Study Notes
Cell-Penetrating Peptides
- Protein vehicles show promise for enhancing DNA transformation in algae by facilitating the penetration of nucleic acids into cells and their integration into the genome.
- Protein molecules can assist in DNA transformation through non-covalent interactions with DNA structures.
- Cell-penetrating peptides (CPPs) are small peptides commonly used for DNA transformation.
- CPPs are the most widely used among different cell-penetrating compounds.
Chalcone Synthesis Limitations
- Prolonged reaction times, harsh conditions, toxic reagents, low selectivity, and low yields are drawbacks of conventional chalcone synthesis methods.
Novel Approach to Chalcone Synthesis
- Involves incorporating the chalcone synthase (CHS) gene from Petunia hybrida into microalga Chlamydomonas reinhardtii using genetic engineering.
- Enhancing stress conditions to induce the phenylpropanoid pathway increases chalcone yield.
- Genetic transformation is facilitated through biolistic gun in C. reinhardtii protoplasts.
Applications of Biolistic Gun
- Revolutionizes plant genetic modification, particularly in crops resistant to conventional methods, enhancing traits like pest resistance and yield.
- Enables precise gene delivery into neuronal cells, advancing research on brain function and disorders.
- Facilitates transient gene expression studies, aiding in understanding gene functions and cellular processes.
- Delivers therapeutic genes for gene therapy and DNA vaccination, and studies cancer biology.
- Allows tissue-specific gene delivery, contributing to research on organ development and diseases.
- Manipulates gene expression to unravel gene functions and regulatory networks in functional genomics.
CHS Gene Transfer through Biolistic Method
- Transfers CHS gene into C. reinhardtii for efficient chalcone production.
- Particle bombardment facilitates gene transfer, enabling the microalgae to biosynthesize chalcone.
Advantages of Biolistic Method
- Easy to use, fast, and versatile.
- Not limited to host specificity or specific species.
- Enables transient and stable expression.
- Only requires small amounts of nucleic acids and few cells.
- Can transfect many cell types, including non-dividing cells and plants.
- Avoids using viruses or potentially toxic chemicals.
- Facilitates gene silencing with large DNA fragments or small interfering RNAs.
