Ubiquitination is the specific modification of target proteins in cells by ubiquitin molecules, which is under the action of a series of special enzymes such as ubiquitin-activating enzymes, binding, and ligase enzymes. Ubiquitination plays an essential role in anthocyanin accumulation in plants. There are few studies on the coloring of pear peel by ubiquitin ligase E3.

Key Laboratory of Fruit Postharvest Biology of Liaoning Province, Shenyang 110866, China.

As major contributors to flavor in many fruit species, volatile esters are useful for investigating the regulation of the biosynthesis pathways of volatile aroma compounds in plants. Ethylene promotes the biosynthesis of volatile esters during fruit storage while accelerating fruit ripening; thus, the ethylene perception inhibitor 1-Methylcyclopropene (1-MCP) is employed to prolong the shelf life of fruits. However, the mechanisms by which 1-MCP regulates volatiles synthesis remain unclear.

This work aims to predict the starch, vitamin C, soluble solids, and titratable acid contents of apple fruits using hyperspectral imaging combined with machine learning approaches. First, a hyperspectral camera by rotating samples was used to obtain hyperspectral images of the apple fruit surface in the spectral range of 380~1018 nm, and its region of interest (ROI) was extracted; then, the optimal preprocessing method was preferred through experimental comparisons; on this basis, genetic algorithms (GA), successive projection algorithms (SPA), and competitive adaptive reweighting adoption algorithms (CARS) were used to extract feature variables; subsequently, multiple machine learning models (support vector regression SVR, principal component regression PCR, partial least squares regression PLSR, and multiple linear regression MLR) were used to model the inversion between hyperspectral images and internal nutrient quality physicochemical indexes of fruits, respectively. Through the comparative analysis of all the model prediction results, it was found that among them, for starch, vitamin C, soluble solids, and titratable acid content, 2 Der-CARS-MLR were the optimal prediction models with superior performance (the prediction coefficients of determination R exceeded 90% in all of them).

Changli Fruit Institute, Hebei Academy of Agriculture and Forestry Sciences, Changli, Hebei, China.

In this study, we conducted a low-temperature exothermic (LTE) investigation on 1-year-old (1a) branches of sixteen peach cultivars through a differential thermal analysis (DTA) procedure. We used a three-point approach to determine the lethal injury temperature (LT-I) of the xylem, the LTE correlation indexes, and the subordinate function value method were applied to compare cold hardiness of sixteen peach varieties. The results showed that the slope of the LT-I for the xylem of sixteen peach cultivars was different, and the LTE indexes were significantly different.

Background: In order to comprehend the regulatory mechanisms that result in the alleviation of sweet cherry pitting disorder through cold shock (0 °C ice-water mixture for 10 min), an investigation was conducted into the impacts of cold shock treatment (CST) on membrane lipid metabolism, antioxidant enzyme activity, as well as pitting of cold-stored sweet cherry fruit.

Results: CST significantly inhibited the increase in pitting incidence, pitting index, and decay incidence. The CST treatment provided greater titratable acidity, firmness as well as total content of soluble solids.

Viruses with split genomes are classified as being either segmented or multipartite based on whether their genomic segments occur within a single virion or across different virions. Despite variations in number and sequence during evolution, the genomic segments of many viruses are conserved within the untranslated regions (UTRs). In this study, we present a methodology that combines RNA sequencing with iterative BLASTn of UTRs (https://github.

Research Institute of Pomology, Chinese Academy of Agricultural Sciences, Xinghai South Street 98, Xingcheng 125100, China.

Exocarp color is a commercially essential quality for pear which can be divided into two types: green and russet. The occurrence of russet color is associated with deficiencies and defects in the cuticular and epidermal layers, which affect the structure of the cell wall and the deposition of suberin. Until now, the genetic basics triggering this trait have not been well understood, and limited genes have been identified for the trait.
