Cloning and Functional Analysis of Arabidopsis thaliana AtGW2, a RING-type E3 Ubiquitin Ligase Protein
OsGW2 (RING type E3 ubiquitin ligase) plays important roles in regulating rice yielding traits. According to the OsGW2 cDNA sequences, the homolog of OsGW2 was isolated from Arabidopsis thaliana by RT-PCR and designated as AtGW2. The predicted AtGW2 protein has 401 amino acids, and
has a RING-type domain. The grain size and kilo kernels weight of wild-type Arabidopsis plants were lower than those of AtGW2 RNA interference transgenic plants. These results suggested that AtGW2 negatively regulates the grain size and weight in Arabidopsis.

- Journal of plant genetic resources is devoted to reporting new and original experimental and theoretical basic research of interest to genetic resources, gene mining, brief information,and germplasm innovation. Manuscripts that are essentially reporting data, applications of data, or reviews of the literature are not suitable for publication in Journal of plant genetic resources.
Journal of plant genetic resources was founded in 2000 and is sponsored by the institute of crop sciences of chinese academy of agriculture sciences and China association of agricultural science societies. Since 2003, Journal of plant genetic resources has been indexed in China scientific journal database (CSJD), Chinese core journals (selection) database,Chinese science citation database (CSCD), and so on. - Editorial Board
