Abstract：
Circular RNA (circRNA) is a type of non-coding RNA with multiple biological functions. Whole circRNA genomes in plants have been identified, and circRNAs have been demonstrated to be widely present and highly expressed in various plant tissues and organs. CircRNAs are highly stable and conserved in plants, and exhibit tissue specificity and developmental stage specificity. CircRNAs often interact with other biomolecules, such as miRNAs and proteins, thereby regulating gene expression, interfering with gene function, and affecting plant growth and development or response to environmental stress. CircRNAs are less studied in plants than in animals, and their regulatory mechanisms of biogenesis and molecular functions are not fully understood. A variety of circRNAs in plants are involved in regulating growth and development and responding to environmental stress. This review focuses on the biogenesis and regulatory mechanisms of circRNAs, as well as their biological functions during growth, development, and stress responses in plants, including a discussion of plant circRNA research prospects. Understanding the generation and regulatory mechanisms of circRNAs is a challenging but important topic in the field of circRNAs in plants, as it can provide insights into plant life activities and their response mechanisms to biotic or abiotic stresses as well as new strategies for plant molecular breeding and pest control.
摘要：
环状RNA(circularRNA,circRNA)是一类具有多种生物学功能的非编码RNA。植物中的整个circRNA基因组已经被鉴定，和circRNAs已被证明在各种植物组织和器官中广泛存在并高度表达。CircRNAs在植物中高度稳定和保守，并表现出组织特异性和发育阶段特异性。CircRNAs经常与其他生物分子相互作用，如miRNA和蛋白质，从而调节基因表达，干扰基因功能，影响植物生长发育或对环境胁迫的反应。与动物相比，CircRNAs在植物中的研究较少，它们对生物发生和分子功能的调节机制还没有完全理解。植物中的各种circRNAs参与调节生长发育和响应环境胁迫。这篇综述集中在circRNAs的生物发生和调控机制。以及它们在生长过程中的生物学功能，发展,和植物的应激反应，包括对植物circRNA研究前景的讨论。了解circRNAs的产生和调控机制是植物中circRNAs领域中一个具有挑战性但重要的课题。因为它可以提供有关植物生命活动及其对生物或非生物胁迫的响应机制的见解，以及植物分子育种和病虫害防治的新策略。
