Abstract

BACKGROUND

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.

RESULTS

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.

CONCLUSIONS

Taken together, these results provide an insight into the molecular networks underlying lotus floral organ development and stamen petaloid.

摘要

背景

花形态是由复杂网络调控的现象，是荷花重要的观赏特征之一。莲瓣化雄蕊在荷花中很常见。然而，这一现象的机制尚不清楚。

结果

本研究通过 RNA-seq 对花瓣、莲瓣化雄蕊和雄蕊进行了比较转录组分析。通过两两比较分析，鉴定到大量参与激素信号转导途径和转录因子的基因，特别是 MADS-box 基因，这些基因被认为是荷花莲瓣化雄蕊的候选基因。

结论

综上所述，这些结果为荷花花器官发育和莲瓣化雄蕊的分子网络提供了新的见解。
