    Abstract Herbaceous peony is a potential material for cut flowers, but its short vase life seriously affects the development of cut herbaceous peony flowers industry. In this study, herbaceous peony polyphenols were applied to extend the vase life of cut flowers, and the results indicated that 8% mass concentration of herbaceous peony polyphenols increased the superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT) activities; increased the soluble protein content of the cut flowers; and effectively reduced the malondialdehyde (MDA) content. Meanwhile, herbaceous peony polyphenols increased the water balance value of cut flowers. In addition, the observation of microstructures indicated that herbaceous peony polyphenols reduced the blockage mainly caused by Aspergillus spp. at the stem ends and inhibited the growth of Aspergillus spp. Additionally, aquaporin genes (AQPs), including three plasma membrane intrinsic protein genes (PlPIP1;2, PlPIP2;1, and PlPIP2;2) and one intrinsic protein gene (PlNIP), were isolated. PlPIP1;2, PlPIP2;1, and PlPIP2;2, which were induced by polyphenol treatment, had common effects on maintaining the water balance of cut flowers. Therefore, herbaceous peony polyphenols can significantly extend the vase life of cut flowers; these results provide for the application of the theoretical reference of herbaceous peony polyphenols in extending the vase life of cut flowers.

    Abstract Chlorophyll is an essential component that captures light energy to drive photosynthesis. Chlorophyll content can affect photosynthetic activity and thus yield. Therefore, mining candidate genes of chlorophyll content will help increase maize production. Here, we performed a genome-wide association study (GWAS) on chlorophyll content and its dynamic changes in 378 maize inbred lines with extensive natural variation. Our phenotypic assessment showed that chlorophyll content and its dynamic changes were natural variations with a moderate genetic level of 0.66/0.67. A total of 19 single-nucleotide polymorphisms (SNPs) were found associated with 76 candidate genes, of which one SNP, 2376873-7-G, co-localized in chlorophyll content and area under the chlorophyll content curve (AUCCC).

    Abstract As the protection of the environment gains more public attention in China, a large number of engineering slopes, which are not conducive to the growth of vegetation and are prone to natural disasters caused by constructions, are in urgent need of restoration. Herein, we explain the theoretical basis for the ecological restoration of engineering slopes and introduce the technologies commonly used in this regard, including soil improvement, bioremediation, and ecological slope protection. The benefits and evaluation of the impact of ecological restoration of engineering slopes are also detailed. Finally, we discuss the current problems in ecological restoration and put forward some future research prospects. By summarizing the existing techniques and evaluation systems for ecological restoration, this study provides a reference for its implementation and evaluation, contributing to the long-term, stable, and rapid development of ecological restoration of engineering slopes.

Zm00001d026568 and Zm00001d026569 were highly associated with SNP 2376873-7-G and encoded pentatricopeptide repeat-containing protein and chloroplastic palmitoyl-acyl carrier protein thioesterase, respectively. As expected, higher expression levels of these two genes are associated with higher chlorophyll contents. These results provide a certain experimental basis for discovering the candidate genes of chlorophyll content and finally provide new insights for cultivating high-yield and excellent maize suitable for planting environment.

    Abstract The MYB transcription factor (TF) is crucial for plant growth, development, and response to abiotic stress, but it is rarely reported in the herbaceous peony ( Paeonia lactiflora Pall.). Here, an MYB TF gene was isolated, and based on our prior mRNA data from P. lactiflora samples, it was treated with drought stress (DS). Its complete cDNA structure was 1314 bp, which encoded 291 amino acids (aa). Furthermore, using sequence alignment analysis, we demonstrated that PlMYB108 was an R2R3-MYB TF. We also revealed that PlMYB108 was primarily localized in the nucleus. Its levels rose during DS, and it was positively correlated with drought tolerance (DT) in P. lactiflora . In addition, when PlMYB108 was overexpressed in tobacco plants, the flavonoid content, antioxidant enzyme activities, and photosynthesis were markedly elevated. Hence, the transgenic plants had stronger DT with a higher leaf water content and lower H 2 O 2 accumulation compared to the wild-type (WT) plants. Based on these results, PlMYB108 is a vital gene that serves to increase flavonoid accumulation, reactive oxygen species (ROS), scavenging capacity, and photosynthesis to confer DT. The results would provide a genetic resource for molecular breeding to enhance plant DT.

    Abstract Global climate change has created a major threat to biodiversity. However, little is known about the habitat and distribution characteristics of Cinnamomum camphora (Linn.) Presl., an evergreen tree growing in tropical and subtropical Asia, as well as the factors influencing its distribution. The present study employed Maxent and a GARP to establish a potential distribution model for the target species based on 182 known occurrence sites and 17 environmental variables. The results indicate that Maxent performed better than GARP. The mean diurnal temperature range, annual precipitation, mean air temperature of driest quarter and sunshine duration in growing season were important environmental factors influencing the distribution of C. camphora and contributed 40.9%, 23.0%, 10.5%, and 7.2% to the variation in the model contribution, respectively. Based on the models, the subtropical and temperate regions of Eastern China, where the species has been recorded, had a high suitability for this species. Under each climate change scenario, the potential geographical distribution shifted farther north and toward a higher elevation. The predicted spatial and temporal distribution patterns of this species can provide guidance for the development strategies for forest management and species protection.

    Abstract With the outbreak of COVID-19, medical imaging such as computed tomography (CT) based diagnosis is proved to be an effective way to fight against the rapid spread of the virus. Therefore, it is important to study computerized models for infectious detection based on CT imaging. New deep learning-based approaches are developed for CT assisted diagnosis of COVID-19. However, most of the current studies are based on a small size dataset of COVID-19 CT images as there are less publicly available datasets for patient privacy reasons. As a result, the performance of deep learning-based detection models needs to be improved based on a small size dataset. In this paper, a stacked autoencoder detector model is proposed to greatly improve the performance of the detection models such as precision rate and recall rate. Firstly, four autoencoders are constructed as the first four layers of the whole stacked autoencoder detector model being developed to extract better features of CT images. Secondly, the four autoencoders are cascaded together and connected to the dense layer and the softmax classifier to constitute the model. Finally, a new classification loss function is constructed by superimposing reconstruction loss to enhance the detection accuracy of the model. The experiment results show that our model is performed well on a small size COVID-2019 CT image dataset. Our model achieves the average accuracy, precision, recall, and F1-score rate of 94.7%, 96.54%, 94.1%, and 94.8%, respectively. The results reflect the ability of our model in discriminating COVID-19 images which might help radiologists in the diagnosis of suspected COVID-19 patients.
