Gene Details:

• Gene ID: Soltu.DM.02G022370.1
• Gene Symbol: StTST3.1
• Gene Name: TST3-type isoform
• Genome:
• Species: Solanum tuberosum

Functional Descriptions:

• Suppression of the tonoplast sugar transporter, StTST3.1, affects transitory starch turnover and plant growth in potato.
• Found that suppressing StTST3.1 resulted in growth retardation and pale green leaves in potato plants. StTST3.1-silenced plants displayed abnormal chloroplasts and impaired photosynthetic performance.
• The subcellular localization assay and the oscillation expression patterns revealed that StTST3.1 encoded a tonoplast-localized protein and responded to photoperiod.
• Transient overexpression of StNOL accelerated chlorophyll b degradation in tobacco leaves. Our results indicated that StTST3.1 is involved in transitory starch turnover and chlorophyll metabolism, thereby playing a critical role in normal potato plant growth.
• StTST3.1-silenced plants exhibit a starch excess phenotype and accumulate maltose.
