Other claims from this paper (6)
- Intervention effect The transformation raised ADPglucose pyrophosphorylase activity 4-5-fold.
- Intervention effect The increased enzyme activity had no significant effect on the measured nucleotide sugar and phosphate metabolite contents.
- Association Flux from supplied sucrose to starch rose roughly with enzyme activity.
- Observation Flux measurements gave a response coefficient close to 1 for starch synthesis against enzyme activity.
- Observation Transformed tubers with increased starch flux had increased starch turnover.
- Association Increased turnover was associated with greater tuber starch degradation capacity.
