低磷限制植物产量提高和品质改良是全球亟待解决的土壤养分问题之一,利用现代转基因技术结合常规育种手段培育磷高效新品种是解决这一问题的有效途径。目前,已有百余个磷营养效率候选基因被克隆,但真正用于植物转基因育种实践的却寥寥无几,且进展缓慢。究其原因可能是由于现有候选基因种类繁杂且未系统分类,有些基因的功能尚未明确,缺少克隆与育种交流平台等问题。鉴于此,本文将目前已克隆的植物磷营养效率候选基因按照其功能不同进行分析,对基因的生物学功能及其潜在应用价值进行归纳总结。这不仅为分子生物学家选择目标基因,解析植物磷高效分子机制提供参考,同时为育种学家进行基因转化,培育磷高效新品种搭建平台。
Low phosphorous limited plant yield and quality improvement is one of the most urgent problems to be solved in the world. It is an effective way to solve this problem by using modern transgenic technology combined with conventional breeding methods to cultivate high efficient phosphorus variety. At present, over a hundred candidates for phosphorus efficiency have been cloned, but few are used in the practice of plant genetically modified breeding, and the progress is slow. The reason may be due to the variety of existing candidate genes is not systematic and systematic classification, the function of some genes is not yet clear, the lack of cloning and breeding exchange platform and other issues. In view of this, in this paper, we have cloned the plant phosphorus nutrition efficiency candidate genes according to their different functions to analyze the biological function of genes and their potential application value summary. This not only provides a reference for molecular biologists in selecting target genes and analyzing efficient molecular mechanisms of plant phosphorus, at the same time, it is a platform for breeders to carry out gene transformation and cultivate new and efficient phosphorus cultivars.
