Identification and characterization of endophytic fungi found in plants from northeast Brazilian mangroves: a review

Research Society and Development (2022)

Lívia Karla Remígio Maia Daniela Ribeiro Alves Silvio Gentil Jacinto Selene Maia de Morais Francisco das Chagas de Oliveira Freire

Mangroves constitute an ecosystem formed by different classes of living organisms. Due to its diversity, it has an ecological and environmental value that human activities can threaten. Endophytic fungi, found inside plant tissues, can produce substances of biotechnological value, such as antibiotics and other active principles with pharmacological properties. Therefore, this narrative review of the literature carried out through the analysis of articles found in different databases, such as: 'CAPES Journal Portal,' 'Web of Science,' 'SciElo,' 'Pubmed,' among others, highlights the importance of identifying, characterizing, and isolating endophytic fungi found in Brazilian mangroves and their relevance to the prospection of substances of high biotechnological value to the society. As well as to assist in understanding the ecological dynamics of mangroves in Brazil.

Monitoring cashew seedlings during interactions with the fungus Lasiodiplodia theobromae using chlorophyll fluorescence imaging

Photosynthetica (2014)

Celli Rodrigues Muniz F. C. O. Freire F. M. P. Viana J. E. Cardoso Carlos Antônio Ferreira de Sousa

The chlorophyll (Chl) fluorescence imaging technique was applied to cashew seedlings inoculated with the fungus Lasiodiplodia theobromae to assess any disturbances in the photosynthetic apparatus of the plants before the onset of visual symptoms. Two-month-old cashew plants were inoculated with mycelium of L. theobromae isolate Lt19 or Lt32. Dark-adapted and light-acclimated whole plants or previously labelled, single, mature leaf from each plant were evaluated weekly for Chl fluorescence parameters. From 21 to 28 days, inoculation with both isolates resulted in the significantly lower maximal photochemical quantum yield of PSII (Fv/Fm) than those for control samples, decreasing from values of 0.78 to 0.62. In contrast, the time response of the measured fluorescence transient curve from dark-acclimated plants increased in both whole plants and single mature leaves in inoculated plants compared with controls. The Fv/Fm images clearly exhibited photosynthetic perturbations 14 days after inoculation before any visual symptoms appeared. Additionally, decays in the effective quantum yield of PSII photochemistry and photochemical quenching coefficient were also observed over time. However, nonphotochemical quenching increased during the evaluation period. We conclude that Fv/Fm images are the effective way of detecting early metabolic perturbations in the photosynthetic apparatus of cashew seedlings caused by gummosis in both whole plants and single leaves and could be potentially employed in larger-scale screening systems.

Arroz e feijão intercalados em lavouras de cafeeiras no Acre

Vitor Hugo de Oliveira I. S. Campos J. E. Cardoso F. de Sales

A utilizacao de culturas de ciclo curto em cafezais novos visa principalmente reduzir seus custos de formacao, garantir um melhor aproveitamento do solo, alem de assegurar ao produtor um retorno do capital investido, antes da primeira colheita. Pratica cultural bastante difundida na agricultura acreana, o cultivo intercalar, no entanto, ainda nao dispoe de suficientes informacoes tecnicas locais que permitam recomenda-la, de modo racional, ao produtor. Em consequencia, o seu emprego tem causado, na maioria dos casos, danos que afetam a producao e produtividade do cafeeiro. Com a finalidade de obter dados para a solucao desse problema, estao sendo conduzidos nos campos experimentais da Fazenda EMBRAPA, km 14 da BR-364, municipio de Rio Branco, experimentos cujo objetivo principal e a racionalizacao dessa pratica, atraves da determinacao da populacao de arroz e feijao que intercalada ao cafeeiro, assegure melhores retornos ao cafeicultor, sem provocar danos a lavoura.
