Webmechanisms of kernel development and silk senescence will provide important information for improving the pollination rate to obtain high maize yields. Results: In this study, transcript profiles were determined in an elite maize inbred line (KA105) to investigate the molecular mechanisms functioning in self-pollinated and unpollinated maize ...
