    摘要: The present invention relates to the genetic control of parasites and pathogens via the expression of silencing RNA in transgenic plants, including microalgae. In one aspect, the invention exploits the ability of plants to express the silencing RNA in a form within chloroplasts that is efficiently taken up, after ingestion where it can act to suppress the expression of target genes within the pathogen or parasite.

    摘要: Genetically engineered algae strains for biofuels and bioproduct production have improved iron utilization including iron uptake and storage, and exhibit improved growth characteristics, magnetic separation, and magnetic hysteresis induced cell lysis. Pond production algal strain embodiments with high iron scavenging capabilities limit iron availability to contaminating microorganisms and invading species. Accumulation of high iron and other paramagnetic elements content in the form of ferritin enhances the cells magnetic susceptibility improving efficiency of magnetic separation and magnetic hysteresis induced cell lysis. Several genes of the embodiments are capable of improving iron acquisition including the ferritin gene fer1, iron transport gene fea1, and iron reductase gene fre1. Other genes which improve growth in the high iron conditions permitting higher accumulation of iron include radical scavenging enzymes such as superoxide dismutase, peroxidase, catalase, glutathione peroxidase and the Ferritin like DPR/DPS genes which also bind iron and protect DNA from reactive oxygen species.

    摘要: The present invention is to a safe, biodegradable trace metal binding system that effectively delivers chromium, cobalt, copper, iron, manganese, molybdenum, selenium and zinc to animals. The method of preparing an animal foodstuff composition involves the steps of: providing transgenic algal cells comprising a nucleotide sequence, the nucleotide sequence being capable of expressing a non-native metal-binding protein in the transgenic algal cells; binding the metal-binding protein with at least one metal so as to produce a metal-bound adduct of the metal-binding protein; and admixing the metal-bound adduct with animal foodstuff. The invention is also to a animal foodstuff composition comprising animal foodstuff and transgenic algal cells expressing a non-native metal-binding protein in the transgenic algal cells, such that the transgenic algal cells contain the metal-binding protein and the metal-binding protein being bound to a metal.
