Method for evaluating oil-and-fat amount in seed and method for screening for plant exhibiting varied level of oil-and-fat content

摘要

This invention is intended to evaluate the oil-and-fat amount in a seed and genetic changes thereof. A fusion protein of an oil body-specific protein, such as the oleosin-GFP fusion protein, and a fluorescent protein is expressed, and the oil-and-fat amount in a plant seed and changes thereof are evaluated based on the fluorescent intensity in a cotyledon of a fluorescent protein, such as GFP.
