Phototropin is a blue light receptor, which mediates a variety of blue-light elicited physiological processes in plants and algae. In higher plants these processes include phototropism, chloroplast movement and stomatal opening. In the green alga Chlamydomonas reinhardtii, phototropin plays a vital role in progression of the sexual life cycle and in the control of the eye spot size and light sensitivity Phototropin is also involved in blue-light mediated changes in the synthesis of chlorophylls, carotenoids, chlorophyll binding proteins. We compared the transcriptome of phototropin knock out (PHOT KO) mutant and wild-type parent to analyze differences in gene expression in high light grown cultures (500 μmol photons m−2 s−1). Our results indicate the up-regulation of genes involved in photosynthetic electron transport chain, carbon fixation pathway, starch, lipid, and cell cycle control genes. With respect to photosynthetic electron transport genes, genes encoding proteins of the cytochrome b6f and ATP synthase complex were up regulated potentially facilitating proton-coupled electron transfer. In addition genes involved in limiting steps in the Calvin cycle Ribulose-1,5-bisphosphate carboxylase / oxygenase (RuBisCO), Sidoheptulose 1,7 bisphosphatase (SBPase), Glyceraldehyde-3-phosphate dehydrogenase (3PGDH) and that mediate cell-cycle control (CDK) were also up regulated along with starch synthase and fatty acid biosynthesis genes involved in starch and lipid synthesis. In addition, transmission electron micrographs show increased accumulation of starch granules in PHOT mutant compared to wild type, which is consistent with the higher expression of starch synthase genes. Collectively, the altered patterns of gene expression in the PHOT mutants were associated with a two-fold increase in growth and biomass accumulation compared to wild type when grown in environmental photobioreactors (Phenometrics) that simulate a pond environment. In conclusion, our studies suggest that phototropin may be a master gene regulator that suppresses rapid cell growth and promotes gametogenesis and sexual recombination in wild type strains.

The invention relates to health products with hypolipemic function and also relates to a preparation method for the health products and the usage thereof. The health products comprise active constituents of hongqu powder, hawthorn extract, ginkgo biloba leaf extract, obtuseleaf senna seed extract and radix salviae miltiorrhizae extract. The active constituents have very obvious synergistic effect, thus playing a positive role in hypolipemic in many aspects such as reducing endogenous lipid synthesis, promoting the transfer and excretion of lipid, regulating lipid metabolism and the like, having obvious hypolipemic effect; safety toxicity test proves that the active constituents are safe, innoxious and harmless.

The invention discloses a citrate transporter and its application in lipid synthesis, belonging to the technical fields of genetic engineering and microbial engineering. The citrate-ketoglutarate transporter of the present invention whose amino acid sequence is shown in SEQ ID No.1 has the function of promoting fatty acid production by microorganisms, and the recombinant Mortierella alpina containing the citrate-ketoglutarate transporter of the present invention will be After 7 days of culture on a shaking table, the fatty acid content of Mortierella alpina containing the citric acid-ketoglutarate transporter of the present invention can reach 36.1% of the dry cell weight, which is lower than that of the Mortierella alpina that does not contain the citric acid-ketoglutarate transporter of the present invention. The fatty acid content of Mortierella alpina increased by 30.4%. The present invention improves the lipid synthesis and accumulation capacity of oleaginous microorganisms such as Mortierella alpina at the genetic level by means of genetic engineering, and at the same time ensures the normal growth of oleaginous microorganisms, thereby providing technical support for more efficient industrial production of microbial oils .
