Abstract

The functions of a large number of genes, including gene families with domains of unknown functions (DUF), still remain unclear. In this study, we analyzed four members of OsDUF1664 (OsDUF1664.1-OsDUF1664.4) in rice Nipponbare. By phylogenetic analysis, DUF1664 members in rice and Arabidopsis were classified into three major groups (I, II, III). Under drought conditions, the expression level of OsDUF1664.3 in rice was significantly elevated. Overexpression of OsDUF1664.3 in Escherichia coli led to a significant enhancement of catalase (CAT) and peroxidase (POD) activities, and improved bacterial resistance to drought. The results of this study will provide important information for further study of the function of the OsDUF1664 family in rice.

水稻OsDUF1664家族的分子特征及功能分析

摘要

大量基因的功能,包括具有未知功能域(DUF)的基因家族,仍不清楚。在本研究中,我们分析了日本晴水稻中 OsDUF1664 的四个成员(OsDUF1664.1-OsDUF1664.4)。通过系统发育分析,水稻和拟南芥中的DUF1664 成员被分为三大类(I、II、III)。干旱条件下,水稻中OsDUF1664.3的表达水平显着升高。OsDUF1664.3大肠杆菌中的表达导致过氧化氢酶 (CAT) 和过氧化物酶 (POD) 活性的显着增强,并提高了细菌对干旱的抗性。本研究结果将为进一步研究OsDUF1664家族在水稻中的功能提供重要信息。
