Huanglongbing disease (citrus greening; HLB) is currently the most economically damaging disease of citrus trees, and has been associated with the collapse of the several citrus industries in Asia and America. The disease is associated with the presence of a phloem restricted alpha proteobacteria species of the ‘Candidatus Liberibacter’ genus. ‘Candidatus Liberibacter asiaticus’ (CLas) is the dominant species found in South America (Lopes et al. 2009). In 2017, branches were collected from Citrus sp. trees showing mild to severe yellowing on the shoots, lopsided and greening fruits and tree decline in various regions in Venezuela. To verify the presence of CLas, total DNA was extracted from single leaf midribs and subjected to PCR amplification with primers sets OI1/OI2c targeting the 16S rDNA locus (Jagoueix et al. 1994) and A2/J5 targeting the beta-operon locus of ribosomal proteins (Hocquellet et al. 1999). A total of 87 out of 104 samples (83.7%) tested positive with both primer sets. The OI1/OI2c primers generated an amplicon of approximately 1160 bp and digestion by XbaI yielded two DNA fragments of approximately 640 bp and 520 bp, suggesting the presence of CLas (Jagoueix et al. 1994). The A2/J5 primer set generated a ~703-bp amplicon, suggesting ‘Candidatus L. africanus’ was not present. Two of the A2/J5 amplicons were purified, cloned and sequenced. The derived sequences have been deposited in the GenBank database under accession Nos. MG418842 and MG418841. Sequence comparison revealed that MG418842 and MG418841 shared >99% identity to the corresponding regions of CLas in the GenBank database. To our knowledge, this is the first report of molecular identification of CLas infecting citrus in Venezuela.
