摘　　要：以拟南芥突变体rfc3-1为材料,研究了拟南芥复制因子C亚基3(AtRFC3)基因突变对拟南芥植株开花和种子发育的影响。结果表明:RFC3基因突变导致rfc3-1的开花时间比野生型植株提前1周,呈小花表型,且导致种子发育异常。将野生型AtRFC3基因转化到突变体rfc3-1后,恢复了突变株的野生型表型,证实AtRFC3基因在拟南芥花器官和种子发育中起重要作用。Using rfc3-1 mutant as material,the effects of AtRFC3 mutation on flowering and seed development of Arabidopsis thaliana were studied.The results showed that AtRFC3 mutation caused small floral organ phenotype and early flowering for about one week earlier in rfc3-1 mutant than in wild type plants,and led to abnormal seed development.The mutant phenotypes were reverted after transforming wild type AtRFC3 gene into rfc3-1 mutant,suggesting that AtRFC3 plays an essential role in flowering and seed development in Arabidopsis thaliana.
