MtN 3/唾液/SWEET型基因，单独存在或存在于一个家族中，存在于从单细胞原生动物到高等真核生物的多种生物中，表明它们在细胞生物中的重要性。这些基因编码多位膜蛋白，其特征在于MtN 3/唾液结构域，也称为PQ环重复。水稻MtN 3/saliva/SWEET基因家族由21个成员组成，是已测序生物中最大的家族之一。越来越多的数据表明，这些基因参与了多种生理过程，包括生殖发育，衰老，环境适应，寄主-病原体相互作用，在不同的物种。在水稻中，该家族的一些成员，包括Xa 13/Os 8 N3/OsSWEET 11，这是生殖发育所必需的，被致病细菌黄单胞菌黄单胞菌所利用。入侵宿主。新出现的数据还显示，至少一些MtN 3/唾液/SWEET型蛋白可以通过与离子转运蛋白相互作用或作为糖转运蛋白促进离子转运来调节不同的生理过程。对MtN 3/唾液/SWEET型基因研究的不断深入将有助于阐明其在不同生物体中功能的分子基础。
The MtN3/saliva/SWEET-type genes, existing either alone or in a family group, are found in diverse organisms, from monocellular protozoa to higher eukaryotes, indicating their importance in cellular organisms. These genes encode polytopic membrane proteins that feature an MtN3/saliva domain, also known as a PQ loop repeat. The rice MtN3/saliva/SWEET gene family consists of 21 members and is among the largest families in sequenced organisms. Accumulating data suggest that these genes are involved in multiple physiological processes, including reproductive development, senescence, environmental adaptation, and host-pathogen interaction, in different species. In rice, some members of the family, including Xa13/Os8N3/OsSWEET11, which is essential for reproductive development, are used by the pathogenic bacterium Xanthomonas oryzae pv. oryzae to invade its host. Emerging data have also revealed that at least some MtN3/saliva/SWEET-type proteins may regulate different physiological processes by facilitating ion transport via interaction with ion transporters or as sugar transporters. The accumulating knowledge about MtN3/saliva/SWEET-type genes will help to elucidate the molecular bases of their function in different organisms.
