Genome-wide identification of MATE gene family in potato and functional characterization of StMATE1/4/98 in response to aluminum stress.

Plant science : an international journal of experimental plant biology | 2026-Apr-23

This study identifies 101 MATE genes in the potato genome and characterizes their expression patterns across various tissues and environmental stresses. Functional analysis reveals that StMATE1, StMATE4, and StMATE98 act as citrate transporters that enhance aluminum tolerance, providing potential genetic targets for developing stress-resistant potato cultivars.

Biochemical and genetic mechanisms of resistance in Myzus persicae: A major challenge for global crop protection.

Pesticide biochemistry and physiology | 2026-May

This review synthesizes the biochemical and genetic mechanisms of insecticide resistance in Myzus persicae (peach-potato aphid), the primary vector for major potato viruses. It details metabolic detoxification pathways and target-site mutations, providing insights essential for managing this pest and the diseases it transmits in potato cultivation.

Melatonin-dobed nano‑selenium treatment of potato plant induces direct resistance against Spodoptera litura and indirectly reshapes volatile mediated biological interactions.

Pesticide biochemistry and physiology | 2026-May

This study explores how a melatonin-selenium nanocomposite (MT-SeNC) enhances potato (Solanum tuberosum) resistance against the herbivore Spodoptera litura. The treatment triggers both direct and indirect defenses by upregulating key defense genes in the jasmonic and salicylic acid pathways and altering volatile organic compound emissions to attract natural predators.

Crustacean cardioactive peptide activates pupal ecdysial behavior in the 28-spotted larger potato ladybird.

Pesticide biochemistry and physiology | 2026-May

This study investigates the role of the crustacean cardioactive peptide (CCAP) in the pupal ecdysis of the 28-spotted larger potato ladybird (Henosepilachna vigintioctomaculata), a significant potato pest. The research demonstrates that silencing the Hvccap gene via RNA interference disrupts molting behavior and prevents successful pupation, identifying it as a potential molecular target for pest control.
