摘要:
为研究蓝光对夏菊生长发育的影响,并探究光质影响菊花生长发育的分子机制,选用菊花优香 [Chrysanthemum morflorium (Ramat.) Kitam.‘ Yuuka’]为试验材料,应用植物组织培养技术,经蓝光照射组培苗后,对组培苗进行表型观察、叶绿素含量测定、石蜡切片制作及相关基因表达量分析,进而从表观、细胞、分子3个层面来观察蓝光照射对菊花的影响。结果表明,在组培苗生长前期,蓝光处理会抑制菊花根的发育,而在后期该抑制作用减弱;同时蓝光照射会使植株发生矮化,且叶片明显变小,但植株总叶片数并未改变。基于石蜡切片的结果显示,蓝光处理60 d后,植株较白光对照组,茎明显变细,根变粗,叶片中栅栏细胞明显变大;同时,在叶绿素含量方面,蓝光照射对叶绿素含量的影响并不明显;而在基因表达水平上,蓝光处理会使光敏色素基因CmPHYA、CmPHYB、CmPHYC和隐花色素基因CmCRY1、CmCRY2的表达量升高,使CmCRY1.2的表达量下降。另外,蓝光处理对开花调控基因CmCO的表达没有明显影响,但能诱导开花素基因CmFT1、CmFT2、CmFT3的表达。
