Citrus canker, caused by the Gram-negative bacterium Xanthomonas citri subsp. citri (Xac), is one of the most devastating diseases to affect citrus crops. There is no treatment for citrus canker; effective control against the spread of Xac is usually achieved by the elimination of affected plants along with that of asymptomatic neighbors. An in depth understanding of the pathogen is the keyston...

Ferredoxin-NADP(H) reductases (FNRs) deliver NADPH or low potential one-electron donors to redox-based metabolism in plastids and bacteria. Xanthomonas citri subsp. citri (Xcc) is a Gram-negative bacterium responsible for citrus canker disease that affects commercial citrus crops worldwide. The Xcc fpr gene encodes a bacterial type FNR (XccFPR) that contributes to the bacterial response to oxid...

Citrus bacterial canker caused by Xanthomonas axonopodis pv. citri is a serious disease that impacts citrus production worldwide, and X. axonopodis pv. citri is listed as a quarantine pest in certain countries. Biofilm formation is important for the successful development of a pathogenic relationship between various bacteria and their host(s). To understand the mechanisms of biofilm formation b...

Citrus fruits of industrial interest include lemons, oranges, mandarins, grapefruits, clementines, limes and other commercially minor ones. A huge amount agricultural waste is generated yearly all over the globe by citrus fruit industry. The wastes from these productions may be, however, great nutritional economic value for their chemical composition, due to abundance diverse functional compoun...

Burkholderia andropogonis was first described as the causal agent of stripe disease of sorghum and leaf spot of velvet bean in 1911 (20); at that time, it was classified as Pseudomonas andropogonis. Pseudomonas woodsii was also described, in the same publication, as an important pathogen of carnation. These two pathogens were reclassified to the genus Burkholderia based on DNA-rRNA hybridizatio...

Imidacloprid (IM) is used to control the Asian Citrus Psyllid (ACP) and citrus leafminer (CLM), which are related to the spread of huanglongbing (HLB or citrus greening) and citrus canker diseases, respectively. In Florida citrus, imidacloprid is mainly soil-drenched around the trees for proper root uptake and translocation into plant canopy to impact ACP and CLM. The objective of this study wa...

Citrus (family Rutaceae) stands as a prominent fruit crop on global scale, bearing substantial significance. Renowned for its abundance of fiber, amino acids, antioxidants, vitamin C, and carbohydrates. However, the successful production citrus is persistently challenged by menacing presence canker caused Xanthomonas citri subsp. (Xcc), posing 5-30% yield losses in Pakistan. Current study was a...

This study describes the use of electroporation for transforming Xanthomonas axonopodis pv. citri (Xac), the causal agent of citrus (Citrus spp.) canker. It also evaluates the methodology used for this species under different electrical parameters. The bacterium used in the study (Xac 306) was the same strain used for recent complete sequencing of the organism. The use of a plasmid (pUFR047, ge...
