“…Fungal taxa that were close to Atheliaceae 1 have been detected in the roots of P. densiflora grown in a nursery (Nara and Hogetsu 1996) and in the roots of Pinus thunbergii Parl. in coastal pine forests (Taniguchi et al 2007) and plantations (Obase et al 2010). Several species of Rhizopogon are important EcM symbionts with Pinaceae and are often found as EcM root tips in boreal and temperate pine forests (Gardes and Bruns 1996;Twieg et al 2007).…”

We investigated the ectomycorrhizal (EcM) fungal community of naturally regenerating Pinus densiflora seedlings on exposed decomposed granite (DG) slopes along woodland paths in the Republic of Korea. We sampled threeto five-year-old seedlings from slopes where DG was exposed (habitat S) and from the surrounding forest edge or gaps (habitat F). We classified EcMs into morphological groups and counted the number of root tips. The fungal taxa were determined by sequencing the internal transcribed spacer region of their nuclear rDNA. We observed a total of 27 EcM fungal taxa. Atheliaceae and Rhizopogon were the dominant taxa on exposed DG slopes. The fungal species compositions were similar between habitats (0.59 as calculated by the Morishita-Horn index). Fourteen fungal taxa were common to both habitats, and these accounted for more than 90% of the relative abundance in each habitat. There were no significant differences in relative abundance and colonization frequency of each EcM fungal taxon between the habitats, except for Russula sp. 2, which was significantly more frequent in habitat F than in habitat S. Our results indicated that P. densiflora seedlings on exposed DG slopes associated with EcM fungi that were common in forests and not specific to the exposed DG slopes.

“…The regeneration of Japanese black pine seedlings was also inhibited in a black locust-dominated area (21). The dominant ECM fungi on black pine seedlings were different from those in a black locust-dominated area (19), although most ECM fungi could be detected in soil both in a black pine-dominated and in a black locust-dominated forest (20). Therefore, the difference in the distribution of ECM fungi on the seedlings may influence the regeneration of Japanese black pine.…”

“…The study site was located in the Arid Land Research Center (ALRC), Tottori Sand Dunes, Tottori, Japan (35°32' N, 134°13' E) and was the same as in our previous study (19). Japanese black pine and black locust are dominant at this site, and several plants, Rhus succedanea, Mallotus japonicus, and Celtis sinensis, were also observed.…”

The effects of a nitrogen-fixing tree, black locust (Robinia pseudoacacia), on the distribution of bacterial species were examined in a Japanese black pine (Pinus thunbergii) and black locust-dominated area. DNA was extracted from the soil at depths of 0-5 and 5-10 cm, collected at the border between a Japanese black pine-dominated forest and a black locust-dominated forest, and the distribution of bacterial species was investigated by denaturing gradient gel electrophoresis (DGGE). The bacterial communities did not differ between the two forests. The distribution of some bacterial species correlated significantly with soil pH, soil carbon [C], soil nitrogen [N], and soil N/phosphate [P], but not with soil C/N or soil P. The distributional relationships between ectomycorrhizal (ECM) fungal species and bacterial species were also analyzed. A positive correlation was observed between the distribution of some ECM fungi and bacterial species. These bacteria may have some interactions with ECM fungi in the field.

“…Using molecular tools, several studies have revealed belowground EcM fungal communities in naturally regenerating P. thunbergii seedlings (Taniguchi et al 2007;Matsuda et al 2009b) and mature trees (Obase et al 2009) of coastal pine forests. Matsuda et al (2009a) have described the abundance and distribution of the dominant EcM fungus Cenococcum geophilum Fr.…”

We investigated the diversity and community structure of ectomycorrhizal (EcM) fungi in Pinus thunbergii stands on the eastern coast of Korea. We established two 10 9 10-m plots in six forest stands and sampled soil blocks containing rootlets of mature P. thunbergii trees. EcM roots were classified into morphological groups, and the fungal taxa associated with each morphotype were identified by sequencing the nuclear rDNA internal transcribed spacer region. Cenococcum geophilum and the Atheliales, Clavulinaceae, Russulaceae and Thelephoraceae species were the main members of the EcM fungal community, which included a total of 68 observed fungal taxa. As a whole, the community consisted of a few dominant fungal taxa, such as C. geophilum (28.6% relative abundance), and a large number of rare fungal taxa that showed low abundances and local distributions. Colonization patterns at the local site scale and at the scale of the study plots greatly differed among the EcM fungal taxa; C. geophilum was distributed extensively and was dominant in several study sites, whereas a certain Lactarius sp. was distributed locally but dominated in a given study site. We conclude with a discussion of the relationship between colonization patterns of EcM fungi and soil and environmental conditions.
