Characterization of T-DNA Insertional Mutant of Formaldehyde-Responsive Protein 1

摘要

Formaldehyde responsive protein(FRP) 1 belongs to the family of universal stress protein(USP) and is known to respond to stress caused by fumigation of gaseous volatile organic compounds(VOCs) such as formaldehyde and toluene. However, the molecular function of this protein is not well understood at cellular and molecular level. In this study, loss of function mutant of FRP1 generated by T-DNA insertion(/r/?7-4) has been isolated from Arabidopsis thaliana and the function of FRP1 was characterized. The loss-of-function mutant of FRP1 appeared slight growth defects with shorter stem and rosette leaves compared to wild type. In addition, the damage caused by exogenous VOCs was more severe in frpl-4 than in control. Therefore, Arabidopsis FRP1 seems tobe the protein involved not only in the growth and development of plant but also the stress resistance against toxic volatile organic compounds.
