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. |
