摘　　要：赖氨酸被认为是稻米中的第一限制性必需氨基酸,提高谷物中赖氨酸含量一直是禾谷类作物营养品质改良的重要目标之一。本研究采集江苏地区3个不同试验田的10种稻米样品,以粳稻品种武香粳9号作为野生型亲本,对水稻胚乳中赖氨酸代谢途径进行改造,对培育出的多份高赖氨酸基因修饰稻米新种质进行赖氨酸、总蛋白、总糖、总脂肪、总水分主要营养成分含量测定,建立了多种高赖氨酸基因修饰稻米主要营养成分含量数据集。数据采集和处理过程严格遵循测量仪器数据质量控制和规范的要求。通过本数据集的建立,可系统展示多种高赖氨酸基因修饰稻米主要营养成分含量情况,了解不同类型高赖氨酸基因修饰稻米的主要营养成分的差异性;为其赖氨酸代谢改变后,是否会对稻米品质等产生影响,以及对探究其影响因素提供科学依据,为高赖氨酸稻米的品质评价及调控提供数据参考。Lysine is considered as the first limiting essential amino acid in rice,and increasing its content in grains has long been an important goal in improving the nutritional quality of cereal crops.This study collected ten rice samples from three different experimental fields in Jiangsu Province.Using the japonica rice variety Wuxiangjing 9 as the wild-type parent,the lysine metabolism pathway in the rice endosperm was modified.Multiple new high lysine gene-modified rice germplasms were cultivated,and their nutritional components(including lysine,total protein,total sugar,total fat,and total water)was analyzed and determined.Based on this,a dataset of main nutritional components in 9 lysine gene-modified rice varieties was established.The data collection and processing strictly followed quality control and standards of measurement instrument regulations.The dataset systematically presents the key nutritional components of various types of high lysine gene-modified rice varieties.Additionally,it provides a scientific basis for assessing whether modifications in lysine metabolism affect rice quality and explores potential influencing factors,and to offer data reference for the quality evaluation and regulation of high lysine rice.
