Abstract

When wheat (Triticum aestivum) seedlings are exposed to a cold temperature (2-4°C) above 0°C, sucrose accumulates and sucrose synthase activity increases. The effect of a cold period on the level of sucrose synthase (SS) was investigated. Using antibodies against wheat germ SS, Western blots studies showed that the amount of the SS peptide increased during 14 days in the cold, when plants were moved from 23°C to 4°C. The level of SS diminished when plants were moved back to 23°C. Northern blots of poly(A)+ RNA, confirmed a five- to sixfold induction of SS in wheat leaves during cold acclimation. These results indicate that SS is involved in the plant response to a chilling stress.
