Exploring the origin of a unique mutant allele in twin-tail goldfish using CRISPR/Cas9 mutants
Published 2024-04-01“…Here, we performed genetic crossing with twin-tail ornamental goldfish and CRISPR/Cas9-mutated goldfish to investigate why only a single mutated allele—chdS with a E127X stop codon (also called chdA E127X )—gives rise to the twin-tail phenotype in the modern domesticated goldfish population. …”

The pentatricopeptide repeat protein EMP601 functions in maize seed development by affecting RNA editing of mitochondrial transcript ccmC
Published 2023-10-01“…A single-nucleotide deletion in the emp601 mutant caused a frameshift and introduced a premature stop codon into the predicted EMP601. This mutation was associated with reduced accumulation of mitochondrial complex III as well as with inhibition of growth and differentiation of basal endosperm transfer layer cells, leading to final degeneration of the embryo and endosperm. …”
