Abstract:    Zea nicaraguensis, a wild relative of cultivated maize (Zea mays subsp. mays), is considered to be a valuable germplasm to improve the waterlogging tolerance of cultivated maize. Use of reverse genetic-based gene cloning and function verification to discover waterlogging tolerance genes in Z. nicaraguensis is currently impractical, because little gene sequence information for Z. nicaraguensis is available in public databases. In this study, Z. nicaraguensis seedlings were subjected to simulated waterlogging stress and total RNAs were isolated from roots stressed and non-stressed controls. In total, 80 mol L–1 Illumina 100-bp paired-end reads were generated. De novo assembly of the reads generated 81 002 final non-redundant contigs, from which 5 261 full-length transcripts were identified. Among these full-length transcripts, 3 169 had at least one Gene Ontology (GO) annotation, 2 354 received cluster of orthologous groups (COG) terms, and 1 992 were assigned a Kyoto encyclopedia of genes and genomes (KEGG) Orthology number. These sequence data represent a valuable resource for identification of Z. nicaraguensis genes involved in waterlogging response.
