Comparative analysis of de novo genomes reveals dynamic intra-species divergence of NLRs in pepper.

ABSTRACT:

Background

Peppers (Capsicum annuum L.) containing distinct capsaicinoids are the most widely cultivated spices in the world. However, extreme genomic diversity among species represents an obstacle to breeding pepper.

Results

Here, we report de novo genome assemblies of Capsicum annuum 'Early Calwonder (non-pungent, ECW)' and 'Small Fruit (pungent, SF)' along with their annotations. In total, we assembled 2.9 Gb of ECW and SF genome sequences, representing over 91% of the estimated genome sizes. Structural and functional annotation of the two pepper genomes generated about 35,000 protein-coding genes each, of which 93% were assigned putative functions. Comparison between newly and publicly available pepper gene annotations revealed both shared and specific gene content. In a
