abstract
The glycine-(r) under bar ich (p) under bar rotein AtGRP2 is one of the four members of the cold-shock domain (CSD) protein family in Arabidopsis. It is characterized by the presence of a nucleic acid-binding CSD domain, two glycine-rich domains and two CCHC zinc-fingers present in nucleic acid-binding proteins. In an attempt to further understand the role of CSD/GRP proteins in plants, we have proceeded to the functional characterization of the AtGRP2 gene. Here, we demonstrate that AtGRP2 is a nucleo-cytoplasmic protein involved in Arabidopsis development with a possible function in cold-response. Expression analysis revealed that the AtGRP2 gene is active in meristematic tissues, being modulated during flower development. Down-regulation of AtGRP2 gene, using gene-silencing techniques resulted in early flowering, altered stamen number and affected seed development. A possible role of AtGRP2 as an RNA chaperone is discussed.
