Abstract: A full length cDNA named PtGAPDH related to saline-alkali tolerance was cloned from Puccinellia tenuiflora by RT-PCR and RACE (rapid amplification of cDNA ends). PtGAPDH gene with 1014 bp open reading frame encoded a protein with a predicted length of 337 amino acids. Phylogenetic analysis indicates that this gene, denoted PtGAPDH, has sequence characteristics similar to other monocotyledon GAPDH genes. Northern blot shows the expression of PtGAPDH has increased with the growth of the concentration of Na2CO3 in the proper realm, otherwise, has decreased both in leaves and roots. The expression pattern of PtGAPDH gene stands for the regular effects of the saline-alkali stress on the gene expression of P. tenuiflora on the molecular standard.
