Fig 1. Atalantia buxifolia resistance to citrus canker.
The phylogenetic tree was constructed by using the maximum likelihood tree method and the substitution model GTRGAMMA in the RAxML software. Murraya koenigii was used as the outgroup. Fully expanded leaves were treated with Xcc (108 CFU/mL) to evaluate citrus canker resistance. The symptoms were observed at 7 and 12 d after inoculation. Red indicates canker susceptible citrus (Wild pummelo: purple pummelo; Cultivated pummelo: guanxi pummelo; Cultivated mandarin: Ponkan; Lemon: Eureka lemon). Purple indicates canker tolerant citrus (Wild mandarin: mangshan mandarin). Green indicates canker-resistant citrus. Bootstrap values greater than 60 are labelled at the node in the tree. Scale bars, 1 cm.
