This study employs integrated transcriptomic and metabolomic analyses on potato cultivar 'Jizhangshu 12' under moderate and severe drought stress to uncover key regulatory networks. Pathway enrichment highlighted phenylpropanoid-flavonoid biosynthesis, lipid metabolism, and MAPK-hormone signaling as core response modules. Core candidate genes, including COMT1, F3'H, an ABCG transporter, and a WRKY transcription factor, were identified to facilitate breeding for drought-tolerant potatoes.
This study provides genomic and ecological evidence that the potato psyllid (Bactericera cockerelli), a critical vector of the potato zebra chip pathogen Candidatus Liberibacter solanacearum (CLso), comprises at least three genetically distinct cryptic species. The lineages display strong reproductive isolation, distinct Solanaceae host plant associations, and differences in harbored CLso variants. These findings offer important insights for managing potato psyllid populations and biosecurity strategies against zebra chip disease.
This study investigates the cellular regulation of sucrose transporters, including potato StSUT1, demonstrating that plasma membrane lipid composition affects their localization, abundance, and uptake activity. The findings provide insights into the post-translational and membrane-environment regulation of phloem loading in potato.
