Delivering copper within plant cells.
Two genes recently identified in Arabidopsis thaliana may be involved in sequestering free copper ions in the cytoplasm and delivering copper to post-Golgi vesicles. The genes COPPER CHAPERONE and RESPONSIVE TO ANTAGONIST1 are homologous to copper-trafficking genes from yeast and humans. This plant copper-delivery pathway is required to create functional ethylene receptors. The pathway may also...
متن کاملCopper cofactor delivery in plant cells.
Copper (Cu) is a micronutrient that has roles in photosynthesis, respiration, antioxidant activity, cell wall metabolism and hormone perception. Excess Cu is toxic and therefore its delivery has to be tightly regulated. Recent progress in the study of Cu homeostasis has revealed not only components of the Cu delivery machinery but also regulatory systems that control Cu-protein expression and c...
متن کاملPlant copper chaperones.
Copper chaperones, soluble copper-binding proteins, are essential for ensuring proper distribution of copper to cellular compartments and to proteins requiring copper prosthetic groups. They are found in all eukaryotic organisms. Orthologues of the three copper chaperones characterized in yeast, ATX1, CCS and COX17, are present in Arabidopsis thaliana. Plants are faced with unique challenges to...
متن کاملDelivering phonological and phonics training within whole-class teaching.
BACKGROUND Early, intensive phonological awareness and phonics training is widely held to be beneficial for children with poor phonological awareness. However, most studies have delivered this training separately from children's normal whole-class reading lessons. AIMS We examined whether integrating this training into whole class, mixed-ability reading lessons could impact on children with p...
متن کاملDelivering Higher Education Policies within a Challenging Community
The aim of this paper is to examine how the University of Huddersfield embraced the ethos of community cohesion and made moves into a problematic community. Drawing on qualitative research conducted in Oldham in Greater Manchester the paper presents insights into how higher education is viewed in the area. The research reveals that higher education in a deprived community is successful but one ...
