[Establishment and optimization of Agrobacterium tumefaciens-mediated genetic transformation system for Polyporus umbellatus].

The unstable quality of Polyporus umbellatus sclerotia during cultivation is the key factor affecting the quality and yield of P. umbellatus sclerotia. In order to provide technical support for obtaining superior P.

, an C2H2 transcription factor from , positively regulates mycelium response to osmotic stress.

is an edible and medicinal mushroom with the capacity to produce sclerotia. However, the mechanism of sclerotia formation is unclear. CRZ1 is a C2H2 family transcription factor involved in the Ca-calcineurin signaling pathway, which has the function of regulating sclerotia formation, maintaining ion homeostasis, and responding to stress.

Isolation, genomic characterization, and mushroom growth-promoting effect of the first fungus-derived .

is a well-known edible and medicinal mushroom, and some bacteria isolated from mushroom sclerotia may have beneficial effects on their host. These mushroom growth-promoting bacteria (MGPBs) are of great significance in the mushroom production. In this work, we aimed to isolate and identify MGPBs from sclerotia.

A Mycorrhizal Bacteria Strain Isolated From Exhibits Broad-Spectrum Antifungal Activity.

The microbes in the rhizosphere (or mycorrhizosphere) could promote plant growth, however, it is unclear whether mycorrhizosphere microbes could fight multiple fungal pathogens. In this study, twenty-one bacterial strains distributed in 6 genera, including 5 strains, were isolated from mycorrhizal samples of that rely on other fungi during their life cycles. Further screening and pot experiments showed that the strain ZL8 not only inhibited the growth of phytopathogenic fungi, but also promoted the growth of through inhibiting its wilting.

Mycorrhizosphere Bacteria, sp. HPDA25, Promotes the Growth of and Its Parasitic Host .

is an entirely heterotrophic plant, the growth of which is completely reliant on , an orchid mycorrhizal fungus. To avoid damaging ecosystems, cultivation is shifting from woodland to farmland. However, whether the microbial community structure remains stable during this conversation is unknown.

Prevalence and Strain Composition of Circulating in Potato Fields in China's North-Central Province of Shanxi.

Potato is an important crop in Shanxi province, located in north-central China. In 2019 to 2020, 319 potato leaf samples were collected from eight locations distributed in three major potato production areas in Shanxi. BioChip testing revealed the presence of several potato viruses, of which (PVY) was the most common, reaching an incidence of 87.
