Summary
This summary is machine-generated.Root endophytic fungus Serendipita indica enhances drought tolerance in Pinus taeda seedlings by altering metabolome and proteome. Inoculation significantly increases key metabolites and specific proteins, improving seedling resilience to water stress.
Area Of Science
- Plant Biology
- Microbiology
- Biochemistry
Background
- Pinus taeda is vital for forestry, but susceptible to drought in southern China.
- Understanding drought tolerance mechanisms and beneficial microbes is crucial for P. taeda cultivation.
Purpose Of The Study
- To investigate the impact of Serendipita indica inoculation on Pinus taeda drought tolerance.
- To analyze metabolomic and proteomic changes in P. taeda needles under drought stress with and without S. indica.
Main Methods
- Pinus taeda seedlings were inoculated with Serendipita indica and subjected to 53 days of drought stress.
- Metabolome and proteome analyses of seedling needles were performed.
- KEGG pathway analysis was used to identify enriched metabolic pathways.
Main Results
- S. indica inoculation significantly altered needle metabolome, upregulating flavonoids and organic acids like eriocitrin and citric acid under drought.
- Proteome analysis revealed specific proteins (H9X056, H9VDW5, H9VNE7) and increased abundance of water-deficit-inducible proteins and ribosomal proteins in inoculated seedlings.
- Inoculation modulated pathways including phenylpropanoid biosynthesis and cutin, suberine and wax biosynthesis under drought stress.
Conclusions
- Serendipita indica inoculation enhances Pinus taeda drought tolerance through significant metabolomic and proteomic reprogramming.
- The study identifies key metabolites and proteins involved in drought stress response, providing a basis for further functional studies.
- Findings offer insights into utilizing beneficial microorganisms to improve forest resilience in drought-prone regions.

Water plays a significant role in the life cycle of plants. However, insufficient or excess of water can be detrimental and pose a serious threat to plants.
Under normal conditions, water taken up by the plant evaporates from leaves and other parts in a process called transpiration. In times of drought stress, water that evaporates by transpiration far exceeds the water absorbed from the soil, causing plants to wilt. The general plant response to drought stress is the synthesis of hormone...
Plants often form mutualistic relationships with soil-dwelling fungi or bacteria to enhance their roots’ nutrient uptake ability. Root-colonizing fungi (e.g., mycorrhizae) increase a plant’s root surface area, which promotes nutrient absorption. While root-colonizing, nitrogen-fixing bacteria (e.g., rhizobia) convert atmospheric nitrogen (N2) into ammonia (NH3), making nitrogen available to plants for various biological functions. For example, nitrogen is essential for the...
Plants have the impressive ability to create their own food through photosynthesis. However, plants often require assistance from organisms in the soil to acquire the nutrients they need to function correctly. Both bacteria and fungi have evolved symbiotic relationships with plants that help the species to thrive in a wide variety of environments.
The collective bacteria residing in and around plant roots are termed the rhizosphere. These soil-dwelling bacterial species are incredibly diverse....
Salt stress—which can be triggered by high salt concentrations in a plant’s environment—can significantly affect plant growth and crop production by influencing photosynthesis and the absorption of water and nutrients.
Plant cell cytoplasm has a high solute concentration, which causes water to flow from the soil into the plant due to osmosis. However, excess salt in the surrounding soil increases the soil solute concentration, reducing the plant’s ability to take up...
