Symbiont-mediated protection [PDF]

Proceedings of the Royal Society B: Biological Sciences, 2007
Despite the fact that all vertically transmitted symbionts sequester resources from their hosts and are therefore costly to maintain, there is an extraordinary diversity of them in invertebrates. Some spread through host populations by providing their hosts with fitness benefits or by manipulating host sex ratio, but some do not: their maintenance in ...

Pollination by long‐proboscid horseflies and its implications for reproductive isolation among coflowering Satyrium orchids in South Africa

American Journal of Botany, EarlyView.
Abstract Premise Floral adaptations to pollinators can drive lineage diversification and promote coexistence of species. We investigated the reproductive biology of Satyrium longicolle, a South African orchid that we hypothesized to belong to a long‐proboscid horsefly pollination guild and examined overlap of pollinators and floral traits among ...

Off‐target metagenomics: Leveraging whole genome sequencing to study the bacteriome of the liverwort Calasterella californica

Applications in Plant Sciences, EarlyView.
Abstract Premise The recovery of non‐target organism reads, especially when whole organisms are sampled, constitutes a great opportunity for studying microbial communities. The increase in whole genome sequencing feasibility and the development of new marker‐based pipelines enable the use of short reads to study bacterial communities associated with ...

Identification and analysis of the secretome of plant pathogenic fungi reveals lifestyle adaptation

Frontiers in Microbiology, 2023
The secretory proteome plays an important role in the pathogenesis of phytopathogenic fungi. However, the relationship between the large-scale secretome of phytopathogenic fungi and their lifestyle is not fully understood.

A roadmap to key traits of invasive Drosophilidae

Biological Reviews, EarlyView.
ABSTRACT Biological invasions have intensified in recent decades, mostly driven by international trade and travel, raising significant concerns, particularly regarding insect pests. Once non‐native species establish, they can disrupt natural ecosystem stability, undermine agroecosystem sustainability and cause substantial economic losses.

The ageing holobiont: crosstalk between telomere dynamics, oxidative stress and the gut microbiome

Biological Reviews, EarlyView.
ABSTRACT The gut tissue is at the frontline of early onset of ageing. It exhibits high cell turnover rates and rapid telomere shortening, which can have systemic effects on the developing or senescing organism. We conducted a literature review of studies on the crosstalk between telomere length dynamics, telomerase activity, oxidative stress, and gut ...

Ecology and evolution of pyrazines in insects

Biological Reviews, EarlyView.
ABSTRACT Chemical communication is the oldest and most widespread form of signalling among and within organisms. Among the many compounds involved in such communication, pyrazines – nitrogen‐containing heterocyclic molecules – are especially intriguing due to their widespread occurrence across the tree of life, from bacteria and fungi to insects and ...

RORγt‐APCs: The New Masters of Oral Tolerance

Barrier Immunity, EarlyView.
ABSTRACT Oral tolerance is defined by the hypo‐responsiveness of our body to fed antigens, and its failure can lead to immune‐mediated diseases, such as allergy, chronic inflammation and autoimmune diseases. Decades of research have demonstrated that antigen‐presenting cells (APCs) promote oral tolerance by inducing regulatory T cells (Tregs) and/or ...

Enemy release: loss of parasites in invasive freshwater bivalves Sinanodonta woodiana and Corbicula fluminea

Ecography, EarlyView.
Invasive freshwater bivalves harm native species, ecosystems and biodiversity, and incur economic costs. The enemy release hypothesis posits that invasive species are released from enemies during the invasion process, giving them a competitive advantage in the new environment.
