“…Another interesting feature of these phyla is the presence of several secondary metaboliterelated genes, namely giant genes (> 5 kb) (Faria et al, 2018) that may encode structural proteins like non-ribosomal peptide synthetase (NRPS) or polyketide synthase (PKS) and that had shown the ability to produce a wide range of bioactive compounds with antifungal, anticancer and antibacterial activity (Calisto et al, 2019;Graça et al, 2015Graça et al, , 2016Santos et al, 2019Santos et al, , 2020. The actinobacterial genus Streptomyces, which demonstrated the highest potential to control phytopathogenic bacteria and fungi (e.g., chlortetracycline from S. aureofaciens), has been the most extensively studied group among bacteria (Liotti et al, 2019), contrary to Planctomycetes.…”

included five Psa and one Pseudomonas sp. (B65). All the Pseudomonas strains used in this study shared common characteristics regarding swimmingmotility, no biofilm-production in abiotic surfaces and production of indole-3-acetic acid (IAA) using a tryptophan-dependent pathway, showing the maintenance of virulence traits in culture. Four representative Pseudomonas strains were exposed to the marine Actinobacteria and Planctomycetes extracts obtained by liquid-liquid phase (LLPE). Only the planctomycetes Alienimonas chondri, Rhodopirellula rubra, Rubrinisphaera brasiliensis and Novipirellula caenicola inhibited Pseudomonas growth with percentages

“…Therefore, they are extensively used in agricultural industries ( Sousa & Olivares, 2016 ; Vurukonda, Giovanardi & Stefani, 2018 ). It has been demonstrated that actinobacteria protect crops against pathogens, including tomato ( Goudjal et al, 2016 ), pepper ( Liotti, da Silva Figueiredo & Soares, 2019 ), cereal ( Newitt et al, 2019 ), rice ( Xu et al, 2017 ), and strawberry ( Marian et al, 2020 ).…”

The root-associated actinobacteria play important roles in plant growth, nutrient use, and disease resistance due to their functional diversity. Salvia miltiorrhiza is a critical medicinal plant in China. The root actinobacterial community structure has been studied; however, the functions of root-associated actinobacteria of S. miltiorrhiza have not been elucidated. This study aimed to decipher the diversity and function of the culturable root-associated actinobacteria in plant growth using culture-dependent technology and culturable microbe metagenomes. We isolated 369 strains from the root-associated actinobacteria, belonging to four genera, among which Streptomyces was dominant. Besides, the functional prediction revealed some pathways related to plant growth, nitrogen and phosphorus metabolism, and antagonistic pathogens. We systematically described the diversity and functions of the culturable root-associated actinobacteria community. Our results demonstrated that the culturable root-associated actinobacteria of S. miltiorrhiza have rich functionalities, explaining the possible contribution of culturable root-associated actinobacteria to S. miltiorrhiza’s growth and development. This study provides new insights into understanding the function of the culturable root-associated actinobacteria and can be used as a knowledge base for plant growth promoters and biological control agent development in agriculture.

“…2, 4-Diacetyl-phloroglucinol was a phenolic compound produced by Pseudomonas, that has anti-viral, anti-fungal and preventive activity against other bacteria (Hao 2010). Streptomyces griseocarneus R132 inhibited the growth of plant pathogens with a range of 57.24 ± 4.54% (Fusarium oxysporum 46.7) to 73.93 ± 3.71% (Botryosphaeria dothidea CFMAC3), which apparently controlled the development of anthracnose symptoms caused by Colletotrichum gloeosporioides (Liotti et al 2019). Although there have been many studies on antagonistic endophytic bacteria, they have not been reported with biological control function against C. scovillei.…”

Anthracnose caused by Colletotrichum spp. is a well-known disease that causes severe losses in pepper production which is used as a spice for thousands of households in many parts of China. With the biological control properties of endophytic strains have been developed and used have been of great importance in the prevention and control of anthracnose and environmental protection. Therefore, to control the pathogen Colletotrichum scovillei more safely, 58 endophytic strains were isolated from pepper leaves in this experiment. Plate resistance method was used to screen the antagonistic strains of C. scovillei, and it was found that the inhibition rate of 25 antagonistic strains against C. scovillei was greater than 60%, and the inhibitory rates of L1-7 and L3-5 against it were 79% and 80%, respectively. They were identified as Bacillus amyloliquefaciens and Bacillus velezensis by culture and morphological identification, combined with 16S rDNA and gyrB gene sequence analysis. The two antagonistic endophytic bacteria also had the ability to fix nitrogen and secrete IAA, and all had high salt tolerance. Controlled pot experiments in the laboratory showed that L1-7 and L3-5 had a good control effect against C. scovillei, with the control efficiency reaching 80.64% and 73.39%, respectively. Thus, B. amyloliquefaciens (L1-7) and B. velezensis (L3-5) could be useful as biological control agents to protect peppers from anthracnose disease caused by C. scovillei. The results of this test provide a basis for the development of pepper endophytic bacterial resources, and also bacterial resources for the biological control of C. scovillei.
