Abstract
Putrescine is a low-molecular-weight organic compound that is widely found in pickled foods. Although the intake of biogenic amines is beneficial to humans, an excessive intake can cause discomfort. In this study, the ornithine decarboxylase gene (ODC) was involved in putrescine biosynthesis. After cloning, expression and functional verification, it was induced and expressed in E. coli BL21 (DE3). The relative molecular mass of the recombinant soluble ODC protein was 14.87 kDa. The function of ornithine decarboxylase was analyzed by determining the amino acid and putrescine content. The results show that the ODC protein could catalyze the decarboxylation of ornithine to putrescine. Then, the three-dimensional structure of the enzyme was used as a receptor for the virtual screening of inhibitors. The binding energy of tea polyphenol ligands to the receptor was the highest at -7.2 kcal mol-1. Therefore, tea polyphenols were added to marinated fish to monitor the changes in putrescine content and were found to significantly inhibit putrescine production (p < 0.05). This study lays the foundation for further research on the enzymatic properties of ODC and provides insight into an effective inhibitor for controlling the putrescine content in pickled fish.

Metabolomics of the interaction between a consortium of entomopathogenic fungi and their target insect: Mechanisms of attack and survival. PESTICIDE BIOCHEMISTRY AND PHYSIOLOGY 2023; 191:105369. [PMID: 36963938 DOI: 10.1016/j.pestbp.2023.105369] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/12/2022] [Revised: 02/07/2023] [Accepted: 02/08/2023] [Indexed: 06/18/2023]
Abstract
One of the most concerning pests that attack strawberries in Brazil is Duponchelia fovealis (Zeller), a non-native moth with no registered control methods to date. Our group recently observed that a fungal consortium formed by two strains of Beauveria bassiana (Balsamo) increased the mortality of D. fovealis more than inoculation with each strain on its own. However, the molecular interaction between the fungal consortium and the caterpillars is unknown. Thus, in this work, we sought to pioneer the evaluation of the molecular interaction between a fungal consortium of B. bassiana and D. fovealis caterpillars. We aimed to understand the biocontrol process involved in this interaction and the defense system of the caterpillar. Seven days after D. fovealis were inoculated with the consortium, the dead and surviving caterpillars were analyzed using GC-MS and LC-MS. Some of the metabolites identified in dead caterpillars have primarily antioxidant action. Other metabolites may have insecticidal potential, such as diltiazem-like and tamsulosin-like compounds, as well as 2,5-dimethoxymandelic acid. In surviving caterpillars, the main mechanisms are pro-inflammatory from 2-Palmitoylglycerol metabolite and the antifungal action of the metabolite Aegle marmelos Alkaloid-C. The metabolites identified in dead caterpillars may explain the increased mortality caused by the consortium due to its antioxidant mechanism, which can suppress the caterpillars' immune system, and insecticide action. In surviving caterpillars, the main resistance mechanisms may involve the stimulus to the immunity and antifungal action.

Abstract
Metarhizium species are the most abundant fungi that can be isolated from soil, with a well-known biopesticide capacity. Metarhizium recognizes their hosts when the conidium interacts with insects, where the fungi are in contact with the hydrocarbons of the outermost lipid layer cuticle. These cuticular hydrocarbons comprise a mixture of n-alkanes, n-alkenes, and methyl-branched chains. Metarhizium can degrade insect hydrocarbons and use these hydrocarbons for energy production and the biosynthesis of cellular components. The metabolism of nitroalkanes involves nitronate monooxygenase activity. In this work, we isolated a family of six genes with potential nitronate monooxygenase activity from Metarhizium brunneum. The six genes were expressed in Escherichia coli, and the nitronate monooxygenase activity was verified in the recombinant proteins. Additionally, when the conidia of M. brunneum were grown in medium with nitroalkanes, virulence against Plutella xylostella increased. Furthermore, we analyzed the expression of the six Npd genes during the infection to this insect, which showed differential expression of the six Npd genes during infection.

Abstract
We investigated the colonization potential of five Metarhizium anisopliae isolates on pine tree surfaces under laboratory conditions, determined the influence of the pine bark extract on fungal growth and evaluated the insecticidal activity following colonization on the Japanese pine sawyer. Finally, the effect of colonization on adults pine sawyer was evaluated using the top three performing isolates (JEF-197, JEF-271 and JEF-279) under laboratory and field conditions. As a result, isolate JEF-197 showed the highest conidial production on the pine surfaces, and five isolates, including JEF-197, showed higher hyphal growth on autoclaved pine bark extract agar, compared to a water agar. Pine bark treated with the isolates showed 40-70 % mortality of adults pine sawyer. Under mimicked overwintering conditions, in the JEF-197 treatment group, 40 % of the inserted larvae became adults and all were dead after 59 d. In a field test, colonized isolate JEF-197 also showed 37 % insecticidal activity against emerged adults from the pine logs as overwintering sites. This work suggests that M. anisopliae isolate JEF-197 possibly colonized the pine surface and application of a conidial suspension on the pine logs as overwintering sites could be an effective strategy to control the pine sawyer.

Abstract
Chemical insecticides have been commonly used to control agricultural pests, termites, and biological vectors such as mosquitoes and ticks. However, the harmful impacts of toxic chemical insecticides on the environment, the development of resistance in pests and vectors towards chemical insecticides, and public concern have driven extensive research for alternatives, especially biological control agents such as fungus and bacteria. In this review, the mode of infection of Metarhizium fungus on both terrestrial and aquatic insect larvae and how these interactions have been widely employed will be outlined. The potential uses of Metarhizium anisopliae and Metarhizium acridum biological control agents and molecular approaches to increase their virulence will be discussed.

Abstract
BACKGROUND & AIMS Biliary epithelial cells (BECs) are considered to be a source of regenerating hepatocytes when hepatocyte proliferation is compromised. However, there is still controversy about the extent to which BECs can contribute to the regenerating hepatocyte population, and thereby to liver recovery. To investigate this issue, we established a zebrafish model of liver regeneration in which the extent of hepatocyte ablation can be controlled. METHODS Hepatocytes were depleted by administration of metronidazole to Tg(fabp10a:CFP-NTR) animals. We traced the origin of regenerating hepatocytes using short-term lineage-tracing experiments, as well as the inducible Cre/loxP system; specifically, we utilized both a BEC tracer line Tg(Tp1:CreER(T2)) and a hepatocyte tracer line Tg(fabp10a:CreER(T2)). We also examined BEC and hepatocyte proliferation and liver marker gene expression during liver regeneration. RESULTS BECs gave rise to most of the regenerating hepatocytes in larval and adult zebrafish after severe hepatocyte depletion. After hepatocyte loss, BECs proliferated as they dedifferentiated into hepatoblast-like cells; they subsequently differentiated into highly proliferative hepatocytes that restored the liver mass. This process was impaired in zebrafish wnt2bb mutants; in these animals, hepatocytes regenerated but their proliferation was greatly reduced. CONCLUSIONS BECs contribute to regenerating hepatocytes after substantial hepatocyte depletion in zebrafish, thereby leading to recovery from severe liver damage.

Abstract
Metarhizium robertsii is an entomopathogenic fungus that is also plant rhizosphere competent. Two adhesin-encoding genes, Metarhizium adhesin-like protein 1 (Mad1) and Mad2, are involved in insect pathogenesis or plant root colonization, respectively. Here we examined the differential expression of the Mad genes when grown on a variety of soluble (carbohydrates and plant root exudate) and insoluble substrates (locust, tobacco hornworm, and cockroach cuticle, chitin, tomato stems, cellulose, and starch) and during insect, Plutella xylostella, infection. On insect cuticles Mad1 was up regulated, whereas bean root exudate and tomato stems resulted in the up regulation of Mad2. During the early stages of insect infection Mad1 was expressed while Mad2 was not expressed until fungal hyphae emerged and conidiated on the insect cadaver. The regulation of Mad2 was compared to that of other stress-related genes (heat shock protein (Hsp)30, Hsp70, and starvation stress gene A (ssgA)). Mad2 was generally up regulated by nutrient starvation (similar to ssgA) but not by pH, temperature, oxidative or osmotic stresses. Whereas Hsp30 and Hsp70 were generally up regulated at 37 °C or by oxidative stress even under nutrient enriched conditions. We fused the promoter of the Mad2 gene to a marker gene (green fluorescent protein (GFP)) and confirmed that Mad2 was up regulated when M. robertsii was grown in the presence of nutrient starvation. Examination of the promoter region of Mad2 revealed that it possessed two copies of a stress-response element (STRE) known to be regulated under the general stress-response pathway.
