Citrus canker disease caused by Xanthomonas citri subsp. citri (Xcc) is one of the most devastating biotic stresses affecting the citrus industry. Meiwa kumquat (Fortunella crassifolia) is canker-resistant, while Newhall navel orange (Citrus sinensis Osbeck) is canker-sensitive. To understand the molecular mechanisms underlying the differences in responses to Xcc, transcriptomic profiles of the...

Pectobacterium carotovorum subsp. actinidiae is the causal agent of summer canker in kiwifruit plants in South Korea. We report here the draft genome sequences of two P. carotovorum subsp. actinidiae strains, ICMP 19971 and ICMP 19972, which were originally isolated from Actinidia chinensis with symptoms of summer canker. These genome sequences will aid in the identification of genetic traits a...

Citrus canker, caused by Xanthomonas citri subsp. citri (Xcc), is severely damaging to the global citrus industry. Targeted editing of host disease-susceptibility genes represents an interesting and potentially durable alternative in plant breeding for resistance. Here, we report improvement of citrus canker resistance through CRISPR/Cas9-targeted modification of the susceptibility gene CsLOB1 ...

To study impacts of sudden oak death (SOD), a lethal bark canker disease caused by Phytophthora ramorum, we established permanent plots in Sonoma County forest types at risk of SOD. Baseline stand and tree health data were collected in 2001 and the plots were reassessed in 2004. The 250 plots (0.02 ha each) were located at 11 study locations in stands containing Quercus agrifolia, Q. kelloggii,...

Citrus canker is an important bacterial disease of citrus in several regions of the world. Strains of Xanthomonas citri type-A (Xc-A) group are the primary pathogen where citrus canker occurs. After Xc-A entered the Northeast of Argentina in 1974, the disease spread rapidly from 1977 to 1980 and then slowed down and remained moving at slow pace until 1990 when it became endemic. Citrus canker w...

Abstract During 2018–2021, a survey was conducted in rainfed fig ( Ficus carica L.) orchards throughout the Fars Province of Iran to investigate occurrence canker diseases, and identify causal organisms. Morphological cultural characteristics, as well multilocus phylogenetic analyses internal transcribed spacer (ITS) region rDNA, RNA polymerase II second largest subunit RPB2 ), translation elon...
