Briefings

A new breeding advance targets bacterial leaf blight in East African rice, a disease caused by Xanthomonas oryzae pv. oryzae (Xoo) that causes significant yield losses. The evidence indicates this bacterium has many distinct regional strains across continents, complicating control efforts.

Key points

• The disease bacterial leaf blight (BB) causes significant yield losses in Asia and Africa.
• The bacterium responsible is Xanthomonas oryzae pv. oryzae (Xoo), which has many distinct regional strains on various continents.

Context

Bacterial leaf blight is a major threat to rice production in East Africa, with Xanthomonas oryzae pv. oryzae (Xoo) causing widespread crop damage. The evidence highlights the global spread of the bacterium across different continents, making regional strain variation a key factor in disease management.

Limitations

Evidence is limited to the specific disease and bacterium mentioned; no data on breeding progress, impact metrics, or regional strain prevalence is provided.
