https://www.selleckchem.com/products/plx8394.html The early light-induced proteins (ELIPs) are postulated to act as transient pigment-binding proteins that protect the chloroplast from photodamage caused by excessive light energy. Desert mosses such as Syntrichia caninervis, that are desiccation-tolerant and homoiochlorophyllous, are often exposed to high-light conditions when both hydrated and dry ELIP transcripts are accumulated in response to dehydration. To gain further insights into ELIP gene function in the moss S. caninervis, two ELIP cDNAs cloned from S. caninervis, ScELIP1 and ScELIP2 and both sequences were used as the basis of a transcript abundance assessment in plants exposed to high-light, UV-A, UV-B, red-light, and blue-light. ScELIPs were expressed separately in an Arabidopsis ELIP mutant Atelip. Transcript abundance for ScELIPs in gametophytes respond to each of the light treatments, in similar but not in identical ways. Ectopic expression of either ScELIPs protected PSII against photoinhibition and stabilized leaf chlorophyll content and thus partially complementing the loss of AtELIP2. Ectopic expression of ScELIPs also complements the germination phenotype of the mutant and improves protection of the photosynthetic apparatus of transgenic Arabidopsis from high-light stress. Our study extends knowledge of bryophyte photoprotection and provides further insight into the molecular mechanisms related to the function of ELIPs.BTG4 is the last cloned and poorly studied member of BTG/Tob family. Studies have suggested that BTG4 is critical for the degradation of maternal mRNAs in mice during the process of maternal-to-zygotic transition, and downregulated in cancers, such as gastric cancer. However, the regulatory mechanism of BTG4 and its function in cancers remain elusive. In this study, we have for the first time identified the promoter region of the human BTG4 gene. Serial luciferase reporter assay demonstrated that the core promoter of BTG4 is mainl
