籽粒苋（Amaranthus cruentus L.）核糖体蛋白S25基因（cDNA）的克隆及其表达分析

Ribosomes, the agents of protein synthesis, consist of roughly equal amounts of RNA (rRNA) and protein (r-protein). Knowledge of the ribosome and its function mainly comes from the extensive work on 70S bacterial ribosomes. There are 21 proteins in the small (30S)subunit and 30 in the large (50S) subunit in E. coil ribosomes. The 80S eukaryotic ribosomes are more complex than the bacterial ones and contain at least 30 proteins in the small (40S) subunit and 40 in the large (60S) subunit. These r-proteins are named S1 to S30 and L1 to L40 according to whether they arise from the small or large subunit, and to their mobility in gels. In plants,several ribosomal protein genes and/or cDNAs have been isolated, such as the small subunit proteins S 11,S13, S14, S16, and S19 and the large subunit proteins L2, L7, L17, and L27. Here we report the r-protein S25 cDNA, Arps25, from Amaranthus cruentus L.
