Effective ecological restoration of abandoned agricultural fields, especially highly degraded ecosystems, remains challenge. Germination is imperative to restore natural ecosystems and save the environment. Low germination rate is key player to disturb the ecosystem. During germination, seeds undergo physiological and morphological changes. Starting with imbibition, seeds consume stored food and biosynthesize different proteins. Afterward, radical emergence leads to the seedling establishment. Coordinated activities during seed germination correspond directly with transcription of genes playing crucial roles. Despite the presence of rigid seed coats, up/down-regulation of some genes coding specific proteins require thorough investigation. We have focused topical advancements in transcriptomics with reference to seed germination. Over the years model plant species such as Oryza sativa and Arabidopsis thaliana have been analyzed through transcriptomic studies with respect to seed germination. A daunting challenge is to provide detailed transcriptomic profiling of germination process in woody plants. So far there is a shortage of transcriptomics data regarding woody plants. Cyclobalnopsis gilva is a woody plant having very low seed germination and no transcriptomics analysis has been conducted. Omics technology can offer increments to existing information about C. gilva seed germination. The review aims to reveal the involvement of molecular biological mechanisms during seed germination and their effects on ecology. It will be helpful to solve low germination problem of all over the world woody plants to save forest ecology.
