Data described in the article "Unraveling the diversity of hyphal explorative traits among Rhizophagus irregularis genotypes"

<p>The dataset includes supplementary Figures, tables and the results of two experiments published in the study titled "Unraveling the diversity of hyphal explorative traits among Rhizophagus irregularis genotypes", available here: https://doi.org/10.1007/s00572-024-01154-8</p> <p>The study compares seven homokaryotic isolates (genotypes) of Rhizophagus irregularis, aiming to characterize the range of intraspecific variability with respect to hyphal exploration of organic nitrogen (N) resources, and N supply to plants. Two experiments (one in vitro and one in open pots) were conducted, and 15N-chitin as the isotopically labeled&nbsp;organic N source was used.</p> <p>Experiment 1 (in vitro), mycelium of all arbuscular mycorrhizal (AM) fungal genotypes transferred a higher amount of 15N to the plants than the passive transfer of 15N measured in the non-mycorrhizal (NM) controls. Noticeably, certain genotypes (e.g., LPA9) showed higher extraradical mycelium biomass production but not necessarily greater 15N acquisition than the others.&nbsp;</p> <p>Experiment 2 (in pots) highlighted that some of the AM fungal genotypes (e.g., MA2, STSI) exhibited higher rates of targeted hyphal exploration of chitin-enriched zones, indicative of distinct N exploration patterns from the other&nbsp;genotypes. Dataset contain photos and other recorded parameters during the experiment 1 and experiment 2.</p>
