Coix lacryma-jobi, called also as adlay or Job’s tears, is an annual plant species belonging to the the Andropogoneae tribe in Panicoideae subfamily of the Poaceae family. This plant is widely cultivated in tropical and subtropical regions of the world. C. lacryma-jobi includes many variants, of which C. lacryma-jobi var. ma-yuen has soft shell and has been cultivated as a cereal crop (Chen et al. 2006). In Korea, C. lacryma-jobi var. ma-yuen is also called as Yulmu and has been cultivated as a cereal crop and medicinal plant (Park and Lee 1999; Kim et al. 2000; Lee et al. 2002; RDA 2013). Although several genomic resources have been produced for C. lacryma-jobi, those are still not sufficient for molecular study and breeding for this species, compared to other Panicoideae species such as foxtail millet, maize and sorghum whose genomes were sequenced (Bennetzen et al., 2012; Zhang et al., 2012; Jiao et al., 2017; McCormick et al., 2017). On this account, the adlay genome sequencing project has been initiated in 2018 as a part of National Agricultural Genome Program (NAGP, http://nabic.rda.go.kr/nagp/). The aim of this project is to generate draft genome sequence, genetic map and transcriptome profile of C. lacryma-jobi and then to support comprehensive studies for molecular breeding, biotechnological approach and pharmacological research of this plant species.
