Transcriptomic Profiling of ‘Candidatus Liberibacter asiaticus’ in Different Citrus Tissues Reveals Novel Insights into Huanglongbing Pathogenesis

​‘Candidatus Liberibacter asiaticus’ (Las) is a gram-negative bacterial pathogen associated with citrus huanglongbing (HLB) or greening disease. Las is transmitted by the Asian citrus psyllid (ACP) where it colonizes the phloem tissue, resulting in substantial economic losses to the citrus industry worldwide. Despite extensive efforts, effective management strategies against HLB remain elusive, necessitating a deeper understanding of the pathogen's biology. In this MPMI Editor's Pick, Amelia Lovelace et al. investigate the transcriptomic landscape of Las in citrus seed coat vasculatures, enabling a complete gene expression profiling of Las genome and revealing unique transcriptomic patterns compared with previous studies using midrib tissues.
