As a multifunctional material, biochar is considered potential adsorbent for removing heavy metals from wastewater. Most biochars with high adsorption capacities have been modified, but this modification uneconomical, and modifying may cause secondary pollution. Thus, it necessary to develop an efficient without modification. In study, spent P. ostreatus substrate shiitake were used as the raw materials prepare biochar. Then, physicochemical properties of their removal efficiencies Pb(II)...

In this study, could promote accumulation delay flowering cabbage. Surprisingly, we observed that BrFLS1 BrFLS3.2 were core contributors biosynthesis, BrERF2 BrERF109...

Abstract Background The vivid red, purple, and blue hues that are observed in a variety of plant fruits, flowers, leaves produced by anthocyanins, which naturally occurring pigments series biochemical processes inside the cells. purple-stalked Chinese kale, popular vegetable contains has many health benefits but needs to be investigated further identify genes involved anthocyanin biosynthesis translocation this vegetable. Results In study, purple- green-stalked kale were examined using...

Pea sprouts are considered a healthy food. Sucrose is key nutritional factor affecting taste and flavor. Meanwhile, selenium (Se) an essential micronutrient that plays multiple roles in wide variety of physiological processes improves crop quality value. Nonetheless, the effects combination sucrose Se treatment on growth, quality, sugar metabolism pea have not been explored.

Iron (Fe) plays an important role in the growth and development of plants. The effects different Fe concentrations, 1-aminocyclopropane-1-carboxylic acid (ACC), cobalt chloride (Co2+) treatments on plant growth, quality adaptive response to deficiency stress were investigated flowering Chinese cabbage. results revealed that inhibited growth. contents vitamin C, soluble protein, sugar leaves stalks significantly reduced under stress, while content cellulose nitrate was increased. clearly net...

Salvia miltiorrhiza-derived carbon dots (SmCDs), as a new type of nanomaterial, play vital roles in plant growth, antioxidation and abiotic stress alleviation. Flowering Chinese cabbage is prone to wilt yellowing after harvest. However, the SmCDs delaying senescence postharvest flowering maintain quality remain unclear. Herein, we found that had effective impacts on anti-aging, enhancing maximal fluorescence ratio, procrastinating chlorophyll degradation, sustaining reactive oxygen species...

Melatonin is known to delay postharvest nutrient loss. However, its specific roles in regulating cell wall and sugar metabolism maintain quality flowering Chinese cabbage remain unclear. In this study, was treated with melatonin (100 µmol L− 1) investigate the metabolisms. Our research found that supplementation increased levels of important nutrients like ascorbic acid, sugars, soluble protein, carotenoid, glucosinolates. It also enhanced various components (cellulose, hemicellulose,...

ABSTRACT Soil salinity severely restricts crop quality and yields. Plants have developed various strategies to alleviate stress's negative effects, including polyamine redistribution by uptake transporters (PUTs). However, the mechanisms which PUTs alter translocation processes during salt stress not been fully elucidated. Here, we show that disruption of PUT2 , is involved in shoot‐to‐root transport, results sensitivity phenotypes tomato. Moreover, yeast one‐hybrid screened for an HD‐Zip...

Abstract The red emission with suitable peak wavelength and narrow band is acutely required for high color rendering index (CRI) white LEDs without at the cost of luminous efficacy. Herein, Li 2 Ca Mg Si N 6 :Eu 2+ phosphor was prepared facile solid‐state method using 3 , 4 N, Eu O as safety raw materials under atmospheric pressure first time, which shows peaking 638 nm full width half maximum (FWHM) 62 blue light irradiation becomes desired to realize balance between efficacy CRI in LEDs....

The DnaJ proteins which function as molecular chaperone played critical roles in plant growth and development response to heat stress (HS) also called shock protein 40 based on weight. However, little was reported this gene family pepper. Recently, the release of whole pepper genome provided an opportunity for identifying putative homologous. In study, a total 76 genes (CaDnaJ01 CaDnaJ76) were identified using bioinformatics methods classified into five groups by presence complete three...

Drought stress is widespread worldwide, which severely restricts world food production. The antioxidant property of carbon dots (CDs) promising for inflammation and disease treatment.
