General Information

EC Number General Information Comment Organism
4.2.1.92 malfunction silencing HPL in wild-type Solanum lycopersicum increases potato aphid (Macrosiphum euphorbiae) host preference and reproduction on 5-week-old plants but has no influence on 3-week-old plants. Silencing HPL in spr2 mutants does not compromise this aphid resistance. Moreover, a mutation in the FAD7 gene in Arabidopsis thaliana also confers resistance to the green peach aphid (Myzus persicae) in a genetic background that carries a null mutation in HPL Solanum lycopersicum
4.2.1.92 metabolism enzyme HPL is important in the biochemical pathway for synthesis of C6 volatiles in Solanum lycopersicum, pathway overview Solanum lycopersicum
4.2.1.92 physiological function the HPL pathway can influence direct defenses against insects, volatiles (E)-2-hexenal, hexanol, (E)-2-hexenol, and (Z)-3-hexenol reduce aphid fecundity. HPL contributes to certain forms of aphid resistance in tomato, but that the effects of fatty acid desaturase 7 (FAD7) on aphids in tomato and Arabidopsis are distinct from and independent of HPL. Disrupted function of FAD7, confers resistance to the potato aphid (Macrosiphum euphorbiae) and modifies the plant's C6 volatile profiles in Solanum lycopersicum. Moreover, a mutation in the FAD7 gene in Arabidopsis thaliana also confers resistance to the green peach aphid (Myzus persicae) in a genetic background that carries a null mutation in HPL Solanum lycopersicum
