Subject: New hosts for citrus greening bacterium

Limonia acidissima (wood apple) and Severinia buxifolia (Chinese box orange) were recently discovered to be alternate hosts for citrus greening bacterium, Candidatus Liberobacter asiaticum. The bacterium was found to survive and multiply in both plants, but L. acidissima appeared to be only a transient host, in which the bacteria exist temporarily and then disappear. S. buxifolia proved as good a host as citrus.
