Abstract: Degradation of the thylakoid membrane is the first step for chloroplast breakdown during leaf senescence and is masked by increase number and size of plastoglobuli Plastoglobuli consist of an outer galactolipid monolayer studded with PAP-fibrillin on the surface of plastoglobuli PAP-fibrillin suggested playing roles in maintaining the structural stability of plastoglobuli metabolite transport and against biotic and abiotic stresses We are interested in dissecting the regulatory network of PAP-fibrillin genes in response to developmental and environmental signals during leaf senescence in Arabidopsis We have analyzed expression profiles of 14 PAP-fibrillin genes during different stages of leaf development and senescence Most of these genes were induced to high levels of expression in early leaf development and then reduced to low levels as leaf developed to maturity These genes then again induced to high levels during onset of leaf senescence We have also analyzed the expression profiles of these genes in response to different abiotic stresses and hormonal treatments Promoter analysis for these family genes we have identified 40 putative transcription factors and 17 of these were induced during senescence The putative regulatory networks of PAP-fibrillin gene family in response to developmental and environmental signals are discussed
