A curated list of InDel markers for rapid genetic mapping in <i>Arabidopsis thaliana</i>

Identification of novel functional genes through mutant analysis is one of the most powerful approaches in plant science. In the model plant Arabidopsis thaliana, this approach typically combines whole-genome sequencing of the mutant with fine mapping using molecular polymorphic markers between two ecotypes to narrow down the genomic region containing the mutant allele. Among PCR-based mapping methods, insertion/deletion (InDel) markers allow for precise and rapid genotyping with relatively simple technology. In this report, we present a set of 49 new InDel markers distributed across the entire genome between Columbia (Col-0) and Landsberg erecta (Ler) accessions, specifically suitable for initial mapping experiments. These markers are designed to detect insertions in Col-0 or deletions in Ler with a length polymorphism greater than 100 bp and will help facilitate map-based gene cloning.
