In maize (Zea mays L.), chloroplast development progresses from the basal meristem to the mature leaf tip, and light is required for maturation to photosynthetic competence. During chloroplast greening, it was found that chloroplast DNA (cpDNA) is extensively degraded, falling to undetectable levels in many individual chloroplasts for three maize cultivars, as well as Zea mexicana (the ancestor of cultivated maize) and the perennial species Zea diploperennis. In dark-grown maize seedlings, the… CONTINUE READING
