Abstract excerpt

Chloroplast biogenesis requires precise coordination between the nuclear and plastid genomes, orchestrated by the plastid-encoded RNA polymerase (PEP) complex. In this study, we characterized a spontaneous albino lethal mutant, XNS106_1, in cucumber. The mutant exhibits complete chlorophyll deficiency and photosynthetic failure, leading to post-germinative lethality. Genetic analysis revealed that the phenotype...
