摘要:
最早在细菌中，由美国科学家Herve Tettel等，于2005年提出了泛基因组(Pan-genome)概念。泛基因组展示由核心基因组、特有基因组、非必须基因组3部分组成。本文在反溯泛基因组概念的提出、发展、衍变过程的基础上，重点关注了其在生物领域的主要研究历程，特别是在系统演化、生物多样性、基因挖掘、适应性与抗逆性等方面的主要研究成果。由于竹类是多年生一次开花的独特植物，故依据传统的以花、果等器官进行植物分类存在很大的局限性。根据我们在研究竹类植物的表型、生理、生态等方面的多样性遇到的问题，提出竹类植物需要强化泛基因组研究，以破解更多竹学难题。
Pan-genome was firstly proposed by American scientists Herve Tettel et al. in 2005 in bacteria. Pan-genome includes core genome, specific genome and dispensable genome. In this paper, based on retrospection of the concept of pan-genome, development and evolution process, we pay attention to the research process in biological field significantly, and get main research achievements, especially in systematic significations, biological diversity, gene-explore, adaptability and resistance. Because of the particularity of flowering only once in bamboo’s lifetime, the traditional classification method which contains flower and fruit has great restrictions. According to the problems of phenotype, physiology and ecology in the study, we offer a proposal in bamboology; pan-genome should be strengthened to resolve some difficult problems of bamboo.
