Expression of Odc, Adc, and Samdc genes in Theobroma cacao were induced under different stresses such as, drought and infection with Phytophthora megakarya, or the necrosis inducing protein Nep1 from Fusarium oxysporum while Spds and Sps were not changed (Bae et al., 2008). The gene discussed is SMS; the disease is infection.
