Characterization of the Stress-inducible PLATZ Gene from SoybeanDecember 16, 2015
PLATZ, or plant AT-rich sequence and zinc-binding protein, is a novel class of DNA-binding proteins whose function has not yet been identified in plants. Researchers, led by Hyun-A So and Su Jin Choi of Dong-A University in South Korea, aimed to isolate, sequence, and analyze the PLATZ gene in soybean.
The team isolated the PLATZ gene from soybean (Glycine max L.), GmPLATZ1. The gene was specifically induced by drought, high salinity, or abscisic acid (ABA) in soybean. GmPLATZ1 was also found to target the nucleus. The function of the GmPLATZ1 gene was further investigated via overexpression in transgenic Arabidopsis.
The germination in transgenic plants overexpressing GmPLATZ1 was significantly delayed in media supplemented with mannitol compared to wild-type (WT) plants. Moreover, cotyledon development in overexpressing transgenic plants was also retarded in the presence of ABA. Results suggest that GmPLATZ1 is concerned in developmental processes such as germination under osmotic stress conditions in plants.
