Variability in nutrient use by orchid mycorrhizal fungi in two medium types
<p><span>Orchid mycorrhizal fungi (OMF) from the rhizoctonia aggregate are generally considered to be soil saprotrophs, but their ability to utilize various nutrient sources has been studied in a limited number of isolates cultivated predominantly in liquid media, although rhizoctonia typically grow on the surface of solid substrates. Nine isolates representing the key OMF families (Ceratobasidiaceae, Tulasnellaceae and Serendipitaceae), sampled in Southern France and the Czech Republic, were tested for their ability to utilize carbon (C), nitrogen (N) and phosphorus (P) sources <em>in</em> <em>vitro</em> in both liquid and solid media. The isolates showed significant inter- and intra-familiar variability in nutrient utilization, most notably in N sources. Isolates produced generally larger amounts of dry biomass on solid medium than in liquid one, but some isolates showed no or limited biomass production on solid medium with particular nutrient sources. The largest amount of biomass was produced by isolates from the family Ceratobasidiaceae on most sources in both medium types. The biomass production of Tulasnellaceae isolates was affected by their phylogenetic relatedness on all sources and medium types. The ability of isolates to utilize particular nutrients in a liquid medium but not a solid one should be considered when optimizing solid media for symbiotic orchid seed germination and in understanding of OMF functional traits under in situ conditions.</span></p>
FIGURE 2 in Hundreds of nuclear and plastid loci yield novel insights into orchid relationships.
FIGURE 2. Species-coalescence tree of the orchid family inferred from 292 maximum likelihood (ML) gene trees. Pie diagrams at nodes represent quartet support values, with q1 (deep blue portion) representing the proportion of gene tree quartets that support the main (depicted) branch, q2 (blue portion) representing the proportion of quartets supporting the first alternative branch, and q3 (gray portion) representing the proportion of quartets supporting the second alternative branch (an explanation of how the quartet values are computed is available at https://github.com/smira rab/ASTRAL/blob/master/astral-tutorial.md). (Inset): ML tree derived from a supermatrix of 292 low copy nuclear genes. Terminal names with alternative positions to those obtained by the species-tree coalescence analysis are highlighted in bold and red. Adetailed version of the tree is presented in Appendix S4.
