Description
Summary:The aim of this study was to explore the molecular mechanisms of induced leaf senescence by preventing pollination in maize using a proteomic method combined with other physiological methods. An elite maize inbred line Yu816 was selected for evaluation of its senescence mechanism. Phenotypic and chlorophyll content analysis revealed that the onset of leaf senescence occurred earlier in non-pollinated (NONPOL) leaves than pollinated (POL) leaves. Leaf protein species of NONPOL and POL leaves were separately extracted and their proteomes were assessed using isobaric tags for relative and absolute quantitation (iTRAQ) analysis. A total of 4371 protein species were identified, of which 809 exhibited differentially altered abundance (P
