Abstract: The use of wild plant species or their halophytic relatives has been considered in plant breeding programs to improve salt and drought tolerance in crop plants. Aeluropus littoralis serves as halophyte model for identification and isolation of novel stress adaptation genes. A. littoralis was described as perennial monocot grass with an estimated small haploid genome of 349 Mb. A. littoralis is using the C4 mechanism for carbon fixation. A. littoralis grows in damp or arid areas, often salt-impregnated places and waste land in cultivated areas. A. littoralis can survive where the water salinity is periodically high and tolerate high salt concentrations in the soil up to 1100 mM sodium chloride. Therefore A. littoralis serves as valuable genetic resource to understand molecular mechanisms of stress-responses in monocots. The knowledge can potentially be used for improving tolerance to abiotic stresses in economically important crops. Several morphological, anatomical, ecological, and physiological traits of A. littoralis have been investigated so far and also the transfer of stress related genes to other species resulted in enhanced stress resistance. Meanwhile, a number of ESTs (expressed sequence tag), genes and promoters induced by the salt and drought stresses were isolated, sequenced and annotated at a molecular level. Here we describe the genome sequence and structure of A. littoralis analyzed by whole genome sequencing and histological analysis. We hope that the publication of the genomic information will support the functional investigation and application of novel genes improving stress resistance in crop plants. Here the assembled contigs and the predicted genes and their respective aminoacid sequences are presented. The A. littoralis de novo sequence was constructed using CLC assembly cell version 4.3.Gene prediction was done with GeMoMa using gene models of Brachypodium distachyon (Brachypodium_distachyon_v3.0, INSDC Assembly GCA_000005505.4, Feb 2018), Oryza sativa (IRGSP-1.0, INSDC Assembly GCA_001433935.1, Oct 2015) and Sorghum bicolor (Sorghum_bicolor_NCBIv3, INSDC Assembly GCA_000003195.3, Apr 2017).
