| Abstract: |
| A gene fragment of 3-hydroxy-3-methylglutaryl coenzyme A reductase（HMGR）was identified
from the transcriptome of Nervilia fordii（Hance）Schltr. and analyzed using bioinformatics. The results showed that
NfHMGR embodied 1 563 bases and shared high homology with other plants，which was up to 88%. NfHMGR encoded an
unstable and hydrophilic protein that contained 521 amino acids and exhibited a molecular weight of 55.34 ku. NfHMGR
protein，which was assigned to 3-hydroxy-3-methylglutaryl coenzyme A reductase superfamily，embraced 3-hydroxy-
3-methylglutaryl coenzyme A reductase Ⅰ functional domain，three transmembrane regions and none signal peptide and
transport peptide. Secondary structure prediction revealed NfHMGR was a hybrid protein. And NfHMGR gene expressed
higher in corm than in leaf. |
