A sucrose transporter, LjSUT4, is up-regulated during Lotus japonicus nodule development
LjSUT4, encoding a putative sucrose transporter, was identified in a Lotus japonicus nodule cDNA library. The deduced amino acid sequence showed a high degree of identity with sucrose transporters from other plants. Semi-quantitative RT-PCR analysis demonstrated that the L. japonicus SUT4 gene was e...

| Zusammenfassung: | LjSUT4, encoding a putative sucrose transporter, was identified in a Lotus japonicus nodule cDNA library. The deduced amino acid sequence showed a high degree of identity with sucrose transporters from other plants. Semi-quantitative RT-PCR analysis demonstrated that the L. japonicus SUT4 gene was expressed at high levels in both roots and nodules. In situ hybridization revealed that, in young nodules, SUT4 mRNA transcripts are present in vascular bundles, inner cortex and both infected and uninfected cells while, in mature nodules, accumulation of transcripts was restricted only in vascular bundles and the inner cortex. The results indicated that LjSUT4 codes for a putative sucrose transporter, and its expression pattern suggests a possible shift in the mechanism of sugar transport during nodule development. The role of this polypeptide in sucrose transport and metabolism is discussed |
