红果番茄GF基因位点的绿果肉(green-flesh,gf)突变体有gf、gf2、gf3、gf4、gf5共5种等位基因,因其特殊的果实颜色而受到大众喜爱.笔者调查发现,gf位点突变体具有抗番茄褪绿病毒病的功能,但有些棕果番茄并不是gf位点突变体.从300份候选材料中选取6份棕果番茄材料,并以易感褪绿病毒的番茄红果材料‘T2015-47’为对照,以gf位点特异引物进行检测.试验结果表明,‘T2016-33’不能酶切出109 bp和57 bp的特异条带,为gf基因突变体;‘2012-2’酶切出187 bp和171 bp的特异条带,为gf2基因突变体;‘T2015-66’和‘12016-32’酶切出216 bp和18 bp的特异条带,为gf4基因突变体.建立了利用分子标记快速准确鉴定出棕果番茄是否为gf位点突变体的方法,为选育抗褪绿病毒的棕果番茄品种提供了辅助手段.
Molecular screen for gf gene in six brown tomato varieties
There are five mutant genes including gf,gf2,gf3,gf4,gf5 for GF allele.The mutant gene result in red tomato turn into green and brown tomato.The brown tomatoes is one of the most favored fruits by people for its special fruit colour.Our latest research showed that gf mutant gene was strongly resistant to Tomato Chlorosis Virus (ToCV).In order to establish rapid molecular screen method for gf gene,6 brown tomato varities were chosen from 300 candidates as materials and the red tomato ‘2015-47’ was used as control.The result showed that none of 109 bp and 57 bp specific bands were digested for varity ‘T2016-33’ that was gf mutant;a187 bp and a 171 bp specific bands were amplified for varity ‘2012-2’ that was gf 2mutan;a 216 bp and a 18 bp specific bands were amplified for‘T2015-66’ and ‘T2016-32’that were gf4 mutant.In this experiment we established a rapid and exact method to identify the gf mutant gene that accelerate brown tomato breeding.
