Subsequently co-opted to describe the sequencing and analysis of molecules (from nucleic acids to proteins), bioinformatics has diverse applications including the analysis, visualization, storage, and generation of data relating to living organisms and the molecular information they carry. Plant biology has reaped dividends from the development and maturation of bioinformatics; it has not only extended our understanding of model plant species such as &lt;i&gt;Arabidopsis thaliana&lt;/i&gt; (Cantó-Pastor et al., &lt;span&gt;2021&lt;/span&gt;) but also driven innovative solutions to characterize non-model species (Nevado et al., &lt;span&gt;2014&lt;/span&gt;). Both avenues of discovery contribute to key objectives in improving food security, conservation, and biotechnology.&lt;/p&gt;&lt;p&gt;The size and complexity of many plant genomes has historically made their analysis financially and computationally difficult. Frequent polyploidy and repeat element expansion make the elucidation of plant genome sequences challenging (Soltis et al., &lt;span&gt;2015&lt;/span&gt;). Furthermore, high heterozygosity in wild populations, pervasive hybridization, and a lack of inbred lines present roadblocks to analyses such as read mapping and assembly (Kajitani et al., &lt;span&gt;2019&lt;/span&gt;). Long-read technologies have become ever more accessible in recent years, and algorithmic advances have accommodated sequential updates to error models, read lengths, and library types (Michael and VanBuren, &lt;span&gt;2020&lt;/span&gt;). Moreover, novel methods to scaffold contigs and obtain long-range interaction information have driven impressive improvements in genome assembly quality, making telomere-to-telomere genome sequencing projects an achievable goal for many labs (Kress et al., &lt;span&gt;2022&lt;/span&gt;).&lt;/p&gt;&lt;p&gt;Long-read technologies paired with novel mapping algorithms have fueled discovery of new transposable element (TE) dynamics, and there has been an associated resurgence of interest in their role in adaptive trait evolution and phenotypic variation (Schrader and Schmitz, &lt;span&gt;2019&lt;/span&gt;; Pimpinelli and Piacentini, &lt;span&gt;2020&lt;/span&gt;). Bioinformatics developments in this field have led to vast improvements in our ability to detect complex TE mobilization patterns such as nested insertions and structural variants (Bree et al., &lt;span&gt;2022&lt;/span&gt;; Lemay et al., &lt;span&gt;2022&lt;/span&gt;).
