Abstract:
Chlorophyll is vital for plants, giving them their green color and playing indispensable crucial role in photosynthesis. Chlorophyll-deficient mutants serve as classic models for studying plant pigment metabolism and typically exhibit chlorotic or albino phenotypes, resulting in major impacts on photosynthetic efficiency and growth development of plants. Understanding the mechanisms behind chlorophyll deficiency not only advances basic plant biology but also supports crop breeding strategies aimed at improving yield, stress tolerance, and adaption. This article provides a comprehensive review of recent research on the molecular mechanisms underlying chlorophyll metabolism, chloroplast structure, photosynthetic systems, relevant transcription factors, and the effects of external environmental factors on chlorophyll-deficient mutants. It provides a theoretical basis for improving plant pigment metabolism and crop breeding.

Plant Metabolism
Sunlight, the primary source of energy in plants, is first absorbed by the chlorophyll pigments present in their leaves. Plants then use this energy to carry out photosynthesis, where water is oxidized into oxygen and carbon dioxide...
Transgenic Plants
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...
