The invention discloses a method for converting a carbon source into ethylene glycol. The method comprises the following steps: providing a plastid, wherein the plastid comprises gene sequences of SEQ ID NO: 1, SEQ ID NO: 2, SEQ ID NO: 3, SEQ ID NO: 4, SEQ ID NO: 5 and SEQ ID NO: 6; implanting the plastid into blue-green bacteria by means of electroporation treatment to obtain modified blue-green bacteria; and providing the carbon source to the modified cyanobacteria, so that the modified cyanobacteria converts the carbon source into ethylene glycol, thereby producing chemicals with high economic value while treating the carbon-containing waste gas.

Compositions and methods for introducing targeted mutations into the plastid genome are provided.

The invention relates to liver-targeted lycopene plastid pellets and application thereof, the problems that lycopene is poor in water solubility, easy to oxidize and degrade and the like can be solved through the nanoscale structure of plastid membranes wrapping lycopene of the plastid pellets, and the liver-targeted lycopene plastid pellets serve as a natural delivery system. The plastid pellets can improve the water solubility of lycopene and the resistance to ions, acid, heat and other conditions, have good gastrointestinal stability and intestinal permeability, can effectively deliver lycopene to blood and liver and improve the bioavailability of lycopene, and can be applied to the fields of biological medicine, functional food and the like. In addition, the plastid pellets are derived from natural edible plant tissues, can meet the pursuit of consumers on health without side effects, and have wide development prospects.

This invention relates to methods of producing exogenous collagen in photosynthetic organelles and photosynthetic organisms, in particular methods of producing exogenous collagen in the plastid of an alga or plant, particularly in chloroplasts. Genetically altered algae and genetically altered plants, plant parts thereof or plant cells which express collagen in their chloroplasts are also included.

The invention discloses a genetic transformation method of erigeron breviscapus chloroplast. According to the method, plasmids containing target genes are introduced into explants prepared from erigeron breviscapus leaves through a gene gun method, and erigeron breviscapus transfection plants are obtained; wherein the parameters of the gene gun bombardment are as follows: the plasmid DNA concentration is 1-1.5 [mu] g / [mu] l, the number of bombardment times is 1-2, the target distance is 3-9 cm, the bombardment pressure is 900-1100 psi, and the vacuum degree is 26-28 mmHg. By adopting the method established by the invention, the homogenized erigeron breviscapus transfection plant can be efficiently obtained. The method has an important application value.

A method of expressing an agronomically or non-agronomically beneficial trait in a plant plastid comprising expressing an exogenous nucleic acid in the plant to produce non-photosynthetic mutant plants, and using callus grown from the mutant plants as recipients for introduction of a construct having a functional copy of the mutated gene and a gene conferring an agronomically or non-agronomically beneficial trait. Embodiments provide for mutations in chloroplast-encoded genes, as well as mutations in nuclear-encoded genes targeted to the chloroplast that are required for photosynthesis, plants and plant parts produced from such methods, as well as kits for performing the methods as described.
