摘要/Abstract

摘要： 转录水平的变化是转录因子功能发挥的重要体现形式,高通量测序技术的发展和应用揭示了丰富的转录数据,对转录数据的深度分析有助于基因的注释和功能研究。本文以水稻WRKY转录因子家族为对象,在总结WRKY基因功能的基础上,对生物和非生物胁迫、发育、营养和激素处理等不同生物学过程中的转录数据进行了系统的整理和挖掘,获得了不同反应中转录变化的特定WRKY基因清单,丰富了水稻WRKY转录因子家族成员的注释信息,以期这些信息为后续的功能研究提供有价值的参考。

Abstract: Transcription factors regulate alteration of transcription levels. Recently, huge amount of transcriptomic data are accumulated via the application of high throughput sequencing technology, and it is reasonable to postulate that in-depth analysis of transcription data could be used to enhance gene annotation. In this study, we chose the gene family of rice WRKY transcription factors. Based on literature search, the transcriptional data under different biological processes, including biotic and abiotic stress, development, and nutrient absorption and hormone treatments were analyzed systematically. To the end, we summarize the list of differentially expressed WRKY genes. We also expect that such information will enrich their functional annotation and also provide direct clues for subsequent functional studies.

Key words: WRKY transcription factor, transcriptional feature, rice, annotation, transgenic plants
