Many microbial symbionts have multiple phenotypic consequences for their
animal hosts. However, the ways in which different symbiont-mediated
phenotypes combine to affect fitness are not well understood. We
investigated whether there are correlations between different
symbiont-mediated phenotypes. We used the symbiont Spiroplasma, a striking
example of a bacterial symbiont conferring diverse phenotypes on insect
hosts. We took 11 strains of Spiroplasma infecting pea aphids
(Acyrthosiphon pisum) and assessed their ability to provide protection
against the fungal pathogen Pandora neoaphidis and the parasitoids
Aphidius ervi and Praon volucre. We also assessed effects on male
offspring production for five of the Spiroplasma strains. All but one of
the Spiroplasma strains provided very strong protection against the
parasitoid P. volucre. As previously reported, variable protection against
P. neoaphidis and A. ervi was also present; male-killing was likewise a
variable phenotype. We find no evidence of any correlation, positive or
negative, between the different phenotypes, nor was there any evidence of
an effect of symbiont phylogeny on protective phenotype. We conclude that
multiple symbiont-mediated phenotypes can evolve independently from one
another without trade-offs between them.
Dataset comprises the raw data collected for the associated published
manuscript, and methods are as described in that publication.
Resistance to Aphidius ervi: Spiroplasma_Aphidius_data_txt Raw data
collected on effects of Spiroplasma strains on aphid resistance to
Aphidius ervi. The heading 'block' refers to the temporal block
and 'replicate' to a single dish of aphids attacked by a single
female parasitoid. Resistance to Pandora
neoaphidis: Spiroplasma_Pandora_data_txt Raw data collected on effects of
Spiroplasma strains on aphid resistance to Pandora neoaphidis. D0 = number
of aphids exposed to fungus; D2, D4 ... D8 = number of aphids surviving on
day 2, day 4 ... day 8 post-exposure. Resistance to Praon
volucre: Spiroplasma_Praon_data_txt Raw data collected on effects of
Spiroplasma strains on aphid resistance to Praon volucre. The heading
'block' refers to the temporal block and 'replicate'
to a single dish of aphids attacked by a single female parasitoid.
Male-killing: Spiroplasma_male_killing_da... Raw data collected on effects
of Spiroplasma strains on male offspring production.
