花朵形态是一种受复杂网络调节的现象,是荷花重要的观赏特征之一。花瓣状的雄蕊在荷花中非常普遍。然而,这种现象背后的机制仍然不清楚。在这里,通过 RNA-seq 对花瓣、雄蕊花瓣和雄蕊进行了比较转录组分析。通过两两比较分析,大量涉及激素信号转导途径和转录因子的基因,特别是MADS-box基因,被鉴定为莲花雄蕊花瓣状的候选基因。总而言之,这些结果提供了对莲花花器官发育和雄蕊花瓣的分子网络的深入了解。本文的在线版本 (10.1186/s12864-018-4950-0) 包含补充材料,可供授权用户使用。
Flower morphology, a phenomenon regulated by a complex network, is one of the vital ornamental features in Nelumbo nucifera. Stamen petaloid is very prevalent in lotus flowers. However, the mechanism underlying this phenomenon is still obscure. Here, the comparative transcriptomic analysis was performed among petal, stamen petaloid and stamen through RNA-seq. Using pairwise comparison analysis, a large number of genes involved in hormonal signal transduction pathways and transcription factors, especially the MADS-box genes, were identified as candidate genes for stamen petaloid in lotus. Taken together, these results provide an insight into the molecular networks underlying lotus floral organ development and stamen petaloid.
