MS-based metabolomics approach reveals a potential alternative in HLB diagnosis in citrus leaves: using multivariate data analysis and molecular networking

Citriculture is one of the most important economic activities in Brazil. However, the disease huanglongbing, caused by CLas bacterium, is the most destructive disease in the whole world.
Mass Spectrometry (MS) analytical approaches were used as an alternative to monitoring the metabolic modification in citrus leaves infected by CLas.
Some biomarkers were detected in imaging MS and LC/GC-MS and can be used as a
target to follow the HLB infection process in citrus.
