“…Mycorrhizal fungi build reciprocally beneficial (symbiotic) associations with more than 80% of plant species, and these fungi can colonize the host plant’s root tissues either intracellularly as in arbuscular mycorrhiza, which is associated with Glomeromycota , or extracellularly as in ectomycorrhiza, which is associated with Basidiomycota and Ascomycota [ 25 ]. Mycorrhizal fungi are known to help trees to cope with upcoming climate change [ 26 , 27 ] by extending plants’ root areas (thus accelerating biogeochemical cycles) as well as by enhancing water and mineral nutrient (nitrogen and phosphorus) uptake by the plant [ 22 ]. Due to these properties, mycorrhiza is considered an important and eco-friendly biofertilizer that contributes to sustainable agriculture and forestry by mitigating abiotic and biotic stress in plants [ 22 , 28 ].…”

The physiological and biochemical responses of pedunculate oaks (Quercus robur L.) to heat stress (HS) and mycorrhization (individually as well in combination) were estimated. One-year-old Q. robur seedlings were grown under controlled conditions in a pot experiment, inoculated with a commercial inoculum of ectomycorrhizal (ECM) fungi, and subjected to 72 h of heat stress (40 °C/30 °C day/night temperature, relative humidity 80%, photoperiod 16/8 h) in a climate chamber, and they were compared with seedlings that were grown at room temperature (RT). An in-depth analysis of certain well-known stress-related metrics such as proline, total phenolics, FRAP, ABTS, non-protein thiols, and lipid peroxidation revealed that mycorrhized oak seedlings were more resistant to heat stress (HS) than non-mycorrhized oaks. Additionally, levels of specific polyamines, total phenolics, flavonoids, and condensed tannins as well as osmotica (proline and glycine betaine) content were measured and compared between four treatments: plants inoculated with ectomycorrhizal fungi exposed to heat stress (ECM-HS) and those grown only at RT (ECM-RT) versus non-mycorrhized controls exposed to heat stress (NM-HS) and those grown only at room temperature (NM-RT). In ectomycorrhiza inoculated oak seedlings, heat stress led to not only a rise in proline, total phenols, FRAP, ABTS, non-protein thiols, and lipid peroxidation but a notable decrease in glycine betaine and flavonoids. Amounts of three main polyamines (putrescine, spermine, and spermidine) were quantified by using high-performance liquid chromatography coupled with fluorescent detection (HPLC/FLD) after derivatization with dansyl-chloride. Heat stress significantly increased putrescine levels in non-mycorrhized oak seedlings but had no effect on spermidine or spermine levels, whereas heat stress significantly increased all inspected polyamine levels in oak seedlings inoculated with ectomycorrhizal inoculum. Spermidine (SPD) and spermine (SPM) contents were significantly higher in ECM-inoculated plants during heat stress (approximately 940 and 630 nmol g−1 DW, respectively), whereas these compounds were present in smaller amounts in non-mycorrhized oak seedlings (between 510 and 550 nmol g−1 DW for Spd and between 350 and 450 nmol g−1 DW for Spm). These findings supported the priming and biofertilizer roles of ectomycorrhizal fungi in the mitigation of heat stress in pedunculate oaks by modification of polyamines, phenolics, and osmotica content.

“…Fifty years previous to Ruščić (2003), Piškorić (1953) reported the experiment assigned to Secondary forestry school for karst in Split (Srednja šumarska škola za krš u Splitu) by the Federal Administration for Production Improvement (Savezna uprava za unapređenje proizvodnje). The experiment consisted of testing the influence of sea spray on kudzu (as Pueraria hirsuta ) and it was conducted during 1951 and 1952.…”

Kudzu vine (Pueraria montana var. lobata; Fabaceae) was included on the list of invasive alien species of (European) Union concern in 2016, according to EU Regulation 1143/2014 on the prevention and management of the introduction and spread of invasive alien species. In the Flora Croatica Database this species is recorded under its synonym Pueraria thunbergiana Benth. for Split (Central Dalmatia), so its presence in Croatia was overlooked until it was discovered in Malinska on the island of Krk in August 2018. Recent field observations confirm that, in addition to Malinska, it is also present in Šestanovac (Central Dalmatia), the Trsteno Arboretum and in Dubrovnik (South Dalmatia). Localities in Gradac and Seget (Central Dalmatia) were also recently discovered. Literature and herbaria data as well as internet resources indicate that kudzu vine has been historically grown as an ornamental species in Croatia. Considering its invasiveness as reported in several countries and its ornamental uses, other unknown localities of cultivated or naturalized kudzu vine could exist along the Croatian coast.

“…Fungi are highly diverse and crucial for a wide variety of ecosystem services. They are one of the largest groups of decomposers, playing an essential role in nutrient cycling as saprotrophs or mycorrhiza, and facilitating ecosystem feedback to climate changes 1 – 4 . Fungi are a species-rich taxon of approximately 2.2–3.8 million species 5 , lesser in number to only compared with terrestrial arthropods (over 7 million species 6 ).…”

The history of fungal diversity of the Northeastern United States is currently fragmentary and restricted to particular functional groups or limited geospatial scales. Here, we describe a unique by its size, lifespan and data originators dataset, to improve our understanding of species occurrence and distribution across the state and time. Between the years 2007 to 2019, over 30 parks and nature preserves were sampled during forays conducted by members of the New Jersey Mycological Association (USA), a nonprofit organization of fungi enthusiasts. The dataset contains over 400 000 occurrences of over 1400 species across the state, made up mostly of the phylum Basidiomycota (89%) and Ascomycota (11%), with most observations resolved at the species level (>99%). The database is georeferenced and openly accessible through the Global Biodiversity Information Facility (GBIF) repository. This dataset marks a productive endeavor to contribute to our knowledge of the biodiversity of fungi in the Northeastern United States leveraging citizen science to better resolve biodiversity of this critical and understudied kingdom.
