Project description:Crude extracts of 1L cultures of fungal and bacterial strains isolated from citrus trees under high HLB pressure, grown for 1 week. All showed in vitro inhibition of Liberibacter crescens.
Project description:LC-MS/MS data of crude extracts produced by isolated bacteria recovered from Brazilian Rocas Atoll. Subset of MSV000083601 for use as an example dataset on the Workshop on Advanced Mass Spectometry 2025.
Project description:Lisbon lemon trees were grafted with budwood infected with the citrus greening bacterium, 'Candidatus Liberibacter asiaticus', or control budwood, and leaf samples were collected every two weeks post graft for LC/MS analysis. This project has shotgun proteomics data for leaf samples from 5 control and 5 CLas grafted trees at the 10 week post graft timepoint.

This project has shotgun proteomics data for leaf samples from 5 control and 5 CLas grafted trees at the two week post graft timepoint.
Project description:Lisbon lemon trees were grafted with budwood infected with the citrus greening bacterium, 'Candidatus Liberibacter asiaticus', or control budwood, and leaf samples were collected every two weeks post graft for LC/MS analysis. This project has shotgun proteomics data for leaf samples from 5 control and 5 CLas grafted trees at the 14 week post graft timepoint.
Project description:We evaluated the effect on citrus trees of two newly-identified molecules, benzbromarone and tolfenamic acid, used as antimicrobials in commercial groves of sweet orange (Citrus sinensis). We delivered the molecules by trunk injection and evaluated safety and efficacy parameters by performing RNAseq of the citrus host responses.
Project description:Navel orange trees were grafted with budwood infected with the citrus greening bacterium, 'Candidatus Liberibacter asiaticus', or control budwood, and leaf samples were collected every two weeks post graft for LC/MS analysis.
Project description:Huanglongbing (HLB) is considered the most destructive disease in Citrus production and threatens the future of the industry. Microbial derived defence elicitors have gained recognition for their role in plant defence priming. A transcriptomic assessment using GeneChip microarray of the hour 6 samples revealed differential expression of 565 genes when MFA was applied to healthy trees and 909 genes when applied infected citrus trees when compared to their respective controls. There were 403 uniquely differentially expressed genes in response to MFA following an intersectional analysis of both healthy and infected citrus trees. The transcriptomic analysis revealed that several genes associated with plant development, growth and defence were upregulated in response to MFA, including, multiple PR genes, lignin formation genes, ROS related genes, hormone synthases and hormone regulators.
