Studies were carried out on B-group vitamins production by mycorrhizal fungi grown in vitro at different pH values. It was found that not all the fungi investigated produced all the B-group vitamins studied. Production of the vitamins varied between species and was influenced by the pH of the medium. Out of seven fungal species studied three did not produce biotin. Suillus bovinus synthesized this vitamin both in the acidic and neutral medium. Thiamin was produced by the fungi in minute amounts…

Allelopathic effects of artemisinin on ectomycorrhizal fungi
TLDR
It is suggested that artemisinin could alter the growth and nutrient uptake of ECMFs in forest soils, which could potentially risk changes in the distribution, performance and biodiversity of ECmFs in Forest ecosystems.

TLDR
The role of cyanobacteria in triggering the growth and development of plants and hence its utilization in agriculture is reviewed.
Yeasts Bioproducts Prospection from Different Brazilian Biomes
This study reports the bioprospection of yeasts from different biomes in the State of São Paulo aiming the biotechnological production of enzymes and vitamins. A total of 427 yeasts were isolated
Effects of thiamine and nitrogen fertilizer form on the number of N2−fixing and total bacteria in the rhizosphere of maize plants
The effects of thiamine (vitamin B1) application as seed dressing and of N form supplied (NH4+ versus NO3−) on rhizosphere pH and on rhizosphere microorganisms were evaluated in two different soils.

Production of B-group vitamins by mycorrhizal fungi and actinomycetes isolated from the root zone of pine (Pinus sylvestris L.)
TLDR
The vitamin produced in largest amounts by the mycorrhizal fungi was thiamin, and more actinomycetes isolated from the rhizosphere than from the root free soil produced B-group vitamins.
Suppression and stimulation of mycelial growth of Phytophthora cryptogea by certain thiamine-requiring and thiamine-synthesizing bacteria.
TLDR
Preculturing a synthetic medium with bacteria of the genus Arthrobacter reduced growth of Phytophthora cryptogea and there was some evidence that these bacteria also removed other fungal nutrients from the medium.
GROWTH VARIATION BETWEEN AND WITHIN SPECIES OF ECTOMYCORRHIZAL FUNGI IN RESPONSE TO pH IN VITRO
TLDR
Isolates that grew best in vitro at high pH levels did not originate from high pH soils, and isolates that grow well over a broad pH range would be preferred for inoculation in tree nurseries.
Plant root excretions in relation to the rhizosphere effect
SummaryThe root exudates from seedlings of ten plant species grown under conditions of controlled environment and nutrition were biassayed for six vitamins of the B-group. Biotin was consistently
B-Vitamins in root exudates of cotton
TLDR
Thiamine, biotin, pyridoxine, andp-aminobenzoic acid were found in higher amounts in the exudates of diploid cotton strains, especially K 2 and 6186 in KPT soil.
Selection of Fungi for Ectomycorrhizal Inoculation in Nurseries
TLDR
In co-evolving with their host plants, the mycorrhizal fungi have developed impressive physiological and ecological diversity.
Plant root excretions in relation to the rhizosphere effect
SummaryThe excretory products of roots of peas and oats grown aseptically in quartz sand were studied by paper chromatography. Peas were found to excrete considerable amounts of amino material during
Excretion of Thiamin and Biotin by the Roots of Higher Plants
TLDR
This work has suggested the possibility that excretion of minute amounts of bacterial growth factors by the growing plant might be a fundamental factor in determining the character of the rhizosphere microflora.
