“…Several authors attempted artificial inoculation of blueberries with selected strains of ericoid mycorrhizal fungi [18,21], but this did not always lead to an increased growth and/or fruit production. Positive results may be obtained when mineral fertilizers are substituted by organic matter input [26], but even then the effect of soil saprotrophic fungi decomposing the introduced organic matter on blueberry growth and fruiting may be higher than that of true ErM fungi [28].…”

Abstract. BACKGROUND:European blueberry (Vaccinium myrtillus L.; EB) is one of the most common shrubs in Nordic forests. It has been exploited through centuries by man and is considered a valuable food. However, it has not been domesticated and all EB fruit is harvested from forest fields. The investigations reported here were undertaken to examine the possibility of EB domestication. OBJECTIVE: With the aid of knowledge achieved through examinations of EB in natural forests and in cultivated fields of lowbush blueberry, the following trials were started to examine if EB could be grown on rich farmland by adaption of fertilization and addition of natural peat as mulch; and by planting EB mats from a forest field and EB seedlings in a strip of top soil (O-layer) from the same field, with the aim to introduce ericoid mycorrhizal (ErM) fungi. METHOD:The experiments were performed as two field trials (A and B) on agricultural land. Trial A was a block design with four replications, examining the effect on plant growth of nine randomly broadcasted fertilization levels combining nitrogen and phosphorus on fresh planted EB seedlings. In addition, two out of four blocks were randomly mulched with natural peat. Trial B was a split-plot design with three blocks. Each block consisted of two large plots and each large plot contained two small plots. Two fertilization levels were randomly broadcasted in large plots, and two plant types [small plug seedlings propagated in sparsely fertilized peat; and mats of (30 × 20) cm 2 from a nearby forest field existing of O-layer and some of the E-layer (wash out soil layer)] were randomly planted in small plots. Seedling plants of trial B (similar plants as in Trial A) were planted in shallow furrows filled with forest soil. Fertilization were N0P0 (control; no fertilizer), and N1P1 (fertilized similar to a medium treatment of trial A). The seedling plants were in a juvenile phase in the year of planting, but the first fruits were observed in the third field year. This indicate that the plants had entered the generative phase. RESULTS: In trial A fertilization increased spatial growth of EB plants and fruit number. However, P alone did not have any significant effect since the level in the soil was high already before establishing the experimental field. Fertilizing with N alone was most effective in terms of spatial growth and fruit number. However, when P fertilizer was applied together with N fertilizer, plant growth and fruit number increased more than when N was applied alone. Fertilization also increased levels of P and S in the soil. Top-dressing had positive effect on growth in the non-fertilized plots. Fertilization of top-dressed plots resulted in poorer plant growth except for N alone and strongest combined fertilization, and there was no clear effect on fruit number. In plots that were not fertilized top-dressing increased total amount of C, N, Ca and Mg. In trial B mycorrhiza was present in all plots and probably influenced the uptake of nutrients by EB. It is of interest...

Experimental evidence of ericoid mycorrhizal potential within Serendipitaceae (Sebacinales)

The Sebacinales are a monophyletic group of ubiquitous hymenomycetous mycobionts which form ericoid and orchid mycorrhizae, ecto- and ectendomycorrhizae, and nonspecific root endophytic associations with a wide spectrum of plants. However, due to the complete lack of fungal isolates derived from Ericaceae roots, the Sebacinales ericoid mycorrhizal (ErM) potential has not yet been tested experimentally. Here, we report for the first time isolation of a serendipitoid (formerly Sebacinales Group B) mycobiont from Ericaceae which survived in pure culture for several years. This allowed us to test its ability to form ericoid mycorrhizae with an Ericaceae host in vitro, to describe its development and colonization pattern in host roots over time, and to compare its performance with typical ErM fungi and other serendipitoids derived from non-Ericaceae hosts. Out of ten serendipitoid isolates tested, eight intracellularly colonized Vaccinium hair roots, but only the Ericaceae-derived isolate repeatedly formed typical ericoid mycorrhiza morphologically identical to ericoid mycorrhiza commonly found in naturally colonized Ericaceae, but yet different from ericoid mycorrhiza formed in vitro by the prominent ascomycetous ErM fungus Rhizoscyphus ericae. One Orchidaceae-derived isolate repeatedly formed abundant hyaline intracellular microsclerotia morphologically identical to those occasionally found in naturally colonized Ericaceae, and an isolate of Serendipita (= Piriformospora) indica produced abundant intracellular chlamydospores typical of this species. Our results confirm for the first time experimentally that some Sebacinales can form ericoid mycorrhiza, point to their broad endophytic potential in Ericaceae hosts, and suggest possible ericoid mycorrhizal specificity in Serendipitaceae.

“…Extracts directly isolated from blueberry plants (Vaccinium species) indicated good antioxidant (Elfar et al 2013;Miao et al 2013;Stewart et al 2015;Tadych et al 2012) as well as antimicrobial activities (Ermis et al 2015;Girardot et al 2014;Kalt et al 2007;Puišo et al 2014;Silva et al 2013). Many endophytic fungi have been isolated and characterized from Vaccinium spp., some of them belonging to pathogenic fungi whereas others are beneficial fungi (Farr et al 2002;Jeffers 1991;Miao et al 2013;Reeh & Cutler 2013;Sauer et al 2002;Tadych et al 2012;Vohnik et al 2012). Furthermore, several natural products from these fungi have been identified, such as griseofulvin, flavonoids and bioactive polyketides (Li et al 2009;Richardson et al 2014;Sauer et al 2002).…”

Fungi associated with Vaccinium species play important roles in plant growth and disease control, especially in the final blueberry production. Vaccinium dunalianum var. urophyllum (Ericaceae) is a well-known medicinal plant in Southern China used to treat inflammation and microbial infections. The endophytic fungi from these plants are therefore anticipated as potential new sources of antimicrobials. In this report, the inhibitory effects of endophytes against clinical bacteria and yeast were comprehensively screened and 11 isolates indicated high bioactivity by the agar diffusion method. The corresponding crude extracts of these fungi under submerged fermentation also demonstrated distinct differences and n-butyl alcohol displayed the lowest extraction efficiency among the extracts. The ethyl acetate and dichloromethane extracts of filtrates from the Colletotrichum sp. VD001, Epicoccum nigrum VD021 and E. nigrum VD022 strains displayed good properties against pathogenic microorganisms according to disc diffusion assays and minimal inhibitory concentration (MIC). This study is the first indicating that cultivable endophytic fungi associated with blueberry plants produce potential compounds against clinical pathogens. ABSTRAKKulat yang dikaitkan dengan spesies Vaccinium memainkan peranan penting dalam pertumbuhan tumbuhan dan kawalan penyakit, terutamanya dalam pengeluaran beri biru akhir. Vaccinium dunalianum var. urophyllum (Ericaceae) ialah tumbuhan ubatan yang terkenal di Selatan China yang digunakan untuk merawat jangkitan keradangan dan mikrob. Oleh itu, kulat endofit daripada tumbuhan ini dijangka sebagai sumber baru antimikrob yang berpotensi. Dalam laporan ini, kesan perencatan endofit terhadap bakteria klinikal dan suatu ragi telah ditayangkan secara komprehensif dan 11 pencilan menunjukkan bioaktiviti tinggi melalui kaedah penyebaran agar. Ekstrak mentah yang sepadan dengan kulat ini di bawah penapaian terendam juga menunjukkan perbezaan yang ketara serta n-butil alkohol menunjukkan kecekapan pengekstrakan terendah dalam kalangan ekstrak. Ekstrak etil asetat dan diklorometana filtrat daripada Colletotrichum sp. VD001, Epicoccum nigrum VD021 dan E. nigrum VD022 menunjukkan sifat-sifat yang baik terhadap mikroorganisma patogen berdasarkan ujian penyebaran cakera dan kepekatan perencatan minimum (MIC). Kajian ini adalah kajian yang pertama menunjukkan bahawa kulat endofit yang boleh dikaitkan dengan tumbuhan beri biru menghasilkan sebatian yang berpotensi terhadap patogen klinikal.Kata kunci: Aktiviti antimikrob; kepekatan perencatan minimum; kulat endofit; spesies Vaccinium
