Host plant resistance to the two-spotted spider mite, Tetranychus urtlcae, was observed In the geranium, Pelargonium x hortorum. Initial studies Indicated an association between leaf morphology and resistance later studies concluded that resistance was due largely to the presence of glandular trlchomes which produced a toxic exudate. The active components of this exudate have been Identified as anacardlc acids. Inheritance studies Indicated that resistance was dominant to susceptibility and that two dominant complementary genes conditioned resistance.

Fig. 5. Eight highly conserved regions of the primary structure of ACC synthase. Identical amino residue relative to the sequence of CM-ACSl (from Cucurbita maxima) is shown by dot. Eleven resuidues shown to be invariant among ACC synthase and aminotransferase are marked with X. The lysine residue (Box 6) which interacts with pyridoxalphosphate and with AdoMet is marked with. However, tyrosine residue in Box 5 are replaced by phenylalanine in AVO-ACSl (from avocado) and DC-ACSl (from carnation). The numbers between the adjacent boxes show number of residues present. AVO, avocado (Persea americana Mill) MELW, melon (Cucumis melo L.) GAC, geranium (Pelargonium x hortorum). For other abbreviation of source plants, see Table 1.
