We profiled and quantified primary and secondary metabolites in the leaves and roots of xBrassicoraphanus (Baemuchae), Brassica campestris ssp. pekinensis (Chinese cabbage), and Raphanus sativus (radish). We obtained 72 metabolites from leaves and 68 metabolites from both leaves and roots of xBrassicoraphanus, Chinese cabbage, and radish. The metabolic profiles in this study revealed intermediate-level production of most metabolites from different parts of Baemuchae compared with that from different parts of Chinese cabbage and radishes. This was supported by the results of principal component analyses for the detected metabolites, which indicated that the Baemuchae group was located between the Chinese cabbage and radish groups. In particular, several amino acids (phenylalanine, tryptophan, and methionine) played the main role in phenylpropanoid and glucosinolate biosynthesis and were positively correlated with phenolic compounds, indolic glucosinolates, and aliphatic glucosinolates, respectively, in different parts. Furthermore, analysis of different species revealed the presence of 10 different glucosinolates, 10 phenolics, and 7 carotenoids, and their levels varied in the roots and leaves of the studied species. Among the leaves of the three species, Chinese cabbage had the highest total glucosinolate level, which was 3.14 times higher than the lowest level observed in radish. Baemuchae had the highest total phenolic compound level, which was 2.87 times higher than the lowest level found in Chinese cabbage, and radish had the highest carotenoid level, which was 12.41 times higher than the lowest one observed in Chinese cabbage. In the roots of Baemuchae, Chinese cabbage, and radish, glucosinolate levels did not vary significantly. Chinese cabbage contained the highest total phenolic compound level, which was 2.38 times higher than the lowest level found in radish, and the highest total carotenoid level, which was 2.49 times higher than the lowest level observed in Baemuchae. This metabolomic study provided chemical composition information that can be applied to future breeding strategies and comprehensively described the relationship among metabolites detected in the three plant species.

“…pekinensis ), which originated in China, is one of the largest and most productive vegetable crops grown in China. It is highly consumed in Asian countries and is one of the most important vegetable crops in the world [ 34 , 35 , 36 ]. In Chinese cabbage, heterosis is evident and employed as an effective way and important means to improve yield, disease resistance, stress resistance and quality.…”

In Chinese cabbage breeding, hybrids have made a terrific contribution due to heterosis, the superior performance of offspring compared to their inbred parents. Since the development of new, top-performing hybrids requires a large scale of human and material resources, the prediction of hybrid performance is of utmost interest to plant breeders. In our research, leaf transcriptome data from eight parents were used to investigate if they might be employed as markers to predict hybrid performance and heterosis. In Chinese cabbage, heterosis of plant growth weight (PGW) and heterosis of head weight (HW) were more obvious than other traits. The number of differential expression genes (DEGs) between parents was related to the PGW, length of the biggest outer leaf (LOL), leaf head height (LHH), leaf head width (LHW), HW, leaf number of head (LNH) and plant height (PH) of hybrids, and up-regulated DEGs number was also associated with these traits. Euclidean and binary distances of parental gene expression levels were significantly correlated with the PGW, LOL, LHH, LHW, HW and PH of hybrids. Additionally, there was a significant correlation between the parental expression levels of multiple genes involved in the ribosomal metabolic pathway and hybrid observations and heterosis in PGW, with the BrRPL23A gene showing the highest correlation with the MPH of PGW(r = 0.75). Therefore, leaf transcriptome data can preliminarily predict the hybrid performance and select parents in Chinese cabbage.

Light is one of the five indispensable factors for plant growth. Green houses and plant factories have advantages of growing vegetables off-season and high production. However, artificial lighting occupies most of the running cost during the operation of plant factories, and intelligent and programmable light-emitting diodes (LEDs) have been considered to be used as growing lamps to save energy. Taking both the photosynthetic and the visual performances into consideration, luminescent spectrum of LEDs based on quantum dot (QD) materials is designed and optimized according to the photosynthetic action spectrum (PAS) of plants. In our calculation, the three-band QD-based LEDs (QLEDs) show a highest photosynthetic action factor (PAF) of 8.088 and a highest induced photosynthetic index (IPI) of 4.012. The four-band QLEDs show a highest PAF of 7.689 and a highest IPI of 3.818. CdZnS/ZnS and CdZnS/ZnSe QDs are also synthesized for fabricating three-and four-band QLEDs. Investigations of the photosynthetic and the vison performances on these devices are consistent with those theoretical simulation results. Both the simulation and the experimental results show that either the three-or the four-band QLEDs has better photosynthetic parameters than those of the conventional light sources. The fabricated four-band QLED under different applied current exhibits a highest PAF of 2.6942 and a highest IPI of 1.3621. For the vison performances, the four-band device demonstrate a highest CRI of 93 and a highest CCT of 2053 K. Despite the visual performances of the four-band QLEDs show improvement than those of the three-band ones, they still need to be improved to offer better visual experience for human eyes. With further investigation on the synthesis of emission tunable QD materials and the optimization of the spectrum, highly efficient QLEDs with both good photosynthetic and visual performances are expected to be applied in the field of growing lamps.
