Diversification of CYCLOIDEA-like genes in Dipsacaceae (Dipsacales): implications for the evolution of capitulum inflorescences [PDF]

open access: yesBMC Evolutionary Biology, 2011
Background CYCLOIDEA (CYC)-like genes have been implicated in the development of capitulum inflorescences (i.e. flowering heads) in Asteraceae, where many small flowers (florets) are packed tightly into an inflorescence that resembles a single flower ...

Reconstructing Dipsacales phylogeny using Angiosperms353: issues and insights. [PDF]

open access: yesAm J Bot, 2021
PremisePhylogenetic relationships within major angiosperm clades are increasingly well resolved, but largely informed by plastid data. Areas of poor resolution persist within the Dipsacales, including placement of Heptacodium and Zabelia, and relationships within the Caprifolieae and Linnaeeae, hindering our interpretation of morphological evolution ...

Evolution of fruit and seed characters in the Diervilla and Lonicera clades (Caprifoliaceae, Dipsacales) [PDF]

open access: yesAnnals of Botany, 2009
The Diervilla and Lonicera clades are members of the family Caprifoliaceae (Dipsacales sensu Donoghue et al., 2001, Harvard Papers in Botany 6: 459-479).

The Role of Plant Evolutionary History in Shaping the Variation in Specific Leaf Area Across China. [PDF]

open access: yesEcol Evol
In this study, we analyzed the influences of climatic conditions and soil properties on the specific leaf area (SLA), calculated the phylogenetic signals of SLA, and quantified the relative contributions of evolutionary history to the spatial variation in SLA. We underscored the importance of evolutionary history in shaping the spatial variation of SLA

Herbivory Dominates the Spring Diet of American Black Bears (<i>Ursus americanus</i>) in a Wood Bison (<i>Bison bison athabascae</i>) Neonatal Range, Suggesting Minimal Bison Consumption. [PDF]

open access: yesEcol Evol
In this study, we used scat analysis and DNA metabarcoding to analyze the spring diet of black bears in the neonatal range of a small, threatened wood bison herd in northeast Alberta to assess predation risk of neonate bison. Our results suggest that consumption rates of bison are low and that predation risk to neonate wood bison, during the RLBH's ...

Climate adaptation and functional constraints drive pollen evolution in Apiales. [PDF]

open access: yesNew Phytol
Summary Pollen grains exhibit remarkable morphological diversity, shaped by selective pressures from environmental factors and mechanical constraints. Here, we investigate macroevolutionary patterns of pollen morphology in Apiales, an order of angiosperms with significant ecological and geographical diversity, to disentangle the roles of climate and ...

Complete Chloroplast Genome Sequence of Triosteum sinuatum, Insights into Comparative Chloroplast Genomics, Divergence Time Estimation and Phylogenetic Relationships among Dipsacales. [PDF]

open access: yesGenes (Basel), 2022
Triosteum himalayanum, Triosteum pinnatifidum (Triosteum L., Caprifoliaceae, Dipsacales) are widely distributed in China while Triosteum sinuatum mainly occurrs in northeast China. Few reports have been determined on the genus Triosteum. In the present research, we sequenced 2 chloroplast genomes of Triosteum and analyzed 18 chloroplast genomes, trying

Phenolic compounds in species of the Blechnaceae. [PDF]

open access: yesPlant Biol (Stuttg)
The occurrence of caffeic acid derivatives in 32 species of Blechnaceae revealed differences in the presence of rosmarinic acid and blechnic acid B, a novel compound in ferns. Abstract Rosmarinic acid and other caffeic and 4‐coumaric acid derivatives are widespread in land plants.

Phylogeny and biogeography of Morinaceae (Dipsacales) based on nuclear and chloroplast DNA sequences [PDF]

open access: yesInternational Journal of Plant Sciences, 2003
Improved knowledge of Dipsacales phylogeny provides a solid framework for studies of character evolution. Although the polarity of many characters can now be confidently established, for others it remains unclear. This results largely from uncertainty about the broader relationships of Dipsacales and is especially problematic for characters that ...

Progestogens and androgens influence root morphology of angiosperms in a brassinosteroid-independent manner. [PDF]

open access: yesPlant J
Significance Statement Plants produce progesterone and androgens, which alter root morphology in A. thaliana and 60% of tested angiosperms. Brassinosteroids seem uninvolved. Understanding the mechanism is like navigating an unknown city—exemplarily Dittelbrunn (a small village in Bavaria)—where the expected shortcut (interaction with brassinosteroids ...
