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 ...

INDEPENDENT ORIGINATION OF FLORAL ZYGOMORPHY, A PREDICTED ADAPTIVE RESPONSE TO POLLINATORS: DEVELOPMENTAL AND GENETIC MECHANISMS [PDF]

open access: yes, 2016
Observations of floral development indicate that floral organ initiation in pentapetalous flowers more commonly results in a medially positioned abaxial petal (MAB) than in a medially positioned adaxial petal (MAD), where the medial plane is defined by ...

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

The legacy of terrestrial plant evolution on cell wall fine structure

open access: yesPlant, Cell &Environment, Volume 47, Issue 4, Page 1238-1254, April 2024.
Abstract The evolution of land flora was an epochal event in the history of planet Earth. The success of plants, and especially flowering plants, in colonizing all but the most hostile environments required multiple mechanisms of adaptation. The mainly polysaccharide‐based cell walls of flowering plants, which are indispensable for water transport and ...

Distribution of sex forms in the phanerogamic flora [PDF]

open access: yes, 2007
In the plant kingdom, particularly in the phanerogamic flora, hermaphroditism is by far the most common, yet the number of other sex forms is not negligible.

Parasitic plants have increased rates of molecular evolution across all three genomes

open access: yes, 2015
BACKGROUND Theoretical models and experimental evidence suggest that rates of molecular evolution could be raised in parasitic organisms compared to non-parasitic taxa. Parasitic plants provide an ideal test for these predictions, as there are at least a

RNA-Seq analysis identifies key genes associated with haustorial development in the root hemiparasite Santalum album [PDF]

open access: yes, 2015
Santalum album (sandalwood) is one of the economically important plant species in the Santalaceae for its production of highly valued perfume oils. Sandalwood is also a hemiparasitic tree that obtains some of its water and simple nutrients by tapping ...

Four new neotropical Trioza species associated with Loranthaceae (Santalales) and comments on mistletoe inhabiting psyllids (Hemiptera, Psylloidea) [PDF]

open access: yesAlpine Entomology, 2017
Four new Trioza species associated with mistletoes are described, diagnosed and illustrated from Brazil and Chile. They are monophagous on the Loranthaceae Struthanthus uraguensis (Trioza struthanthi sp.

Nuclear phylogenomics of angiosperms and insights into their relationships and evolution

open access: yesJournal of Integrative Plant Biology, Volume 66, Issue 3, Page 546-578, March 2024.
This review synthesizes numerous nuclear phylogenomic analyses of angiosperms (analyses that resolved the relationships of major clades, most orders, and many families and subgroups) and discusses the improved understanding of angiosperm biogeography, diversification dynamics, and character evolution.
