DcHSP17.7

Gene Details:

DcHSP17.7, a small heat shock protein in carrot, is tissue-specifically expressed under salt stress and confers tolerance to salinity.
Native-PAGE analysis showed that DcHSP17.7 was present in an approximately 250 kDa complex both before and after salt treatment. Salinity reduced bacterial cell viability| however, the transgenic E. coli expressing DcHSP17.7 exhibited a higher survival rate than control E. coli under salt stress.
DcHSP17.7 functioned as a molecular chaperone, increasing the level of soluble proteins. Taken together, DcHSP17.7 appears to play an important role (or roles) in conferring tolerance to thermal stresses in plants.
This suggests that DcHSP17.7 performs molecular chaperone activity in salt-stressed transgenic E. coli. Our results suggest that DcHSP17.7 is likely to be involved in tolerance not only to thermal stresses but also to other abiotic stresses, such as salinity.
We have examined the ability of a carrot (Daucus carota L.) heat shock protein gene encoding HSP17.7 (DcHSP17.7) to confer enhanced heat tolerance to potato (Solanum tuberosum L.), a cool-season crop.
