Abstract: The sweetpotato cultivar Quick Sweet (QS) with a lower pasting temperature of starch is a unique breeding material, but the biochemical background of this property has been unknown. To assess the physiological impact of the reduced isoform II activity of starch synthase (SSII) on the starch properties in sweetpotato storage root, transgenic sweetpotato plants with reduced expressions of the SSII gene were generated and evaluated. All of the starches from transgenic plants showed lower pasting temperatures and … Show more

“…Most of the investigations made so far have concentrated the analyses on the composition of amylose in the starch granules [19][20][21][22][23][24] and the composition of unit chains in the amylopectin component [19][20][21][22][23][24][25][26][27][28]. A few studies have also focussed on the internal unit chain composition, i.e.…”

“…In sweet potato, several genes that encode the starch biosynthetic enzymes have been cloned and characterized 13, 14, 2327 . These genes have been reported to impact the starch composition, structure and physicochemical properties and minimally influence the starch content.…”

“…We selected two sweetpotato (I. batatas) cultivars, WS and W71, as representative genotypes, exhibiting white and orange tuberous roots (tubers), respectively, since they have also been used in Agrobacterium tumefaciensmediated transformation ( [13,14], and our unpublished results). Carotenoid pigments were extracted from the two cultivars and subjected to HPLC-PDA-HRMS analysis.…”

“…Total RNA was isolated from 100 mg of leaf powder from each cultivar, as described [14]. Total RNA extracts were then treated with DNase I to remove any contaminating genomic or foreign DNA.…”
