Project description:The coordination of chloroplast and nuclear genome status are critical for plant cell function, but the mechanism remain largely unclear. In this study, we report that Arabidopsis thaliana CHLOROPLAST AND NUCLEUS DUAL-LOCALIZED PROTEIN 1 (CND1) maintains genome stability in both the chloroplast and the nucleus.
Project description:A microarray analysis was conducted using the brain, heart, and liver tissues of mouse orally administrated aqueous extracts of Ephedra herba, in which the expression level of many genes were altered depending on the duration of treatment time. Aqueous extracts of Ephedra herba were administered orally for 1 hr, 6 hrs, 12 hrs, 24 hrs, 3 days, 5 days and 10 days on mice.

Project description:A microarray analysis was conducted using the brain tissue of mouse orally administrated aqueous extracts of Ephedra herba, in which the expression level of many genes were altered depending on the duration of treatment time. In particular, temporal changes in the expressions of genes can be classified into two major reciprocal patterns. Aqueous extracts of Ephedra herba were administered orally at dosage of 50 or 1,250 mg/kg once daily for 1, 3 and 10 consecutive days on mice. Expression level of genes from brain tissue was compared to that from untreated control mice.

Project description:The regulator for chloroplast biogenesis (rcb) mutant was identified as a mutant defective in phytochrome-mediated chloroplast biogenesis. The rcb mutant has long hypocotyl and albino phenotypes. RCB initiates chloroplast biogenesis in the nucleus by promoting the degradation of the master repressors for chloroplast biogenesis, the PIFs (Phytochrome Interacting Factors). To understand how RCB regulates the expression of PIF-regulated genes, we performed genome-wide expression analysis of RCB-dependent genes using a rcb-10 null allele.
