Predicted Secreted Proteins for the Citrus Stem-End Rot Fungal Pathogen Lasiodiplodia theobromae CITRA15
<p>Lasiodiplodia theobromae (L. theobromae) belongs to a diverse genus of fungal pathogens associated with perennial tropical fruit plants worldwide. In citrus, L. theobromae causes stem-end rot (SER), a damaging postharvest disease that is aggravated when trees are also infected with the citrus greening bacterium, a Candidatus Liberibacter asiaticus. Due to the latent infection of L. theobromae during the preharvest stage, it is also difficult to control by chemical and physical treatment. We sequenced and assembled the first genome of isolate CITRA15 of L. theobromae obtained from citrus, providing a resource for future research on postharvest and preharvest disease management of citrus and other fruit crops and diagnostics. Here we want to share a set of i) 10,496 predicted coding gene sequences (cds) and ii) 10,496 predicted proteins and ii) 1,016 predicted secreted proteins using SignalP v2.0 and TMHMM v2.0.</p> <p> </p>
Data from: Contribution of predation to the biological control of a key herbivorous pest in citrus agroecosystems
Biological control has traditionally simplified the view of trophic relationships between herbivorous pests and their natural enemies in agriculture. The success or failure of this pest management strategy is still mainly attributed to the ability of a few key natural enemies to suppress the pest density. For example, successful regulation of the California red scale (Aonidiella aurantii) a key citrus pest, is generally credited to specific parasitoids of the Aphytis genus. Currently, research is revealing how herbivore regulation in agroecosystems can be alternatively achieved with a greater number of trophic associations within the system. The goals of the present study were: i) to unravel species‐specific trophic links between A. aurantii, and its natural enemies in citrus agroecosystems, and ii) to assess their contribution to control of A. aurantii. Predation and parasitism of this herbivorous pest were assessed through exclusion experiments. Species‐specific trophic links between this herbivorous pest and its natural enemies were studied using gut‐content analysis of field collected predators employing prey specific DNA molecular markers. Relative predation rates of the species involved in A. aurantii regulation were estimated. Predation was found to be the main biotic component of A. aurantii mortality, causing reductions of more than 75% in recently settled cohorts. Aonidiella aurantii DNA was detected in the digestive system of 11 species of predators. Generalist and stenophagous predators, mainly associated with other citrus pests such as aphids, proved to be the most important biological control agents of this pest. Complex trophic relationships, such as apparent competition between two key citrus pests, were revealed. The present study highlights the role of predation as biotic mortality factor of key pests in perennial agroecosystems; wherein, it is a rich complex of indigenous or naturalized generalist predators that are primarily responsible for this mortality. The results herein presented may therefore offer another perspective on the biological control of one of the key worldwide citrus pests; at least in those regions where specific parasitoids are not able to successfully regulate the scale populations.
