阅读说明：本技术 抗除草剂多肽、核酸及其应用 (Herbicide-resistant polypeptide, nucleic acid and application thereof ) 是由 王木桂 牛小牧 张金山 王飞 于 2021-01-21 设计创作，主要内容包括：本发明提供了抗除草剂多肽、核酸及其应用,具体地,提供了抗除草剂基因、多肽及其在植物育种中的应用,具体地,本发明提供了一种突变的HPPD多肽,并且所述突变的HPPD多肽与亲本HPPD多肽相比,在对应于SEQ I D NO.1的第347位氨基酸和/或第353位氨基酸发生突变。突变后的HPPD多肽对除草剂具有很强的耐受性,在提高和培育抗HPPD抑制性除草剂耐受性植物领域中具有非常广阔的应用前景。(The invention provides herbicide-resistant polypeptides, nucleic acids and applications thereof, in particular herbicide-resistant genes, polypeptides and applications thereof in plant breeding, and particularly provides a mutant HPPD polypeptide, and compared with a parent HPPD polypeptide, the mutant HPPD polypeptide is mutated at the 347 th amino acid and/or 353 rd amino acid corresponding to SEQ ID NO. 1. The mutated HPPD polypeptide has strong tolerance to herbicides and has very wide application prospect in the field of improving and cultivating plants resistant to HPPD inhibitory herbicides.)
