Cloned(Commentary)

Cloned (Comment) Organism
hairpin structure is cloned into Binary plasmid, plants are transformed via Agrobacterium tumefaciens Arabidopsis thaliana

Protein Variants

Protein Variants Comment Organism
additional information a hair-pin construct is activated in the chlorophyll synthase gene in veins and cells neighboring veins, photosynthesis is reduced in these cells, growth and fitness of the plants are compromised Arabidopsis thaliana

Inhibitors

Inhibitors Comment Organism Structure
additional information hairpin structure in plasmid is tran-activated by the yeast transcription factor that is active in veins of leaves and petiols leads to post-transcriptional silencing of the enzyme by RNA interference Arabidopsis thaliana

General Information

General Information Comment Organism
malfunction gene silencing in vein cells and neighboring cells reduces chlorophyll accumulation around veins by 60-90%, CO2 fixation by minor veins from the xylem stream and the amount of specific metabolites such as soluble sugars associated with carbohydrate metabolism and the shikimate pathway are reduced, the abundance of transcripts encoding components of phosphoenolpyruvate generating pathways are altered, leaf senescence, growth rate, and seed size are reduced Arabidopsis thaliana
