General Information

EC Number General Information Comment Organism
2.1.1.270 metabolism the differential expression of 13 defence-related genes during Phoma koolunga infection of stems and leaves of susceptible versus resistant field pea (Pisum sativum) determined by quantitative RT-PCR shows that expression, in terms of relative mRNA level ratios, of genes encoding ferredoxin NADP oxidoreductase, 6a-hydroxymaackiain methyltransferase (hmm6), chalcone synthase (PSCHS3) and ascorbate peroxidase in leaves and stems vary during 6-72 hours post-inoculation (hpi) and reflecting host resistance levels in leaves versus stems. In comparison to the susceptible genotype, at 24, 48 and 72 hpi, two genes, hmm6 (122, 207 and 32fold, respectively) and PSCHS3 are strongly upregulated in leaves of the resistant genotype, highlighting that resistance against Phoma koolunga in field pea is governed by the early synthesis of pisatin, overview Pisum sativum
2.1.1.270 physiological function resistance against Phoma koolunga in field pea is governed by the early synthesis of pisatin involving the enzyme hydroxymaackiain methyltransferase Pisum sativum
