Genome-wide analysis of the laccase gene family in Arachis hypogaea and functional characterization of AhLAC63 involved in lignin biosynthesis and abiotic stress.

Plant laccases (LACs) play a vital role in lignification and participate in multiple biotic/abiotic stress responses. However, little is known about their role in lignin deposition and stress resistance in cultivated peanut (Arachis hypogaea L.).

White Light Emission in Zero-Dimensional Indium Hybrid with Hydrogen Bond.

Low-dimensional organic-inorganic metal halides (OIMHs) have been explored as single-component white light emitters for applications in solid-state lighting. Herein, we report a zero-dimensional (0D) In-based OIMH (TMPDA)[InCl(HO)] (TMPDA = -tetramethyl-1,4-phenylenediamine), which crystallizes in the noncentrosymmetric 222 space group and contains hydrogen bonds between the adjacent [InCl(HO)] octahedra in structure. It exhibits a large optical band gap (4.

Enhancing Optical Properties of Zn-Mn Solid Solution Hybrid Halides for Wide Color Gamut Backlight Displays.

Hybrid metal halides display a range of optical properties and hold promise for various applications such as solid-state lighting, anti-counterfeiting measures, backlight displays, and X-ray detection. The incorporation of zinc into (CHN)MnBr aims to enhance its structural rigidity and improve its narrow band green light emission properties. The resulting (CHN)ZnBr compound exhibits an identical crystal structure to (CHN)MnBr, indicating the potential for a solid solution of varying Zn and Mn ratios within this structural framework.

Structure and Optical Properties of Sn-Based Halide Perovskites (CHN)SnX (X = Cl, Br, I).

Low-dimensional tin-based halide perovskites are considered as eco-friendly substitutions of the iconic lead-based perovskites to host the potential as optoelectronic materials. However, a fundamental understanding of the structure-property relationship of these Sn(II)-based hybrids is still inadequate due to the limited members of this material family. To our knowledge, there is still lack of reports on a series of Sn(II)-based halide perovskites with the same organic cation but covering chloride, bromide, and iodide.

Genome-Wide Analysis of Trehalose-6-Phosphate Phosphatase Gene Family and Their Expression Profiles in Response to Abiotic Stress in Groundnut.

Trehalose-6-phosphate phosphatase (TPP) is a pivotal enzyme in trehalose biosynthesis which plays an essential role in plant development and in the abiotic stress response. However, little is currently known about in groundnut. In the present study, a total of 16 genes were identified, and can be divided into three phylogenetic subgroups.

Full-length transcriptome sequencing provides insights into alternative splicing under cold stress in peanut.

Introduction: Peanut ( L.), also called groundnut is an important oil and cash crop grown widely in the world. The annual global production of groundnuts has increased to approximately 50 million tons, which provides a rich source of vegetable oils and proteins for humans.

Genome-wide analysis of UDP-glycosyltransferase gene family and identification of a flavonoid 7-O-UGT (AhUGT75A) enhancing abiotic stress in peanut (Arachis hypogaea L.).

Background: Glycosylation, catalyzed by UDP-glycosyltransferase (UGT), was important for enhancing solubility, bioactivity, and diversity of flavonoids. Peanut (Arachis hypogaea L.) is an important oilseed and cash crop worldwide.

Metabolomics combined with transcriptomics analyses of mechanism regulating testa pigmentation in peanut.

Peanut testa (seed coat) contains large amounts of flavonoids that significantly influence seed color, taste, and nutritional qualities. There are various colors of peanut testa, however, their precise flavonoid components and regulatory mechanism of pigmentation remain unclear. In this study, a total of 133 flavonoids were identified and absolutely quantified in the seed coat of four peanut cultivars with different testa color using a widely targeted metabolomic approach.

Visualizing the Distribution of Lipids in Peanut Seeds by MALDI Mass Spectrometric Imaging.

Peanut (also called groundnut, L.) seeds are used for producing edible oils and functional foods, and offer a rich source of lipids, proteins and carbohydrates. However, the location of these metabolites has not yet been firmly established.

Fine mapping of powdery mildew and stripe rust resistance genes Pm5V/Yr5V transferred from Dasypyrum villosum into wheat without yield penalty.

The novel wheat powdery mildew and stripe rust resistance genes Pm5V/Yr5V are introgressed from Dasypyrum villosum and fine mapped to a narrowed region in 5VS, and their effects on yield-related traits were characterized. The powdery mildew and stripe rust seriously threaten wheat production worldwide. Dasypyrum villosum (2n = 2x = 14, VV), a relative of wheat, is a valuable resource of resistance genes for wheat improvement.

Characterization of an alkylresorcinol synthase that forms phenolics accumulating in the cuticular wax on various organs of rye (Secale cereale).

Alkylresorcinols are bioactive compounds produced in diverse plant species, with chemical structures combining an aliphatic hydrocarbon chain and an aromatic ring with characteristic hydroxyl substituents. Here, we aimed to isolate and characterize the enzyme that forms the alkylresorcinols accumulating in the cuticular wax on the surface of all above-ground organs of rye. Based on sequence homology with other type-III polyketide synthases, a candidate alkylresorcinol synthase was cloned.

Two oxidosqualene cyclases responsible for biosynthesis of tomato fruit cuticular triterpenoids.

The first committed step in triterpenoid biosynthesis is the cyclization of epoxysqualene into various triterpene alcohol isomers, a reaction catalyzed by oxidosqualene cyclases (OSCs). The different OSCs have characteristic product specificities, which are mainly due to differences in the numbers of high-energy intermediates the enzymes can stabilize. The goal of this investigation was to clone and characterize OSCs from tomato (Solanum lycopersicum), a species known to accumulate δ-amyrin in its fruit cuticular wax, in order to gain insights into the enzymatic formation of this particular triterpenoid.
