SigA-binding protein (SIB A) is a nuclear-encoded chloroplast-targeted protein that interacts with the plastid-encoded plastid RNA polymerase σ-factor SigA (Sig1). In this study, the SIB A gene responded rapidly to salicylic acid (SA) treatment, but responded slowly to ethylene (ET) and jasmonic acid (JA) treatments as determined with microarray and(More)
Strategies employed for the production of genetically modified (GM) crops are premised on (1) the avoidance of gene transfer in the field; (2) the use of genes derived from edible organisms such as plants; (3) preventing the appearance of herbicide-resistant weeds; and (4) maintaining transgenes without obstructing plant cell propagation. To this end, we(More)
Fava beans are eaten all over the world and recently, marketing for their sprouts began in Japan. Fava bean sprouts contain more polyphenols and l-3,4-dihydroxyphenylalanine (l-DOPA) than the bean itself. Our antioxidant screening program has shown that fava bean sprouts also possess a higher antioxidant activity than other commercially available sprouts(More)
