The DELAY OF GERMINATION1 (DOG1) family genes (DFGs) in Arabidopsis thaliana are involved in seed dormancy, reserve accumulation, and desiccation tolerance. Decoding the molecular evolution of DFGs is key to understanding how these seed programs evolved. This article demonstrates that DFGs have diverged in the four lineages DOG1, DOG1‐LIKE4 (DOGL4), DOGL5 and DOGL6, whereas DOGL1, DOGL2 and DOGL3 arose separately within the DOG1 lineage. The systematic DFG nomenclature proposed in this article addresses the current issues of inconsistent DFG annotation and highlights DFG genomic synteny in angiosperms. DFG pseudogenes, or collapsed coding sequences, hidden in the genomes of early‐diverging angiosperms are documented here. They suggest ancient birth and loss of DFGs over the course of angiosperm evolution. The proposed models suggest that the origin of DFG diversification dates back to the most recent common ancestor of living angiosperms. The presence of a single form of DFG in nonflowering plants is discussed. Phylogenetic analysis of gymnosperm, lycophyte, and liverwort DFGs and similar genes found in mosses and algae suggests that DFGs diverged from the TGACG motif‐binding transcription factor genes before the divergence of the bryophyte lineage.

古代和最近的基因复制是种子成熟调节因子的进化驱动力DELAY OF GERMINATION1家族基因

该GERMINATION1的DELAY（DOG1）基因家族（DFG在S）拟南芥参与种子休眠，储备积累和抗旱性。解码DFG的分子进化是了解这些种子程序如何进化的关键。本文演示了DFG S IN四个谱系分道扬镳DOG1，DOG1样4（DOGL4），DOGL5和DOGL6，而DOGL1，DOGL2和DOGL3的范围内分别出现了DOG1血统。系统的本文提出的DFG命名法解决了当前DFG注释不一致的问题，并强调了被子植物中DFG的基因组一致性。隐藏在早期分化被子植物基因组中的DFG假基因或折叠的编码序列已在此处记录。他们暗示了被子植物进化过程中DFG的古老诞生和丧失。提出的模型表明，DFG多样化的起源可以追溯到最近的活被子植物的共同祖先。讨论了非开花植物中单一形式DFG的存在。裸子植物，苔藓植物和艾蒿DFG的系统发育分析S和类似的基因发现苔藓和藻类表明，DFG ■从分歧TGACG序结合转录因子苔藓血统的分歧之前的基因。
