Cassava bacterial blight (CBB) is a systemic disease caused by Xpm, which might have dramatic effects on plant growth and crop production. Cassava bacterial necrosis is a nonvascular disease caused by Xc with foliar symptoms similar to CBB, but its impacts on the plant vigour and the crop are limited. In this review, we describe the epidemiology and ecology of the two pathogens, the impacts and management of the diseases, and the main research achievements for each pathosystem. Because Xc data are sparse, our main focus is on Xpm and CBB. specialized cassava cassava bacterial blight cassava bacterial necrosis quantitative resistance Xanthomonas 076 22 12 1520-1537 2021 1464-6722 https://www.documentation.ird.fr/hor/fdi:010082248 10.1111/mpp.13094 1464-6722 [F B010082248] https://www.documentation.ird.fr/hor/fdi:010082248 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/2021-08/010082248.pdf IRD - Base Horizon / Pleins textes 2021-08-31 2025-02-24 fdi:010082248 fre
