编码含有NAC结构域的产物的基因，如矮牵牛中的无顶端分生组织（NAM）、拟南芥中的杯形子叶2（CUC2）和NAP，在植物发育中具有重要功能。我们在这里描述的分子方面的OsNAC基因编码的蛋白质与NAC结构域在水稻（Oryza sativa L.）。序列分析表明，植物NAC基因可分为几个亚家族，如NAM，ATAF和OsNAC3亚家族。在水稻中，0sNAC 1和0sNAC 2被归类于NAM亚家族，其包括NAM和CUC 2，而0sNAC 5和0sNAC 6落入ATAF亚家族。除了这些亚家族的成员之外，水稻基因组还包含NAC基因OsNAC3、OsNAC4（均在OsNAC3亚家族中）、OsNAC7和OsNAC8。这些结果和Southern分析表明OsNAC基因在水稻基因组中构成了一个大的基因家族。每个OsNAC基因在不同器官中以特定模式表达，表明该家族在水稻发育中具有多样且重要的作用。
Genes that encode products containing a NAC domain, such as NO APICAL MERISTEM (NAM) in petunia, CUP-SHAPED COTYLEDON2 (CUC2) and NAP in Arabidopsis thaliana, have crucial functions in plant development. We describe here molecular aspects of the OsNAC genes that encode proteins with NAC domains in rice (Oryza sativa L.). Sequence analysis revealed that the NAC genes in plants can be divided into several subfamilies, such as the NAM, ATAF, and OsNAC3 subfamilies. In rice, OsNAC1 and OsNAC2 are classified in the NAM subfamily, which includes NAM and CUC2, while OsNAC5 and OsNAC6 fall into the ATAF subfamily. In addition to the members of these subfamilies, the rice genome contains the NAC genes OsNAC3, OsNAC4 (both in the OsNAC3 subfamily), OsNAC7, and OsNAC8. These results and Southern analysis indicate that the OsNAC genes constitute a large gene family in the rice genome. Each OsNAC gene is expressed in a specific pattern in different organs, suggesting that this family has diverse and important roles in rice development.
