Heat‐evolved coral photosymbionts exhibit dampened stress responses across distinct physiological contexts

New Phytologist, EarlyView.
Summary Experimental evolution under elevated temperatures has generated heat‐evolved (HE) strains of Symbiodiniaceae that enhance coral bleaching tolerance. However, the biomolecular mechanisms underlying this resilience remain poorly understood. We conducted a laboratory heat‐stress experiment and applied synchrotron‐based Fourier transform infrared (

The Holobiontic Figure: Narrative Complexities of Holobiont Characters in Joan Slonczewski’s Brain Plague

Open Cultural Studies, 2023
Abstract In this article, I propose to consider the holobiontic figure as a starting point for examining how literary narratives represent the holobiosis paradigm and its impact on narrative structure. A body of recent science fiction works is challenging the long-standing narrative of microbes as “bad germs” and the ever-evolving plot ...

Specific plasmid patterns and high rates of bacterial co-occurrence within the coral holobiont [PDF]

, 2018
Despite the importance of coral microbiomes for holobiont persistence, the interactions among these arenot well understood. In particular, knowledge of the co-occurrence and taxonomic importance of specific members of the microbial core, as well as ...

Ocean warming indirectly affects seagrass performance through effects on sediment microbial communities

New Phytologist, EarlyView.
Summary Belowground microbes are increasingly recognised as mediators of plant responses to stress, but it remains unclear whether the thermal histories of marine plants and their associated belowground microbes influence plant performance under ocean warming.

Transgressive Hybrids as Hopeful Holobionts

Microbiome
Background: Hybridization between evolutionary lineages has profound impacts on the fitness and ecology of hybrid progeny. In extreme cases, the effects of hybridization can transcend ecological timescales by introducing trait novelty upon which evolution can act.

Relative Diazotroph Abundance in Symbiotic Red Sea Corals Decreases With Water Depth

Frontiers in Marine Science, 2019
Microbial dinitrogen (N2) fixation (diazotrophy) is a trait critical for coral holobiont functioning. The contribution of N2 fixation to holobiont nitrogen (N) supply likely depends on the ecological niche of the coral holobiont.

The effects of environmental conditions on quorum sensing and community interactions in coral-associated bacteria [PDF]

, 2013
The coral holobiont contains diverse communities of bacteria that play a role in the maintenance of coral ecosystems, however little is known about the structure and conservation of the host-bacterial relationship.

Symbiosis through exploitation and the merger of lineages in evolution [PDF]

, 1998
A model for the coevolution of two species in facultative symbiosis is used to investigate conditions under which species merge to form a single reproductive unit.

Pseudomonas volatiles shape the root transcriptome and microbiome to promote plant growth under drought

New Phytologist, EarlyView.
Summary Volatile organic compounds (VOCs) emitted by soil bacteria influence interactions with other soil microbes and plants. While their potential as plant growth promoters is well recognized, their role in promoting plant resilience to abiotic stress and the underlying molecular mechanisms remain poorly understood.

Geographical separation and physiology drive differentiation of microbial communities of two discrete populations of the bat Leptonycteris yerbabuenae

MicrobiologyOpen, 2020
In this paper, we explore how two discrete and geographically separated populations of the lesser long‐nosed bat (Leptonycteris yerbabuenae)—one in central and the other in the Pacific region of Mexico—differ in their fecal microbiota composition ...
