47 results for “fungal symbionts”
Intermediate results for: Large differences in carbohydrate degradation and transport potential among lichen fungal symbionts
<p><span>Lichen symbioses are thought to be stabilized by the transfer of fixed carbon from a photosynthesizing symbiont to a fungus. In other fungal symbioses, carbohydrate subsidies correlate with reductions in plant cell wall-degrading enzymes, but whether this is true of lichen fungal symbionts (LFSs) is unknown. We predicted genes encoding carbohydrate-active enzymes (CAZymes) and sugar transporters in 46 genomes from the </span><em><span>Lecanoromycetes</span></em><span>, the largest extant clade of LFSs. </span><span>All LFSs possess a robust CAZyme arsenal including enzymes acting on cellulose and hemicellulose, confirmed by experimental assays. However, the number of genes and predicted functions of CAZymes vary widely, with some fungal symbionts possessing arsenals on par with well-known saprotrophic fungi. These results suggest that stable fungal association with a phototroph does not in itself result in fungal CAZyme loss, and lends support to long-standing hypotheses that some lichens may </span><span>augment fixed CO</span><span>2</span><span> with carbon from external sources.</span></p>

Figure 4 Haplotype network based on the concatenated sequences of ITS and beta-tubulin of Dasyscyphella longistipitata. The size of the circles represents the haplotype frequency; white dots represent mutational steps between haplotypes (note that the branches lengths do not correspond to genetic distances). Colors represent the locality of origin arranged as a latitudinal gradient where red represents the further north site.

Figure 5 Bayesian Skyride Plot for ADasyscyphella longistipitata using the concatenated ITS and beta-tubulin, and BFagus crenata, using the reported sequences in Fujii et al. (2002). The y-axis represents the scaled effective population size (log10(Ne*u)), and the x-axis represents time as substitutions per site. Shaded area shows the 95% HPD of the posterior distribution. Solid lines show the median value of effective population size. Dotted shades show the upper and lower 95% highest posterior density. Note that the x-axis in A and B are non-equivalent to each other.
