The molecular and metabolic events behind different germination stages of rice seeds: A metabolomics perspective

Abstract

Seed germination is a crucial stage for the completion of plants' life cycle. The process of seed germination is a very important phenomenon for agricultural food and crop production and to understand the underlying food chemistry. Rice (Oryza sativa L.) being easy to grow and cheap source of phytonutrients is a fundamental food crop across the world. Several researches are going on for years to improve the production of rice, ameliorate the deadly bacterial or fungal diseases utilizing genetics, transcriptomics, and proteomics aspects. Metabolomics is a very new arena of research in this field. With the help of modern-day metabolomic tools and technologies, researchers are incessantly trying to unveil the metabolic construction of rice seeds, and new to this topic is seed germination. The principal aim of this review on metabolomics of germinating rice seeds is to have a big picture on the key molecular, cellular, and metabolic events of germination. This review tries to summarize all the available data to fulfill the aforesaid aim.
