Defensive symbiosis in the wild: seasonal dynamics of parasitism risk and symbiont-conferred resistance
<p class="MsoNormal"><span>Parasite-mediated selection can rapidly drive up resistance levels in host populations, but fixation of resistance traits may be prevented by costs of resistance. Black bean aphids (<em>Aphis fabae</em>) benefit from increased resistance to parasitoids when carrying the defensive bacterial endosymbiont <em>Hamiltonella defensa</em>. However, due to fitness costs that come with symbiont infection, symbiont-conferred resistance may result in either a net benefit or a net cost to the aphid host, depending on parasitoid presence as well as on the general ecological context. Balancing selection may therefore explain why in natural aphid populations, <em>H. defensa</em> is often found at intermediate frequencies.<strong> </strong>Here we present a two-year field study where we set out to look for signatures of balancing selection in natural aphid populations. We collected temporally well-resolved data on the prevalence of <em>H. defensa</em> in <em>A.f. fabae</em> and estimated the risk imposed by parasitoids using sentinel hosts.<strong> </strong>Despite a marked and consistent early-summer peak in parasitism risk and significant changes in symbiont prevalence over time, we found just a weak correlation between parasitism risk and <em>H. defensa </em>frequency dynamics. <em>H. defensa </em>prevalence in the populations under study was, in fact, better explained by the number of heat days that previous aphid generations were exposed to.<strong> </strong>Our study grants an unprecedentedly well-resolved insight into the dynamics of endosymbiont and parasitoid communities of <em>A.f. fabae </em>populations, and it adds to a growing body of empirical evidence suggesting that not only parasitism risk but rather multifarious selection is shaping <em>H. defensa</em> prevalence in the wild.</span></p>

Phosphorus nutrition strategies in a symbiodiniacean species: Implications in coral-alga symbiosis facing increasing phosphorus deficiency in future warmer oceans
<p><span>Coral reefs thrive in the oligotrophic ocean and rely on symbiotic algae to acquire nutrients. </span><span>Global warming is projected to intensify surface ocean nutrient deficiency and anthropogenic discharge of wastes with high nitrogen (N): phosphorus (P) ratios can exacerbate P nutrient limitation. However, our understanding on how symbiotic algae cope with P deficiency is limited. Here, we </span><span>investigated the responses of a coral symbiotic species of <em>Symbiodiniaceae, Cladocopium goreaui</em>, to P-limitation by examining its physiological performance and transcriptomic profile. </span><span>Under P stress, <em>C. goreaui</em> exhibited decreases in algal growth, photosynthetic efficiency, and cellular P content but enhancement in carbon fixation, N assimilation, N:P ratio, and energy metabolism, with downregulated expression of carbohydrate exporter genes. Besides, <em>C. goreaui </em>showed flexible mechanisms of utilizing different dissolved organic phosphorus to relieve P deficiency. When provided glycerol phosphate,<em> C. goreaui</em> hydrolyzed it extracellularly to produce phosphate for uptake. When grown on phytate, in contrast, <em>C. goreaui</em> upregulated the endocytosis pathway while no dissolved inorganic phosphorus was released into the medium, suggesting that phytate was transported into the cell, potentially via the endocytosis pathway. This study sheds light on the survival strategies of <em>C. goreaui</em> and potential weakening of its role as an organic carbon supplier in P-limited environments, underscoring the importance of more systematic investigation on future projections of such effects.</span></p>
The evolution of ectomycorrhizal symbiosis in the Late Cretaceous is a key driver of explosive diversification in Agaricomycetes
<p>Ectomycorrhizal (EcM) symbiosis is one of the most ubiquitous and important plant–microbe interactions in forest ecosystems. Coevolutionary interactions often create new ecological opportunities for explosive diversification. It remains unclear why the evolution of EcM fungi did not necessarily increase ecological opportunities for explosive diversification. This study aims to reveal the driving mechanism of the explosive diversification in the fungal class Agaricomycetes, specifically by testing whether the evolution of EcM symbiosis in the Late Cretaceous increased ecological opportunities. Molecular phylogenies of Agaricomycetes inferred from fragments of 89 single-copy genes indicate that the unidirectional evolution of EcM symbiosis occurred multiple times, ranging in date from the early Triassic to the early Paleogene. However, five analyses for estimating net diversification rates (speciation rates minus extinction rates) suggest that the explosive diversification occurred only at the stem EcM fungal clades diverging in the late Cretaceous, coinciding with the rapid diversification of EcM angiosperms. The present findings suggest that the evolution of EcM symbiosis, supposedly with coevolving EcM angiosperms, in the Late Cretaceous was the key drive of the explosive diversification in Agaricomycetes.</p>
