Data for: Tomato root specialized metabolites evolved through gene duplication and regulatory divergence within a biosynthetic gene cluster
<p>Tremendous plant metabolic diversity arises from phylogenetically-restricted specialized metabolic pathways. Specialized metabolites are synthesized in dedicated cells or tissues, with pathway genes sometimes colocalizing in biosynthetic gene clusters (BGCs). However, the mechanisms by which spatial expression patterns arise and the role of BGCs in pathway evolution remain underappreciated. In this study, we investigated the mechanisms driving acylsugar evolution in the Solanaceae. Previously thought to be restricted to glandular trichomes, acyl sugars were recently discovered in cultivated tomato roots. We demonstrated that acyl sugars in cultivated tomato roots and trichomes have different sugar cores, identified root-enriched paralogs of trichome acyl sugar pathway genes, and characterized a key paralog required for root acyl sugar biosynthesis, <em>SlASAT1-LIKE</em> (<em>SlASAT1-L</em>), which is nested within a previously-reported trichome acyl sugar BGC. Finally, we provided evidence that <em>ASAT1-L</em> arose through duplication of its paralog, <em>ASAT1</em>, and was trichome-expressed before acquiring root-specific expression in the <em>Solanum</em> genus. Our results illuminate the genomic context and molecular mechanisms underpinning metabolic diversity in plants.</p>

Data from: Beech roots are simultaneously colonized by multiple genets of the ectomycorrhizal fungus Laccaria amethystina clustered in two genetic groups
In this study we characterize and compare the genetic structure of aboveground and belowground populations of the ectomycorrhizal fungus Laccaria amethystina in an unmanaged mixed beech forest. Fruiting bodies and mycorrhizas of L. amethystina were mapped and collected in four plots in the Świętokrzyskie Mountains (Poland). A total of 563 fruiting bodies and 394 mycorrhizas were successfully genotyped using the rDNA IGS1 (intergenic spacer) and seven SSR (simple sequence repeat) markers. We identified two different genetic clusters of L. amethystina in all of the plots, suggesting that a process of sympatric isolation may be occurring at a local scale. The proportion of individuals belonging to each cluster was similar among plots aboveground while it significantly differed belowground. Predominance of a given cluster could be explained by distinct host preferences or by priority effects and competition among genets. Both aboveground and belowground populations consisted of many intermingling small genets. Consequently, host trees were simultaneously colonized by many L. amethystina genets that may show different ecophysiological abilities. Our data showed that several genets may last for at least one year belowground and sustain into the next season. Ectomycorrhizal species reproducing by means of spores can form highly diverse and persistent belowground genets that may provide the host tree with higher resilience in a changing environment and enhance ecosystem performance.
