is formed during megagametophyte development in many vascular plants, including some lycophytes and all spermatophytes; this structure compares closely with similar free-nuclear growth phases during embryo development...Rudall, Paula ; Bateman, Richard

Compendium of Freziera (Pentaphylacaceae) of South America including eleven new species and the typification of 22 names
As part of a revision of neotropical Freziera (Pentaphylacaceae) we provide a compendium of the 63 species we recognise for South America including the description, illustration and extinction threat assessment of 11 new species, typification of 22 names and a new combination for Freziera rufescens (Kobuski) D.

Checklist to the Elatostema (Urticaceae) of Vietnam including 19 new records, ten new combinations, two new names and four new synonyms
Elatostema (Urticaceae) comprises several hundred herbaceous species distributed in tropical and subtropical Africa, Asia, Australia and Oceania. The greatest species richness occurs on limestone karst in Southeast Asia. Taxonomic revisions of Elatostema are largely out of date and contradict each other with respect to the delimitation of Elatostema and Pellionia....Fu, Long-Fei ; Monro, Alex ; Do, Truong ; Nuraliev, Maxim ; Averyanov, Leonid …
