Genetic studies of seed maturation regulators, combining transcriptomics and network analysis, suggest the significance of genetic diversification for maturation programs, particularly in seed plants. By contrast, analogs of the maturation programs, such as dormancy and desiccation tolerance, are also found in non-seed plants. It is thus conceivable that seeds recalled or renovated ancient programs of stress-induced growth arrest that were already present in ferns, bryophytes, and possibly in algae. This opinion article discusses the origins and genetic diversification of the abscisic acid (ABA)-dependent seed maturation programs by addressing questions provoked by recent findings about the DELAY OF GERMINATION1 (DOG1) family proteins, which regulate reserve accumulation, dormancy, and/or desiccation tolerance in seeds in a gene-specific or redundant manner.

种子成熟调节因子的遗传学研究，结合转录组学和网络分析，表明遗传多样性对于成熟程序（特别是种子植物）的重要性。相反，在非种子植物中也发现了成熟程序的类似物，例如休眠和脱水耐性。因此，可以想象到，在蕨类植物，苔藓植物和可能在藻类中已经存在的种子，可以追溯或改良古老的胁迫诱导生长停滞方案。这篇评论文章通过解决由最近发现的有关DELAY OF GERMINATION1（DOG1）家族蛋白引起的问题来讨论脱落酸（ABA）依赖性种子成熟程序的起源和遗传多样性，该蛋白调节储备积累，休眠，
