Plastid phylogenomic insights into the evolution of Caryophyllales
The Caryophyllales includes 40 families and 12,500 species, representing a large and diverse clade of angiosperms. Collectively, members of the clade grow on all continents and in all terrestrial biomes and often occupy extreme habitats (e.g., xeric, salty). The order is characterized by many taxa with unusual adaptations including carnivory,...Yao, Gang ; Jin, Jian-Jun ; Li, Hong-Tao ; Yang, Jun-Bo ; Mandala, Venkata …

Phytolith-based environmental reconstruction from an altitudinal gradient in Mpumalanga, South Africa, 10,600 BP–present
Studying vegetation change across biome boundaries provides insight into vegetation resilience. In this study, shifts in grassland composition are reconstructed from sediments in three wetland sites across altitudinal gradient from 2128 to 897 m.a.s.l., representing a gradient from the grassland biome to the grassland/savanna boundary in the Mpumalanga region, north-eastern South...Breman, Elinor ; Ekblom, Anneli ; Gillson, Lindsey ; Norström, Elin

Plant genome sequences: past, present, future
The green plants (Viridiplantae) are an essential kingdom of life, responsible via photosynthesis for the majority of global primary production, and directly utilized by humankind for nutrition, animal feed, fuel, clothing, medicine and other purposes. There are an estimated 391 000 species of land plants, in addition to 8000 species of...Kersey, P

Plastome phylogenomics of sugarcane and relatives confirms the segregation of the genus Tripidium (Poaceae: Andropogoneae)
Sugarcane (Saccharum officinarum) is one of the most important crops in the world and a major source of sugar for human consumption. Despite this immense value, the circumscription of the genus Saccharum is complex, contentious, and largely unresolved. Saccharum is accepted in a broad sense by some authors or split...Welker, Cassiano ; McKain, Michael ; Vorontsova, Maria S. ; Peichoto, Myriam ; Kellogg, Elizabeth

Pinanga schwanerensis, a new species of pinanga (arecaceae) from Kalimantan, Indonesia
A new species of palm, Pinanga schwanerensis, is described and illustrated here. This is the third species of Pinanga to have been described from Kalimantan since the description of P. salicifolia Bblume and P. albescens Bbecc. A discussion of its morphological characters, distribution, ecology, habitat and conservation status is provided....Randi, A ; Hikmat, A ; Heatuatubunun, C

Phylogeny of two African genera of Sapotaceae - Englerophytum and Synsepalum
Englerophytum and Synsepalum are two closely related genera of trees and shrubs from the African tropics. Previous molecular studies have shown that these genera collectively form a clade within the subfamily Chrysophylloideae (Sapotaceae). However, little is known about the inter-relationships of the taxa within the Englerophytum-Synsepalum clade. In this study,...Borg, D ; Richardson, J ; Harris, D ; Gautier, L ; Hughes, M …

Phylogenomics of Orchidaceae based on plastid and mitochondrial genomes
To advance our knowledge of orchid relationships and timing of their relative divergence, we used 76 protein-coding genes from plastomes (ptCDS) and 38 protein-coding genes from mitochondrial genomes (mtCDS) of 74 orchids representing the five subfamilies and 18 tribes of Orchidaceae, to reconstruct the phylogeny and temporal evolution of the...Li, Yun-Xia ; Li, Zhang-Hai ; Schuiteman, Andre ; Chase, Mark ; Li, Jian-Wu …

Phylogeography and post-glacial dynamics in the clonal-sexual orchid Cypripedium calceolus L
Aim We investigated the phylogeographical history of a clonal-sexual orchid, to test the hypothesis that current patterns of genetic diversity and differentiation retain the traces of climatic fluctuations and of the species reproductive system. Location Europe, Siberia and Russian Far East. Taxon Cypripedium calceolus L. (Orchidaceae). Methods Samples (>900, from...Gargiulo, Roberta ; Pironon, Samuel ; Zheleznaya, Ekaterina ; Sanchez, Michele ; Balázs, Zoltan …
