Complete Genome Sequences of Septoria linicola: A Resource for Studying a Damaging Flax Pathogen

Abstract

Fungal genus Septoria causes diseases in a wide range of plants. Here, we report the first genome sequences of two strains of Septoria linicola, the causal agent of the pasmo disease of flax (Linum usitatissimum). The genome of the first strain, SE15195, was fully assembled in 16 chromosomes, while 35 unitigs were obtained for a second strain, SE14017. Structural annotations predicted 13,096 and 13,085 protein-encoding genes and transposable elements content of 19.0 and 18.1% of the genome for SE15195 and SE14017, respectively. The four smaller chromosomes 13 to 16 show genomics features of potential accessory chromosomes. The assembly of these two genomes is a new resource for studying S. linicola and improving management of pasmo. [Graphic: see text] Copyright © 2022 The Author(s).
