英文摘要: |
Rice is one of the most important food crops. With the increase of population, the reduction of cultivated
land and the continuous deterioration of environmental conditions, the further increase of yield is still an important goal of
breeders. Increasing biomass by improving photosynthetic efficiency is an important measure to further increase rice yield.
Chloroplast is the main place of photosynthesis and the energy supply center of cells, which is essential for plant growth
and cell metabolism. The identification and cloning of key genes involved in the development and regulation of chloroplasts
and the revelation of their regulatory networks and molecular mechanisms have important scientific significance and
practical value for regulating photosynthesis and plant growth and developing new varieties of rice with high photosynthetic
efficiency. Leaf colors are diverse and easy to be distinguished. Therefore, leaf color mutants are often used as important
materials to explore the mechanism of photosynthesis, chlorophyll biosynthesis, chloroplast structure and function, and
genetic development regulation. Rice leaf color mutants are more common and green-revertible albino mutants are easy to
be distinguished. Green-revertible albino mutants have great application value in the research of chloroplast development, chlorophyll synthesis, photosynthesis efficiency, genetic breeding and other fields. The phenotype, classification, source,
mechanism of action, mode of inheritance and influencing factors of the green-revertible albino mutants were reviewed in order
to provide references for the theoretical research and practical application. |
