Abstract

Calcium is a ubiquitous and essential secondary messenger in eukaryotic signal transduction pathways. Calcium binding protein, as a component of pathways, plays various roles in response to biotic and abiotic stresses, as well as in developmental processes in plants. In this study, a calcium binding protein gene, designated as TaCab1 (Triticum aestivum calcium binding EF-hand protein 1), was isolated and characterized from wheat leaves (cv. Suwon 11) infected by Puccinia striiformis f. sp. tritici by in silico cloning and reverse transcription PCR (RT-PCR). TaCab1 did not have an intron and was predicted to encode a 216 amino acid protein which possesses an N-terminal region with a signal peptide, a transmembrane domain, an EF-hand motif and a caleosin domain. The results of transient assays with constructs of TaCab1 with green fluorescent protein (GFP) gene indicated that TaCab1 encodes a transmembrane protein. Quantitative real-time PCR (qRT-PCR) analyses revealed that TaCab1 was highly expressed in leaves than roots and stems. Although up-regulated expression profiles of TaCab1 were quite similar in both incompatible and compatible interactions, its transcript accumulation in the compatible interaction was much higher than in the incompatible interaction. The transcription of TaCab1 was also up-regulated at different degrees after treated by phytohormones [abscisic acid, benzyl adenine, ethylene, methyl jasmonate and salicylic acid (SA)] and stress stimuli [wounding, low temperature, polyethylene glycol and high salinity]. These results suggest that TaCab1 is involved in the plant-pathogen recognition, symptom development, and the basal tolerance to biotic and abiotic stresses through the SA signaling pathway.
