Overexpression of Potato Gene in Tobacco Enhances the Transgenic Plant Tolerance to Drought Stress.

PYR/PYL/RCAR proteins are abscisic acid (ABA) receptors that play a crucial role in plant responses to abiotic stresses. However, there have been no research reports on potato PYL so far. In this study, a potato gene named was identified based on transcriptome data under drought stress.

Genome-Wide Identification of R2R3-MYB Family Genes and Their Response to Stress in .

Background: genes comprise one of the largest and most important gene families in plants, and are involved in the regulation of plant growth and development as well as responses to abiotic stresses. However, the functions of genes in remains largely unknown.

Methods: Here, a comprehensive genome-wide analysis of genes was performed, in which phylogenic relationships, gene structures, motif composition, chromosomal locations, collinearity analysis, and -acting elements were investigated.

ICP-MS based metallomics and GC-MS based metabolomics reveals the physiological and metabolic responses of plants exposed to FeO nanoparticles.

It is found that the growth of was dependent on FeO, while the bioavailability of plants to ordinary FeO was low on the earth. In order to improve the growth, quality and yield of , we used FeO NPs (100 or 200 mg/L) that was easily absorbed by plants as nano-fertilizer to hydroponically treat seedlings of for 3 weeks. FeO NPs induced not only earlier flowering and increased sugar content and photosynthesis, but also stressed to plants, increased MDA content and related antioxidant enzymes activities.

Genome-wide identification of R2R3-MYB family genes and gene response to stress in ginger.

Ginger (Zingiber officinale Roscoe) is an important plant used worldwide for medicine and food. The R2R3-MYB transcription factor (TF) family has essential roles in plant growth, development, and stresses resistance, and the number of genes in the family varies greatly among different types of plants. However, genome-wide discovery of ZoMYBs and gene responses to stresses have not been reported in ginger.

Comparative Proteome and Phosphoproteome Analyses Reveal Different Molecular Mechanism Between Stone Planting Under the Forest and Greenhouse Planting of .

The highly esteemed Chinese herb, , whose major metabolites are polysaccharides and alkaloids, is on the verge of extinction. The stone planting under the forest (SPUF) and greenhouse planting (GP) of are two different cultivation methods of pharmaceutical Dendrobium with significantly differences in morphology, metabolites content and composition, and medication efficacy. Here, we conducted proteomics and phosphoproteomics analyses to reveal differences in molecular mechanisms between SPUF and GP.

Molecular Cloning and Functional Characterization of a β-Glucosidase Gene to Produce Platycodin D in .

Platycodin D (PD) is a deglycosylated triterpene saponin with much higher pharmacological activity than glycosylated platycoside E (PE). Extensive studies showed that the transformation of platycoside E to platycodin D can be achieved using β-glucosidase extracted from several bacteria. However, whether similar enzymes in could convert platycoside E to platycodin D, as well as the molecular mechanism underlying the deglycosylation process of platycodon E, remain unclear.

A candidate gene identified in converting platycoside E to platycodin D from Platycodon grandiflorus by transcriptome and main metabolites analysis.

Platycodin D and platycoside E are two triterpenoid saponins in Platycodon grandiflorus, differing only by two glycosyl groups structurally. Studies have shown β-Glucosidase from bacteria can convert platycoside E to platycodin D, indicating the potential existence of similar enzymes in P. grandiflorus.
