FIRST HOST RECORD FOR THE ROOT PARASITE CORYNAEA CRASSA (BALANOPHORACEAE)
Acta Biológica Colombiana, 2009 Corynaea crassa es una planta hemiparásita de raiz poco común y de la cual sabemos muy poco acerca de su historia natural y en particular sobre su rango de hospederos. En este estudio escabamos 32 tuberculos de dicha especie y seguimos las raíces que estaban parasitando para determinar su identidad.

Spring Forward: Reproductive Phenology of the Holoparasite <i>Lathraea squamaria</i> (Orobanchaceae). [PDF]
Plant Environ InteractLathraea squamaria is a peculiar holoparasitic plant. Here, we show that over a 14‐year period, key stages in the reproductive phenology of this parasite have started significantly earlier. Most remarkably, initial dates of flower anthesis and seed release now occur five and nine days earlier, respectively, when compared to 2007. ABSTRACT Lathraea is a

Altered Mitochondrial Respiration Is Associated With Loss of Nuclear-Encoded OXPHOS Genes in Parasitic Broomrapes. [PDF]
Ecol EvolThe holoparasitic tribe Orobancheae demonstrated significant gene losses in their nuclear‐encoded mitochondrial OXPHOS genes. Despite these losses, high resolution respirometry revealed robust mitochondrial respiration in Orobancheae by shifting activities to fully nuclear encoded alternative complexes. ABSTRACT Parasitic plants, characterized by their

Cytotoxic Activity of Opopanax hispidus (Friv.) Griseb.: Characterization of a New Chalcone-type Compound. [PDF]
Chem BiodiversABSTRACT The present study aimed to investigate cytotoxic compounds of Opopanax hispidus (Friv.) Griseb. through in vitro, in silico, and phytochemical analyses. The cytotoxic activity of O. hispidus was evaluated against four different cancer cell lines – lung (A549), breast (MCF‐7), liver (HepG2), and cervix (HeLa) – as well as one healthy cell line (

Journal of Mathematical and Fundamental Sciences, 2021 Balanophora elongata (Balanophoraceae) is a tropical parasitic flowering plant 9 cm in height. Four known phenyl acrylic acid derivatives, methyl caffeate (1), caffeic acid (2), 1,6-di-O-caffeoyl-β-D-glucopyranose (3), and coniferin (4), were isolated ...

Austral Ecology, Volume 48, Issue 8, Page 1762-1778, December 2023., 2023 Flowers of the Tasmanian endemic shrub Richea dracophylla are covered with a calyptra which is removed by birds before insect pollination can occur. Nocturnal ants Notoncus hickmani were active on flowers in large numbers at temperatures down to 2.5°C. Abstract Our observation of large numbers of ants Notoncus hickmani (Formicinae) on the flowers of a ...

Plastid phylogenomics and molecular evolution of Thismiaceae (Dioscoreales)
American Journal of Botany, Volume 110, Issue 4, April 2023., 2023 Abstract Premise Species in Thismiaceae can no longer photosynthesize and instead obtain carbon from soil fungi. Here we infer Thismiaceae phylogeny using plastid genome data and characterize the molecular evolution of this genome. Methods We assembled five Thismiaceae plastid genomes from genome skimming data, adding to previously published data for ...

Neglected plant parasites: Mitrastemonaceae
PLANTS, PEOPLE, PLANET, Volume 5, Issue 1, Page 5-13, January 2023., 2023 Mitrastemonaceae are a remarkable family of parasitic flowering plants. The two species that make up this family have a disjunct distribution and a peculiar appearance. Both are devoid of roots, stems, and regular leaves and live inside the roots of their host plants for most of their life cycle.
