Whole genome sequencing and comparative transcriptome analysis of a novel seawater adapted, salt-resistant rice cultivar - sea rice 86.

ABSTRACT:

Background

Rice (Oryza sativa) is critical for human nutrition worldwide. Due to a growing population, cultivars that produce high yields in high salinity soil are of major importance. Here we describe the discovery and molecular characterization of a novel sea water adapted rice strain, Sea Rice 86 (SR86).

Results

SR86 can produce nutritious grains when grown in high salinity soil. Compared to a salt resistant rice cultivar, Yanfen 47 (YF47), SR86 grows in environments with up to 3X the salt content, and produces grains with significantly higher nutrient content in 12 measured components, including 2.9X calcium and 20X dietary fiber. Whole genome sequencing demonstrated that SR86 is a relatively ancient indica subspecies, phylogenetically close to the divergence point of th
