China is the origin and evolutionary centre of Oriental pears. Pyrus betuleafolia a wild species native to distributed in northern region, it widely used as rootstock. Here, we report de novo assembly genome P. betuleafolia-Shanxi Duli using an integrated strategy that combines PacBio sequencing, BioNano mapping chromosome conformation capture (Hi-C) sequencing. The size was 532.7 Mb, with contig N50 1.57 Mb. A total 59 552 protein-coding genes 247.4 Mb repetitive sequences were annotated...
Germplasm resources are an important basis for genetic breeding and analysis of complex traits, research on diversity is conducive to the exploration creation new types germplasm. In this study, distribution frequency, coefficient variation, Shannon–Wiener index, variance cluster analyses were used analyze trait differences 39 fruit phenotypic traits from 570 pear accessions, which included 456 accessions 11 species 114 interspecific hybrid cultivars that had been stored in National...
Abstract Background 'Kuerlexiangli’ ( Pyrus sinkiangensis Yu), a native pear of Xinjiang, China, is an important agricultural fruit and primary export to the international market. However, with persistent calyxes affect shape quality. Although several studies have looked into physiological aspects calyx abscission process, underlying molecular mechanisms remain unknown. In order better understand basis process abscission, materials at three critical stages regulation, 6000 × Flusilazole plus...
Porcine deltacoronavirus (PDCoV) is a recently discovered RNA virus that belongs to the family Coronaviridae and genus Deltacoronavirus. This causes enteric disease in piglets characterized by enteritis diarrhoea. In our present investigation, 189 diarrhoeic samples were collected between July 2016 May 2017 from Tibetan pigs inhabiting three different provinces surrounding Qinghai–Tibet Plateau of China. We then applied molecular-based method reverse transcription polymerase chain reactions...
Located in the southwestern region of China, Yunnan–Kweichow Plateau, is closely related to origins Pyrus L. Despite this important status, there has been relatively little population genetics research focused on wild species area. To address gap knowledge, present study was conducted investigating distributions Plateau region. These analyses entailed collection 80 accessions, whole-genome resequencing, and detection variants including SNPs, InDels, SVs, CNVs. Genetic structure revealed...
Flesh texture is an important quality trait and related to people’s preference for fruit, especially crisp pears. Puncture tests were carried out on 156 pear fruit germplasm samples analyze the diversity level of traits, clarify correlation between sensory description evaluation instrumental explore effects ripening, size, shelf life change in flesh texture. The results showed that puncture parameters significantly different cultivars, work associated with limit compression force had highest...
Abstract Background Pyrus ussuriensis Maxim. are rich in nutrients, with a pleasant aroma and postharvest softening properties. Postharvest influences shelf life of fruit quality. Melatonin is natural safe preservative, which can effectively maintain quality after harvesting, delay fruit. The aim study was to elucidate mechanism pear during storage effect melatonin. Results Ethylene production rate, respiration weight loss fruit, soluble solid content, titratable acidity were assessed,...
Introduction Biochar-based fertilizers (BF) have emerged as a promising strategy to improve soil physicochemical and biological properties, thereby enhancing tea yield quality. Methods A field experiment was conducted using two types of BF- ordinary BF (BF1, containing 15% biochar) optimized (BF2, 30% biochar)- applied for either 1 or 2 years. The effects on the nutrients, plant growth, quality, metabolomics profiles were assessed. Results showed that application significantly increased pH...
Aroma is an important sensory factor in evaluating the quality of pear fruits. This study used headspace solid-phase microextraction (HS-SPME) combined with gas chromatography–mass spectrometry (GC-MS) to analyze volatile organic compounds (VOCs) three crispy pears and five soft during shelf life, changes soluble solids content (SSC) were analyzed. The results showed that SSC such as Nanguoli, Jingbaili Louis was always higher than throughout life. A total 160 VOCs detected eight varieties....
Saline soil is a serious problem worldwide, and it necessary to improve the salt tolerance of plants so as avoid progressive deterioration saline soil. Here we report that over-expression AtNHX1 improves in transgenic tall fescue. The gene driven with CaMV35S promoter was constructed into plant expression vector pGreen0229, introduced embryonic calli hypocotyls fescue (Festuca arundinacea ) by particle bombardment. Regenerated plantlets were obtained screening herbicide (PPT, 2 mg/L),...
Pears are popular among consumers for their juicy and delicious taste. In this study, the sugar organic acid compositions of pear fruits with different texture types during development were determined by ultra-performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS), fruit traits a analyzer. The results showed that dominant in soft crispy was fructose. main difference between pears second-highest component; glucose content higher crispy-flesh while sucrose soft-flesh fruits....
There are strong economic drivers for understanding the process of fruit post-harvest softening. In this study, liquid chromatography with electrospray ionization tandem mass spectrometry was used to analyze metabolite changes in 'Zaoshu Shanli' after different storage periods; wild accession Pyrus ussuriensis presents good quality and relatively low flesh firmness storage. The lipid metabolites were significantly higher at 18 days compared those 0 storage, glycerophospholipid metabolism...
SummaryOne-hundred and six accessions of Pyrus, including 87 local Chinese P. pyrifolia, were identified genetically using nine microsatellite (simple sequence repeat) loci developed from apple pear. A total 147 putative alleles obtained. Among the 106 accessions, 100 could be differentiated successfully, except for three pairs synonymous or mutants. For number per locus ranged ten to 21, with an average 15.3. The observed heterozygosity polymorphic information content 0.60 0.75,...
Pyrus xerophila has strong resistance to drought, cold, salt, and rust. It is one of the main rootstock types pear in Northwest China, with high production value. However, its habitat seriously damaged. The prediction geographical distribution P. under different climate scenarios will provide important scientific basis for rational development utilization resources protection diversity. Based on MaxEnt model ArcGIS spatial analysis, potential pattern current future (2050, 2070) was...
