| 英文摘要 | Plants possess multiple homologues of the skp1 gene encoding an essential subunit of the scf ubiquitin ligases, but only ask1 ( arabidopsis skp1-like 1) and ask2 have been characterised genetically. in addition, little is known about the function of skp1 homologues in monocots. here we report on a winter wheat homologue of skp1 named tsk1 ( triticum aestivum skp1-like 1). expression analyses revealed that it was expressed predominantly in young roots and. oral buds. rna in situ hybridisation showed that it was expressed in the shoot apical meristem (sam) and anthers, especially the tapetum and microsporocytes at the time of meiosis. it was also expressed in almost the entire meristematic and elongation zones of the root. these observations indicated that tsk1 might function in dividing cells. the arabidopsis ask1-1 mutant with overexpressed tsk1 driven by the camv 35s promoter exhibited partial fertility, suggesting that tsk1 could partially restore function in meiosis to the ask1-1 mutant. in addition, overexpression of tsk1 in wild type arabidopsis resulted in changes in auxin responses and auxin-related phenotypes, consistent with a role of ask1 in arabidopsis auxin response. these results suggest possible functional conservation between tsk1 and ask1. |
