Omics approaches revealed how arbuscular mycorrhizal symbiosis enhances yield and resistance to leaf pathogen in wheat

Scientific Reports, Journal Year: 2018, Volume and Issue: 8(1)

Published: June 19, 2018

Besides improved mineral nutrition, plants colonised by arbuscular mycorrhizal (AM) fungi often display increased biomass and higher tolerance to biotic abiotic stresses. Notwithstanding the global importance of wheat as an agricultural crop, its response AM symbiosis has been poorly investigated. We focused on role fungus nutrition wheat, potential protective effect against Xanthomonas translucens. To address these issues, phenotypical, molecular metabolomic approaches were combined. Morphological observations highlighted that displayed grain yield, well a reduction in lesion area following pathogen infection. elucidate mechanisms underlying phenotype, we investigated changes transcripts proteins roots leaves during double (wheat-AM fungus) tripartite fungus-pathogen) interaction. Transcriptomic proteomic profiling identified main pathways involved enhancing plant biomass, promoting bio-protective leaf pathogen. Mineral amino acid contents roots, seeds, protein oxidation profiles leaves, supported omics data, providing new insight into exerted confer stronger productivity enhanced resistance X. translucens wheat.

The worldwide use of plant biostimulants (PBs) represents an environmentally friendly tool to increase crop yield and productivity. PBs include different substances, compounds, growth-promoting microorganism formulations, such as those derived from arbuscular mycorrhizal fungi (AMF) or seaweed extracts (SEs), which are used regulate enhance physiological processes in plants. This study analyzed the physiological, ecological, biochemical implications addition two PBs, AMF SE (both alone combination), on tomato plants (Solanum lycopersicum L. cv.

Plants defend themselves against ecological stresses including drought. Therefore, they adopt various strategies to cope with stress, such as seepage and drought tolerance mechanisms, which allow plant development under conditions. There is evidence that microbes play a role in tolerance. In this study, we presented review of the literature describing initiation mediated by inoculation fungi, bacteria, viruses, several bacterial elements, well transduction pathways identified via archetypal functional or morphological annotations contemporary “omics” technologies. Overall, microbial associations potential mediating protection responses drought, an important factor for agricultural manufacturing systems are affected fluctuating climate.

The arbuscular mycorrhizal fungus Rhizophagus clarus improves physiological tolerance to drought stress in soybean plants

Scientific Reports, Journal Year: 2022, Volume and Issue: 12(1)

Published: May 31, 2022

Soybean (Glycine max L.) is an economically important crop, and cultivated worldwide, although increasingly long periods of drought have reduced the productivity this plant. Research has shown that inoculation with arbuscular mycorrhizal fungi (AMF) provides a potential alternative strategy for mitigation stress. In present study, we measured physiological morphological performance two soybean cultivars in symbiosis Rhizophagus clarus were subjected to stress (DS). The Anta82 Desafio grown pots inoculated R. clarus. Drought was imposed at V3 development stage maintained 7 days. A control group, well-irrigated plants no AMF, established simultaneously greenhouse. colonization rate, physiological, morphological, nutritional traits recorded days 3 after conditions implemented. cultivar presented highest percentage AMF colonization, N K leaves, whereas DS group had water use efficiency, + thermal dissipation permitted higher values Fv/Fm, A, plant height. results principal components analysis demonstrated both performed similarly under well-watered plants.

However, plant sciences, metabolomics underused, even though studies are relatively easy and cheap when compared to those on humans animals. Despite their importance human nutrition, cereals, especially wheat, remain understudied from point of view. The durum wheat has been essentially neglected, although its genetic structure allows the inference common mechanisms that can be extended other cereal species. This review covers present achievements highlighting connections with species (especially bread wheat).
