“…The database search protocol yielded a total of 66 studies [PubMed (19), Scopus (4), Scielo (3), Science Direct (25), Web of Science (0), Lilacs (0), Embase (3), search in citations (n = 12)], of which 19 were excluded because they were duplicates and one because it did not meet the eligibility criteria. Forty-six articles were included in the paired analysis of titles, of which 17 studies were selected on abstract reading and included in the review (Figure 1).…”

“…[50] On the other hand, there is a trend towards an increase in the diversity of endophytic fungi isolated from cacti, as some studies have identified fungal species never before described as endophytes of cacti. [5,19,31] The microbial communities present in cacti still require studies to understand their ecology and biodiversity. This perspective is highlighted by studies describing new species, genera, families and orders.…”

“…[37] The isolation of these endophytes showed that cladodes, spines, and roots of cacti are promising niches for the description of new taxa, especially species of the genus Xylaria, which are only found on spines of M. ernestii. [19] Fungi of the genus Xylaria are known to be ligninolytic, causing soft rot type decomposition of wood and leaf litter. [51] This genus has also shown promising potential for the production of enzymes (Meshram et al 2017) and bioactive secondary metabolites with broad-spectrum antimicrobial activities.…”

“…[6,17] Endophytic fungi are a group of polyphyletic organisms that can colonise plant tissues (e. g. stems, flowers, leaves, fruits, roots) for part or all of their life cycle without causing apparent damage to their hosts. [18][19][20] Every plant studied so far shows associations with endophytic microorganisms that provide protection against predators, pathogens and biotic or abiotic stresses. Endophytes also promote growth of plant organs, phytohormone production and nutrient acquisition.…”

“…[25,[31][32][33][34][35] Over the years, fungi that had never been found as endophytes of cacti were described for the first time and new taxa were identified. [5,9,19,[35][36][37] The production of extracellular enzymes and secondary metabolites by endophytic fungi colonising cacti is poorly explored; however, eight studies characterising enzymes and bioactive metabolites produced by endophytes suggest a biotechnological potential. [5,7,9,25,26,[38][39][40] The diversity of endophytic fungi and their promising biotechnological applications, including the record of new taxa associated with Cactaceae, motivated this systematic review.…”

Endophytic fungi are associated with plant health and represent a remarkable source of potential of enzymes and bioactive compounds, but the diversity of endophytes remains uncertain and poorly explored, especially in Cactaceae, one of the most species‐rich families adapted to growing in arid and semi‐arid regions. The aim of this study was to conduct a systematic review on the diversity and bioprospecting of endophytic fungi from Cactaceae. We analysed peer‐reviewed articles from seven databases using PRISMA guidelines. The results showed that the Cactaceae family is a source of new taxa, but the diversity of endophytic fungi of Cactaceae is little explored, mainly the diversity among tissues and by metagenomics. Bioprospecting studies have shown that these microorganisms can be used in the production of enzymes and larvicidal and antifungal compounds. Our results are relevant as a starting point for researchers to develop studies that expand the knowledge of plant mycobiota in arid and semi‐arid ecosystems, as well as comprising a remarkable source of fungal compounds with several biotechnological applications.

Plant tissues harbor abundant endophytes, which are crucial for plant growth. Endophytes present in Alsophila spinulosa, which is enriched with medicinal components, have not been isolated and characterized yet. Here we employed meta-amplicon sequencing to identify endophytic species and examined their diversity in the leaves, petioles, roots and stems of A. spinulosa. Our findings revealed 1,247 operational taxonomic units (OTUs) for endophytic bacteria across 210 species and 476 OTUs for endophytic fungi across 222 species. Alpha diversity analysis showed the highest endophytic bacterial diversity in A. spinulosa roots, whereas fungal diversity was similar across the leaf, petiole and root tissues. Fungal diversity in the leaves and petioles was markedly higher than that in the stems. Furthermore, beta diversity analysis revealed similarities in the endophytic bacterial and fungal compositions between the leaves and petioles, whereas the compositions in roots and stems considerably differed from those in the leaves and petioles. At the genus level, the predominant endophytic bacteria were Methylobacterium-Methylorubrum and Pseudomonas, whereas the predominant endophytic fungi were Cutaneotrichosporon and Pseudofabraea. Linear discriminant analysis effect size revealed characteristic endophytic bacterial genera specific to each tissue type and characteristic endophytic fungal genera specifically in the leaves, petioles and roots. The co-occurrence network analysis indicated that the complexity of endophyte networks was the highest in the leaves and the lowest in the stems of A. spinulosa. Overall, this study elucidates the distribution patterns of endophytes in A. spinulosa across various tissues, offering valuable microbial resources for the development of natural products for medicinal application.
