The molecular identification of maize dwarf mosaic virus (MDMV) and its effects on the morphophysiological traits of maize (Zea mays L.) was the focus of the presented research, intending to study the activity dynamics of two main types of enzymes, peroxidases, weakly binding to the membrane, and soluble peroxidases. The molecular identification of the virus engaged the use of the RT-PCR method. Results revealed that in the climatic conditions of Uzbekistan, red necrotic spotting, yellow mosaic with a large border on the edge of the leaf, curling of the leaves, yellow striped mosaic, and short stature all appeared in the maize plants. According to previous symptoms, the visual diagnostic methods used determine the maize yellow mosaic virus indications. In the existing study, the gene responsible for the protein coat synthesis (SR) nucleotide sequence served to diagnose the MDMV, and as a result, PCR tests showed yellow streaks on the leaves of maize plants. The mosaic and motility symptoms have been characteristic proofs of MDMV. The MDMV infects the maize plants in the initial growth phase (3–5 leaves), then the symptoms appear after a few days. Through morphological indicators, viral disease identification is possible at subsequent stages (6–7 leaves). Using spectrophotometry, the peroxidase enzyme activity in maize plants receives the virus infection to determine an early level of infectivity. The results confirmed that, in infected maize plants, peroxidase associated with the cell membrane was much more active than in control plants. It proves that contaminated Zea mays plants were in a stressful situation due to the virus. The RT-PCR method, widely used in diagnostics, sought to identify the virus species affiliation. PCR proceeded based on the virus соat protein (CP) gene.

“…Trichoderma spp. tem sido vastamente empregado na agricultura como fungo promotor de crescimento de plantas e biopesticida para controlar doenças transmitidas pelo solo (Abdenaceur, 2022). Resultados positivos também foram encontrados por que, comprovam a eficiência do isolado T. asperellum UFT-201 em incrementar biomassa em gramíneas (arroz e milho) e leguminosas (soja e feijão-caupi).…”

A produção agrícola brasileira é considerada uma das maiores do mundo, devido ao seu tamanho territorial e o seu potencial em produzir grãos. Trichoderma spp. é um dos fungos mais pesquisados no Brasil, pois tem ocorrência natural em praticamente todos os tipos de solos, e por possuir uma versatilidade de ação próprias, podendo atuar como promotor de crescimento vegetal. Diante disso, objetivou-se avaliar a eficiência da inoculação do isolado UFT-201 como promotor de crescimento nas culturas do milho e arroz em casa de vegetação. O experimento foi conduzido na estação experimental da Universidade Federal do Tocantins (UFT) - Campus Universitário de Gurupi. Os tratamentos consistiram em cinco doses do inoculante (0, 3, 6, 9, 12 g kg-1), misturados à semente no momento da semeadura. A cepa utilizada foi obtida no Laboratório de Agromicrobiologia Aplicada e Biotecnologia da Universidade Federal do Tocantins. O inoculante utilizado foi preparado em fermentação sólida utilizando arroz como substrato. Foram avaliadas características morfológicas (altura, volume de raiz, massa seca) e fisiológicas (pigmentos fotossintéticos e trocas gasosas) aos 30 e 45 dias após a semeadura. O fungo Trichoderma asperellum UFT-201 inoculado via semente aumentou o volume radicular e a biomassa das plantas de milho e arroz na dose de 6 g kg-1 de sementes. O ganho em biomassa das culturas está relacionado com alterações fisiológicas nas culturas promovido pela inoculação e doses acima de 12 g kg-1 de sementes podem reduzir o desenvolvimento inicial das culturas, principalmente para arroz.

“…The enzyme complex produced by the Trichoderma fungi consists of chitinases, β-glucanases, cellulases, and proteases, which are involved in hydrolysis [ 43 , 44 ]. According to Abdenaceur et al [ 45 ], the Trichoderma species exhibits varying levels of enzymatic activity, producing amylases, pectinases, lipases, and phosphatases. The role of these fungi has previously been studied [ 46 ].…”

Currently, natural polymer materials with bactericidal properties are extremely popular. Unfortunately, although the biopolymer material itself is biodegradable, its enrichment with bactericidal compounds may affect the efficiency of biodegradation by natural soil microflora. Therefore, the primary objective of this study was to evaluate the utility of fungi belonging to the genus Trichoderma in facilitating the degradation of chitosan film modified with cinnamic acid and ellagic acid in the soil environment. Only two strains (T.07 and T.14) used chitosan films as a source of carbon and nitrogen. However, their respiratory activity decreased with the addition of tested phenolic acids, especially cinnamic acid. Addition of Trichoderma isolates to the soil increased oxygen consumption during the biodegradation process compared with native microorganisms, especially after application of the T.07 and T.14 consortium. Isolates T.07 and T.14 showed high lipolytic (55.78 U/h and 62.21 U/h) and chitinase (43.03 U/h and 41.27 U/h) activities. Chitinase activity after incorporation of the materials into the soil was higher for samples enriched with T.07, T.14 and the consortium. The isolates were classified as Trichoderma sp. and Trichoderma koningii. Considering the outcomes derived from our findings, it is our contention that the application of Trichoderma isolates holds promise for expediting the degradation process of chitosan materials containing bactericidal compounds.
