chloroplast DNA (cpDNA) have lower rates of nucleotide substitution than the rest of the chloroplast genome. Avail-able DNA sequence data from plants now allow a detailed investigation of the rates of nucleotide substitution in the three plant genomes, reconstruction of the phylogenetic relationships among some higher plants, and comparison of

Evolution of Higher-Plant Chloroplast DNA-Encoded Genes: Implications for Structure-Function and Phylogenetic Studies. Annual Review of Plant Physiology .

Chloroplast DNA, ribosomes, starch granules, and many proteins can be found floating in the stroma. Suspended within the chloroplast stroma is the thylakoid system. Thylakoids are membranous sacks containing chlorophyll molecules and are where the light reactions of photosynthesis happen. In our own bioinformatic analysis of the chloroplast contribution to the rice genome, we found that 778 678 bp of chloroplast DNA were present in fragments greater than 100 bp in the rice genome (Vorster, 2008). This chloroplast DNA was present in >2000 different fragments, of which only 212 were of length greater than 1000 bp. Functional evaluation of a nitrogenase-like protochlorophyllide reductase encoded by the chloroplast DNA of Physcomitrella patens in the cyanobacterium Leptolyngbya boryana.

In addition to this the components of chloroplast participate in several regulatory functions of the cell as well as in photorespiration. 4. Chloroplast Function and Structure. Chloroplasts are very similar to mitochondria, but are found only in the cells of plants and some algae. Like mitochondria, chloroplasts produce food for their cells.

The chloroplast (Gr., chlor=green plast=living) is most widely occurring chromoplast of the plants. It occurs mostly in the green algae and higher plants. The chloroplast contains the pigment chlorophyll a and chlorophyll b and DNA and RNA. They also play important role in plant life activity.

A single chloroplast DNA has a mass of about 80 – 130 million Endosymbiotically originated chloroplast DNA (cpDNA) encodes part of the genetic information needed to fulfill chloroplast function, including fundamental processes such as photosynthesis. Through their role in photosynthesis, whereby carbon dioxide and water are converted into carbohydrates and oxygen, chloroplasts are not only essential for the life of plants but for all life on Earth. Chloroplasts contain their own genome, comprising approximately 130 genes, which are involved in photosynthesis and other important metabolic processes1,2. Chloroplast genomes display Chloroplasts have their own DNA, often abbreviated as cpDNA. It is also known as the plastome when referring to genomes of other plastids. Its existence was first proven in 1962. The first complete chloroplast genome sequences were published in 1986, Nicotiana tabacum (tobacco) by Sugiura and colleagues and Marchantia polymorpha (liverwort) by Ozeki et al.
