Epichloë exudates promote in vitro and in vivo arbuscular mycorrhizal fungi development and plant growth
Background and aims: We studied, through exudates employment, the effect of Epichloë (endophytic fungi), both independently and in association with Bromus auleticus (grass), on arbuscular mycorrhizal fungi (AMF) colonization, ...
Motility and biofilm production involved in the interaction of phosphate solubilizing endophytic strains with peanut, maize and soybean plants
(Elsevier B.V., 2020-09)
Endophytic plant growth promoting bacteria are of great interest since the ability to colonize the internal tissues of plants gives it an adaptive advantage. To confer any beneficial effect on the plant, bacteria must ...
No evidence for root-mediated allelopathy in Centaurea solstitialis, a species in a commonly allelopathic genus
Phytotoxicity bioassays and pot experiments using activated carbon both suggest that Centaurea solstitialis (yellow star-thistle) does not rely on phytotoxic root exudates for invasion of California grasslands. Pot experiments ...
Exudation of organic acid anions by tropical grasses in response to low phosphorus availability
(Nature Research, 2020-10-12)
It has been suggested that some tropical grasses can acquire phosphorus (P) from hematite and gypsite by exuding organic acid anions (OAs). However, it remains to be determined exactly which OAs could be involved in each ...
Root exudation of oxalic acid in Lotus corniculatus in response to aluminum toxicity
(Brazilian Journal of Animal Science, 2022)
Effects of P limitation and molecules from peanut root exudates on pqqE gene expression and pqq promoter activity in the phosphate-solubilizing strain Serratia sp. S119
(Elsevier Science, 2017-07)
The mineral phosphate-solubilizing phenotype in bacteria is attributed predominantly to secretion of gluconic acid produced by oxidation of glucose by the glucose dehydrogenase enzyme and its cofactor, pyrroloquinoline ...
