Transposons, as mobile genetic elements in the genome, play a crucial role in genetic innovation and genome reconstruction of rice. Structural variation (including deletion, duplication, inversion, and translocation) greatly alters the genome structure and function, thereby affecting the phenotypic characteristics of rice and its ability to adapt to the environment. Both of them have important contributions to rice seed breeding. In this study, we reviewed the effects of transposon and structural variation on the adaptability and diversity of Oryza species, and discussed in detail how these genetic variants promote the adaptability and biodiversity of Oryza species by altering gene expression, regulating physiological and biochemical pathways, and adapting to environmental stress. Technical challenges and advances in studying the role of transposons and structural variation in rice were also discussed, and potential applications of these genetic mechanisms in future rice breeding and ecological conservation were pointed out. Through a systematic analysis of the existing literature, this study highlights the importance of understanding the role of these genetic elements in the adaptation and diversification of rice, and provides references for future research directions.
