• Increased susceptibility of Norway spruce to pathogen infection under drought conditions is linked to transcriptional responses related to carbon metabolism · 2026

  Résumé de la publication : Tree mortality and susceptibility to pathogens often increases under drought conditions. The interactive nature of these stressors is thought to be related to the balance between sinks and sources of non-structural carbon (NSC), such as defence and osmoregulation versus photosynthesis, respectively. Here,…

• Uromyces plumbarius first reported on Oenothera lindheimeri in Europe with widespread distribution and association with two common natural enemies of rust fungi · 2026

  Résumé de la publication : The rust fungus Uromyces plumbarius Peck was reported in Europe for the first time on Oenothera lindheimeri (Engelm. & A. Gray) W.L. Wagner & Hoch (Lindheimer's beeblossom), a highly popular ornamental plant widely cultivated since the 2000s. The fungus was found in…

• Biochar amendment improves Morchella sextelata yield by enhancing soil NO3--N availability and increasing the diversity while decreasing the absolute abundance of fungal community · 2026

  Résumé de la publication : Black morel (Morchella sextelata) is widely regarded as a post-fire mushroom because of its prolific fruiting in post-fire forest soils enriched with charcoal. Intriguingly, artificial cultivation of M. sextelata often incorporates biochar as a soil amendment to enhance yield, although the underlying…

• Mycorrhizal competition release and microbial dynamics in native and nonnative Tuber melanosporum habitats · 2026

  Résumé de la publication : Truffles in the genus Tuber (Pezizales) are among the few ectomycorrhizal taxa successfully cultivated worldwide. Australia has recently become one of the top producers of Tuber melanosporum, a high-valued black truffle native to Europe.Introductions in the Southern Hemisphere are hypothesized to benefit…

• Multi-omics reveals nitrate-induced oxidative stress and morphogenesis pathways in Morchella importuna · 2026

  Résumé de la publication : Nitrate (NO 3 − ) and ammonium (NH 4 + ) are the two main forms of inorganic nitrogen (N) found in soil. Most macrofungi show a preference for specific forms of N; however, the mechanisms behind these preferences remain poorly understood.…
