Cloning and analysis of expression patterns and transcriptional regulation of RghBNG in response to plant growth regulators and abiotic stresses in Rehmannia glutinosa.

ABSTRACT: RghBNG, a gene of unknown function, was cloned from Rehmannia glutinosa by reverse transcription PCR and rapid amplification of cDNA ends. The full-length cDNA of RghBNG was 548 bp with a282-bp open reading frame. It encoded a polypeptide of 93 amino acids with a predicted molecular weight of 10.5 kDa and a theoretical isoelectric point of 9.25. Bioinformatics analysis indicated that RghBNG had no homology to any known plant genes, whereas the RghBNG polypeptide was highly similar to other plant proteins and possessed one conserved B12D protein family functional domain. Phylogenetic analysis revealed that RghBNG encoded for a dicot protein. RghBNG spatial and temporal expression patterns and responses to abiotic stresses and plant growth regulators were investigated by qRT-PCR. RghBNG tran
