Abstract

Water lily is an important ornamental flower plant which is capable of viviparous plantlet development. But no study has been reported on the molecular basis of viviparity in water lily. Hence, we performed a comparative transcriptome study between viviparous water lily and a nonviviparous species at four developmental stages. The higher expression of highly conserved AUX/IAA, ARF, GH3, and SAUR gene families in compared to is predicted to have a major impact on the development and evolution of viviparity in water lily. Likewise, differential regulation of hormone signaling, brassinosteroid, photosynthesis, and energy-related pathways in the two species provide clues of their involvement in viviparity phenomenon. This study revealed the complex mechanism of viviparity trait in water lily. The transcriptomic signatures identified are important basis for future breeding and research of viviparity in water lily and other plant species.

摘要

睡莲是一种重要的观赏花卉植物，能够进行胎生苗的发育。但是，关于睡莲胎生的分子基础还没有研究。因此，我们在四个发育阶段对胎生睡莲和非胎生物种进行了比较转录组研究。与非胎生物种相比，胎生睡莲中高度保守的 AUX/IAA、ARF、GH3 和 SAUR 基因家族的高表达，预计对睡莲胎生的发育和进化有重大影响。同样，两种植物中激素信号转导、油菜素内酯、光合作用和与能量相关途径的差异调控为它们参与胎生现象提供了线索。本研究揭示了睡莲胎生特性的复杂机制。鉴定的转录组特征是未来睡莲和其他植物物种胎生研究和育种的重要基础。
