Abstract
Potato zebra chip (ZC) disease, associated with the uncultured phloem-limited bacterium, Candidatus Liberibacter solanacearum (CLso), is transmitted by the potato psyllid Bactericera cockerelli. Potato ZC disease poses a significant threat to potato production worldwide. Current management practices mainly rely on the control of the psyllid to limit the spread of CLso. The present study investigated new sources of ZC resistance among wild Solanum species. A taxonomically diverse collection of tuber-bearing Solanum species was screened; one ZC-resistant accession and three ZC-tolerant accessions were identified among the 52 screened accessions. Further characterization of the resistant accession showed that the resistance was primarily associated with antibiosis effects due to differences in leaf trichome density and morphology of the wild accession, which could limit the psyllid feeding and oviposition. This germplasm offers a good resource for further understanding ZC and psyllid resistance mechanisms, contributing to potato breeding efforts to develop ZC resistance cultivars. Alternatively, it could be used as a potential trap crop to manage psyllid and control ZC disease.

Contreras-Rendón A, Sánchez-Pale JR, Fuentes-Aragón D, Alanís-Martínez I, Silva-Rojas HV. Conventional and qPCR reveals the presence of 'Candidatus Liberibacter solanacearum' haplotypes A, and B in Physalis philadelphica plant, seed, and Βactericera cockerelli psyllids, with the assignment of a new haplotype H in Convolvulaceae. Antonie van Leeuwenhoek 2019; 113:533-551.

Abstract
The husk tomato (Physalis philadelphica Lam.) is an important Solanaceae native to Mesoamerica that is grown for its green fruit used as an important ingredient in domestic and international cuisine. Nevertheless, husk tomato plants with symptoms resembling those caused by 'Candidatus Liberibacter solanacearum' (CLso) have been observed during the last decade in plantations located in the State of Mexico, Michoacan and Sinaloa in Mexico. These areas are located near other solanaceous crops where Bactericera cockerelli the well-known psyllid transmitter of CLso is frequently present. Thus, the goal of this study was to determine if CLso haplotypes are present in husk tomato varieties in commercial fields in Mexico. From 2015 to 2016, plants and fruit showing evident symptoms of CLso infection, as well as psyllids were collected in these states and assayed by PCR for CLso using primer sets OA2/OI2c and LpFrag 1-25F/427R. Phylogenetic reconstruction was performed with Bayesian analysis and maximum likelihood methods using amplicon sequences obtained in this work along with those deposited in the GenBank database corresponding to the CLso detected in Solanaceae, Apiaceae, and Convolvulaceae host families. In addition, all the sequences were subjected to haplotype determination through an analysis of DNA polymorphisms using the DnaSP software. Furthermore, quantitative PCR (qPCR) was performed using CLso-specific primers and probes. Phylogenetic reconstruction and qPCR confirmed the presence of CLso in plants, seeds and insect-vectors, and CLso sequences from plants and seeds completely matched haplotype B, whereas CLso haplotypes A and B were detected in B. cockerelli psyllids. Polymorphism analysis identified a novel Convolvulaceae-associated CLso haplotype, which was named haplotype H. The results of this study will enable the dissemination of infected seeds to new husk tomato production areas to be avoided.

Abstract
The potato/tomato psyllid,Bactericera cockerelli(Sulc) (Hemiptera: Triozidae) has been a major pest of solanaceous crops for decades. This pest can cause damage to crop plants by direct feeding and, as has been recently discovered, by transmitting the bacterial pathogenCandidatusLiberibacter psyllaurous (a.k.a.Ca.L. solanacearum). Many studies have been conducted to determine the relationship of this pest to plant injury and to develop management strategies to alleviate the damage caused by this pest in a wide variety of solanaceous plants. Studies in the past decade have documented substantial genetic variability in this invasive species, enhanced our rapidly-evolving understanding of the interactions between the insect and the pathogen it carries, and improved our appreciation of the invasive potential of the pest. This review seeks to provide a comprehensive update toB. cockerellilife history, relationship to plant diseases, and the current state of management strategies againstB. cockerelli.
