Biocontrol Agents for Controlling Wheat Rust.

Area of Science:

• Agricultural Microbiology
• Plant Pathology
• Biotechnology

Background:

• Wheat rust diseases pose significant threats to global food security.
• Bacterial endophytes offer a sustainable approach for crop protection and yield improvement.
• The efficacy of endophytic bacteria varies, necessitating targeted isolation and screening.

Purpose of the Study:

• To isolate and identify endophytic bacteria with biocontrol potential against wheat rusts.
• To evaluate the growth-promoting capabilities of selected endophytic bacterial isolates.
• To establish a methodology for discovering potent endophytic agents for wheat cultivation.

Main Methods:

• Isolation of endophytic bacteria from wheat tissues.
• Screening for suppression of wheat strip rust infection in vitro and in vivo.
• Identification of promising isolates using molecular techniques.
• Assessment of plant growth-promoting activities.

Main Results:

• Several endophytic bacterial isolates demonstrated significant suppression of strip rust pathogen.
• A subset of these isolates exhibited notable plant growth-promoting effects.
• Variability in biocontrol and growth-promotion was observed among isolates.

Conclusions:

• Endophytic bacteria are viable biocontrol agents for wheat rusts.
• Specific isolates possess dual capabilities for disease suppression and yield enhancement.
• The described procedure facilitates the discovery of beneficial endophytic bacteria for agriculture.
