资料介绍

摘  要:拟南芥是一种模式植物,在植物学研究中有重要意义。本试验是对拟南芥CS27715(CS25)基因突变体材料进行筛选, 通过育种发芽、提取DNA、PCR扩增和琼脂糖凝胶电泳等步骤筛选突变体,获得了CS25杂合子突变体。对CS25杂合子表型进行了初步形态学观察,结果显示:CS25杂合子突变体植株与野生型植株相比较,突变体植株矮小;叶片少,叶片表皮毛数量少,叶缘全缘;花柄短,花序集中;果荚长短径比值小;种子呈短椭圆型。

Screening of Transposable Elements Insertion Mutant(CS27715)in Arabidopsis and Morphology Observation 
Abstract:Arabidopsis is a pattern of plants and it has a great significance in botany research. In this study, we screened the heterozygous and homozygotes of CS27715 (CS25) heterozygous in Arabidopsis by PCR amplification. Then, with a particular morphology observation, the result showed that CS25 heterozygous mutant plants compared with wild-type plants, mutant plants stunted; leaves small, leaf table fur small, entire leaf edges; flower handles short, inflorescence concentrated; the pod is length ratio of small diameter; seeds are short elliptic.
Keywords: Arabidopsis; Transposon insertion mutation CS25; Screening
