Evaluation of foliar fungal endophyte diversity and colonization of medicinal plant Luehea divaricata (Martius et Zuccarini)

Endophyte microorganisms are organisms that live inside plants without causing any apparent damage to their hosts. Since all plants exhibit endophyte microorganisms, it is believed that mutual association is of great importance in nature. Luehea divaricata (Martius & Zuccarini), known popularly in Brazil as açoita-cavalo, is a big-sized tree with a wide distribution in the country that possesses medicinal qualities for: dysentery, leucorrhea, rheumatism, blennorrhoea, tumors, bronchitis, and depuration. This research aims at isolating and molecularly characterizing fungi isolates from L. divaricata by sequence analysis of ITS1-5.8S-ITS2 rDNA. Further, the colonization of endophyte in the host plant by Light and Scanning Electron Microscopy will also be investigated. Whereas, genera Alternaria, Cochliobolus, Diaporthe, Epicoccum, Guignardia, Phoma, and Phomopsis, were identified; rDNA sequence analysis revealed intra-species variability among endophyte isolates of the genus Phomopsis sp. Light and Scanning Electron Microscopy techniques showed the presence of endophyte fungi inside L. divaricata leaves, inhabiting inter-and intra-cellular spaces. These types of extensive colonization and dissemination were reported throughout all the leaf parts in palisade parenchyma, esclerenchyma, spongy parenchyma, adaxial epidermis, and vascular bundle indicating colonization of endophytes in multiple structural sub-niches in the host plant.

“…In relation to the percentage of the isolates, the data are consonant with other findings showing that Phomopsis is quite frequently found as an endophyte in several plants (Chareprasert et al, 2006;Bernardi-Wenzel et al, 2010).…”

“…Due to the pluviometric and relative humidity characteristics, it is possible that T. elegans was in the best conditions to afford the maximum colonization. Chareprasert et al (2006) stated that ripe leaves show a greater colonization by endophytes. The same was also found by other authors showing that endophytic colonization frequencies tend to increase indicating that rain, humidity and temperature can influence the occurrence of endophytes (Arnold and Herre, 2003;Chareprasert et al, 2006).…”

ABSTRACT. Various types of organisms, mainly fungi and bacteria, live within vegetal organs and tissues, without causing damage to the plant. These microorganisms, which are called endophytes, can be useful for biological control and plant growth promotion; bioactive compounds from these organisms may have medical and pharmaceutical applications. Trichilia elegans (Meliaceae) is a native tree that grows abundantly in several regions of Brazil. Preparations using the leaves, seeds, bark, and roots of many species of the Meliaceae family have been widely used in traditional medicine, and some members of the Trichilia genus are used in Brazilian popular medicine. We assessed the diversity of endophytic fungi from two wild specimens of T. elegans, collected from a forest remnant, by sequencing ITS1-5.8S-ITS2 of rDNA of the isolates. The fungi were isolated and purified; 97 endophytic fungi were found; they were separated into 17 morpho-groups. Of the 97 endophytic fungi, four genera (Phomopsis, Diaporthe, Dothideomycete, and Cordyceps) with 11 morpho-groups were identified. Phomopsis was the most frequent genus among the identified endophytes. Phylogenetic analysis showed two major clades: Sordariomycetes, which includes three genera, Phomopsis, Diaporthe, and Cordyceps, and the clade Dothideomycetes, which was represented by the order Pleosporales.

“…In the current study two sterile forms were isolated. Chareprasert et al (2006) found that Phomopsis was the most frequent endophytic fungus isolated from leaves, both young and adult, of Tectona grandis and Samanea saman Merr. Similarly, in the present study, Phomopsis spp.…”

A total of 616 fungal isolates were obtained from 1600 segments of leaves and stems of the medicinal plant Anisomeles malabarica during four seasons (2009)(2010). Fourteen different morphospecies were isolated: Botryodiplodia theobromae, Colletotrichum dematium, Pestalotiopsis microspora, Phoma betae, Phomopsis arnoldiae, Phomopsis stipata, Phomopsis sp., Phomopsis tersa, Phyllosticta murnadensis, Septoria sp., Penicillium sp., Nigrospora sp. and sterile forms. Phomopsis spp. was the most dominant and frequently isolated taxon. Colonization frequency (%) differed significantly between the seasons. The total colonization frequency of endophytes during south-west monsoon comprised young leaves 6.6%, mature leaves 15.7%, young stems 3.6% and mature stems 13.4%; north-east monsoon comprised young leaves 4.3%, mature leaves 16%, young stems 7% and mature stems 15.9%; winter comprised young leaves 14%, mature leaves 21.7%, young stems 12.5% and mature stems 17.1%; summer comprised young leaves 1.2%, mature leaves 4.4%, young stems 0.9% and mature stems 2.6%. The colonization rate was higher during the winter than in the monsoon and summer seasons. Moreover, the higher colonization frequency was found in mature leaves than in young leaves. The maximum relative percentage occurrence was coelomycetes (97.91%) followed by agnomycetes (1.33%) and hyphomycetes (0.76%).
