“…The most abundant identified order of these shared OTUs, the Mortierellales, is globally ubiquitous, and has been found in diverse environments such as in snow mats [77], compost [78], and urban soils [52]. They have also been documented as both saprotrophs and endophytes [79,80], demonstrating their metabolic flexibility. The Mortierellales are also a basal fungal lineage containing some of the oldest sporocarp formers [79], which may contribute to their widespread occurrence.…”

Responses of Soil Fungi to Logging and Oil Palm Agriculture in Southeast Asian Tropical Forests

Human land use alters soil microbial composition and function in a variety of systems, although few comparable studies have been done in tropical forests and tropical agricultural production areas. Logging and the expansion of oil palm agriculture are two of the most significant drivers of tropical deforestation, and the latter is most prevalent in Southeast Asia. The aim of this study was to compare soil fungal communities from three sites in Malaysia that represent three of the most dominant land-use types in the Southeast Asia tropics: a primary forest, a regenerating forest that had been selectively logged 50 years previously, and a 25-year-old oil palm plantation. Soil cores were collected from three replicate plots at each site, and fungal communities were sequenced using the Illumina platform. Extracellular enzyme assays were assessed as a proxy for soil microbial function. We found that fungal communities were distinct across all sites, although fungal composition in the regenerating forest was more similar to the primary forest than either forest community was to the oil palm site. Ectomycorrhizal fungi, which are important associates of the dominant Dipterocarpaceae tree family in this region, were compositionally distinct across forests, but were nearly absent from oil palm soils. Extracellular enzyme assays indicated that the soil ecosystem in oil palm plantations experienced altered nutrient cycling dynamics, but there were few differences between regenerating and primary forest soils. Together, these results show that logging and the replacement of primary forest with oil palm plantations alter fungal community and function, although forests regenerating from logging had more similarities with primary forests in terms of fungal composition and nutrient cycling potential. Since oil palm agriculture is currently the mostly rapidly expanding equatorial crop and logging is pervasive across tropical ecosystems, these findings may have broad applicability.

This study focuses at the effect of forest fire on the extent of ectomycorrhizal (EcM) colonization of Pinus koraiensis. The EcM fungal diversity was estimated di rectly from mycorrhizas using molecular techniques. The revealed EcM fun gal community was highly diverse, with 110 operational taxonomic units de tec ted. The members of Russulaceae and Thelephoraceae were among the most dominant species in both the fire and control sites. The most diverse ba si dio my cete EcM genera at the burned sites were Tomentella, Russula, Piloderma, Inocybe, Sui llus, Sebacina and Lactarius. Mycorrhizal colonization was found to be high for seed lings grown at the burned and the unburned sites. However, there was a ra ther significant shift between sites in terms of the taxonomic composition of EcM symbionts as well as the dominant fungal species. A vertical stratification of EcM fungal diversity at the control site and the sites of later succession stages was found to be more leveled. The results of the study indicate that EcM fungi ap pa rently play an important role in the processes of regeneration of natural fo rest stands after fire at the studied area. . Целью исследования было изучение эффекта воз дейст вия по жара на степень эктомикоризной (ЭМ) колонизации корней Pi nus koraiensis. Идентификация ЭМ компонента производилось не по сред ст вен но из микоризных окончаний с использованием молекулярных ме тодов. Со об щества ЭМ грибов, ассоциированные с корнями P. koraiensis, были весьма раз но об разны. Всего было обнаружено 110 операционных таксономических еди ниц (ОТE). Преобладающими по числу видов семействами во всех изу чен ных сообществах, включая контроль, оказались Russulaceae и Thelephoraceae. Наи более богатыми по видовой представленности родами были Tomentella, Rus su la, Piloderma, Inocybe, Suillus, Sebacina и Lactarius. Было установлено, что степень ми ко риз ной колонизации сеянцев в сообществах, подвергшихся пожару, и в не го рев ших участках была высокой. Выявлена разница между изученными сооб щест вами в таксономическом составе и в составе доминирующих видов ЭМ симбионтов, образующих микоризную связь с сеянцами. Было оценено вер ти каль ное распределение мицелия ЭМ грибов в горизонтах почвы. По ка за но, что это распределение выглядит более выровненным в ненарушенных лесах и на более поздних стадиях сукцессии. Результаты проведенного исследования по ка зывают, что ЭМ грибы играют важную роль в процессах регенерации при род ных древостоев после пожаров.

“…Genus Mortierella needs a thorough revision based on at least a multiple gene phylogeny. Genome sequencing of mortierellalean fungi would also elucidate the origin of fungal fruit bodies, which apparently first occurred in this group [11]. Genome data will help us to understand the role of these fungi in natural ecosystems, and to utilize their industrial potential (production of poly-unsaturated fatty acids) more efficiently.…”
