Karrikins is a new family of different compounds that can interrupt the seed's dormancy and cause seed germination. Karrikins chemically defined as a family of compounds formed in smoke from the burning of plant material. Previous research indicates that karrikins have essential roles in various biological processes, such as seed dormancy, seed germination, and early plant growth. Recent research indicates that KAR1 can alleviate seed dormancy in rapeseed and Avena fatua by balancing and biosynthesis of gibberellin (GA) and abscisic acid (ABA). This study also summarized the role of KAR1 in affecting ethylene synthesis to resolve seed dormancy by controlling the ACS, ACO, and ethylene receptor genes. Expression levels of ethylene-related genes imply a regulation of the seeds' sensitivity modified to the existence of ethylene and indicate a specific diversification of the particular genes. KAR1 has demonstrated its capacity to regulate the antioxidant activity significantly to break dormancy. KAR1 encouraged the aggregation of 1-aminocyclopropane-1-carboxylic acid (ACC) during ethylene synthesis as a result of increased activity of two ethylene biosynthesis enzymes, ACC synthase (ACS) and ACC oxidase (ACO). Data on the role of KAR1 in alleviating seed dormancy in various plants are hardly available. Only a few articles demonstrated KAR1’s function in alleviating seed dormancy. Researchers have to pay attention on this issue. This analysis can enable researchers to understand KAR1 and how it works.

Karrikins是一系列不同的化合物，它们可以中断种子的休眠并导致种子发芽。Karrikins在化学上定义为燃烧植物材料而在烟雾中形成的一族化合物。先前的研究表明，karrikins在各种生物学过程（例如种子休眠，种子发芽和植物早期生长）中具有重要作用。最近的研究表明，KAR1可以减轻油菜籽和燕麦的休眠。通过赤霉素（GA）和脱落酸（ABA）的平衡和生物合成。这项研究还总结了KAR1在通过控制ACS，ACO和乙烯受体基因影响乙烯合成以解决种子休眠中的作用。乙烯相关基因的表达水平暗示着种子对乙烯存在的敏感性的调节，表明特定基因的特定多样性。KAR1已显示出显着调节抗氧化剂活性以打破休眠的能力。由于两种乙烯生物合成酶ACC合酶（ACS）和ACC氧化酶（ACO）的活性增加，KAR1促进了乙烯合成过程中1-氨基环丙烷-1-羧酸（ACC）的聚集。几乎没有关于KAR1在减轻各种植物的种子休眠中作用的数据。只有很少的文章证明了KAR1在减轻种子休眠中的功能。研究人员必须注意这个问题。这种分析可以使研究人员了解KAR1及其工作原理。
