Effect of Irradiation Insecticidal Technology on Micro-ecology, Physical and Chemical Properties of Strong-flavor Baijiu Daqu

Research Square (Research Square) (2023)

Yu Wang Jiahao Xue Yue Qiu Xiao‐Peng Zhang Dan Wang

Abstract In this paper, the influence of high-energy electron beam irradiation technology on the microecology of strong-flavor Baijiu Daqu (SBD) was studied. The effects of different irradiation doses (0-3.55 kGy) on the microecology and physicochemical properties of SBD were determined. The interaction between bacteria, fungi, and physicochemical factors in SBD was examined. The potential of 0-1.40 kGy irradiation for pests eradication was analyzed. Under the irradiation dose range of 0.27–1.40 kGy, the micro-ecology of SBD could almost return to the level observed in non-irradiated samples within 3 months, ensuring a storage period of up to 120 d without infestation. Liquefying Power, Saccharifying Power, Acidity and Moisture all meet the industry standards of SBD and can be used for liquor making. The total bacterial count in SBD was approximately 1.4 x 10 4 CFU/g, while the count of fungi and yeast was about 4.4 x 10 4 CFU/g. This study provides an experimental reference for the application of electron beam irradiation technology in the insecticidal treatment of SBD.

Evaluation of the Toxicity and Sublethal Effects of Acetamiprid and Dinotefuran on the Predator Chrysopa pallens (Rambur) (Neuroptera: Chrysopidae)

Toxics (2022)

Yue Su Xiangliang Ren Xiaoyan Ma Dan Wang Hongyan Hu

Neonicotinoid insecticides affect the physiology or behavior of insects, posing risks to non-target organisms. In this study, the effects of sublethal doses of two neonicotinoid insecticides, acetamiprid and dinotefuran, against Chrysopa pallens (Rambur) (Neuroptera: Chrysopidae) were determined and compared. The results showed that acetamiprid and dinotefuran at LD10 (8.18 ng a.i. per insect and 9.36 ng a.i. per insect, respectively) and LD30 (16.84 ng a.i. per insect and 15.01 ng a.i. per insect, respectively) significantly prolonged the larval stages and pupal stages (except acetamiprid LD10), compared to control. In addition, acetamiprid and dinotefuran at LD30 significantly prolonged the adult preoviposition period (APOP) and total preoviposition period (TPOP). In contrast, the two insecticides at LD10 and LD30 had no significant effect on the longevity, fecundity, reproductive days, preadult survival rate (%), intrinsic rate of increase (r), net reproductive rate (R0), and finite rate of increase (λ). These results provide a theoretical basis for the rational use of these two insecticides and the utilization and protection of C. pallens.

The disease quantification analysis of cotton Verticillium wilt using the two methods of disease index and fungal biomass present high consistency

Plant Protection Science (2024)

He Zhu Yue Li X. B. Ji Dandan Zhang Jieyin Chen

Verticillium dahliae is a broad host-range pathogen that causes vascular wilt in plants. The Verticillium wilt disease severity assay on plants caused by V. dahliae mainly includes two methods, one is a plant disease grade classification based on disease severity statistics [namely the disease index (DI)], and the other is the V. dahliae biomass quantification in plants (namely the fungal biomass). In this study, the relationships of pathogenicity with the DI, pathogenicity with the biomass, and the correlation analysis of the DI and relative fungal biomass were analysed. The results showed that the pathogenicity assessment of V. dahliae strains using the DI method was able to give an intuitive reflection of the pathogenic ability for defoliating and non-defoliating strains; moreover, the method of quantitative PCR for fungal biomass also had high repeatability and stability. As a whole, the correlation coefficient between the DI and fungal biomass values of 28 strains was 0.728, indicating that the two data sets were highly correlated; however, the correlation coefficients of the defoliating strains and non-defoliating strains were only 0.5384 and 0.4547, respectively. In conclusion, the correlation coefficient between the DI and the fungal biomass presented high consistency, which could provide some meaningful exploration for the more accurate pathogenicity identification of V. dahliae.

Impact of nitrogen allocation on growth and photosynthesis of Miscanthus (Miscanthus × giganteus)

GCB Bioenergy (2012)

Dan Wang Mathew W. Maughan Jindong Sun Xiaohui Feng Fernando E. Miguez

Abstract Nitrogen (N) addition typically increases overall plant growth, but the nature of this response depends upon patterns of plant nitrogen allocation that vary throughout the growing season and depend upon canopy position. In this study seasonal variations in leaf traits were investigated across a canopy profile in Miscanthus ( Miscanthus × giganteus ) under two N treatments (0 and 224 kg ha −1 ) to determine whether the growth response of Miscanthus to N fertilization was related to the response of photosynthetic capacity and nitrogen allocation. Miscanthus yielded 24.1 Mg ha −1 in fertilized plots, a 40% increase compared to control plots. Photosynthetic properties, such as net photosynthesis (A), maximum rate of rubisco carboxylation (V cmax ), stomatal conductance (g s ) and PSII efficiency (F v '/F m '), all decreased significantly from the top of the canopy to the bottom, but were not affected by N fertilization. N fertilization increased specific leaf area ( SLA ) and leaf area index ( LAI ). Leaf N concentration in different canopy layers was increased by N fertilization and the distribution of N concentration within canopy followed irradiance gradients. These results show that the positive effect of N fertilization on the yield of Miscanthus was unrelated to changes in photosynthetic rates but was achieved mainly by increased canopy leaf area. Vertical measurements through the canopy demonstrated that Miscanthus adapted to the light environment by adjusting leaf morphological and biochemical properties independent of nitrogen treatments. GPP estimated using big leaf and multilayer models varied considerably, suggesting a multilayer model in which V cmax changes both through time and canopy layer could be adopted into agricultural models to more accurately predict biomass production in biomass crop ecosystems.

Inhibitory effect and underlying mechanism of cinnamon and clove essential oils on Botryosphaeria dothidea and Colletotrichum gloeosporioides causing rots in postharvest bagging-free apple fruits

Frontiers in Microbiology (2023)

Dan Wang Guiping Wang Jin‐Zheng Wang Hao Zhai Xiaomin Xue

Bagging-free apple is more vulnerable to postharvest disease, which severely limits the cultivation pattern transformation of the apple industry in China. This study aimed to ascertain the dominant pathogens in postharvest bagging-free apples, to evaluate the efficacy of essential oil (EO) on inhibition of fungal growth, and to further clarify the molecular mechanism of this action. By morphological characteristics and rDNA sequence analyses, Botryosphaeria dothidea ( B. dothidea ) and Colletotrichum gloeosporioides ( C. gloeosporioides ) were identified as the main pathogens isolated from decayed bagging-free apples. Cinnamon and clove EO exhibited high inhibitory activities against mycelial growth both in vapor and contact phases under in vitro conditions. EO vapor at a concentration of 60 μL L −1 significantly reduced the incidence and lesion diameter of inoculated decay in vivo . Observations using a scanning electron microscope (SEM) and transmission electron microscope (TEM) revealed that EO changed the mycelial morphology and cellular ultrastructure and destroyed the integrity and structure of cell membranes and major organelles. Using RNA sequencing and bioinformatics, it was demonstrated that clove EO treatment impaired the cell membrane integrity and biological function via downregulating the genes involved in the membrane component and transmembrane transport. Simultaneously, a stronger binding affinity of trans -cinnamaldehyde and eugenol with CYP51 was assessed by in silico analysis, attenuating the activity of this ergosterol synthesis enzyme. Moreover, pronounced alternations in the oxidation/reduction reaction and critical materials metabolism of clove EO-treated C. gloeosporioides were also observed from transcriptomic data. Altogether, these findings contributed novel antimicrobial cellular and molecular mechanisms of EO, suggesting its potential use as a natural and useful preservative for controlling postharvest spoilage in bagging-free apples.
