Further, to understand the mechanism underlying ovarian AA accumulation, the expression levels of SMP30/GNL and GULO genes were measured. Expression of both the genes was significantly suppressed, which suggested a lowered AA synthesis in the PMSG treated rat ovary. For further understanding, mRNA expression of AA transporters SVCT1 and SVCT2 encoded by SLC23A1 and SLC23A2 genes respectively were measured, which showed increased level of SVCT1 expression. https://www.selleckchem.com/products/zasocitinib.html These observations suggested that the increased AA content might not be due to increased synthesis of AA within the ovary but possibly due to increased uptake from blood during the stimulation of follicular growth. Cymbidium faberi Rolfe (Orchidaceae) is an herbaceous plant native to China, where it has a long history of cultivation owing to its beautiful flower pattern and floral fragrance. Previously, we conducted a transcriptome analysis of the flower and vegetative buds to elucidate the mechanisms of flower development in C. faberi. In the present study, we found nine secondary metabolic pathways through the KEGG pathway database that were related to the biosynthesis of methyl jasmonate (MeJA) and other volatile organic compounds. qRT-PCR was performed to analyze the expression levels of four key genes in the MeJA pathway. Among these, CfJMT (jasmonic acid carboxyl methyltransferase) had higher transcript levels in sepals, petals and labella than in other tissues. CfJMT was cloned from the petals of full-bloom flowers of C. faberi. The predicted CfJMT protein sequence contains conserved jasmonic acid methyl transferase-7 domains, indicating that it belongs to the SABATH protein family. The CfJMT coding sequence driven by the CaMV35S promoter was successfully transformed into Petunia hybrida through an Agrobacterium-mediated method. Although MeJA could not be detected in either wild-type or transgenic petunia plants, the leaves of the transgenic plants were smaller than those of wild-type plants and pollen development was abnormal. These results indicate that heterologous expression of CfJMT may change the levels of endogenous jasmonic acid and other hormones, but that the content of MeJA is not increased significantly by transformation with CfJMT alone. Thus, other related genes and regulation factors may play important roles in this process. Norharmane is an indole alkaloid that can be found in several terrestrial plants, as well as in some dinoflagellates and cyanobacteria. The aim of this study was to focus on the way this metabolite impacts the plant metabolism of the model species Arabidopsis thaliana. This metabolite caused increase of secondary and adventitious roots, as well as torsion, toxic effects, and a decrease in root length. Moreover, norharmane altered the cellular arrangement, resulting in unfinished cell walls, decreased auxin content and inhibited PIN proteins activity. All the alterations suggest that norharmane alters polar auxin transport by inhibiting PIN2, PIN3 and PIN7 transport proteins, thus causing a significant inhibitory effect on the growth of A. thaliana seedlings. HYPOTHESIS The CO2-sensitive dispersion/precipitation transition of polymer latexes fabricated based on a responsive emulsifier is a promising way to conveniently acquire bulk polymer materials. Nevertheless, the tedious synthesis procedures for switchable surfactants and the harsh operating requirements for the sensitive latexes constrain the applicability of the approach for latex preparation. Therefore, a new strategy for generating latexes with tunable CO2 responsiveness in a maneuverable way is urgently needed. EXPERIMENTS In this work, a CO2-switchable electrostatic interaction is introduced to construct responsive latexes. A series of lightly crosslinked poly(diethylaminoethyl methacrylate-styrene) [P(DEA-St)] latexes with different PDEA contents were fabricated via one-pot emulsion copolymerization, with divinylbenzene and sodium dodecylsulfate (SDS) used as the crosslinker and anionic emulsifier, respectively. The influence of the DEA feeding ratio on the resulting P(DEA-St) colloids was characterized by Fourier transform infrared spectroscopy and scanning electron microscopy. Then, a cyclic CO2/N2 input was introduced to verify the response transitions of polymer latexes. FINDINGS Accompanied by the stepwise decrease of DEA feeding ratio, the morphology of the resulting copolymerized nanoparticles changed from an ambiguous bulge to the typical spherical pattern. In addition, the P(DEA-St) latexes treated by cyclic CO2/N2 exhibit four different types of response modes, namely (i) CO2-switchable swelling/deswelling transition, (ii) CO2-reversible dispersion/coagulation transition, (iii) CO2-induced irreversible destabilisation and (iv) CO2-insensitive latexes. The CO2-responsive destabilisation is highly applicable in the separation and transportation fields of commercial latex products, such as poly(methyl methacrylate), poly(n-butyl acrylate) and poly(butyl methacrylate) colloids. Carbon dots (CDs) with concentration-modulated luminescence were obtained by pyrolysis of citric acid (CA) and thiourea (TU). CDs exhibit multi-colored emission by varying their concentrations. As a contrast, Zr-doped CDs (ZrCDs) were prepared from CA, TU and ZrCl4 in a similar way. To our surprise, no concentration-dependent emission were observed in ZrCDs. Structural and optical characterizations prove that the concentration-tunable fluorescence is attributed to the aggregation between CDs. As the concentration increases, the aggregation of CDs results in a gradual decrease in the band gaps (from 2.18 eV to 1.56 eV), which ultimately causes the fluorescence to redshift continuously. However, ZrCDs are always in a highly dispersed state no matter how the concentration goes up, the zirconium complexes on the surface of ZrCDs prevents them from aggregation and maintains the band gap of ZrCDs at about 2.21 eV. Therefore, we proposed an aggregation-induced multicolor emission mechanism for CDs, which has a certain reference significance for exploiting the potential applications of CDs. In this paper, double-layered mesopore-rich hollow carbon microspheres (DHCM) were prepared by a Stöber method using tetraethyl orthosilicate, resorcinol and formaldehyde as precursor materials, and further utilized as carbon sources to prepare the boron and nitrogen co-doped double-layered mesopore-rich hollow carbon microspheres (B, N-DHCM) by hydrothermal approach utilizing ammonium tetraborate tetrahydrate (NH4B5O8·4H2O) as boron and nitrogen sources. Compared with the undoped DHCM, the as-obtained B, N-DHCM displays improved capacitive properties with a high specific capacitance (221.5 F g-1 at 1 A g-1), good rate performance (104.1 F g-1 at 20 A g-1) and superior cycle life (91% of capacitance retention at 3 A g-1 after 10,000 cycles). The outstanding capacitive performances result from the synergistic effect of the unique double-layered mesopore-rich hollow structure contributing to the rate property and cycle stability and the modification of B and N co-doping providing pseudocapacitance for the enhancement of specific capacitance.
