Beschreibung
Zusammenfassung:	The invention discloses an OsNramp5 mutant as well as a related product and application of the OsNramp5 mutant. The amino acid sequence of the OsNramp5 mutant comprises a sequence as shown in SEQ ID NO. 3 or a sequence as shown in SEQ ID NO. 4. Two OsNramp5 mutants are screened out, the plant height, the effective ear number, the maturing rate and the thousand seed weight of rice containing the OsNramp5 mutants are all superior to those of wild rice, the cadmium content in seeds is remarkably reduced, and gene germplasm resources can be provided for breeding of low-cadmium accumulation rice varieties. 本发明公开了OsNramp5突变体及其相关产品和应用。OsNramp5突变体的氨基酸序列包括如SEQ ID NO.3或如SEQ ID NO.4所示序列。本发明筛选出2种OsNramp5突变体，含有OsNramp5突变体的水稻的株高、有效穗数、结实率、千粒重均优于野生型水稻，且种子中镉含量显著降低，能为低镉积累水稻品种的选育提供基因种质资源。
