e0“but also resulted in a dramatic increase in storage protein levels in potato tubers.”
e1“Transformation of Solanum tuberosum, cv. Desiree, with the tomato prosystemin gene, regulated by the 35S cauliflower mosaic virus promoter, resulted in constitutive increase in defensive proteins in potato leaves, similar to its effects in tomato plants, but also resulted in a dramatic increase in storage protein levels in potato tubers. Tubers from selected transformed lines contained 4- to 5-fold increases in proteinase inhibitor I and II proteins, >50% more soluble and dry weight protein, and >50% more total nitrogen and total free amino acids than found in wild-type tubers.”

Other claims from this paper (6)
- Intervention effect Transformation with tomato prosystemin constitutively increased potato leaf defensive proteins.
- Intervention effect Transformed tubers contained 4- to 5-fold more proteinase inhibitor I and II proteins than wild type.
- Intervention effect Transformed tubers had over 50% more soluble and dry weight protein than wild type.
- Intervention effect Transformed tubers had over 50% more total nitrogen and free amino acids than wild type.
- Mechanism The authors infer dual regulation of wound responsive leaf inhibitors and developmental tuber storage proteins by prosystemin.
- Mechanism Potato plants recruit leaf systemin signaling components to regulate storage protein accumulation in tubers.
