In this article we investigate multiplicative effects between genes in relation to heterosis. The extensive literature on heterosis due to multiplicative effects between characters is reviewed, as is earlier work on the genetic description of heterosis. A two-locus diallelic model of arbitrary gene action is used to derive linear parameters for two multiplicative models. With multiplicative act...
Brody, Stuart (Stanford University, Stanford, Calif.), and Charles Yanofsky. Mechanism studies of suppressor-gene action. J. Bacteriol. 90:687-695. 1965.-Mutations which change the primary structure of the A protein of the tryptophan synthetase of Escherichia coli can be reversed by allele-specific suppressor mutations. Normally, the suppressors of a particular A mutant lead to the appearance o...
to assess heritability, gene action and combining ability of rice varieties for characteristics related to grain appearance and cooking quality, the progenies derived from direct and reverse crosses of the 6×6 complete diallel together with their parents included hashemi, hassani, shahpasand, kadous, vandana and ir36 were grown in a randomized complete block design with three replications in th...
Chitosan is the main compounds of fungal species cell walls and as biotic elicitors could be used to improve secondary metabolites. In this study, we have verified the time-course of cell growth, phenylpropanoid compounds ( total phenol, flavonols, flavonoids and echinacoside) production in cells treated with chitosan. To study mechanism of chitosan action, expression of p-coumarate 3-hydroxyla...
