During the dormant period of peach trees in winter, flower buds exhibit weak cold resistance and are susceptible to freezing at low temperatures. Understanding the physiological and molecular mechanisms underlying the response of local peach buds to low-temperature adversity is crucial for ensuring normal flowering, fruiting, and yield. In this study, the experimental materials included the conventional cultivar 'Xia cui' (XC) and the cold-resistant local resources 'Ding jiaba' (DJB) peach buds.

Department of Pharmaceutical Chemistry, College of Pharmacy, King Saud University, P.O. Box 2457, Riyadh 11451, Saudi Arabia. Electronic address:

In this study, an electroluminescent (ECL) aptasensor that could efficiently and sensitively detect acetamiprid (ACE) in vegetables was constructed based on an exonuclease-assisted target cycling amplification strategy. Bimetallic RuZn-based metal-organic framework (RuZn-MOF), nucleic acid exonuclease VII (Exo VII) and tetrahedral DNA nanostructure (TDN) were used as constituent materials. First, RuZn-MOF was a substrate material with good luminescence performance and was synthesized by a hydrothermal method.

A lateral flow chromatography strip (LFS) is a chromatography-based biosensor with advantages of convenient portability, simple operation and rapid detection. In this study, a novel rapid detection technique of aptamer-based chromatography strip was developed and used for the first time for the residue detection of tetracycline antibiotics (TCs) in various milk samples. In this method, gold nanoparticles (AuNPs) modified by TCs specific aptamers were used as probes, and cationic polymers as capture molecules in a test line (T-line).

Chlorophyll (Chl) catabolism and anthocyanin synthesis play pivotal roles in determining the final skin color of fruits during maturation. However, in peach () fruit, the regulatory mechanism governing skin color, especially the Chl catabolism, remains largely elusive. In this study, we identified ten Chl catabolic genes (CCGs), with emerging as a key regulator in Chl degradation in peaches.

Time-resolved fluorescent lateral immunoassay strip (TRFLIS) is a reliable and rapid method for detecting acetamiprid. However, its sensitivity is often affected by the structural patterns and stability of the fluorescent probe. Researchers have shown significant interests in using goat anti-mouse IgG (GaMIgG) which is indirectly bound to time-resolved fluorescent microsphere (TRFM) and antibody.

In recent years, extreme weather events have become increasingly frequent, and low winter temperatures have had a significant impact on peach cultivation. The selection of cold-resistant peach varieties is an effective solution to mitigate freezing damage. To comprehensively and accurately evaluate the cold resistance of peaches and screen for high cold resistance among Gansu local resources, nine different types of peach were selected as test resources to assess physiological, biochemical, and anatomical indices.

Assessing the impact of climate change on the distribution of Osmanthus fragrans using Maxent.

Environ Sci Pollut Res Int

July 2021

Institute of Fruit and Floriculture Research, Gansu Academy of Agricultural Sciences, 730070, Lanzhou, People's Republic of China.

Models that evaluate the potential geographic distribution of species can be used with a variety of important applications in conservation biology. Osmanthus fragrans has high ornamental, culinary, and medicinal value, and is widely used in landscaping. However, its preferred habitat and the environmental factors that determine its distribution remain largely unknown; the environmental factors that shape its suitability also require analysis.

Light is indispensable for the anthocyanin accumulation of red pear (). Anthocyanin biosynthesis is catalyzed by a series of enzymes encoded by structural genes, which are regulated by a MYB-basic/helix-loop-helix-WD repeat (MYB-bHLH-WDR [MBW]) complex. The bHLH proteins of subgroup (SG) IIIf are believed to be involved in the regulation of anthocyanin accumulation.

Different densities have a great influence on the physiological process and growth of orchard plants. Exploring the molecular basis and revealing key candidate genes for different densities management of orchard has great significance for production capacity improvement. In this study, transcriptome sequencing of apple trees was carried out at three different sampling heights to determine gene expression patterns under high density(HD) and low density(LD) and the physiological indices were measured to determine the effect of density change on plants.

Light is indispensable for the accumulation of anthocyanin in the peel of red pear fruit (Pyrus pyrifolia Nakai). ELONGATED HYPOCOTYL 5 (HY5) is considered to be a critical regulator for induction of anthocyanin biosynthesis, but detailed characterization of its regulatory mechanism is needed. In this study, multiple genetic and biochemical approaches were applied to identify the roles of P.

Aiming at the seasonal drought in the dry land orchards of Longdong, Gansu Province, a sand-covering experiment was conducted with 15-year-old Nagafu No. 2 apple trees, with the soil water content, temperature, stem sap flow velocity, leaf stomatal conductance, and fruit quality measured. In the orchard covered with 5-cm-thick riversand, the increment of soil temperature in February-April was lower than 1 degrees C, while in June-July, it was 2.
