Plant peptide gamma-zein for delivery of biomolecules into plant cells

A method of introducing a molecule of interest into a plant cell having a cell wall includes interacting a gamma-zein peptide with a molecule of interest to form a gamma-zein linked structure. The gamma-zein linked structure is then placed in contact with the plant cell having a cell wall, and allowing uptake of the gamma-zein linked structure into the plant cell. Alternatively, a gene of interest can be expressed in a plant cell having an intact cell wall by interacting a gamma-zein peptide with the gene of interest to form a gamma-zein linked gene structure, allowing uptake of the gamma-zein linked gene structure into the plant cell, and expressing the gene of interest in the plant cell and its progeny.

Method of determining at least one variable of a WDM optical network

A method of optimizing a WDM optical ring network configuration using a genetic algorithm. Preferably, the method includes the steps of initially defining one or more parameters for a WDM optical network or portion of a WDM optical network and creating a plurality of parents each having a gene structure corresponding to the one or more parameters of the WDM optical network or portion thereof. The parents are then ranked according to predetermined fitness criteria. The highest ranking parents are then mated to form one or more children. Preferably, the children are then optionally mutated before or after testing to ensure that they satisfy predetermined network demands. Suitable children replace lower ranking parents to form new parents. The process is then repeated by mating the highest ranking parent in an effort to further optimize the network. Various steps in the genetic algorithm can be repeated until an optimal design is achieved.

Gene sequence of Chinese cabbage dehydration transcription factor BpDREB1 and application thereof

The invention relates to a DREB transcription factor-BpDREB1 (EF219470). The overall length of a gene sequence is 647bp. A coding protein is predicted to contain 213 amino acids, the relative molecular weight of the protein is 23kDa and the theoretical isoelectric point of the protein is 5.11. The sequence homology of BpDREB1 and the transcription factors in the Chinese cabbage is 94%. An evolutionary tree shows that BpDREB1 belongs to the A1 subtribe in the DREB subfamily. The inducible expression mode analysis of the gene shows that BpDREB1 is subjected to intense and rapid inducible expression at low temperature, has response to drought stress to a certain extent but hardly has response to high salinity treatment. After transgenic arabidopsis thaliana over-expressing BpDREB1 is inducedat low temperature, the contents of soluble sugar and proline in arabidopsis thaliana are substantially increased. The above results show that the transcription factor BpDREB1 has the characteristicsof family member gene structures and plays an important role in a low-temperature and drought response pathway.
