ABSTRACT:
Introducing sucrose phosphorylase activity into plants by transformation with a gene for the enzyme increases the rate of sucrose hydrolysis, leading to increased starch, oil, and protein levels. The preferred gene is from Streptococcus mutans. Surprisingly, in potatoes transformed to express this gene in tubers, reduced bruise discoloration susceptibility and increased uniformity of starch deposition throughout the tuber are achieved.
