Resveratrol enhances the tolerance of to potassium deficiency stress.

Potassium (K) deficiency in plants can lead to metabolic disorders and growth retardation. Currently, nearly 50% of the arable land in China is experiencing a K resource deficit, significantly hindering the development of the apple industry. Resveratrol (Res), a phytoalexin, has been extensively reported to enhance plant resistance against various abiotic stresses.

Research on Fire-Detection Algorithm for Airplane Cargo Compartment Based on Typical Characteristic Parameters.

To clarify the reasons for inaccurate fire detection in aircraft cargo holds, this article depicts research from the perspective of a single type of sensor detection. In terms of fire smoke, we select dual-wavelength photoelectric smoke sensors for fire-data collection and a genetic algorithm to optimize the classification and detection of random forest fires. From the perspective of fire CO concentration, we use PSO-LSTM to train a CO concentration compensation model to reduce sensor measurement errors.

Convenient intelligent diagnosis for rotating machinery: An improved deep forest method based on feature reconstruction.

Due to the advantages of feature autoextraction and deep architecture, deep learning-based intelligent fault diagnosis has attracted increasing attention. However, a variety of complex hyper-parameter settings greatly limit its practical applications. Moreover, it is more critical and difficult to diagnose multiple mixed faults of rotating machinery under small training samples.

Apomictic plants exhibit abnormal pollen development.

Apomixis is the asexual reproduction through seeds that leads to the production of genetically uniform progeny. It has become an important tool in plant breeding because it facilitates the retention of genotypes with desirable traits and allows seeds to be obtained directly from mother plants. Apomixis is rare in most economically important crops, but it occurs in some species.

A loop-mediated isothermal amplification-enabled analytical assay for the detection of SARS-CoV-2: A review.

The number of words: 4645, the number of figures: 4, the number of tables: 1The outbreak of COVID-19 in December 2019 caused a global pandemic of acute respiratory disease, and with the increasing virulence of mutant strains and the number of confirmed cases, this has resulted in a tremendous threat to global public health. Therefore, an accurate diagnosis of COVID-19 is urgently needed for rapid control of SARS-CoV-2 transmission. As a new molecular biology technology, loop-mediated isothermal amplification (LAMP) has the advantages of convenient operation, speed, low cost and high sensitivity and specificity.

Screening of lactic acid bacteria strains with urate-lowering effect from fermented dairy products.

Hyperuricemia is a well-known cause of gout and also a risk factor for various comorbidities. Current agents like xanthine oxidase inhibitors prevent hyperuricemia, but usually induce severe side effects. Alternative strategies, such as novel dietary supplementations, are necessary for the management of hyperuricemia.

B-box containing protein 1 from (MdBBX1) is involved in the abiotic stress response.

However, the molecular functions underlying the activity of plant BBXs in response to abiotic stress remain largely unclear. In this investigation, we found that a BBX from () was involved in the response to various abiotic stresses.

Whole genome re-sequencing and transcriptome reveal an alteration in hormone signal transduction in a more-branching mutant of apple.

Branch number is an important trait in grafted apple breeding and cultivation. To provide new information on molecular mechanisms of apple branching, whole reduced-representation genomes and transcriptome of a wild-type (WT) apple (Malus spectabilis) and its more-branching (MB) mutant at the branching stage were examined in this study. Comparison of WT and MB genomes against the Malus domestica reference genome identified 14,908,939 single nucleotide polymorphisms (SNPs) and 173,315 insertions and deletions (InDels) in WT and 1,483,221 SNPs and 1,725,977 InDels in MB.

Identification and functional characterization of a new flavonoid synthase gene MdFLS1 from apple.

The flavonoid synthase gene MdFLS1 from apple, which possibly plays an important role in anthocyanin synthesis, accumulates in the purple-red branches of Malus 'Pink spire'. Flavonoid metabolism serves an important function in plant growth and development. In this study, we selected 20 varieties of apple lines, 10 green and ten red branches, from the plant nursery of Qingdao Agriculture Academy.

Role of Cytokinin, Strigolactone, and Auxin Export on Outgrowth of Axillary Buds in Apple.

Shoot branching is regulated by phytohormones, including cytokinin (CK), strigolactone (SL), and auxin in axillary buds. The correlative importance of these phytohormones in the outgrowth of apple axillary buds remains unclear. In this study, the outgrowth dynamics of axillary buds of a more-branching mutant (MB) and its wild-type (WT) of were assessed using exogenous chemical treatments, transcriptome analysis, paraffin section, and reverse transcription-quantitative PCR analysis (RT-qPCR).

Genomewide analysis of homeobox gene family in apple ( Borkh.) and their response to abiotic stress.

Homeobox proteins (HOXs) comprise a large family in eukaryotes and share a highly conserved DNA-binding motif, the homeodomain (HD). HOXs play an important role in the regulation of plant growth, development and stress response. However, systematic analysis and expression profiling of these genes have not been reported in .

Complete Genome Sequence of Lactobacillus reuteri WHH1689, Isolated from Traditional Chinese Highland Barley Wine.

Potential probiotic characterization of Lactobacillus reuteri from traditional Chinese highland barley wine and application for room-temperature-storage drinkable yogurt.

The aim of this study was to select probiotic strains that could be used in drinkable yogurt to yield viable cells following storage at room temperature (RT). The uniquely high altitude conditions in Tibet and the alcoholic environment of certain products, such as the highland barley wine homemade in Tibet, may induce unusual characteristics of microbial strains. A total of 27 lactic acid bacteria were isolated from homemade highland barley wines.
