Abstract

|
To gain a better understanding on the function of the otato Solanum tuberosum Multiprotein Bridging Factor 1 rotein (StMBF1) its interaction with the TATA box inding protein (TBP) was demonstrated. In addition we eported that StMBF1 rescues the yeast mbf1 mutant henotype, indicating its role as a plant co-activator. These ata reinforce the hypothesis that MBF1 function is also onserved among non closely related plant species. In ddition, measurement of StMBF1 protein level by estern blot using anti-StMBF1 antibodies indicated that he protein level increased upon H2O2 and heat shock reatments. However, the potato β-1,3-glucanase protein evel was not changed under the same experimental onditions. These data indicate that StMBF1 participates in the cell stress response against oxidative stress allowing us to suggest that MBF1 genes from different plant groups may share similar functions.
