Intraspecific variation in symbiont density in an insect–microbe symbiosis [PDF]

open access: yesMolecular Ecology, 2021
Many insects host vertically transmitted microbes, which can confer benefits to their hosts but are costly to maintain and regulate. A key feature of these symbioses is variation: for example, symbiont density can vary among host and symbiont genotypes ...

Symbionts of Ciliates and Ciliates as Symbionts

Indian Journal of Microbiology
Endosymbiotic relationships between ciliates and others are critical for their ecological roles, physiological adaptations, and evolutionary implications. These can be obligate and facultative. Symbionts often provide essential nutrients, contribute to the ciliate's metabolism, aid in digestion, and offer protection against predators or environmental ...

Swapping symbionts in spittlebugs: evolutionary replacement of a reduced genome symbiont [PDF]

open access: yesISME Journal, 2014
Abstract Bacterial symbionts that undergo long-term maternal transmission experience elevated fixation of deleterious mutations, resulting in massive loss of genes and changes in gene sequences that appear to limit efficiency of gene products.

Screening Salamanders for Symbionts

2022
Microbial symbionts are broadly categorized by their impacts on host fitness: commensals, pathogens, and mutualists. However, recent investigations into the physiological basis of these impacts have revealed nuanced microbial influences on a wide range of host developmental, immunological, and physiological processes, including regeneration.

Archaeal symbionts and parasites

Current Opinion in Microbiology, 2011
Several species of Archaea are involved in symbiotic or parasitic associations with representatives of Eukarya, Bacteria and other Archaea. Eukaryal interactions include different members of methanogens, found in the gut of arthropods, in the rumen of cattle, and in the human intestine, while Cenarchaeum symbiosum is a partner of a marine sponge ...

Pollen. Symbionts and Symbiont-Induced Structures

1985
Pollen grains, the male gametophytes of plants, are free structures for a portion of their life history. At maturity, the pollen is released from the anther in angiosperms, or the microsporangium in gymnosperms, and is carried by wind, insects, or other agents to the receptive surface of the female part of the plant, namely the stigma in flowering ...
