Ancient hybridization and phylogenetic discordance: Exploring evolutionary complexity in Asteraceae. [PDF]

open access: yesAppl Plant Sci
Abstract Premise Conflicting phylogenetic signals are common in plant phylogenomics and often reflect evolutionary histories shaped by processes like hybridization, incomplete lineage sorting, and whole‐genome duplication (WGD). We aimed to identify and assess these complex processes in the hyper‐diverse family Asteraceae to offer insight into the ...

Genome architecture modulates 35S and 5S rDNA homogenization in Asteraceae. [PDF]

open access: yesPlant J
SUMMARY Concerted evolution is the model by which multicopy gene families are homogenized across genomes, with ribosomal DNA (rDNA) as its textbook example. However, the extent and efficiency of this process may vary depending on genomic factors. The plant family Asteraceae provides a natural comparative system to address the evolutionary dynamics of ...

Notes on the distribution of Ligularia kingiana (W. W. Sm.) Hand.-Mazz. (Asteraceae): new records

open access: yesTurczaninowia, 2022
The Himalayan species Ligularia kingiana (W. W. Sm.) Hand.-Mazz., which for a long time was considered as endemic to the state of Sikkim (India), was first found during field work in the state of Nagaland, almost 700 km from the type locality.

The Complete Chloroplast Genome of <i>Synotis solidaginea</i> and Phylogenetic Analysis. [PDF]

open access: yesEcol Evol
Species within the Asteraceae genus Synotis are difficult to accurately identify using traditional methods due to their highly similar morphology. In this study, the complete chloroplast genome of Synotis solidaginea was sequenced and comparatively analyzed.

Senecioneae (Asteraceae) of the Succulent Karoo and “geography of macroevolution of higher plants”: a chorological essay

open access: yesTurczaninowia, 2023
The geographic characteristic of plant macroevolution is manifested in general in neither even, nor random distribution of the archaic and advanced representatives of a higher taxon in its range. The explanatory concepts proposed are still contradictory.

Senecio pokohinuensis (Asteraceae), a new combination for an endemic species of Mokohinau Islands, Hauraki Gulf (Tikapa Moana o Hauraki), northern Te Ika a Maui / North Island, Aotearoa / New Zealand

open access: yesUkrainian Botanical Journal, 2022
Previous research has demonstrated that Senecio repangae subsp. repangae and subsp. pokohinuensis have independent evolutionary origins. Here, we therefore elevate subsp. pokohinuensis to species rank: Senecio pokohinuensis.

Spatial Phylogenetics Reveals Endemism Hotspots and Conservation Priorities in Chinese Asteraceae. [PDF]

open access: yesEcol Evol
Based on the phylogenetic method and the spatial distribution data of 1092 Asteraceae plants in China, this study conducted a preliminary evaluation on the biodiversity and spatial phylogeny of Asteraceae plants in China for the first time and determined the biodiversity and endemic hotspots worthy of priority protection.

Comparative plastome analysis of Blumea, with implications for genome evolution and phylogeny of Asteroideae

open access: yesEcology and Evolution, 2021
The genus Blumea (Asteroideae, Asteraceae) comprises about 100 species, including herbs, shrubs, and small trees. Previous studies have been unable to resolve taxonomic issues and the phylogeny of the genus Blumea due to the low polymorphism of molecular
