Abstract

In vitro, under conditions mimicking those found in plant cell walls, in vivo, hydroxyl radicals (OH) are readily generated and cause non-enzymic scission wall polysaccharides. Production of apoplastic OH is potentially a mechanism of wall loosening, important in cell expansion, fruit ripening etc. This project will test the hypothesis that apoplastic OH radicals are generated in vivo. A membrane-nonpermeant 'trap' molecule will be developed that in the presence of apoplastic OH liberates tritiated water, which can be quantified. Using this trapping' system, diverse plant tissues (believed to be undergoing wall loosening) will be surveyed for production of apoplastic OH.
