摘要
为研究与烟草早花有关的基因,本试验利用安捷伦烟草全基因组基因芯片对烤烟品种K326及其抗早花变异系华烟06、K326LF花芽分化过程茎尖端基因表达谱进行分析,筛选出其中与花芽分化可能有主要关系的基因:AGL20、CCR2、ELF4、ERD7、CBF1、COR413-PM1、EMF2、VIP4、COL1、AGL17、COL9、FPA、SWN等,其中COL2、ELF4的表达差异达到了5倍;AGL62、CBF1、SWN、NAP与FPA的差异大于或等于10倍。该试验为进一步研究烟草抗早花机理及培育抗早花新品种提供参考。
To research the gene of premature flowering tobacco, in this study, we used the Agilent Tobacco Oligo Microarray to deduce the expression profiling of flue-cured tobacco K326 and its premature flowering resistance variety Huayan06, K326 LF under the flower bud differentiation process. Through screening, we concluded genes that may have relation with flower bud differentiation were as follows: AGL20、CCR2、ELF4、ERD7、CBF1、COR413-PM1、EMF2、VIP4、COL1、AGL17、COL9、FPA、SWN etc. The expression difference level of COL2 and ELF4 reached 5 times, AGL62、CBF1、SWN、NAP and FPA was greater than or equal to10 times. This study provided a reference for the further study of flue-cured tobacco premature flowering resistance mechanism and premature flowering resistance varieties breeding.
