Abstract

The plant-specific transcription factor family YABBY plays important roles in plant responses to biotic and abiotic stresses. Although the function of YABBY has been identified in many species, systematic analysis in lotus () is still relatively lacking. The present study aimed to characterize all of the genes in lotus and obtain better insights into in response to salt stress by depending on ABA signaling. Here, we identified nine genes by searching the whole lotus genome based on the conserved YABBY domain. Further analysis showed that these members were distributed on six different chromosomes and named from to , which were divided into five subgroups, including YAB1, YAB2, YAB5, INO, and CRC. The analysis of -elements in promotors revealed that could be involved in plant hormone signaling and plant responses to abiotic stresses. Quantitative real-time PCR (qRT-PCR) showed that could be up-regulated or down-regulated by ABA, fluridone, and salt treatment. Subcellular localization indicated that NnYABBY4, NnYABBY5, and NnYABBY6 were mainly localized in the cell membrane and cytoplasm. In addition, the intrinsic -activity of NnYABBY was tested by a Y2H assay, which revealed that NnYABBY4, NnYABBY5, and NnYABBY6 are deprived of such a property. This study provided a theoretical basis and reference for the functional research of YABBY for the molecular breeding of lotus.

摘要

植物特异性转录因子家族YABBY在植物对生物和非生物胁迫的响应中发挥重要作用。尽管YABBY的功能已在许多物种中得到鉴定，但在莲（）中的系统分析仍然相对缺乏。本研究旨在鉴定莲中的所有基因，并通过依赖脱落酸（ABA）信号通路，更好地了解其对盐胁迫的响应。在此，我们基于保守的YABBY结构域搜索整个莲基因组，鉴定出9个基因。进一步分析表明，这些成员分布在6条不同的染色体上，从命名到，分为5个亚组，包括YAB1、YAB2、YAB5、INO和CRC。对启动子中元件的分析表明，可能参与植物激素信号传导和植物对非生物胁迫的响应。实时定量PCR（qRT-PCR）表明，ABA、氟啶酮和盐处理可上调或下调其表达。亚细胞定位表明，NnYABBY4、NnYABBY5和NnYABBY6主要定位于细胞膜和细胞质中。此外，通过酵母双杂交试验检测了NnYABBY的内在活性，结果表明NnYABBY4、NnYABBY5和NnYABBY6不具有这种特性。本研究为莲分子育种中YABBY功能研究提供了理论依据和参考。
