Arabidopsis	At5g20280	Plays a major role in photosynthetic sucrose synthesis by catalyzing the rate-limiting step of sucrose biosynthesis from UDP- glucose and fructose- 6-phosphate.	Decrease in leaf sucrose synthesis leads to increased leaf starch turnover and decreased RuBP regeneration-limited photosynthesis but not Rubisco-limited photosynthesis in Arabidopsis null mutants of SPSA1.; 2011; DOI: 10.1111/j.1365-3040.2010.02265.x; PMID: 21309792; https://pubmed.ncbi.nlm.nih.gov/21309792/
