Distribution of the endophytic fungi community in leaves of Bauhinia brevipes (Fabaceae)

Abstract

ABSTRACT(Distribution of the endophytic fungi community in leaves of Bauhinia brevipes (Fabaceae)). Endophytic fungi represent large, yet unexplored components of biodiversity. Th is work evaluated the richness and the distribution of endophytes in the leaves of Bauhinia brevipes (Fabaceae). A total of 1110 colonies were recovered from the samples and grouped by their morphological traits into 126 taxa. Th e total number of taxa according to leaf development was: 102 in mature leaves, 93 in recently expanded leaves and 79 for unfolded leaves. Th e major endophyte genera were Phomopsis, followed by Dothiorella, Pestalotiopsis and Acremonium. Th e richness and the isolate numbers of endophytes were not statistically aff ected by leaf region. However, some taxa were leaf-age specifi c; six were isolated only from unfolded leaves, nine from recently expanded leaves and 17 were exclusively found in mature leaves. Th e composition of endophytes varied with leaf region; the similarities (Jaccard's Index) among the leaf regions of diff erent leaf ages ranged from 0.36 to 0.46, indicating a high spatial variation in the community of endophytic fungi inside the leaves. Th e high richness of endophytes in this host plant highlights a signifi cant contribution of fungi to tropical biodiversity and the need for further research in this area.

Antibacterial activity of endophytic fungi isolated from Croton lechleri (Euphorbiaceae)

“…Other studies showed leaves with the highest colonization of endophytic fungi (Souza et al, 2004). Similar to the results obtained in this study, Phomopsis and Pestalotiopsis were also one of the most frequent genera isolated as endophytic (Hilarino et al, 2011;Ferreira et al, 2015). Some fungal genera exhibited specificity in relation to the culture medium of isolation.…”

“…The presence of endophytic microorganisms in medicinal plants has been observed in many species (Hilarino et al, 2011;Premalatha and Kalra, 2013;Bezerra et al, 2015). These organisms are often involved in complex relationships between the synthesis, degradation, and accumulation of secondary metabolites of biotechnological interest (Müller et al, 2016).…”

Distribution of the Endophytic Fungi in Apple Leaves

“…Results of photosynthesis used for plant growth and development but it is also used endophytic fungi to survive in the plant tissue.Thus, the leaves have a higher chlorophyll content is characterized by dark green color, the number and types of endophytic fungi on the leaves higher. Hilarino et al (2011) in his study claimed that differences in the composition of endophytic fungi on the leaves of Bauhinia brevipes influenced by the age of the leaf. The leaves are aging tend to receive more nutrients, so the old leaves to get more chlorophyll, leaf color more green old age.…”

“…Endophytic fungi are microorganisms that are in the plant tissue during certain periods of their life cycle, without causing damage to the plants (Hilarino et al, 2011). It play an important role in balancing ecosystems and benefiting the host such as increasing plant growth (Zheng et al, 2017).…”

“…Hilarino et al (2011) claimed that differences in the composition of endophytic fungi on the leaves of Bauhinia brevipes influenced by the age of the leaf. Endophytic fungi colonization is higher in the leaves of certain associated with anatomical structures and susceptibility to infection, changes in biochemical influences (Fernandes, Oki, Sanchez-Azofeifa, Faccion, & Amaro-Arruda, 2011) and leaf nutrient content such as chlorophyll.…”
