Characterization and Expression Analysis of a Retinoblastoma-Related Gene from Chinese Wild Vitis pseudoreticulata

Retinoblastoma-related (RBR) genes, a conserved gene family in higher eukaryotes, play important roles in cell differentiation, development, and mammalian cell death; however, little is known of their function in plants. In this study, a RBR gene was isolated from the Chinese wild grape, Vitis pseud...

520 |a Retinoblastoma-related (RBR) genes, a conserved gene family in higher eukaryotes, play important roles in cell differentiation, development, and mammalian cell death; however, little is known of their function in plants. In this study, a RBR gene was isolated from the Chinese wild grape, Vitis pseudoreticulata W. T. Wang clone "Baihe-35-1", and designated as VpRBR. The cDNA sequence of VpRBR was 3,030 bp and contained an open reading frame of 3,024 bp. Conceptual translation of this gene indicated a composition of 1,007 amino acids with a predicted molecular mass of 117.3 kDa. The predicted protein showed a retinoblastoma-associated protein domain A from amino acid residues 416 to 579, and domain B from residues 726 to 855. The result of expression analysis indicated that VpRBR was expressed in tissues, leaves, stem, tendrils, flower, and grape skin at different expression levels. Further quantitative reverse transcription-PCR (qRT-PCR) data indicated that VpRBR levels were higher in Erysiphe necator-treated "Baihe-35-1" and "Baihe-13-1", two resistant clones of Chinese wild V. pseudoreticulata, than in E. necator-treated "Hunan-1", a susceptible clone of V. pseudoreticulata. Furthermore, the expression of VpRBR in response to salicylic acid (SA), methyl jasmonate (MeJA), and ethylene (Eth) in grape leaves was also investigated. Taken together, these data indicate that VpRBR may contribute to some aspect of powdery mildew resistance in grape
