Project description:Endophytic fungi in tea leaves Genome sequencing and assembly
| PRJNA688120 | ENA
Project description:<p>Entomopathogenic fungi have the ability to both directly kill insect pests and act as plant endophytic fungi to impact plant growth and development. Despite this, the widespread endophytic use of these fungi in tea plants (Camellia sinensis) is still limited. This study examined how Beauveria bassiana colonizes tea plant tissues and its impact on tea plant growth and development. Through amplicon sequencing and liquid chromatography-tandem mass spectrometry (LC-MS/MS), the study investigated the response patterns of dominant endophytic microbial populations in tea plants during fungal colonization and the alterations in secondary metabolites in tea plants due to the colonization process. B. bassiana effectively colonized tea seedlings through root irrigation and foliar spraying methods, showing a preference for stems, and the colonization persisted for more than 90 days. Colonization resulted in a reduction in the diversity and structural stability of the endophytic microbial community in tea plants; however, it also enhanced the importance of ecologically mutualistic relationships or cooperative interactions in community assembly. Additionally, colonization had a more pronounced effect on endophytic fungi compared to endophytic bacteria. It led to an increase in the relative abundance of arbuscular mycorrhizal fungi in root tissues and a decrease in the relative abundance of total plant pathogens in tea plant tissues. Terpenoids were the most significantly associated differential metabolites following B. bassiana colonization, followed by steroids and their derivatives, and flavonoids. Colonization by B. bassiana resulted in elevated levels of the majority of differential metabolites in tea plant stems at the onset of colonization. The colonization of B. bassiana in tea plants displayed a strong positive correlation with 26 distinct metabolites, such as proanthocyanidin B2 and L-malic acid. This colonization altered the endophytic microbial community, impacting metabolic pathways associated with plant hormone synthesis, volatile compound production, as well as the growth, development, and defense of tea plants.</p>

Project description:The endophytic fungi of certain grasses and herbaceous plants provide anti-herbivore defense compounds, thus living in mutualistic interaction with their hosts. Still, there is little information on such cooperation for tree-associated endophytes. We investigate the influence of the endophytic fungus Cladosporium cladosporioides on the chemical defenses of black poplar Populus nigra trees and the consequences on feeding preference, fitness of herbivorous insects, and insect community assembly. Strikingly, endophyte colonization increases both constitutive- and induced poplar defenses. Generalist Lymantria dispar larvae prefer and perform better on uninfected poplars due to the higher concentrations of salicinoids and fungal alkaloid stachydrine in endophyte-infected leaves. Under field conditions, the endophytic fungus shapes insect community assembly in young black poplar trees. Our results show that endophytic fungi can play a significant role in defending trees against herbivorous insects and structuring insect communities.

Project description:Endophytic fungi are fungi that live inside the roots of plants. They can promote plant growth through a variety of direct and indirect mechanisms. Direct mechanisms include the production of phytohormones, such as auxin and gibberellins, which can stimulate plant growth. Endophytic fungi can also fix nitrogen, solubilize phosphate, and produce siderophores, which are compounds that chelate iron and make it available to plants. In addition, some endophytic fungi produce antimicrobial metabolites that can protect plants from pests and pathogens. Indirect mechanisms include the induction of systemic resistance, which is a plant's ability to defend itself against pests and pathogens. Endophytic fungi can also help plants to tolerate abiotic stresses, such as drought, salinity, and heavy metals. In this study, we used a proteomic approach to identify the proteins that are expressed in rice plants after they are treated with endophytic fungi. We found that the treatment with endophytic fungi resulted in the expression of a number of proteins involved in plant growth, stress response, and defense. These results suggest that endophytic fungi can promote plant growth and improve plant resilience to stress.
