Genetic improvement of agronomic crops is necessary to cope with chilling stress. To identify the physiological factors responsible for this genotypic difference in chill-induced inhibition photosynthesis, leaf CO2 assimilation, electron flux chloroplast and antioxidant metabolism isolated chloroplasts were examined two genotypes cucumber (Cucumis sativus) plants distinct tolerance. Cucumber exposed 100 µmol m–2 s–1 at 9/7°C (day/night) 10 d then returned optimal conditions 2 d. Chilling...

The microstructure, physicochemical properties and adsorption capacities of deoiled red raspberry pomace (DRP) its total dietary fiber (DRPF) were investigated in the study, aiming to evaluate their potential use as functional food ingredients. chemical composition showed that both DRP DRPF mainly made lignin. Compared DRP, exhibited significantly decreased contents sugar, fat, crude protein, from 13.37%, 5.07% 2.58% 1.54%, 1.17% 1.37%, respectively. thermal gravity analysis revealed stable...

The NAC transcription factors (TFs) play important roles in mediating abiotic stress tolerance; however, the mechanism is still not fully known. Here, an gene (BpNAC90) from a regulatory network of Betula platyphylla (birch) that responded to drought was characterized. Overexpression and knockout BpNAC90 displayed increased reduced tolerance, respectively, relative wild-type (WT) birch. binds different DNA motifs regulate target genes conferring such as Eomes2, ABRE Tgif2. phosphorylated by...

To survive environmental challenges, plants have evolved tightly regulated response networks, including a rapid and transient general stress (GSR), followed by well-studied stress-specific responses. The mechanisms underpinning the GSR remained elusive, but functional cis-element, element (RSRE), is known to confer transcription of genes rapidly (5 min) transiently (peaking 90-120 min after stress) in vivo. investigate signal transduction events GSR, we used 4xRSRE:LUCIFERASE reporter...

The NAC (NAM, ATAF and CUC) gene family plays a crucial role in the transcriptional regulation of various biological processes has been identified characterized multiple plant species. However, genome-wide identification this not implemented Juglans mandshurica, specific functions these genes development fruits remain unknown. In study, we performed functional analysis during fruit total 114 JmNAC J. mandshurica genome. Chromosomal location revealed that were unevenly distributed 16...

Cerasus humilis is a unique dwarf shrub and fruit color an important trait in the species. In this study, we evaluated transcriptomic metabolomic profiles of plant at different developmental stages to elucidate mechanism underlying formation. metabolomics analysis, 16 anthocyanin components were identified four stages, high levels cyanidin O-syringic acid pelargonidin 3-O-beta-d-glucoside (callitephin chloride) correlated with reddening peel. A co-expression analysis revealed that ANS UFGT...

Red raspberry is a kind of fruit with high nutritional values. To evaluate the comprehensive quality 24 red varieties in Northeast China, physicochemical properties, bioactive compounds and sensory characteristics were measured, followed by principal component analysis (PCA) cluster (CA). Altogether, eight important property indexes for processing attributes selected out using PCA, including titratable acidity (TAC), sugar-acid ratio (SAR), pH, length, diameter, weight, sucrose citric acid....

Periodic drought fluctuation is a common phenomenon in Northwest China. We analyzed the response of Chinese dwarf cherry (Cerasus humilis) seedlings, shrub species with considerably strong adaptabilities, exposed to water stress (WS) by withholding for 21 d, and subsequent recovery 7 d.
