1. Soluble beta-fructofuranosidases were purified 16-fold from French-bean-pod extracts and 35-fold from potato-tuber extracts. 2. The two enzymes had similar overall properties but differed from each other quantitatively in lability and reaction kinetics. 3. A non-diffusible inhibitor of
An invertase cDNA (Ibbetafruct1) was cloned from sweet potato leaves and characterized. The deduced amino acid sequence of the Ibbetafruct1-encoded protein was closely related to vacuolar invertases and included the WECVD catalytic domain characteristic of them. An expression plasmid containing the
Potato (Solanum tuberosum L.) vacuolar invertase (β-fructofuranosidase; EC 3.2.1.26) inhibitor 2 (StInvInh2) plays an important role in cold-induced sweetening (CIS) of potato tubers. The transcript levels of StInvInh2 were increased by prolonged cold in potato tubers with CIS-resistance but
Potato vacuolar acid invertase (StvacINV1) (β-fructofuranosidase; EC 3.2.1.26) has been confirmed to play an important role in cold-induced sweetening of potato tubers. However, the transcriptional regulation mechanisms of StvacINV1 are largely unknown. In this study, the 5'-flanking sequence of
Male-sterile plants are used in hybrid breeding as well as for gene confinement for genetically modified plants in field trials and agricultural production. Apart from naturally occurring mutations leading to male sterility, biotechnology has added new possibilities for obtaining male-sterile
