植酸酶研究进展及土壤植酸酶应用展望

Research Advances on Phytase and Prospect of Applying Soil Phytase

磷元素是农作物的主要营养限制因子之一,开发利用土壤中的磷资源对解决作物的磷素限制意义深远。植酸是土壤有机磷的主要形态,其矿化分解并释放有效磷的过程是一个酶促反应,植酸酶是这一过程的关键酶。植酸酶在土壤改良及农业的可持续发展领域具有较强的应用前景,高通量测序技术的出现也为土壤植酸酶研究提供了全新的思路和策略。综述了植酸酶的多样性、获取技术、提高产率的策略及在农业领域的应用现状,分析了土壤植酸酶研究存在的问题和未来发展的趋势,并对其应用前景进行了展望。

Phosphorus is a major nutrient-limiting factor in crops,and it is significant to solve the phosphorus limitation in crop by developing and utilizing the resources of soil organic phosphorus.Phytic acid acts as the major form of soil organic phosphorus,the process of its mineralization and releasing soil available phosphorus is an enzymatic reaction,and phytase is a key in this process.In present,phytase has showed great application potential in the sustainable development of agriculture.The advances of high-throughput sequencing technologies have provided new ideas and strategy on the study of soil phytase.Here,the diversity,production technique,the strategies of improving production as well as application situation in agriculture are summarized,the issues and the trends for future development of soil phytase are analyzed,and its application prospect is carried out as well.
