Abstract

<abstract abstract-type="main"> <title> <x xml:space="preserve">Abstract</x> </title> <p>Seed germination that begins with imbibition and ends with radicle emergence is the first step for plant growth. Successful germination is not only crucial for seedling establishment but also important for crop yield. After being dispersed from mother plant, seed undergoes continuous desiccation in ecosystem and selects proper environment to trigger germination. Owing to the contribution of transcriptomic, proteomic, and molecular biological studies, molecular aspect of seed germination is elucidated well in <italic>Arabidopsis</italic>. Recently, more and more proteomic and genetic studies concerning cereal seed germination were performed on rice (<italic>Oryza sativa</italic>) and barley (<italic>Hordeum vulgare</italic>), which possess completely different seed structure and domestication background with <italic>Arabidopsis</italic>. In this review, both the common features and the distinct mechanisms of seed germination are compared among different plant species including <italic>Arabidopsis</italic>, rice, and maize. These features include morphological changes, cell and its related structure recovery, metabolic activation, hormone behavior, and transcription and translation activation. This review will provide more comprehensive insights into the molecular mechanisms of seed germination.</p> </abstract>
