Widely targeted metabolomics reveals differences in metabolites of Paeonia lactiflora cultivars.

Introduction: Paeonia lactiflora contains diverse active constituents and exhibits various pharmacological activities. However, only partial identification of biologically active substances from P. lactiflora has been achieved using low-throughput techniques.

Studying Fluorescence Sensing of Acetone and Tryptophan and Antibacterial Properties Based on Zinc-Based Triple Interpenetrating Metal-Organic Skeletons.

Two triple interpenetrating Zn(II)-based MOFs were studied in this paper. Named [Zn(1,4-bpeb)(IPA)(HO)] () and {[Zn(1,4-bpeb)(DDBA)]·2DMF} (), {1,4-bpeb = 1,4-bis [2-(4-pyridy1) ethenyl]benze, IPA = Isophthalic acid, DDBA = 3,3'-Azodibenzoic acid}, they were synthesized by the hydrothermal method and were characterized and stability tested. The results showed that had good acid-base stability and solvent stability.

Highly Water-Stable Zinc Based Metal-Organic Framework: Antibacterial, Photocatalytic Degradation and Photoelectric Responses.

A reported water-stable ([Zn(L)(bpa)(HO)]·2HO, HL = 5-(2-cyanophenoxy) isophthalic acid has been prepared via a low-cost, general and efficient hydrothermal method. It is worth noting the structural features of which exhibit the unsaturated metal site and the main non-covalent interactions including O⋯H, N⋯H and π-π stacking interactions, which lead to strong antibacterial and good tetracycline degradation ability. The average diameter of the inhibition zone against and was 12.

OsIPK2, a Rice Inositol Polyphosphate Kinase Gene, Is Involved in Phosphate Homeostasis and Root Development.

Phosphorus (P) is a growth-limiting nutrient for plants, which is taken up by root tissue from the environment as inorganic phosphate (Pi). To maintain an appropriate status of cellular Pi, plants have developed sophisticated strategies to sense the Pi level and modulate their root system architecture (RSA) under the ever-changing growth conditions. However, the molecular basis underlying the mechanism remains elusive.

Mapping Quantitative Trait Loci for High-Temperature Adult-Plant Resistance to Stripe Rust in Spring Wheat PI 197734 Using a Doubled Haploid Population and Genotyping by Multiplexed Sequencing.

Stripe rust caused by f. sp. () is a global concern for wheat production.

Inheritance of Virulence, Construction of a Linkage Map, and Mapping Dominant Virulence Genes in Puccinia striiformis f. sp. tritici Through Characterization of a Sexual Population with Genotyping-by-Sequencing.

Puccinia striiformis f. sp. tritici, the wheat stripe rust pathogen, is a dikaryotic, biotrophic, and macrocyclic fungus.

CKB1 is involved in abscisic acid and gibberellic acid signaling to regulate stress responses in Arabidopsis thaliana.

Casein kinase II (CK2), an evolutionarily well-conserved Ser/Thr kinase, plays critical roles in all higher organisms including plants. CKB1 is a regulatory subunit beta of CK2. In this study, homozygous T-DNA mutants (ckb1-1 and ckb1-2) and over-expression plants (35S:CKB1-1, 35S:CKB1-2) of Arabidopsis thaliana were studied to understand the role of CKB1 in abiotic stress and gibberellic acid (GA) signaling.

Genetic diversity revealed by morphological traits and ISSR markers in 48 Okras (Abelmoschus escullentus L.).

Okra is a widely distributed crop in the tropics, subtropics, and warmer areas of the temperate zones. Its major potential uses as a vegetable, oil and protein source, and source of paper pulp and fuel, or biomass are compatible. It is expected to have high value of exploitation and application.

Plastid casein kinase 2 knockout reduces abscisic acid (ABA) sensitivity, thermotolerance, and expression of ABA- and heat-stress-responsive nuclear genes.

Plastid casein kinase 2 (CK2) is a major Ser/Thr-specific enzyme for protein phosphorylation in the chloroplast stroma and its kinase activity is regulated by redox signals. To understand the role of CK2 phosphorylation of chloroplast proteins in abiotic stress signalling, an Arabidopsis plastid CK2 (CKA4) knockout mutant was investigated in terms of the plant response to abscisic acid (ABA) and heat stress. CKA4 expression was upregulated by ABA and heat treatment.

Regulation and function of Arabidopsis AtGALK2 gene in abscisic acid response signaling.

AtGALK2 belongs to galactokinase of GHMP family in Arabidopsis thaliana. Two homozygous T-DNA insertion mutants (Atgalk2-1 and Atgalk2-2) of the AtGALK2 gene were identified. The AtGALK2 gene was highly expressed in flowers and roots, but less in stems, leaves and petioles.

Arabidopsis F-box gene FOA1 involved in ABA signaling.

The expression of FOA1 (F-box overexpressed/oppressed ABA signaling) in different organs of Arabidopsis, and in response to ABA and NaCl, was analyzed. The expression level of FOA1 is higher in the root and is lower in the stem, and is induced rapidly by ABA and NaCl. The phenotypes of T-DNA insertion mutant foa1 and FOA1 overexpression lines FOA1ox1 and FOA1ox2 were analyzed.
