A One Precursor One siRNA Model for Pol IV-Dependent siRNA Biogenesis
RNA-directed DNA methylation in Arabidopsis thaliana is driven by the plant-specific RNA Polymerase IV (Pol IV). It has been assumed that a Pol IV transcript can give rise to multiple 24-nt small interfering RNAs (siRNAs) that target DNA methylation. Here, we demonstrate that Pol IV-dependent RNAs (P4RNAs) from wild-type Arabidopsis are surprisingly short in length (30 to 40 nt) and mirror 24-n...
متن کاملPrecursor driven one pot synthesis of wurtzite and chalcopyrite CuFeS2.
A facile precursor dependent single step, one pot solution based synthesis of wurtzite and chalcopyrite polymorphs of CuFeS2 has been developed by reacting a Cu(I) thiourea complex with Fe2(SO4)3 and FeCl3 separately in ethylene glycol. The phases have been characterized by structural refinements, SEM-EDX, TEM-SAED, Raman, UV-Visible spectroscopy and TGA measurements.
