This plant plays an important role in interacting with trees, sharing microorganisms, and performing specific functions in the process of tree colonization. The objective of this study was to evaluate and compare the microbiomes of T. recurvata collected from two different locations (trees and fences) and two plant tissues (leaves and roots). The hypothesis of this study was that the microbiome of T. recurvata is composed of microorganisms that would provide nutritional support to compensate for the lack of nutrients in a particular growth support. The results showed significant differences in microbial diversity between trees and fences, with trees exhibiting higher richness and more complex microbial networks. Proteobacteria was the most prevalent bacterial phylum, with Actinobacteria and Sphingomonas also playing key roles in nitrogen fixation and plant growth. Fungal communities were similar across locations, with Ascomycota and Basidiomycota being predominant, but Paraconiothyrium and Nigrospora showed significant differences in abundance between trees and fences. Functional analysis indicated similar metabolic profiles across leaf and root samples, with key functions for T. recurvata including carbohydrate and amino acid metabolism, stress control, and biofertilization." 2024-10-16T00:00:00Z https://luck.synhera.be/handle/123456789/3120 Growth promotion and modulation of the soybean microbiome INTACTA RR PRO with the application of the fungi Trichoderma harzianum and Purpureocillum lilacinum Rigobelo, Everlon Cid; de Carvalho, Lucas Amoroso Lopes; Santos, Carlos Henrique Barbosa; Frezarin, Edvan Teciano; Pinheiro, Daniel Guariz; Nicodemo, Daniel; Babalola, Olubukola Oluranti; DESOIGNIES, Nicolas Abstract : "Soybean is an economically important crop for animal and human nutrition. Currently, there is a lack of information on the effects of Trichoderma harzianum and Purpureocillum lilacinum on INTACTA RR PRO transgenic soybean plants. The present study evaluated the application of T. harzianum and P. lilacinum under field conditions. The results revealed a significant increase in soybean yield at 423 kg ha−1 in response to the application of P. lilacinum compared with the control treatment. In addition, the application of P. lilacinum promoted a significant increase in phosphorus levels in the plant leaves, and there were significant correlations between the increase in taxon abundance for the genus Erwinia and productivity and the average phosphorus and nitrogen content for the plant leaves, for the taxon Bacillus and nitrogen content and productivity, and for the taxon Sphingomonas and nitrogen content. The Bradyrhizobium taxon was identified in the P. lilacinum treatment as a taxon linking two different networks of taxa and is an important taxon in the microbiota. The results show that the application of the fungus P. lilacinum can increase the productivity of soybean INTACTA RR PRO and that this increase in productivity may be a function of the modulation of the microbiota composition of the plant leaves by the P. lilacinum effect." 2024-09-09T00:00:00Z https://luck.synhera.be/handle/123456789/3119 Effects of Trichoderma harzianum and Bacillus subtilis on the root and soil microbiomes of the soybean plant INTACTA RR2 PRO™ Rigobelo, Everlon Cid; de Andrade, Luana Alves; Santos, Carlos Henrique Barbosa; Frezarin, Edvan Teciano; Sales, Luziane Ramos; de Carvalho, Lucas Amoroso Lopes; Pinheiro, Daniel Guariz; Nicodemo, Daniel; Babalola, Olubukola Oluranti; Verdi, Maria Caroline Quecine; Mondin, Mateus; DESOIGNIES, Nicolas "This study aimed to evaluate the effects of these microorganisms on this soybean cultivar by analyzing parameters, such as root and shoot dry matter, nutritional status, and root and soil microbial diversity." - Extrait de l'abstract 2024-08-27T00:00:00Z https://luck.synhera.be/handle/123456789/3118 Purpureocillium lilacinum as an Agent of Nematode Control and Plant Growth-Promoting Fungi Rigobelo, Everlon Cid; Nicodemo, Daniel; Babalola, Olubukola Oluranti; DESOIGNIES, Nicolas Abstract : "Plants support numerous microorganisms within their tissues and the rhizosphere, and these microorganisms, known as the microbiota, can influence plant growth and health. Up to 40% of a plant’s photosynthetic metabolism may be invested in the rhizosphere. The microbiota is considered an extra genomethat canbemodulatedtomeetplantneeds. Researchers have identified a set of genes from these microorganisms, known as the microbiome, which can be manipulated to enhance plant growth and health, improve nutrient absorption, reduce the need for chemical fertilizers, increase resistance to pathogens and pests, and increase stress tolerance. In particular, fungi exhibit large genetic and metabolic diversity and are often used to promote plant growth. For example, the fungus Purpureocillium lilacinum has been employed primarily as a biocontrol agent to manage nematodes, but some studies have suggested that it may also promote plant growth by increasing the efficiency of the plant in absorbing nutrients from the soil and providing phytohormones to plants. Therefore, the current review aims to summarize the existing literature on the use of this fungus in agriculture as nematodes control, and discuss its potential as a plant growth-promoter." 2024-06-05T00:00:00Z
