Apple (Malus×domestica) cultivar 'Fuji' has a distinguished storage capability, whereas its early harvest sport of 'Fuji', 'Hirosaki Fuji', dose not show such competence. Understanding the mechanism of the difference of storage capability between 'Fuji' and 'Hirosaki Fuji' will be very important clue to unravel the mechanism of long shelf life of 'Fuji'. Its achievement may lead to obtain a molecular marker of the selection for long shelf life in apple breeding program.'Hirosaki Fuji' is an early sport discovered at a farm at Hirosaki city in 1984 and it matures a full six weeks ahead of conventional 'Fuji'. Interestingly, the firmness of 'Hirosaki Fuji' fruit lost more rapidly than that of 'Fuji'. To know what caused the difference between 'Fuji' and 'Hirosaki Fuji' is interesting and meaningful. So I investigated the difference between 'Fuji' and its other sport cultivars in addition to 'Hirosaki Fuji'. Through the analysis of the expression of ripening related genes, it was revealed that almost all of ripening related genes including MdERF2 were expressed differently between 'Fuji' and its sport cultivars.

苹果品种富士具有较好的耐贮性，而早收品种富士的广崎富士不具有耐贮性。了解“富士”与“广崎富士”耐贮性差异的机理，将是揭示“富士”长货架期机理的重要线索。本研究为苹果耐贮藏性的选择提供了分子标记。“广崎富士”是1984年在广崎市的一个农场发现的早期运动，它比传统的“富士”提前整整六个星期成熟。有趣的是，“广崎富士”果实的硬度损失比“富士”快。了解“富士”和“广崎富士”之间的差异是有趣而有意义的。因此，我调查了'富士'和它的其他运动品种之间的差异，除了'广崎富士'。通过对成熟相关基因表达的分析，发现包括MdERF 2在内的几乎所有成熟相关基因在富士和其芽变品种中的表达都存在差异。
