The Role of Phialocephala fortinii in Improving Plants’ Phosphorus Nutrition: New Puzzle Pieces

Journal of Fungi, Год журнала: 2022, Номер 8(11), С. 1225 - 1225

Plants' mineral nutrition in acidic soils can be facilitated by phosphate solubilizing fungi inhabiting the root systems of these plants. We attempt to find dark septate endophyte (DSE) isolates roots wild-heather plants, which are capable improving plants' phosphorus levels. Bright-field and confocal laser scanning microscopy were used for visualization endophytes. A model system co-cultivation with Vaccinium macrocarpon Ait. was study a fungal isolate's ability supply plants phosphorus. Fungal phytase activity content estimated spectrophotometrically. In V. vitis-idaea L. roots, we obtained Phialocephala fortinii Wang, Wilcox DSE2 isolate acid (maximum 6.91 ± 0.17 U on 21st day cultivation potato-dextrose broth medium) accumulate polyphosphates hyphae cells. The increase both accumulation biomass is also shown. data same isolate, as puzzle pieces put together, indicate possible mediation P. process intake from inorganic soil reserves

Pseudomonas sivasensis 2RO45 inoculation alters the taxonomic structure and functioning of the canola rhizosphere microbial community

Frontiers in Microbiology, Год журнала: 2023, Номер 14

Inoculation with plant growth-promoting rhizobacteria (PGPR) is an eco-friendly sustainable strategy for improving crop productivity in diverse environments under different conditions. Our earlier study demonstrated that Pseudomonas sivasensis 2RO45 significantly stimulated canola (Brassica napus L. var. napus) growth. The aim of the present was to investigate structural and functional dynamics rhizosphere microbiome after inoculation PGPR P. 2RO45. results based on alpha diversity metrics showed did not alter native soil microbiota. However, introduced strain modified taxonomic structure microbial communities, increasing abundance beneficial microorganisms, e.g., bacteria affiliated families Comamonadaceae, Vicinamibacteraceae, genus Streptomyces, fungi assigned Nectriaceae, Didymellaceae, Exophiala, Cyphellophora vermispora, Mortierella minutissima. analysis community level physiological profiling (CLPP) revealed communities treated rhizospheres were more metabolically active than those non-treated rhizosphere. Four carbon sources (phenols, polymers, carboxylic acids, amino acids) better metabolized by from plants inoculated non-inoculated rhizospheres. Based community-level profiles, altered inoculation. Substrate utilization Shannon (H) index evenness (E) increased plants. provides new insight into PGPR-canola interactions agriculture development.

Structure and Diversity of Endophytic Bacteria in Maize Seeds and Germinating Roots

Microorganisms, Год журнала: 2024, Номер 12(7), С. 1348 - 1348

Seed endophytes in maize, which facilitate the transmission of microorganisms from one plant generation to next, may play a crucial role protection and growth promotion. This study aimed investigate effects various maize varieties on communities endophytic bacteria seeds germinating roots. utilized Illumina high-throughput sequencing technology examine structural diversity differences bacterial within seed (BY1507), silage (QQ446), wild (Teosinte) both The results showed that 416 genera were detected, with Pantoea, Lachnospiraceae, Pararhizobium, Enterobacteriaceae, Stenotrophomonas, Pseudonocardia being most prevalent (relative abundance > 10%) at genus level. No significant difference was observed indices (Chao1, ACE, Shannon, Simpson) among BY1507, QQ446, Teosinte. Shannon Simpson for root endophyte variety significantly higher than domesticated (BY1507 QQ446). PCoA revealed notable overlap Yet, clustering patterns found. Co-occurrence network analysis Teosinte share proportion shared (>30%) between investigation elucidates characteristics microbial roots offering data future research physiological ecological adaptation these communities.
