forms a mutualistic symbiotic association with . This biotrophic fungus systemically colonizes the intercellular spaces of aerial tissues to form an endophytic hyphal network and also grows as an epiphyte. However, little is known about the cell wall-remodeling mechanisms required to avoid host defense and maintain intercalary growth within the host. Here, we use a suite of molecular probes to show that the cell wall is remodeled by conversion of chitin to chitosan during infection of seedlings, as the hyphae switch from free-living to endophytic growth. When hyphae transition from endophytic to epiphytic growth, the cell wall is remodeled from predominantly chitosan to chitin. This conversion from chitin to chitosan is catalyzed by chitin deacetylase. The genome of encodes three putative chitin deacetylases, two of which ( and ) are expressed in planta. Deletion of either of these genes results in disruption of fungal intercalary growth in the intercellular spaces of plants infected with these mutants. These results establish that these two genes are required for maintenance of the mutualistic symbiotic interaction between and .[Formula: see text] Copyright © 2021 The Author(s).

Texture is an important quality index reflecting a series of sensory evaluations of fruit, and softening is the main texture change of most postharvest fruit. Persimmon fruit () shows a pattern of decreasing firmness after harvest, leading to a short duration of sale and excessive waste. We found that the treatment with gibberellin (GA) could effectively inhibit the postharvest softening of persimmon fruit, but the underlying mechanism is unclear.

Mycobacterium tuberculosis causes human tuberculosis. As mycobacteria are protected by thick lipid cell wall, humans have developed immune responses against diverse mycobacterial lipids. Most of these immunostimulatory lipids are known as adjuvants acting through innate immune receptors, such as C-type lectin receptors.

Four salt-tolerant and aromatics degrading strains used in this study were isolated from polluted technogenic soil on the territory of the Verkhnekamsk potash deposit (Russia). The strains were aerobic, Gram-stain-positive, non-motile, non-endospore-forming irregular rods, exhibiting a marked rod-coccus growth cycle. They contained lysine-based peptidoglycan, teichulosonic acid and poly(glycosyl phosphate) polymers in the cell walls.

A Gram-staining-positive, aerobic bacterium, designated strain JJ-181, was isolated from the root surface of soybean. Based on the 16S rRNA gene sequence similarities, strain JJ-181 was grouped into the genus Cohnella, most closely related to Cohnella hashimotonis F6_2S_P_1 (98.85%) and C.

The members of a widespread Aspergillus fungi genus cause various diseases including the invasive aspergillosis with high morbidity and mortality rates, especially for immunosuppressed patients. One of the main carbohydrate structures on the surface of their cell wall is the galactomannan (GM) which is used in diagnostic kits for the detection of specific types of aspergillosis. However, limited specificity of currently available test systems urges the need for their further improvement.
