Molecular identification and phylogenetic analysis of Trichoderma isolates obtained from woody plants of the semi-arid of Northeast Brazil

Soil Fungi Promote Vigor in Seeds From Brazilian Dry Seasonal Forest

“…Michelena-Álvarez & Martínez-Hernández (2021) affirm that the actions of recuperations and wood production in Caatinga area areas are incipient because technologies adapted to the conditions, achievements, and possibilities of the region are lacking in the literature. Nevertheless, Silva et al (2021), the use of environmental management that promotes the symbiosis organism and native plants from the Caatinga biome is poorly studied (DANTAS et al, 2019;DANTAS et al, 2020). In this paper (Table 3), we argued about the interaction between the Trichoderma harzianum strain and important species from the Caatinga biome.…”

“…The T. harzianum IBLF 006 is a strain described in the literature such as a vegetal growth promoter in lettuce (PEREIRA et al, 2019), Jacaranda mimosifolia (FERREIRA et al, 2021 c), and Moringa oleifera (FERREIRA et al, 2020). Oliveira et al (2019), describe that the T. harzianum IBLF 006 strain is resistant to high temperatures and ultraviolet radiation, a factor important to be considered in Caatinga conditions, such as for Silva et al (2021). The results for each of the species studied in this research will be discussed below (Table 3).…”

“…Zhang et al (2021) affirm that this gender is an important symbiotic and endophytic, mainly to ecosystem regulation around the world. Carvalho et al (2021), Michelena-Álvarez & Martínez-Hernández (2021), and Silva et al (2021), describe the importance of this fungi gender in symbiosis with plants from the Caatinga, the Brazilian Dry Seasonal Forest, such as a promoter of resistance to the dry season, biological control of pathogens and vegetal growth promotion. On the other hand, the Caatinga is characterized by severe drought events, average luminosity, and high annual temperatures, being adapted to xerophilic conditions, endemism, and high factor of anthropization, and desertification .…”

Endophytic Trichoderma strains isolated from forest species of the Cerrado-Caatinga ecotone are potential biocontrol agents against crop pathogenic fungi

“…This area comprised a fragment of one hectare within the legal reserve [26]. For the identification of the Trichoderma isolates, the gene regions for the translation elongation factor (tef1) and the second largest RNA polymerase subunit (rpb2) were amplified and sequenced, and the construction of phylogenetic trees was performed by comparing the sequences available in GenBank (National Center for Biotechnology Information, NCBI) [27].…”

“…In this study, we investigated the potential role of endophytic Trichoderma strains isolated from forest tree species of the Cerrado-Caatinga ecotone [26,27] as biological control agents of crop pathogenic fungi. First, we evaluated the interaction between endophytes and pathogens by in vitro antagonism bioassays.…”
