The development of cysteine proteases in freesia corms during responses to chilling

摘要

Freesia protease (FP)-A has been found in regular freesia corms (Kaneda et al., Biosci. Biotechnol. Biochem. 61 (1997) 1554). New corms were generated from original corms that were kept for several months at 4degreesC. In this study, two proteases (FP-B and FP-C) have been found to new corms kept for 6 months at 4degreesC, and have increased during new corms enlargement.
