Indels are less commonly used compared to SNPs, although they are relatively abundant along the genome. While SNPs are point mutations, Indels can concern a single base or a longer DNA sequence. A large proportion of eukaryotic genomes is made of transposable elements (TEs), particularly in C. canephora, where the estimated proportion is over 50%. Structural variation, referring to Indels, duplications, interchromosomal/intrachromosomal translocations, and inversions that occur in approximately 50 bp or larger, is another type of molecular marker that can only be efficiently detected using whole-genome sequencing. Some of them are mediated by TEs. Molecular markers potentially possess great information that has not been uncovered yet because of current limitations in mining and analysis tools. specialized 076AMEPLA04 Ramakrishna A. ed. edt IRD Giridhar P. ed. edt IRD Jeszka-Skowron M. ed. edt IRD 213-219 Boca Raton (USA) CRC Press New York (USA) Abingdon 2023 https://www.documentation.ird.fr/hor/fdi:010087093 10.1201/9781003043133-20 978-0-367-48843-7 [F B010087093] https://www.documentation.ird.fr/hor/fdi:010087093 https://www.documentation.ird.fr/intranet/publi/2023-06/010087093.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2023-01-16 2025-02-24 fdi:010087093 fre
