First report of 'Candidatus Liberibacter solanacearum' in.

Candidatus Liberibacters are gram-negative bacteria with a double-membrane cell envelope found in the sieve tube elements of phloem. The bacteria are transmitted by psyllids as they feed. Candidatus Liberibacter asiaticus and Candidatus Liberibacter americanus are transmitted by the adults of the citrus psyllid Diaphorina citri Kuwayana. Ca. L. africanus is transmitted by the adult psyllid.

Species of “Candidatus Liberibacter”, all vectored by psyllids, are generally recognized as the cause of four serious plant diseases, Huanglongbing, Zebra Chip, Psyllid Yellows and Yellows.

The bacterium, vectored by an insect called a psyllid, is named Candidatus Liberibacter asiaticus. The Candidatus part of the bacterium's name indicates that it cannot be cultured. Two other related forms of the disease are known, of African, and South American origin; both are also vectored by the Citrus Psyllid. The bacterium is carried by.

Bactericera cockerelli (tomato potato psyllid, TPP) is a serious pest of potato crops, causing feeding damage and also vectoring Candidatus Liberibacter solanacearum, the causal agent of the Zebra Chip (ZC) disease in potatoes.

Huanglongbing (HLB) or citrus greening disease is a destructive disease of citrus caused by gram-negative phloem-restricted bacteria belonging to the genus Candidatus Liberibacter.The genus comprises three known species: Candidatus Liberibacter asiaticus, occurring in Asian countries and, to a lesser extent, in Brazil and the USA (Florida), Candidatus Liberibacter africanus, recorded from.

In this study, the analysis for Candidatus Liberibacter was carried out following the technique described by Hansen et al. (2008) for Candidatus Liberibacter psyllaurous, which is why the presence of this species is reported in commercial potato batches in the area of Toluca, State of Mexico. However, there is molecular evidence that Candidatus Liberibacter psyllaurous and Candidatus.

This work considers both: it enables mining complex data from high impact applications, such as breast cancer diagnosis, region classification in satellite images, assistance to climate change forecast, recommendation systems for the Web and social networks; the data are large in the Terabyte-scale, not in Giga as usual; and very accurate results are found in just minutes. Thus, it provides a.
