The cDNA was cloned into eukaryotical expression plasmid pcDNA3. SMART TM protocol was used for cDNA library construction and bioinformatics analysis was carried out. 71 novel EST clones were obtained from 130 sequences in the library, of which there were 21 full-length clones, including cytolysin genes, flourescent protein, ubiquinol-cytochrome C reductase gene, elongation factor, ferritin gene riboflavin kinase gene, ribosomal protein. This provides a base for further investigating their biological activity and application.展开更多
A 花的颜色不同主要是因为花瓣内所含化合物的成分(色素)不同。这些化合物大致可以分为两种,即花青素和胡萝卜素。花青素极不稳定,遇酸呈红色,遇碱呈蓝色,中性呈紫色,酸碱性的强弱还直接影响着色彩的深浅。胡萝卜素能使花呈现出黄、橙...A 花的颜色不同主要是因为花瓣内所含化合物的成分(色素)不同。这些化合物大致可以分为两种,即花青素和胡萝卜素。花青素极不稳定,遇酸呈红色,遇碱呈蓝色,中性呈紫色,酸碱性的强弱还直接影响着色彩的深浅。胡萝卜素能使花呈现出黄、橙、红等色彩,而胡萝卜素种类较多,目前已知的有八十多种。自然界的植物种类繁多,它们生存的环境也各不相同,在两种色素的作用下,植物才能开出五彩缤纷的花朵。展开更多
