Physiological, ionomic, transcriptomic and metabolomic analyses reveal molecular mechanisms of root adaption to salt stress in water spinach.

Water spinach (Ipomoea aquatica Forsk.) is an important leaf vegetable affected by salt stress, however, little is known about its salt adaption mechanism. Here, we integrated physiomics, ionomics, transcriptomics, and metabolomics to analyze the root adaptation response of two water spinach varieties, BG (salt-tolerant) and MF (salt-sensitive), at 150 mM NaCl.

Mechanism of microplastics in the reduction of cadmium toxicity in tomato.

Soil pollution by microplastics (MPs) and cadmium (Cd) poses significant threats to agricultural production, yet their combined toxicity and underlying mechanisms remain poorly understood. Here, we examined the effects of three types of MPs-polyethylene (PE), polyvinyl chloride (PVC) and polypropylene (PP)-with particle sizes of 150 μm and 10 μm, in combination with Cd stress (5 mg/kg) on tomato (Solanum lycopersicum L.) growth.

Comparative analysis of the LEA gene family in seven Ipomoea species, focuses on sweet potato (Ipomoea batatas L.).

Late Embryogenesis Abundant (LEA) proteins are extensively distributed among higher plants and are crucial for regulating growth, development, and abiotic stress resistance. However, comprehensive data regarding the LEA gene family in Ipomoea species remains limited. In this study, we conducted a genome-wide comparative analysis across seven Ipomoea species, including sweet potato (I.

Genome-Wide Identification and Expression Analysis of Growth-Regulating Factor Family in Sweet Potato and Its Two Relatives.

Growth-regulating factor (GRF) is a multi-gene family that plays an important role in plant growth and development and is widely present in plants. Currently, gene members have been reported in many plants, but the gene family has not been found in sweet potato. In this study, ten genes were identified in sweet potato (), twelve and twelve were identified in its two diploid relatives () and (), which were unevenly distributed on nine different chromosomes.

Dynamically Tunable Circularly Polarized Selectivity in Plasmon-Enhanced Halide Perovskite Nanocrystal Glasses.

Ultrafast spin manipulation for optical spin-logic applications requires material systems with strong spin-selective light-matter interactions. The optical Stark effect can realize spin-selective light-matter interactions by breaking the degeneracy of spin-selective transitions with an external electric field. Halide perovskites have large exciton binding energies, which enable a room-temperature optical Stark effect.

Genome-Wide Identification and Expression Analysis of the Starch Synthase Gene Family in Sweet Potato and Two of Its Closely Related Species.

The starch synthase (SS) plays important roles in regulating plant growth and development and responding to adversity stresses. Although the family has been studied in many crops, it has not been fully identified in sweet potato and its two related species. In the present study, eight were identified from (), (), and (), respectively.

Genome-wide identification and expression analyses of CYP450 genes in sweet potato (Ipomoea batatas L.).

Background: Cytochrome P450 monooxygenases (CYP450s) play a crucial role in various biochemical reactions involved in the synthesis of antioxidants, pigments, structural polymers, and defense-related compounds in plants. As sweet potato (Ipomoea batatas L.) holds significant economic importance, a comprehensive analysis of CYP450 genes in this plant species can offer valuable insights into the evolutionary relationships and functional characteristics of these genes.

Genome-Wide Identification and Expression Analysis of Malate Dehydrogenase Gene Family in Sweet Potato and Its Two Diploid Relatives.

Preparation and Performance of a Cu@PtCu/CNF Oxygen Reduction Catalyst Membrane by Electrospinning.

A flexible carbon nanofiber film with high conductivity was prepared by electrospinning, and then Cu was uniformly deposited on the fiber film by pulse electrodeposition to prepare Cu nanocrystal/carbon nanofiber film. Cu@PtCu/carbon nanofiber (Cu@PtCu/CNF) catalytic films were synthesized by in-situ substitution reduction. The Cu@PtCu/CNF catalytic film solves the problem of uneven activity of the catalytic layer and can be directly used as the catalytic layer.

Discovery of electric devil's staircase in perovskite antiferroelectric.

The devil's staircase, describing step-like function for two competing frequencies, is well known over a wide range of dynamic systems including Huyghens' clocks, Josephson junction, and chemical reaction. In condensed matter physics, the devil's staircase has been observed in spatially modulated structures, such as magnetic ordering. It draws widespread attentions because it plays a crucial role in the fascinating phenomena including phase-locking behaviors, commensurate-incommensurate phase transition, and spin-valve effect.

Atomic reconfiguration among tri-state transition at ferroelectric/antiferroelectric phase boundaries in Pb(Zr,Ti)O.

Phase boundary provides a fertile ground for exploring emergent phenomena and understanding order parameters couplings in condensed-matter physics. In Pb(ZrTi)O, there are two types of composition-dependent phase boundary with both technological and scientific importance, i.e.

Decoding the Double/Multiple Hysteresis Loops in Antiferroelectric Materials.

Antiferroelectric materials has become one of the most promising candidates for pulsed power capacitors. The polarization versus electric-field hysteresis loop is the key electrical property for evaluating their energy-storage performance. Here, we applied in situ biasing transmission electron microscopy to decode two representative energy-storage behaviors-namely, multiple and double hysteresis loops-in (Pb,La)(Zr,Sn,Ti)O system.
