HIGH CAROTENOID MAIZE
- Summary
- Guelph researchers have developed a series of maize inbred lines with high carotenoid content in the kernels. These inbred lines are adapted to short-season environments. Carotenoids are a large group of yellow-red pigments synthesized by all plants. Animals, unlike plants, are not able to synthesize carotenoids on their own; rather carotenoids are acquired through their diet, primarily through fruits and vegetables. The interest in dietary carotenoids comes from their anti-oxidant properties and the association between carotenoid deficiencies and many chronic human diseases. Researchers have increased the basal level of two carotenoids - lutein and zeaxanthin. These carotenoids were targeted because of their importance in prevention of age-related macular degeneration (ARMD). ARMD is a condition that affects the center of the field of vision and the ability to see fine detail. Diets rich in lutein and zeaxanthin, are one of the options currently available to delay the onset of ARMD.
圭尔夫大学的研究人员已经研究出了一系列在玉米芯中具有高含量类胡萝卜素的玉米自交系品种。这些自交系适用于短季环境。 类胡萝卜素是所有植物合成的黄-红色素的总称。与植物不同，动物不能靠自己本身合成类胡萝卜素，而只能通过饮食摄取，主要来自于水果和蔬菜。人们对膳食类胡萝卜素的兴趣，主要来源于它们的抗氧化性，以及很多人类慢性疾病都与缺乏类胡萝卜素有关。 研究人员已经提高了两种类胡萝卜素—“叶黄素和玉米黄质”的基础含量水平。将这两种类胡萝卜素作为研究目标是因为它们对预防老年性黄斑变性（ARMD）有重要作用。ARMD影响视野中心以及观看精致细节的能力。富含叶黄素和玉米黄素的饮食是目前可行的延缓ARMD发病的选择之一。Advantages • Carotenoid levels 2-3 fold higher than conventional corn lines. • Higher levels of lutein and zeaxanthin than conventional lines. • Not transgenic. • Lines are adapted for use in Ontario and similar climate regions. Potential Markets Development of high-carotenoid varieties of maize for short-season and other climatic regions.
