Conserved Cu-MicroRNAs in Arabidopsis thaliana Function in Copper Economy under Deficiency
Copper (Cu) is a micronutrient for plants.Three small RNAs, which are up-regulated by Cu deficiency and target transcripts for Cu Military UAV proteins, are among the most conserved microRNAs in plants.It was hypothesized that these Cu-microRNAs help save Cu for the most essential Cu-proteins under deficiency.Testing this hypothesis has been a chal
