The article "Seed Germination and Vigor" by Loïc Rajjou et al. reviews the complex process of seed germination and the factors that influence it. Seed germination is crucial for plant reproduction and involves the resumption of metabolic activity in the embryo within the seed. The quality of stored messenger RNAs (mRNAs) and proteins during embryo maturation on the mother plant is a key contributor to successful germination. Proteostasis and DNA integrity also play significant roles. The sulfur amino acid metabolism pathway, particularly methionine (Met) metabolism, is highlighted as a critical biochemical determinant of seed germination. The review discusses the importance of stored components, metabolic transitions, and posttranslational modifications in controlling seed germination. It also explores the role of hormones, chemical stimulants, and repair processes in regulating germination. The authors emphasize that germination vigor depends on multiple biochemical and molecular variables, and their characterization can lead to new markers for seed quality in breeding programs and biotechnological approaches to improve crop yields.The article "Seed Germination and Vigor" by Loïc Rajjou et al. reviews the complex process of seed germination and the factors that influence it.
