Phylogenetic Relationships in the Aveneae/Poeae Complex (Pooideae, Poaceae)
TLDR
The results support a broadly delineated subfamily Pooideae with Brachyelytrum and Nardus/Lygeutm as basal lineages and Aveneae/Poeae + Bromeae/Triticeae + Brachypodium as sister to a well-supported lineage.
Phylogenetic structure of the grass subfamily Pooideae based on comparison of plastid matK gene-3'trnK exon and nuclear ITS sequences
TLDR
The results do not reveal a significant role of past hybridisation, plastid lineage sorting or reticulation in the evolutionary diversification of the major lineages of the grass subfamily Pooideae and a largely well-supported pattern of divergence is results in.
Nuclear DNA Amounts in Palms (Arecaceae)
TLDR
Nuclear DNA amounts are reported for 83 species and 53 genera of palms, covering all of the six subfamilies, and considerable variation occurs at the diploid level in some large and apparently actively evolving genera such as Chamaedorea, Pinanga, Cenoma and possibly Bactris.
In and out of the Qinghai‐Tibet Plateau: divergence time estimation and historical biogeography of the large arctic‐alpine genus Saxifraga L.
TLDR
The biogeographical history of the large genus Saxifraga is studied to unravel the role played by the Qinghai‐Tibet Plateau for the diversification of this genus and to understand factors that have led to the establishment of high biodiversity in and around this region.
Molecular diversity and physical mapping of 5S rDNA in wild and cultivated oat grasses (Poaceae: Aveneae).
TLDR
The "uncommon" 5S gene sequences detected in some Aveneae are not necessarily nonfunctional as pseudogenes because the essential features of the internal control region are maintained even after such duplication events.
PARALLEL EVOLUTIONARY PATTERNS IN MULTIPLE LINEAGES OF ARCTIC ARTEMISIA L. (ASTERACEAE)
TLDR
Artemisia has independently adapted to Arctic habitats 13–18 times and enlarged flower heads have evolved repeatedly, probably for better pollinator attraction, which could be a substitute for polyploidy, which is typical in other Arctic taxa.
Duthieeae, a new tribe of grasses (Poaceae) identified among the early diverging lineages of subfamily Pooideae: molecular phylogenetics, morphological delineation, cytogenetics and biogeography
TLDR
Morphological, cytogenetic and biogeographical analyses point to warm and humid conditions as the ancestral bioclimatic niche of Phaenosperma and Duthieeae, whereas adaptation to cold and drought occurred only in a part of DuthIEeae but was obviously less successful than in the widespread and much more species-rich tribe Stipeae.
Molecular phylogenetic relationships inAveneae (Poaceae) species and other grasses as inferred from ITS1 and ITS2 rDNA sequences
TLDR
A phylogenetic analysis was conducted on sequences of the internal transcribed spacer (ITS) region of nuclear ribosomal DNA in 23 species of Aveneae and suggests unexpectedly close affinities of the agronomically important genusAvena to comparatively small-flowered taxa ofAveneae.
Pathways of karyological differentiation in palms (Arecaceae)

    Plant Systematics and Evolution
  • 1 March 1994
TLDR
Karyological characters are compared to morphological, ecological, taxonomical, and chorological features, and give some new insight into older and more recent phases of palm evolution.
