N2 - Transposable elements (TEs) have long been considered junk DNA; however, the availability of genome sequences and the growth of omics databases have accelerated the study of TEs, and they are now considered evolutionary signatures. TEs, essential genetic elements in plant genomes, can move around the genome by either “cut-paste” (DNA transposons) or “copypaste” mechanisms (RNA transposons). TEs often affect host genome size and interact with host genes, resulting in altered gene expression and regulatory networks. Several genes have been identified to be influenced/modified by the action of TEs. TEs have diverse structures and functions. Plants are capable of using TEs as promoters and enhancers to drive epigenetic mechanisms in a tissue-specific manner. However, our knowledge about TEs remains poor despite extensive research in plants. Plant physiological functions associated with TEs have been challenging to analyse due to a lack of focused research. Another limitation is the lack of sufficient genetic information. The different functions displayed by plant genomes are genetically regulated, which opens up opportunities in areas such as genomic evolution and epigenetic modification. Indeed, understanding the contribution of TEs in the plant genome is indispensable to assess the diversity of evolutionary adaptability in plant taxa. In this study, we review the applications of TEs and discuss the value of genetic information in the plant genome. Genomic information about TEs has a significant value in high throughput research, including forward and reverse genetics. We discuss current strategies in using TEs for the genetic dissection of plant genomes. This review covers opportunities to use different TEs databases to increase the productivity of economically important plants for sustainable development.
