Publication alert – Streptomyces and their specialised metabolites for phytopathogen control.

June 16th, 2023

Streptomyces belong to class of bacteria of considerable interest to researchers as they are an important source of antibiotics for medical, veterinary and agricultural use. These bacteria occur naturally in the soil and are known to produce specialised metabolites that have antibiotic and antifungal properties. These specialised chemicals are considered to be promising biocontrol agents for the management of weed and diseases to crops. This comparative review of in vitro and in planta studies explores:

  • The methods in which the metabolites produced by Streptomyces can help defend plants from pathogens.
  • The signalling between the plant, pathogen and biocontrol agent.
  • How these the streptomyces metabolites can be used to protect crops

The development of biocontrol agents is important in maintaining crop health in light of increased demand on food crops and are considered a ‘green’ alternative to widely used synthetic chemicals used for this purpose.

In the search for new crop protection microbial biocontrol agents, isolates from the genus Streptomyces are commonly found with promising attributes.
