依据减数分裂相关基因数量判别赫氏球石藻（Emiliania huxleyi）繁殖方式研究
Ascertaining the reproduction strategy of Emiliania huxleyi by numbering its meiosis-associated genes
摘要
Abstract
Reproduction strategy is one of the most important biological characteristics of an organism. Ascertain-ing such a strategy is crucial for its genetic research and improvement. Emiliania huxleyi plays a key role in the ocean ecosystem, but nothing is known about its reproductive strategy. Here, we numbered the meiosis-associated genes of sexually reproductive eukaryotes with genome sequences that were available and found that they held ≥19 meiosis-associated genes, of which ≥5 were meiosis-specific. We also found that E. huxleyi contained 25 meio-sis-associated genes, of which 6 were meiosis-specific. Based on this information, we concluded that E. huxleyi performs sexual reproduction. This ascertainment may aid to studying its life cycle and genome and further its ge-netic improvement.关键词
