Endophytic Actinobacteria: Beneficial Partners for Sustainable Agriculture

Analogous wheat root rhizosphere microbial successions in field and greenhouse trials in the presence of biocontrol agents Paenibacillus peoriae SP9 and Streptomyces fulvissimus FU14

“…Two different soil types which were Pythium ‐infested were used and were challenged by adding biocontrol strains as seed coats in order to determine the plant and microbiota responses when exposed to such conditions. The effects observed in the wheat plants regarding root weight, plant length, and increased number of wheat heads in the presence of the FU14 strain were similar to previously published results for other biocontrol strains performed in our and other research laboratories (Cook et al , ; Franco et al , ; ; Orakçı et al , ; Yang et al , ; Cuppels et al , ; Araujo et al , ; ). In addition, it was possible not only to define a list of OTUs that characterized the core microbiota present in all stages of the crop growth but also a succession of OTUs and taxonomic groups found at particular stages.…”

“…From the perspective of microbiome management, it is important to understand which microbes are sensitive to cropping practices and whether they can be associated with other microbes to impact on plant heath, soil competition, and promote specific networking properties (Hirsch and Mauchline, ; Mendes et al , ; Massart et al , ; Schlaeppi and Bulgarelli, ; van der Heijden and Hartmann, ). Some bacterial endophytes have been shown to impact plant growth and provide protection to the plant (Araujo et al , ; ). Although the effects on plants tend to be small initially (Yang et al , ; Bokati et al , ; Araujo et al , ; Wemheuer et al , ), these valuable organisms can be used as a basis for developing safer ecological approaches to disease management, particularly against root rots that affect a range of cereals (Orakçı et al , ; Araujo et al , ).…”

It is possible that different cultivation systems, such as field versus greenhouse, may affect the soil biodiversity and promote taxa changes, even when the same starting soil is used.…”
