Continental‐scale interactions of Australian showy mistletoes and their hosts

open access: yesAmerican Journal of Botany, Volume 111, Issue 12, December 2024.
Abstract Premise Showy mistletoes are obligate hemiparasites of woody plants. Host specificity is therefore a fundamental determinant of mistletoe diversity, persistence, geographic distribution, and abundance. Investigations of host specificity in Australian Loranthaceae have focused mostly on host range (taxon counts), but additional insights into ...

Single-copy nuclear genes place haustorial Hydnoraceae within piperales and reveal a cretaceous origin of multiple parasitic angiosperm lineages. [PDF]

open access: yesPLoS ONE, 2013
Extreme haustorial parasites have long captured the interest of naturalists and scientists with their greatly reduced and highly specialized morphology. Along with the reduction or loss of photosynthesis, the plastid genome often decays as photosynthetic

Repeated shifts out of tropical climates preceded by whole genome duplication

open access: yesNew Phytologist, Volume 244, Issue 6, Page 2561-2575, December 2024.
Summary While flowering plants have diversified in virtually every terrestrial clime, climate constrains the distribution of individual lineages. Overcoming climatic constraints may be associated with diverse evolutionary phenomena including whole genome duplication (WGD), gene‐tree conflict, and life‐history changes.

Complete chloroplast genomes of the hemiparasitic genus Cymbaria: Insights into comparative analysis, development of molecular markers, and phylogenetic relationships

open access: yesEcology and Evolution, Volume 14, Issue 7, July 2024.
Specific DNA barcodes were developed and validated from the Cymbaria chloroplast genomes to distinguish the traditional Mongolian medicine Cymbaria daurica from its adulterant Cymbaria mongolica. Abstract The hemiparasitic tribe Cymbarieae (Orobanchaceae) plays a crucial role in elucidating the initial stage of the transition from autotrophism to ...
