No clear data are available on how flavonoids from different chemical groups affect root colonization by arbuscular mycorrhizal fungi (AMF) and whether affecting the presymbiotic growth of AMF also AMF. In present work, we compared effect flavones (chrysin luteolin) flavonols (kaempferol, morin, isorhamnetin, rutin) (number entry points degree colonization) tomato plants (Lycopersicum esculentum L.) with these AMF, which has been reported in a recent study. With all tested (Gigaspora rosea,...
Drought greatly affects the growth and development of plants. This stressful condition can trigger an increase in reactive oxygen species (ROS) production that, turn, induce cellular, anatomical, morphological changes that improve drought tolerance. A strain arbuscular mycorrhizal fungi (AMF) is considered efficient when it colonizes roots quickly extensively, absorbs transfers nutrients to plant host, promotes soil aggregation, protects host against disease. We evaluated effect inoculation...
The capacity of roots to sense soil physicochemical parameters plays an essential role in maintaining plant nutritional and developmental functions under abiotic stress. These conditions generate reactive oxygen species (ROS) tissues causing oxidation proteins lipids among others. Some plants have developed adaptive mechanisms counteract such adverse as symbiotic association with arbuscular mycorrhizal fungi (AMF). AMF enhance growth improve transplant survival by protecting host against...
The aim of this study was to assess the effects agronomic practices on arbuscular mycorrhizal (AM) fungal community in soils from Pampa Ondulada region (Argentina), and compare conclusions reached when using pyrosequencing or a morphological approach. AM diversity 3 agricultural exploitations located (Argentina) assessed by 454 amplicon (based spore traits) approaches. Two kinds soil managements are found these sites: non-agronomic. A total 188 molecular operational taxonomic units 29...
The commercial use of genetically modified (GM) plants has significantly increased worldwide. interactions between GM and arbuscular mycorrhizal (AM) fungi are considerable importance given the agricultural ecological role AM lack knowledge regarding potential effects drought-tolerant corn ( L.) on fungal symbiosis. This work studied colonization in five lines growing under two different irrigation regimes (30 100% soil field capacity [SFC]). Four were corn, these drought tolerant....
The growth dynamics of extraradical mycelium and spore formation 14 "Rhizophagus" isolates from different sites in Argentina were evaluated under monoxenic conditions. A modified Gompertz model was used to characterize the development spores for each isolate same lag time, maximal rate total quantity both hyphae determined. Wide variability among detected, all parameters significantly altered by fungal isolate. Discriminant analysis differentiated primarily based on extent produced, yet such...
The Riachuelo river basin (RRB) is considered one of the most polluted environments in world. Knowledge arbuscular mycorrhizal fungi (AMF) adapted to this extremely environment important for establishment future soil restoration projects. This work aims make a first list AMF species present on RRB. Soil and root samples were randomly taken an area approximately 1500 m2, mycorrhization percentages evaluated. detected by molecular morphological techniques. Sixteen 64 reported work. Dominikia...
Abstract Loss of biodiversity and accumulation contaminants in urban soils water bodies cause serious issues metropolitan areas. The Matanza‐Riachuelo river basin (metropolitan area Buenos Aires, Argentina) is one the most environmentally degraded regions world. Senecio bonariensis Hook & Arn (Asteraceae) grows periodically flooded this wetland. This plant concentrates potentially toxic trace elements (PTEs) its tissues establishes symbiosis with arbuscular mycorrhizal (AM) fungi that...
Arbuscular mycorrhizal fungi (AMF) establish an obligate mutualistic symbiosis with many plant species, increasing the uptake of phosphorous and other low-mobile nutrients by roots. In addition, AMF improve biotic abiotic stress tolerance host plants. Under these conditions, reactive oxygen species (ROS) increase occasional damage to proteins, lipids DNA. Antioxidative enzymes in plants can play important role detoxifying ROS, thereby alleviating oxidative stress. nursery practices, are...
