Special Issue Information

Dear Colleagues,

The genetic basis and regulatory mechanism of seed dormancy and germination have been a fundamental scientific problem in botany research. In agricultural production, strong dormancy will lead to a low germination rate and uneven emergence. In contrast, weak dormancy will trigger pre-harvest sprouting, reducing the yield and quality of seeds. Hence, coordinating the dormancy and germination of seeds is a primary industrial requirement for agricultural production. In the past decades, significant progress has uncovered the signalling pathways by which seed germination or dormancy are controlled, especially under adverse conditions, such as low temperature, drought, salinity, etc. However, the molecular basis of seed germination and dormancy still needs in-depth study, which would fine-tune crop seeds' dormancy and germination to improve grain quality and yield. The goal of this Special Issue, "Molecular Basis of Seed Germination and Dormancy" in Biology, is to provide an overview of the latest research and discoveries in the regulation of seed germination and dormancy, including cloning novel genes, as well as the potential utilization of biotechnologies. We welcome all types of submissions, including original research, reviews, and methodologies in this field, including (but not limited to) research covering: 

  • Signaling pathway regulating seed germination or dormancy;
  • Morphology or physiology involved in germination or dormancy;
  • The role of phytohormones controlling seed germination or dormancy;
  • Novel metabolites affecting seed germination or dormancy.

Drought stress constitutes a major challenge to wheat production. Melatonin plays a vital role in plants’ resistance to drought stress. Nevertheless, the influence of melatonin seed coating on the drought resistance ability of wheat remains unclear. Hence, in this study, wheat (Yunmai 112) was chosen as the experimental material. The research results indicated that 100 µM exogenous melatonin treatment enhanced the germination rate of wheat seeds by 11% compared to the CK group. Melatonin seed coating (100 or 200 µM) significantly inhibited the accumulation of ROS in wheat seedlings under drought stress conditions and facilitated the growth of wheat seedlings. Then, 100 µM melatonin seed coating elevated the activity of antioxidant enzymes (CAT, Cu/Zn-SOD, POD, and T-GSH) in wheat seedlings and strengthened the resistance of wheat to drought stress. In contrast to the control, 100 or 200 µM melatonin seed coating significantly raised the contents of soluble protein and chlorophyll in wheat seedlings. Further studies demonstrated that 100 µM melatonin seed coating promoted the increase in the thousand-grain weight and yield of wheat under drought stress. Taking together, melatonin seed coating is an effective approach for enhancing the stress resistance and the yield of wheat under drought stress. Full article
