BACKGROUND Cytosine methylation is involved in epigenetic control of gene expression in a wide range of organisms. An increasing number of examples indicate that changing the frequency of cytosine methylation in the genome is a feasible tool to engineer novel traits in plants. Although demethylating

Metabolic engineering for production of isoflavones in non-legume plants may provide the health benefits of these phytoestrogens from consumption of more widely used grains. In legumes, isoflavones function in both the symbiotic relationship with rhizobial bacteria and the plant defense response.

Ergosterol, a typical fungal sterol, induced in tobacco (Nicotiana tabacum L. cv. Xanthi) suspension cells the synthesis of reactive oxygen species and alkalization of the external medium that are dependent on the mobilization of calcium from internal stores. We used specific inhibitors to elucidate

OBJECTIVE Trifolium repens (white clover) is a valuable component of pastures due to its ability to fix nitrogen. Productivity of T. repens is sometimes threatened by insect pests, and it has been suggested that phenylpropanoid-derived isoflavonoids such as formononetin can protect white clover from

The expression of the Agrobacterium tumefaciens emrAB operon, which encodes a membrane fusion protein and an inner membrane protein, is inducible by various flavonoids, including apigenin, genistein, luteolin, naringenin, and quercetin. Among these flavonoids, quercetin is the best inducer, followed
