“…The mean number of nematode species was significantly lower in HMG than in UNV (summer, autumn), and the mean nematode abundance increased under Hm while nematode diversity remained unaffected by invasions during the whole study. These results partially agree with our previous findings on related species H. sosnowskyi performed in central Lithuania [34], Poland [35], and the Moscow region of Russia [36] in various habitats. Long-term effects of H. sosnowskyi dominance were associated with decrease in nematode abundance, species, or genera number while nematode diversity remained unaffected by invasions.…”

“…Nematode species diversity was not affected by Hm invasion in our study, nevertheless, many species of native plants were absent in HMG. This finding corresponds with results from H. sosnowskyi invaded habitats in Latvia, Poland, and Russia [34][35][36].…”

“…Unfortunately, to the best of our knowledge, no study has analyzed the impact of Hm invasion on any group of soil organisms or nematode communities. Several recent studies of our research group revealed that Hm botanically related invasive species H. sosnowskyi [34][35][36] or invasive species Reynoutria japonica [45] significantly influenced the structure of nematode communities and the abundance or number of species, indicating that Hm invasion of natural grasslands on river banks might alter soil nematode communities through changes in plant communities and soil properties [23,24,46].…”

“…Together with bacterivores, these are responsible for the higher nematode abundance in the invaded than the uninvaded plots. Similarly, the genus Paratylenchus was more abundant in the forests invaded by H. sosnowskyi [36], or grasslands invaded by S. gigantea [55]. In contrast, [34] reported lower abundances of Paratylenchus nematodes in abandoned land invaded by H. sosnowskyi.…”

“…Therefore, we can only compare the community structure of nematodes inhabiting Hm invaded plots with communities in uninvaded plots located nearby, hoping that both plots had similar plant and nematode composition before the Hm entry. Several previous studies by our research group on the related species H. sosnowskyi carried out in various types of habitats where invasion took place in Lithuania [34], Poland [35], and Russia [36], however, revealed significant shifts in plant species composition, which subsequently modified nematode assemblages and trophic structures. The present study (1) investigated nematode species diversity, abundance, nematode trophic group composition, and nematode food web characteristics in the H. mantegazzianum invaded and related uninvaded riverbank grassland, and (2) evaluated whether long-term H. mantegazzianum invasion affected nematode communities.…”

Heracleum mantegazzianum (giant hogweed) is the largest central European forb, naturalized or invasive in many European countries. The impacts of its colonization of native habitats on soil mesofauna groups are unfortunately obscure. This study assessed the effect of giant hogweed invasion on the communities of plants and soil nematodes in the riparian habitat. We found that invasion by H. mantegazzianum increased soil pH, decreased carbon and nitrogen content, reduced the number and coverage of the native plant species, and influenced nematode communities and their structures. Nematode species number was significantly lower in invaded than uninvaded plots, but nematode species diversity was not affected by invasion throughout the whole study. Total nematode abundance slightly increased under giant hogweed, while total nematode biomass did not differ between the invaded and uninvaded plots. The higher abundance of bacterivores and fungivores but lower number of omnivorous nematodes well represented the negative impact of giant hogweed invasion on soil food webs, supported by low values of all maturity indices or channel index. The hogweed invaded plots contained higher abundance of plant parasitic nematodes, mainly Paratylenchus microdorus. Our results thus indicate that invasion by H. mantegazzianum influences several nematode communities’ parameters while others remain unaffected by invasion.

Heracleum sosnowskyi, belonging to a group of giant hogweeds, is a plant with large effects on ecosystems and human health. It is an invasive species that contributes to the deterioration of grassland ecosystems. The ability of H. sosnowskyi to produce linear furanocoumarins (FCs), photosensitizing compounds, makes it very dangerous. At the same time, linear FCs are compounds with high pharmaceutical value that are used in skin disease therapies. Despite this high importance, it has not been the focus of genetic and genomic studies. Here, we report a chromosome-scale assembly of the Sosnowsky's hogweed genome. Genomic analysis revealed an unusually high number of genes (55 206) in the hogweed genome, in contrast to the 25-35 thousand found in most plants. However, we did not find any traces of recent whole genome duplications not shared with its confamiliar, Daucus carota (carrot), which has approximately thirty thousand genes. The analysis of the genomic proximity of duplicated genes indicates tandem duplications as a main reason for this increase. We performed a genome-wide search of the genes of the FC biosynthesis pathway and their expression in aboveground plant parts. Using a combination of expression data and phylogenetic analysis, we found candidate genes for psoralen synthase and experimentally showed the activity of one of them using a heterologous yeast expression system. These findings expand our knowledge on the evolution of gene space in plants and lay a foundation for further analysis of hogweed as an invasive plant and as a source of FCs.
