Effect of phosphorus limitation on the microbial community assembly in the common bean (Phaseolus vulgaris L.) rhizosphere. Repositório Alice
CHIARAMONTE, J. B.; ROSSMANN, M.; MENDES, R..
Abstract: The indiscriminate use of inputs in agricultural systems, particularly phosphate, combined with the need of growing food production, is causing the depletion of phosphorus mines around the world. In order to mitigate the environmental impact caused by phosphorus exploration microorganisms can be used to increase the efficiency of phosphorus utilization in crop systems by promoting nutrient solubilization and absorption. It is believed that low phosphorus concentration in soil, enriches specific members of the rhizosphere microbiome related to the availability of this element to the plant. In this study, a factorial experiment was performed considering contrasting cultivars in the uptake efficiency of phosphorus (being IAC-Imperador and DOR-364,...

Identification and in silico characterization of soybean trihelix-GT and bHLH transcription factors involved in stress responses Genet. Mol. Biol.
Osorio,Marina Borges; Bücker-Neto,Lauro; Castilhos,Graciela; Turchetto-Zolet,Andreia Carina; Wiebke-Strohm,Beatriz; Bodanese-Zanettini,Maria Helena; Margis-Pinheiro,Márcia.
Environmental stresses caused by either abiotic or biotic factors greatly affect agriculture. As for soybean [Glycine max (L.) Merril], one of the most important crop species in the world, the situation is not different. In order to deal with these stresses, plants have evolved a variety of sophisticated molecular mechanisms, to which the transcriptional regulation of target-genes by transcription factors is crucial. Even though the involvement of several transcription factor families has been widely reported in stress response, there still is a lot to be uncovered, especially in soybean. Therefore, the objective of this study was to investigate the role of bHLH and trihelix-GT transcription factors in soybean responses to environmental stresses. Gene...

Impact of plant domestication on rhizosphere microbiome assembly and functions. Repositório Alice
PÉREZ-JARAMILLO, J. E.; MENDES, R.; RAAIJMAKERS, J. M..
Abstract: The rhizosphere microbiome is pivotal for plant health and growth, providing defence against pests and diseases, facilitating nutrient acquisition and helping plants to withstand abiotic stresses. Plants can actively recruit members of the soil microbial community for positive feedbacks, but the underlying mechanisms and plant traits that drive microbiome assembly and functions are largely unknown. Domestication of plant species has substantially contributed to human civilization, but also caused a strong decrease in the genetic diversity of modern crop cultivars that may have affected the ability of plants to establish beneficial associations with rhizosphere microbes. Here, we review how plants shape the rhizosphere microbiome and how...

Interações e efeitos fisiológicos de bactérias diazotróficas e fungos micorrízicos arbusculares na mandioca. Repositório Alice
BALOTA, E.L.; LOPES, E.S.; HUNGRIA, M.; DOBEREINER, J..
Visando conhecer as interações entre fungos micorrízicos arbusculares e bactérias diazotróficas na cultura da mandioca (Manihot esculenta Crantz), foram conduzidos vários experimentos para avaliar os efeitos de exsudatos de mandioca e de bactérias nos fungos micorrízicos, e a produção de ácido indolacético (AIA) in vitro pelas bactérias diazotróficas. Os experimentos evidenciaram que as bactérias diazotróficas estimularam a colonização micorrízica de Glomus clarum a partir do 30o dia. Os exsudatos de mandioca e das bactérias não apresentaram efeito na germinação de Gigaspora gigantea, mas influenciaram seu crescimento micelial. A adição de exsudatos de mandioca estimulou o crescimento das bactérias diazotróficas in vitro, evidenciando que podem existir,...

Quantification of the mycorrhizal fungal community associated with a modern wheat cultivar (Triticum aestivum) and with a wheat ancestor. Repositório Alice
ROSSMANN, M.; CHIARAMONTE, J. B.; MENDES, R..
Abstract: Plant breeding is an important instrument to improve crop productivity. However, studies have shown that plant breeding, as well as the use of management practices such as tillage and fertilization, influence the plant root microbiome and also may have caused reduction in the genetic diversity of modern cultivars when compared to their ancestors. As the rhizosphere microbiome can profoundly impact plant growth, nutrition and health, we hypothesized that plant breeding can negatively affect the recruitment of beneficial microbes in the rhizosphere and interactions with their favorable microbial partners. A greenhouse experiment was conducted to assess the composition of the rhizosphere mycorrhizal fungi community in wheat (Triticum aestivum)...

Resistance breeding of common bean shapes the physiology of the rhizosphere microbiome. Repositório Alice
MENDES, L. W.; CHAVES, M. G. de; FONSECA, M. de C.; MENDES, R.; RAAIJMAKERS, J. M.; TSAI, S. M..
Abstract: The taxonomically diverse rhizosphere microbiome contributes to plant nutrition, growth and health, including protection against soil-borne pathogens. We previously showed that breeding for Fusarium-resistance in common bean changed the rhizosphere microbiome composition and functioning. Here, we assessed the impact of Fusarium-resistance breeding in common bean on microbiome physiology. Combined with metatranscriptome data, community-level physiological profiling by Biolog EcoPlate analyses revealed that the rhizosphere microbiome of the Fusarium-resistant accession was distinctly different from that of the Fusarium-susceptible accession, with higher consumption of amino acids and amines, higher metabolism of xylanase and sialidase, and higher...
