Abstract
Germin and Germin-like protein (GLP) have various proposed roles in plant developmental stages and stress- related processes. A novel GLP cDNA clone was isolated from a cDNA library of Tamarix hispida. ThGLP, coded 225aa, possesses conserved motif of plant germin and Germin-like protein. ThGLP belongs to true germin subfamily through phylogenetic analyses. Gene expression profiles in roots and leaves were evaluated using real-time quantitative RT-PCR. The results show that the gene was highly induced by drought, salt, low temperature, CdCl2 and abscisic acid treatments. Our results demonstrate that the ThGLP gene is expressed in leaves and roots, is involved in different abiotic stress responses and controlled by an ABA-dependent signaling pathway.
