Comparison of high-light effects with and without methyl viologen indicate barley chlorina mutants exhibit contrasting sensitivities depending on the specific nature of the chlorina mutation: Comparison of wild-type, chlorophyll b-less clo f2 and light-sensitive, xhlorophyllb-deficient clo f104 mutants

Peng, Chang Lian; Gilmore, Adam

Description

This study compared the response to methyl viologen (MV)-induced photooxidation in wild-type barley (wt), and both its chlorina f104-nuclear gene mutant (that restricts Chl a and b synthesis) and its f2-nuclear gene mutant (that inhibits all Chl b synthesis). Without MV, the f2 mutant showed the highest sensitivity to high light, with Fv/Fm being reduced by 80% after 80 min of irradiation. There was little difference in response to high light without MV between f104 and wt. After vacuum...[Show more]
