| 英文摘要 | Sand rice (Agriophyllum squarrosum), a diploid Amaranthaceae species within the order Caryophyllalles, has potential as a crop in response to concerns about ongoing climate change and future food security. Modifying the weedy traits, such as dense trichomes, is important for the domestication of sand rice. In this study, an ethyl methanesulfonate (EMS) induced Agriophyllum squarrosum trichomeless mutant (astcl1) was isolated and genetic analysis revealed that this mutant was controlled by a single recessive locus. RNA sequencing was employed to analyze sequence variations between the mutant and wild-type individuals based on allele frequencies. Synteny-based mapping against two closely related and sequenced species finally delimited the causal mutations into an approximately 18.97 mega base pair (Mb) interval on the top portion of the chromosome 6 (Bv6) of sugar beet (Beta vulgaris) and two intervals (5.56 and 2.69 Mb) on the chromosomes 14 (CqA14) and 6 (CqB06) of quinoa (Chenopodium quinoa). These two quinoa intervals were located in the orthologous chromosomal regions against sugar beet Bv6. Differential expression analysis revealed that the astcl1 mutation only affects the expression of a small subset of genes. Most significantly, 17 lipid transport and metabolism related genes, such as GDSL esterases and very-long-chain 3-oxoacyl-CoA reductase 1, and two R2R3 MYB genes, MYB39 and RAX3, were down-regulated in astcl1 mutants. These results imply that the Astcl1 protein coordinately regulates trichome initiation and cuticle biosynthesis in sand rice. |
