Abstract

Additional file 1: Supplementary Fig. S1. Genomic collinearity analysis of interspecies between poplar and grape, and between poplar and Arabidopsis. Gray lines represent the collinear blocks between two plants, gene pairs from different evolutionary branches are connected in different colors. Supplementary Fig. S2. Conservative RGKT motif and EAR motif of SMXL from different species. The conserved RGKT motif and EAR motif in SMXL proteins of poplar, Arabidopsis, and rice. Conserved amino acids in both motifs are marked by red boxes. Supplementary Fig. S3. Expression patterns of PtSMXLs gene in different tissues. Take roots (R), young stems (Ys), mature stems (Ms), young leaves (Yl), mature leaves (Ml), and dormant axillary buds (Bd) as samples, and the relative expression level in root was set to 1. Asterisks indicate statistically significant differences between roots and other tissues (* P ≤ 0.05, ** P ≤ 0.01).

Abstract

Chionanthus retusus is a deciduous shrub or small tree in the Oleaceae with important ornamental and economic value. In this study, fruits were collected from 22 individual C. retusus plants to study their morphological characteristics, oil content, and the contents and composition of fatty acids, phytosterols, and tocopherol. The average fruit fresh biomass, grain dry biomass, kernel dry biomass, and kernel percentage were 76.432 ± 20.75 g, 24.370 ± 6.52 g, 12.122 ± 3.21 g, and 50.16%, respectively. The average oil content of the kernels was 36.55%, ranging between 28.90% and 47.50%.The average total phytosterols content was 280.33 ± 43.96 mg/100 g. The average total tocopherols content was 578.31 ± 101.29 µg/g. In correlation analyses, the oil content was negatively correlated with the total phytosterols content (r = − 0.653, P < 0.01) and positively correlated with kernel weight (r = 0.762, P < 0.01). In principal component analyses, the first two principal components explained 77.1%,72.2%, and 91.2% of the total variance of fatty acid, phytosterol, and tocopherol composition, respectively. These results allowed us to identify germplasm resources with high oil yield, high oleic acid content, high phytosterol content, and high tocopherol content.

Abstract

In this paper, nanostructured Al2O3-40%YSZ (AZ) and nano-MoS2/Al2O3–40%YSZ (AZM) powders and coatings are prepared and studied to reveal the effect of nano-MoS2 on the friction and wear behavior of the coating. The morphology, surface roughness and hardness are observed and measured by a scanning electron microscope, a laser scanning confocal microscope and a micro-hardness tester. The ability to resist fracture of the coatings is evaluated by scratch tests. The friction and wear tests of the coatings are conducted by a ball-on-disc tribometer. The experimental results show that AZ and AZM coatings have similar morphology and roughness. But nano-MoS2 decreases the hardness and improves the ability to resist fracture of the coating. Besides, nano-MoS2 decreases the coefficients of friction of the coating when the normal loads are high. The wear rates of AZM coating decrease by 38.7%, 29.7%, 23.6% and 11% compared with those of AZ coating under normal loads of 5N, 10N, 15N and 20N. The addition of nano-MoS2 endows the coating self-lubricating function. The main wear mechanism of the coatings is micro-fracture accompanied by splat delamination and slight abrasion wear.
