GeneRIFs: Gene References Into Functions

What's a GeneRIF?
  1. In competition with the Ustilago sucrose transporter, the high sucrose concentration in the phloem appeared disadvantageous for the ZmSUT1, preventing sucrose recovery from the apoplastic space in the fungus/plant interface.
    Title: The fungal UmSrt1 and maize ZmSUT1 sucrose transporters battle for plant sugar resources.
  2. These data indicated that [(18)F]FDS analogs are valuable tools to probe sucrose-SUT interactions and to monitor sucrose transport in plants.
    Title: In vivo transport of three radioactive [(18)F]-fluorinated deoxysucrose analogs by the maize sucrose transporter ZmSUT1.
  3. A model for the dual roles for ZmSut1 function (phloem loading and apoplasmic recycling), Sut1 evolution, and its possible use to enhance Suc export from leaves in engineering C3 grasses for C4 photosynthesis is discussed.
    Title: Sucrose Transporter ZmSut1 Expression and Localization Uncover New Insights into Sucrose Phloem Loading.
  4. Sucrose transporter 1 is expressed in multiple cell types throughout the plant and functions to load sucrose into phloem companion cells, restrict its accumulation in the apoplasm, and prevent its loss during long-distance transport.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
