Metabolites induced by citrus tristeza virus and ‘Candidatus Liberibacter asiaticus’ influence the feeding behavior of Diaphorina citri: an electrical penetration graph and LC–MS/MS study

Abstract
Abstract Citrus Huanglongbing and Citrus tristeza are two diseases that affect the citrus industry worldwide. The pathogens causing these diseases are the phloem-limited bacteria ‘Candidatus Liberibacter spp.’ (mainly Ca. L. asiaticus, CLas) and citrus tristeza virus (CTV). We recently found that both CLas and CTV could be acquired and retained by the Asian citrus psyllid Diaphorina citri. However, the mechanism through which CLas and CTV interact with the insect vectors and plant host

Abstract
Citrus HLB, caused by Candidatus Liberibacter asiaticus (CLas), is the most devastating citrus disease worldwide. Usually 10% of total genes in bacteria are regulatory genes, but only 2% of CLas genes encode transcriptional factors. Here, 20 transcriptional regulators were predicted including eight genes (lsrB, ldtR, rem, visR, visN, ctrA, mucR, pelD, and atoC) directly or indirectly involved in regulating motility, and five genes (i.e., rpoH, prbP, phrR, rirA, and lsrB) involved in oxidative s

Abstract
AbstractThis study reports the draft genome ofCandidatusPhytoplasma pyri strain P1, isolated from Argentina, marking the first global sequencing of this species. The genome assembly consisted of 16 contigs, with a total length of 575,431 bp, a GC content of 20.35%, and 125X coverage. A total of 536 genes were annotated, including those related to metabolism, genetic information processing, and signaling. Phylogenetic analysis placed ‘CandidatusPhytoplasma pyri’ within the 16SrX group, supporting

Transcriptomic Profiling of ‘Candidatus Liberibacter asiaticus’ in Different Citrus Tissues Reveals Novel Insights into Huanglongbing Pathogenesis

Abstract
‘ Candidatus Liberibacter asiaticus’ (Las) is a gram-negative bacterial pathogen associated with citrus huanglongbing (HLB) or greening disease. Las is transmitted by the Asian citrus psyllid (ACP) where it colonizes the phloem tissue, resulting in substantial economic losses to the citrus industry worldwide. Despite extensive efforts, effective management strategies against HLB remain elusive, necessitating a deeper understanding of the pathogen's biology. Las undergoes cell-to-cell movement t

Complete genome sequence of “ Candidatus Dehalogenimonas loeffleri” strain W, a highly salt-tolerant chlorinated alkane-dechlorinating bacterium isolated from estuarine sediments

Abstract
ABSTRACT “Candidatus Dehalogenimonas loeffleri” strain W, isolated from estuarine sediments, can dechlorinate 1,2-dichloroethane under high salinity. Its genome consists of a circular 1,772,240-bp chromosome with a G + C content of 52.5% and encompasses 1,763 protein-coding sequences, including 28 genes encoding reductive dehalogenases.

The complete genome sequence of the stolbur pathogen “ Candidatus Phytoplasma solani” from Pentastiridius leporinus

Abstract
ABSTRACT The complete genome of “ Candidatus Phytoplasma solani” GOE was obtained from the infected vector Pentastiridius leporinus by single-molecule real-time sequencing. This 16SrXII-P phytoplasma is associated with the economically important sugar beet disease “syndrome basses richesses.” The genome sequence is an essential resource for diagnosis and understanding pathogen–host interact
