Drought stress has a significant effect on the growth, physiology and biochemistry of medicinal plants. SDIR1 (Salt- and Drought-Induced Ring Finger1), a C3H2C3-type RING-finger E3 ubiquitin ligase gene plays an important role in the stress response of various plants. However, the role of this gene
Symbiotic nitrogen fixation in legumes contributes greatly to the global nitrogen cycle on the earth. In nodules, resident rhizobia supply nitrogen nutrient fixed from atmospheric N2 to the host plant; in turn, the plant provides photosynthetic metabolites to bacteroids as a carbon source. In this
Transcription factors control many processes in plants and have high potentials to manipulate specialized metabolic pathways. Transcriptional regulation of the biosynthesis of monoterpenoid indole alkaloids (MIAs), nicotine alkaloids, and benzylisoquinoline alkaloids (BIAs) has been characterized
Isoquinoline alkaloids (IQAs), terpenoid indole alkaloid and nicotine are some of the most studied alkaloids. Recently, several groups have reported that the biosynthesis of these alkaloids is regulated by basic helix-loop-helix (bHLH) transcription factors. Whereas the biosyntheses of nicotine and
Transcription factors of the basic Helix-Loop-Helix (bHLH) family play a central role in cell proliferation, determination, and differentiation. In plants, the regulatory functions of bHLHs in phenylpropanoid biosynthesis have been well established with regard to other interacting-proteins; i.e.,
Plant alkaloids, one of the largest groups of natural products, provide many pharmacologically active compounds. Several genes in the biosynthetic pathways for scopolamine, nicotine, and berberine have been cloned, making the metabolic engineering of these alkaloids possible. Expression of two
