A pathogen-exclusive nutrition niche #plantscience
A recent study by Wang et al. found that Xanthomonas exploits host carbohydrates through the conserved effector AvrBs2, which catalyzes UDP-α- D-galactose into xanthosan. Exclusively consumed by the pathogen via XanT and XanP, this ‘nutrition niche’ enables efficient carbon acquisition and virulence, offering new anti-xanthosan strategies for sustainable disease control.
