B73dek55-1MutationIn the dek55-1 mutant, nucleotide C was replaced with nucleotide T at + 449 bp, resulting in the substitution of the amino acid serine (Ser) with phenylalanine (Phe).Recessive; HeterozygousThe dek55-1 kernels were smaller and presented a whitish pericarp, and they could be distinguished from the wild-type (WT) kernels at 15 days after pollination (DAP). At maturity, the dek55-1 kernels were much smaller and shrivelled. To further determine the mutant phenotype, both WT and dek55-1 kernels were longitudinally sliced at 15 DAP. Compared to the WT kernels, the mutant kernels had a small, soft endosperm. Furthermore, compared with the WT kernels, the dek55-1 kernels contained a smaller mature embryo and a reduced proportion of hard endosperm. In addition, the weight of dek55-1 kernel was approximately 70% lower than that of WT kernels. No dek55-1 seeds (0/100) germinated under field conditions, implying that embryo arrest is lethal in the mutants.To further investigate the developmental structure of dek55-1 kernels, we examined the kernel tissue structure of the WT and dek55-1 mutant at 12 and 18 DAP. At 12 DAP, the dek55-1 embryo had only a small scutellum whose development was arrested at the coleoptile stage and a large interspace between the endosperm and the seed coat. In contrast, the WT embryo contained a visible coleoptile, a shoot apical meristem, a scutellum, and two leaf primordia, and the kernel was filled with endosperm cells. At 18 DAP, the WT embryo had developed complete structures, including four leaf primordia, a shoot apical meristem, and a clearly visible root apical meristem, while the dek55-1 embryos presented only a single leaf primordium. In addition, fewer starch grains accumulated in the dek55-1 endosperm cells than in the WT endosperm cells at this stage, and a cavity was observed in the dek55-1 endosperm. Taken together, these results indicate that developmental defects in the embryo and endosperm had occurred in the dek55-1 mutant.Ear15 DAPDirect sequencing of reverse transcription-polymerase chain29.70%LowDecreased33297963

At maturity, the dek55-1 kernels were much smaller and shrivelled. To further determine the mutant phenotype, both WT and dek55-1 kernels were longitudinally sliced at 15 DAP. Compared to the WT kernels, the mutant kernels had a small, soft endosperm. Furthermore, compared with the WT kernels, the dek55-1 kernels contained a smaller mature embryo and a reduced proportion of hard endosperm. In addition, the weight of dek55-1 kernel was approximately 70% lower than that of WT kernels. No dek55-1 seeds (0/100) germinated under field conditions, implying that embryo arrest is lethal in the mutants.To further investigate the developmental structure of dek55-1 kernels, we examined the kernel tissue structure of the WT and dek55-1 mutant at 12 and 18 DAP. At 12 DAP, the dek55-1 embryo had only a small scutellum whose development was arrested at the coleoptile stage and a large interspace between the endosperm and the seed coat. In contrast, the WT embryo contained a visible coleoptile, a shoot apical meristem, a scutellum, and two leaf primordia, and the kernel was filled with endosperm cells.

At maturity, the dek55-1 kernels were much smaller and shrivelled. To further determine the mutant phenotype, both WT and dek55-1 kernels were longitudinally sliced at 15 DAP. Compared to the WT kernels, the mutant kernels had a small, soft endosperm. Furthermore, compared with the WT kernels, the dek55-1 kernels contained a smaller mature embryo and a reduced proportion of hard endosperm. In addition, the weight of dek55-1 kernel was approximately 70% lower than that of WT kernels. No dek55-1 seeds (0/100) germinated under field conditions, implying that embryo arrest is lethal in the mutants.To further investigate the developmental structure of dek55-1 kernels, we examined the kernel tissue structure of the WT and dek55-1 mutant at 12 and 18 DAP. At 12 DAP, the dek55-1 embryo had only a small scutellum whose development was arrested at the coleoptile stage and a large interspace between the endosperm and the seed coat. In contrast, the WT embryo contained a visible coleoptile, a shoot apical meristem, a scutellum, and two leaf primordia, and the kernel was filled with endosperm cells. At 18 DAP, the WT embryo had developed complete structures, including four leaf primordia, a shoot apical meristem, and a clearly visible root apical meristem, while the dek55-1 embryos presented only a single leaf primordium. In addition, fewer starch grains accumulated in the dek55-1 endosperm cells than in the WT endosperm cells at this stage, and a cavity was observed in the dek55-1 endosperm.

B73dek55-1MutationIn the dek55-1 mutant, nucleotide C was replaced with nucleotide T at + 449 bp, resulting in the substitution of the amino acid serine (Ser) with phenylalanine (Phe).Recessive; HeterozygousThe dek55-1 kernels were smaller and presented a whitish pericarp, and they could be distinguished from the wild-type (WT) kernels at 15 days after pollination (DAP). At maturity, the dek55-1 kernels were much smaller and shrivelled. To further determine the mutant phenotype, both WT and dek55-1 kernels were longitudinally sliced at 15 DAP. Compared to the WT kernels, the mutant kernels had a small, soft endosperm. Furthermore, compared with the WT kernels, the dek55-1 kernels contained a smaller mature embryo and a reduced proportion of hard endosperm. In addition, the weight of dek55-1 kernel was approximately 70% lower than that of WT kernels. No dek55-1 seeds (0/100) germinated under field conditions, implying that embryo arrest is lethal in the mutants.To further investigate the developmental structure of dek55-1 kernels, we examined the kernel tissue structure of the WT and dek55-1 mutant at 12 and 18 DAP. At 12 DAP, the dek55-1 embryo had only a small scutellum whose development was arrested at the coleoptile stage and a large interspace between the endosperm and the seed coat. In contrast, the WT embryo contained a visible coleoptile, a shoot apical meristem, a scutellum, and two leaf primordia, and the kernel was filled with endosperm cells. At 18 DAP, the WT embryo had developed complete structures, including four leaf primordia, a shoot apical meristem, and a clearly visible root apical meristem, while the dek55-1 embryos presented only a single leaf primordium. In addition, fewer starch grains accumulated in the dek55-1 endosperm cells than in the WT endosperm cells at this stage, and a cavity was observed in the dek55-1 endosperm. Taken together, these results indicate that developmental defects in the embryo and endosperm had occurred in the dek55-1 mutant.Ear15 DAPThe strand- and transcript-specific RNA sequencing (STS-PCRs68.71%HighIncreased33297963
