“…Variations in diversity and abundance observed in this study may be associated with the nutritional and defense properties at each developmental stage of these organs (Sanchez-Azofeifa et al, 2012). In this study, the largest differences in endophytic fungal diversity among the plants from Catas Altas (younger) and Santa Bárbara (older) can be attributed to plant age (Table 3).…”

Eucalyptus species are among the most widely grown and most economically valuable trees worldwide. In Brazil, eucalyptus is of major environmental and economic importance because it generates thousands of jobs and offers an alternative to using wood from native forests. In forest ecosystems, plant shoots are considered a common habitat for various microorganisms, and plants of the family Myrtaceae are an important source of fungal biodiversity. However, very little is known about the diversity and microbial distribution in eucalyptus leaves. This study aimed at showing the diversity and distribution of endophytic fungi in the leaves of eucalyptus plants aged 18 and 72 months. The leaves were collected at the onset of the rainy period, during the rainy period, and during the dry period. Diversity was measured using DNA extraction, 18S rRNA subunit amplifi cation, denaturing gradient gel electrophoresis (DGGE), and sequencing of eluted bands. The endophytic fungal community was affected by plant location. Differences observed in the distribution of the phylogenetic groups found in the upper, middle and lower thirds of the tree canopy indicate that the endophytic community distribution in eucalyptus is dependent on leaf position. The age of the plants affected the diversity of endophytic fungi in Eucalyptus "urograndis". Phylogenetic analysis showed that the phyla Basidiomycota and Ascomycota dominate in the environments studied. The description of endophytic fungal diversity in this important forest species is an important step for assessing this genetic resource in the search for metabolites and processes tha t can contribute to improving plant development.

“…Endophytic fungi survive in host plants are influenced by environmental factors such as temperature and humidity, chemicals and leaf anatomic structures. Thus, affects the abundance and diversity of endophytic fungi (Sanchez-Azofeifa, Oki, Fernandes, Ball, & Gamon, 2012). Changes in endophytic fungi communities are related to leaf age (Fernandes, Oki, Sanchez-Azofeifa, Faccion, & Amaro-Arruda, 2011, Hilarino et al, 2011 and even to plant tissue types (Sanchez-Azofeifa, Oki, Fernandes, Ball, & Gamon, 2012).…”

Many biotic and abiotic factors are involved in colonization, including chemical and plant structure (Sanchez-Azofeifa, Oki, Fernandes, Ball, & Gamon, 2012), and environmental conditions where endophytic fungi are present (Fernandes, Oki, Sanchez-Azofeifa, Faccion, & Amaro-Arruda, 2011).…”

Endophytic fungi have roles to protect the plant from herbivorous insects and diseases, and to support the absorption process of nutrients needed by plants for photosynthesis. Related to the important role of endophytic fungi, research was aimed to identify fungal endophytes associated with young, mature and old leaves on apple and to evaluate the effect of leaf ages on the abundance and diversity of endophytic fungi. The research was conducted in Biological Control Laboratory, Department of Plant Pests and Diseases, Faculty of Agriculture, Universitas Brawijaya from May to September 2016. Apple leaves sampling was done diagonally, and taken from nine apple trees. Based on macroscopic and microscopic characteristics, 38 isolates were identified. In the old apple leaves, it obtained 17 isolates that consisted of 5 genera, mature leaves obtained 14 isolates consisted of 6 genera, and young leaves 7 isolates obtained consists of 2 genera. The mature leaves have highest abundance and diversity of endophytic fungi compared to young and old leaves. Endophytic fungi apple leaf dominated by Aspergillus. Mature and young leaves were different from old one based on Bray-Curtis similarity.

Regulation by fungal endophyte of Rhodiola crenulata from enzyme genes to metabolites based on combination of transcriptome and metabolome

BACKGROUNDThe contents of some its crucial metabolites tend to decrease when Rhodiola crenulata is cultured at low altitude. Interestingly, it was found that an endophyte, Phialocephala fortinii, could alleviate this problem.RESULTSThere were 16 151 differential genes including 14 706 up‐regulated and 1445 down‐regulated unigenes with significant differences (P < 0.05), and a total of 1432 metabolites exhibited statistically significant (P < 0.05) metabolic differences comprising 27 different marker metabolites which showed highly significant values of VIP > 5 and P < 0.01. Results highlight differential regulation of 20 enzymatic genes that are involved in the biosynthesis of five different marker metabolites including acetaldehyde, homocysteine, cyclopropylamine, 1‐pyrrolinium and halistanol sulfate.CONCLUSIONSThe positive physiological effect of P. fortinii on R. crenulata encompasses differential regulation in carbohydrate metabolism, lipid metabolism and secondary metabolite synthesis. © 2020 Society of Chemical Industry
