Identification and Characterization of LARGE EMBRYO, a New Gene Controlling Embryo Size in Rice (Oryza sativa L.).

ABSTRACT:

Background

Although embryo accounts for only 2-3% of the total weight of a rice grain, it is a good source of various nutrients for human health. Because enlarged embryo size causes increase of the amount of nutrients and bioactive compounds stored within rice grain, giant embryo mutants of rice (Oryza sativa L.) are excellent genetic resources for improving the nutritional value of rice grains.

Results

Three giant embryo mutants, including large embryo (le), giant embryo (ge) and super-giant embryo (ge^s), with variable embryo size were used in this study. We investigated whether genes controlling embryo size in these mutants (le, ge and ge^s) were allelic to each other. Although ge and ge^s was allelic to GIANT EMBRY (GE), le was not allelic t
