Identification of a Chlorophyll-Deficient Mutant in Maize Associated with Exogenous Vector Insertion.

ABSTRACT: Leaf color mutants are commonly characterized by altered chlorophyll content and aberrant chloroplast development, making them valuable models for investigating photosynthetic mechanisms and chloroplast biogenesis. In this study, an albino mutant was isolated from a population of transgenic maize breeding lines. Genetic analysis indicated that the mutant phenotype is inherited in a Mendelian manner and is controlled by a single nuclear locus. This was supported by a χ² test performed on the T₂ generation, which confirmed a segregation ratio consistent with 3:1 (176:68, χ² = 1.07 < χ²_0.05 = 3.84, p > 0.05). Microscopic examination revealed the absence of normally developed chloroplasts in mutant cells. Furthe
