Gene Details:

• Gene ID:
• Gene Symbol: CsSUT1
• Gene Name: Sucrose Transporter 1
• Genome: Cucumis sativus ASM407v2
• Species: Cucumis sativus

Functional Descriptions:

• Down-regulation of the Sucrose Transporter CsSUT1 Causes Male Sterility by Altering Carbohydrate Supply.
• CsSUT1 is expressed in male flowers and encodes a protein that is localized primarily in the tapetum, pollen, and companion cells of the phloem of sepals, petals, filaments, and pedicel.
• This reduction in CsSUT1 expression gave rise to a decline in sugar metabolism, a reduction in expression of transport-related genes, and altered sugar and auxin signaling, and the up-regulation of the expression of several MYB transcription factors.
• Our findings demonstrate that male sterility can be induced by RNAi-mediated down-regulation of CsSUT1 expression, through the resultant perturbation in carbohydrate delivery and subsequent alteration in sugar and hormone signaling and up-regulation of specific MYB transcription factors.
