As an important characteristic and horticultural crop in China, sweetpotato can be used as food, industrial raw material, vegetable, ornamental material. Purple for table use is rich anthocyanin, which leads to some bitter taste, so it needs further quality improvement. Genetic engineering technology effective method improve traits, but there are few reports on genes that sweetness taste. A xylosidase gene (Ibα-XYL1) was cloned from variety ‘Yanshu 25’ with a fragment size of 2796 bp encoding 932 amino acid sequences. It has typical transmembrane domain three functional domains, localized at cell membrane. Reduction Ibα-XYL1 expression had no significant effect the expansion characteristics anthocyanin content storage root (SPSR), could up-regulate sucrose synthesis related (SuS, SuPS) promote accumulation soluble sugar fresh transgenic SPSR. At same time, starch modifications (GASS, SBE) decomposition (AMY BAM), reduce granule pasting temperature, conversion maltose, increase content, taste steamed The results great significance improvement sweetpotato.
