Gapless reference genome assembly of <i>Didymella glomerata</i>, a new fungal pathogen of maize causing Didymella leaf blight.

ABSTRACT: Didymella leaf blight (DLB) caused by Didymella glomerata is a new fungal disease of maize (Zea mays), first detected in 2021 in Panjin, Liaoning province of China. Here we report the reference genome assembly of D. glomerata to unravel how the fungal pathogen controls its virulence on maize at the molecular level. A maize-infecting strain Pj-2 of the pathogen was sequenced on the Illumina NovaSeq 6000 and PacBio Sequel II platforms at a 575-fold genomic coverage. The 33.17 Mb gapless genome assembly comprises 32 scaffolds with L/N₅₀ of 11/1.36 Mb, four of which represent full-length chromosomes. The Pj-2 genome is predicted to contain 10,334 protein-coding genes, of which 211, 12 and 134 encode effector candidates, secondary metabolite backbone-forming enzy
