Reproductive biology of the holoparasitic endophyteBdallophyton bambusarum(Rafflesiaceae) [PDF]
Botanical Journal of the Linnean Society, 1997 Abstract The reproductive biology of most species of Rafflesiaceae is unknown. We studied several aspects of that of Bdallophyton bambusarum Liebm. (Rafflesiaceae) in a subdeciduous tropical forest. Flowering of B. bambusarum is during the driest time of the year.

How do holoparasitic plants exploit vitamin K1? [PDF]
Plant Signal Behav, 2021 Phylloquinone (vitamin K1) is a thylakoid-embedded electron carrier essential for photosynthesis. Paradoxically, we found that phylloquinone biosynthesis is retained in the nonphotosynthetic holoparasite Phelipanche aegyptiaca (Egyptian broomrape). The phylloquinone pathway genes are preferentially expressed during development of the invasive organ ...

Extensive plastome reduction and loss of photosynthesis genes in Diphelypaea coccinea, a holoparasitic plant of the family Orobanchaceae [PDF]
PeerJ, 2019 Background Parasitic plants have the ability to obtain nutrients from their hosts and are less dependent on their own photosynthesis or completely lose this capacity. The reduction in plastid genome size and gene content in parasitic plants predominantly

, 2021 Nonphotosynthetic holoparasites exploit flexible targeting of phylloquinone biosynthesis to facilitate plasma membrane redox signaling. Phylloquinone is a lipophilic naphthoquinone found predominantly in chloroplasts and best known for its function in ...

Beyond parasitic convergence: unraveling the evolution of the organellar genomes in holoparasites
, 2023 The molecular evolution of organellar genomes in angiosperms has been extensively studied, with some lineages, such as parasitic ones, displaying unique characteristics.

Convergent Plastome Evolution and Gene Loss in Holoparasitic Lennoaceae
Genome Biology and Evolution, 2018 The Lennoaceae, a small monophyletic plant family of root parasites endemic to the Americas, are one of the last remaining independently evolved lineages of parasitic angiosperms lacking a published plastome. In this study, we present the assembled and annotated plastomes of two species spanning the crown node of Lennoaceae, Lennoa madreporoides and ...

Reading between the vines: Hosts as islands for extreme holoparasitic plants [PDF]
American Journal of Botany, 2017 PREMISE OF THE STUDY:Partitioning of population genetic variation in plants may be affected by numerous factors including life history and dispersal characteristics. In parasitic plants, interactions with host populations may be an additional factor influencing partitioning.

BMC Plant Biology, 2022 Background Orobanchaceae is the only flowering plant family with species from free-living nonparasite, hemi-parasite to holoparasite, making it an ideal system for studying the evolution of parasitism.

The evolution of the plastid genomes in the holoparasitic Balanophoraceae
Proceedings of the Royal Society B: Biological SciencesThe independent transition to a heterotrophic lifestyle in plants drove remarkably convergent evolutionary trajectories, characterized by morphological modifications and reductions in their plastomes. The characteristics of the minimum plastome required for survival, if they exist, remain a topic of debate. The holoparasitic family
