A major structural component of the cuticle of plants is cutin. Analysis of the function of cutin in vivo has been limited because no mutants with specific defects in cutin have been characterized. Therefore, transgenic Arabidopsis plants were generated that express and secrete a cutinase from Fusarium solani f sp pisi. Arabidopsis plants expressing the cutinase in the...

The coordinated induced expression of ß-oxidation genes is essential to provide the energy supply for germination and postgerminative development. However, very little is known about other functions of ß-oxidation in nonreserve organs. We have identified a gene-specific pattern of induced ß-oxidation gene expression in wounded leaves of Arabidopsis. Mechanical damage triggered the local and...
