Host Specificity of Endophytic Fungi from Stem Tissue of Nature Farming Tomato (Solanum lycopersicum Mill.) in Japan

et al. 2020

To understand the distribution of the cultivable fungal community in plant tissues from nature farming tomato plants, we sampled plants of seven different tomato cultivars and recovered 1742 fungal isolates from 1895 stem tissues sampled from three sites in Japan. Overall, the isolation frequency was low (3–13%) and the isolation and colonization frequencies did not vary significantly as a function of the cultivar. The fungi were divided into 29 unique operational taxonomic units (OTUs) with 97% ITS gene sequence identity, the majority of which belong to Ascomycota (99.3%). The dominant genera of cultivable endophytic fungi were Fusarium (45.1%), Alternaria (12.8%), Gibberella (12.0%), and Dipodascus (6.8%). The alpha diversity of the fungal endophytes varied among tomato cultivars. Ordination analysis performed to investigate patterns of endophyte community assemblages on the various cultivars revealed that host cultivars had a significant impact on the endophyte community assemblages in all the study sites. Some of the taxa Fusarium, Alternaria, and Penicillium were found on all cultivars, while few were uniquely present in different cultivars. The dominant taxa may be adapted to the particular microecological and physiological conditions present in tomato stems.

“…Marine microorganisms have taken the limelight as a producer of active natural products, including anti-bacterial, anti-fungal, anti-viral, enzyme, anti-biofilm, anti-cancer, anti-oxidant, and anti-inflammation substances [ 4 ]. Due to co-existing with their host and the possible production of compounds with novel structures and diverse activities, marine microorganisms associated with marine animals and plants have attracted much attention [ 5 , 6 ].…”

“…Marine algae have attracted attention as a source of new bioactive molecules of biomedical interest, and they provide suitable living conditions and abundant nutrition for different microorganisms, while in return, microorganisms may provide protection and ultimately survival value to their hosts by producing bioactive molecules, or by affecting the growth and evolution process via the signal transduction pathway [ 5 , 6 , 7 , 8 , 9 ]. Although algae-associated microorganisms have great potential for secondary metabolite synthesis, some related studies deserve more attention [ 10 , 11 ].…”

Marine natural products have been recognized as the most promising source of bioactive substances for drug discovery research. This review illustrates the diversity of culturable actinobacteria associated with marine algae, their bioactivity and metabolites, and approaches to their isolation and determination of their biological properties. Furthermore, actinobacteria associated with marine algae are presented as a new subject for an extensive investigation to find novel and active natural products, which make them a potentially rich and innovative source for new drug development deserving more attention and exploration.

“…Research involving enzymes has intensified and this is due to their recognized catalytic capacity, which is applied in the optimization of industrial processes. Enzymes are active and versatile, and perform reactions quickly, especially under mild reaction conditions (Sharma et al, 2020). Hydrolases and oxyredutases are the classes of enzymes that have the greatest potential in various industries such as those of food, textile, cellulose, in addition to use in effluent treatment (Naik et al, 2019).…”

This work evaluates the enzymatic production of hydrolases and oxireductases by endophytic fungi isolated from leaves of the caesarweed (Urena lobata L.), which is a perennial plant that is well adapted to the Amazon floodplains region, being and is widely used in the production of hessian sacks and other products of natural fiber. Fungi strains Fusarium sp. (1290) and Corynespora sp. (1291) were reactivated, and had their DNA extracted and sequenced to obtain molecular identification. For enzymatic production, dried and ground caesarweed was used as a substrate in the mineral salt solutions Manachini and GLBN 40 over during 10 days of submerged cultivation (CS) under agitation. The CA was vacuum filtered daily with a 0.22 µm Millipore membrane to obtain enzymatic extracts, from which the activities of FPase, xylanase, CMCase, β-glycosidase, pectinase, laccase, manganese peroxidase (MnP) and lignin peroxidase (LiP) were evaluated. Lines strains 1290 and 1291 were identified as F. pseudocircinatum and C. torulosa, respectively, the latter being the best producer of laccase (8,691 U/L), MnP (5,353 U/L), β-glycosidase (0.328 U/mL) and CMCase (0.351 U/mL) and the fungus F. pseudocircinatum was the best producer of FPase (1.294 U/mL), xylanase (12.052 U/mL) and pectinase (0.183 U/mL). No LiP activity was detected for either of the strains. The results showed that the strains used are promising for the production of seven of the eight quantified enzymes, and these enzymes are of interest to several industrial sectors.
