Citrus bacterial canker (CBC) disease occurs worldwide and incurs considerable costs both from control measures and yield losses. Bacteria that cause CBC require one of six known type III transcription activator-like (TAL) effector genes for the characteristic pustule formation at the site of infection. Here, we show that Xanthomonas citri subspecies citri strain Xcc306, with the type III TAL e...
Citrus canker is a quarantined disease caused by the bacterial plant pathogen Xanthomonas citri subsp. (Xcc), which causes persistent surface damage, leaf and fruit drop, tree decline in citrus plants. The cultivar Citron C-05 (Citrus medica L.) disease-resistant genotype identified after years of screening at National Center for Improvement (Changsha), displays allergic, necrotic, responses to...
Pitch canker, caused by Gibberella circinata, was discovered in California in 1986. Although initially quite damaging to Monterey pines (Pinus radiata), the severity of pitch canker has moderated in areas where the disease was first observed and some trees appear to have recovered completely. The absence of symptoms on trees that were once severely affected implies they have become more resista...
Control of citrus canker (caused by Xanthomonas citri subsp. citri) on grapefruit is required to reduce blemishes on fresh fruit. The objective was to evaluate formulations, rates, duration of residues for copper materials, combinations of copper materials and streptomycin, and application timing for effective canker control on young, fruiting grapefruit trees. Copper applications were made at ...
