Genome assembly of M. spongiola and comparative genomics of the genus Morchella provide initial insights into taxonomy and adaptive evolution.

Morchella spongiola is a highly prized mushroom for its delicious flavor and medical value and is one of the most flourishing, representative, and dominant macrofungi in the Qilian Mountains of the Qinghai-Tibet Plateau subkingdoms (QTPs). However, the understanding of M. spongiola remains largely unknown, and its taxonomy is ambiguous.

Distribution of rhizosphere fungi of on the Qinghai-Tibet Plateau.

is a major species in the alpine meadow communities of the Qinghai-Tibet Plateau (QTP); it plays a crucial role in maintaining the ecological balance of these meadows. Nevertheless, little is known about the rhizosphere fungi associated with on the Qinghai Tibet Plateau. In this study, we used Illumina Miseq to investigate the fungal diversity, community structure, and ecological types in the root and rhizosphere soil of across eight areas on the QTP and analyzed the correlation between rhizosphere fungi of and environmental factors.

Out of the Qinghai-Tibetan plateau: Origin, evolution and historical biogeography of (both Elata and Esculenta clades).

Introduction: Morchella has become a research hotspot because of its wide distribution, delicious taste, and phenotypic plasticity. The Qinghai-Tibet Plateau subkingdoms (QTPs) are known as the cradle of Ice age biodiversity. However, the diversity of Morchella in the QTPs has been poorly investigated, especially in phylogenetic diversity, origin, and biogeography.

The Molecular Mechanism of Yellow Mushroom () Response to Strong Ultraviolet Radiation on the Qinghai-Tibet Plateau.

The Qinghai-Tibet Plateau (QTP) is the highest plateau in the world, and its ultraviolet (UV) radiation is much greater than that of other regions in the world. Yellow mushroom () is a unique and widely distributed edible fungus on the QTP. However, the molecular mechanism of response to strong UV radiation remains unclear.

Microbial response to multiple-level addition of grass organic matter in lake sediments with different salinity.

Water surface expansion of saline lakes usually causes the inundation of surrounding grassland, leading to the increase of terrestrial grass organic matter (OM) input to the lakes and the decrease of lake salinity. However, the influence of terrestrial grass OM input increase and salinity decrease on organic carbon mineralization and microbial community composition remains unknown in saline lakes. Here, microbial mineralization of terrestrial grass (Achnatherum splendens) OM at different quantity levels in lake sediments with different salinity was investigated by performing microcosm experiments.

Soil metabolomics and bacterial functional traits revealed the responses of rhizosphere soil bacterial community to long-term continuous cropping of Tibetan barley.

Continuous cropping often leads to an unbalanced soil microbial community, which in turn negatively affects soil functions. However, systematic research of how these effects impact the bacterial composition, microbial functional traits, and soil metabolites is lacking. In the present study, the rhizosphere soil samples of Tibetan barley continuously monocropped for 2 (CCY02), 5 (CCY05), and 10 (CCY10) years were collected.

Nitrite- and N2O-reducing bacteria respond differently to ecological factors in saline lakes.

The distribution of nitrite- and N2O-reducing bacteria is key to potential N2O emission from lakes. However, such information in highland saline lakes remains unknown. Here, we investigated the abundance and community composition of nitrite- and N2O-reducing bacteria in the sediments of six saline lakes on the Qing-Tibetan Plateau.

Transcriptome Analysis and Expression Profiling of Molecular Responses to Cd Toxicity in .

is a genus of fungi with the ability to concentrate Cd both in the fruit-body and mycelium. However, the molecular mechanisms conferring resistance to Cd stress in are unknown. Here, RNA-based transcriptomic sequencing was used to identify the genes and pathways involved in Cd tolerance in .

Morphological changes and bioaccumulation in response to cadmium exposure in , a fungus with potential for detoxification.

is a genus of edible fungi with strong resistance to cadmium (Cd) and the ability to accumulate it in its mycelia. However, the mechanisms underlying Cd resistance in remain unknown. In the present study, morphological and physiological responses to Cd were evaluated in the mycelia of .

Minerals play key roles in driving prokaryotic and fungal communities in the surface sediments of the Qinghai-Tibetan lakes.

There is limited knowledge of the relative influences of deterministic and stochastic processes on prokaryotic and fungal communities in lake sediments. In this study, we surveyed the prokaryotic and fungal community compositions and their influencing factors in 23 surface sediments from six lakes on the Qinghai-Tibetan Plateau (QTP) with the use of Illumina sequencing. The results showed the distribution of prokaryotic and fungal communities in the studied QTP lake sediments was shaped by different assembly processes, with prokaryotes primarily governed by variable selection and homogenizing dispersal (accounting for 57.

Surviving onshore soil microbial communities differ among the Qing-Tibetan lakes with different salinity.

Little is known about the onshore microbial contribution to the microbial communities in nearby lakes and its response to salinity. In this study, transplanting experiments were established by caging onshore soils with dialysis bags followed by in situ 50-day incubation in nearby lakes with different salinity on the Qinghai-Tibetan Plateau. At the end of the experiment, geochemical and microbial analyses were performed on the original soils, caged soils and lake waters and sediments at the incubation sites.
