Efficacy of Trichoderma asperellum TC01 against anthracnose and growth promotion of Camellia sinensis seedlings

In this study, we investigated the role of Trichoderma asperellum TC01 in the regulation of C. sinensis growth and the activation of defence responses against Colletotrichum gloeosporioides C62 by developing a biocontrol–plant–pathogen interaction system. When C. sinensis was co-cultivated with T. asperellum TC01, it was able to reduce 58.37% of disease severity compared with other treatments. Furthermore, compared with control plant growth, T. asperellum TC01-treated plants showed an increase in shoot height (7.5%), stem diameter (34.09%), shoot fresh weight (81.18%), root fresh weight (93.75%), shoot dry weight (85.71%) and root dry weight (115.38%) at 45 days after inoculation under greenhouse conditions. RNA sequencing analysis revealed that 48 hours after inoculation, key genes were up-regulated in the flavonoid biosynthesis pathway of TC01-treated plants (T4) and down-regulated in leaves of C. gloeosporioides C62-treated plants compared with that of the control plants, indicating that TC01 triggers flavonoid and phenylpropanoid pathways during the early stages of the interaction with C. sinensis. Furthermore, higher expression levels of genes associated with the jasmonic acid and ethylene signalling pathway in the roots of TC01- and C62-treated plants (T3) than in either TC01- or C62-treated plants, indicated that TC01 triggered the induced systemic response in C. sinensis. Genes involved in the flavonoid, phenylpropanoid, jasmonic acid and ethylene play an ...

Authors: Labony SS, Alim MA, Hasan MM, Hossain MS, Islam A, Alam MZ, Tsuji N, Anisuzzaman Abstract Fish-borne liver and intestinal flukes are helminth pathogens that have a negative impact on public health worldwide. We herein investigated the status of infection by the metacercariae (MC) of fish-borne trematodes (FBTs) in randomly selected freshwater wild fishes. Five species of fishes were collected and digested artificially using digestion fluid to recover MC. All fish species, namely, ticto barb (Puntius ticto) (14/16, 87.5%), banded gourami (Colisa fasciata) (8/12, 66.7%), freshwater garfish (Xenentodon cancil...

CONCLUSIONS: The developed LC/APCI-MS-SRM method for detecting CVC before the symptoms appear is simple and accurate. It is inexpensive, and many samples can be screened per hour using 1 mg of leaves. Knowledge of the influence of the rootstock on the chemical profile of the graft is limited. This study demonstrates the effect of the rootstock in synthesizing flavonoids and increasing its content in all parts of the graft. PMID: 32053855 [PubMed - as supplied by publisher]

This study was to assess the anti-inflammatory potential of exopolysaccharide (EPS) produced by a medicinal fungus Cordyceps sinensis Cs-HK1. The EPS was isolated from the Cs-HK1 mycelial fermentation broth by ethanol precipitation and purified by deproteinization and dialysis. The EPS had a total sugar content of 74.8% and a maximum average molecular weight (MW) over 107 Da, and consisted of mainly glucose and mannose, and a small amount of galactose and ribose. In THP-1 and RAW264.7 cell cultures, EPS significantly inhibited lipopolysaccharide (LPS)-induced inflammatory responses of the cells including the release of N...

Abstract Clonorchis sinensis infection is caused by ingestion of raw freshwater fish containing the infective larvae of Clonorchis sinensis. It is highly endemic in East Asia, especially in China. Selective chemotherapy of people who report habitual eating of raw freshwater fish is a control measure. As the performance of this screening technique has not yet been fully evaluated in China, a cross-sectional study was conducted, covering 16 counties in four major clonorchiasis-endemic provinces. About 1 000 participants were enrolled from each county. In total, 16 230 participants were enrolled from 16 counties. Fae...

In this study, we identified 2 novel CatDs (CsCatD1 and CsCatD2) of Clonorchis sinensis and partially characterized their properties. Both CsCatDs represent typical enzymes sharing amino acid residues and motifs that are tightly conserved in the CatD superfamily of proteins. Both CsCatDs showed similar patterns of expression in different developmental stages of C. sinensis, but CsCatD2 was also expressed in metacercariae. CsCatD2 was mainly expressed in the intestines and eggs of C. sinensis. Sera obtained from rats experimentally infected with C. sinensis reacted with recombinant CsCatD2 beginning 2 weeks after infection ...

Authors: Zhan X, Yeh HY, Shin DH, Chai JY, Seo M, Mitchell PD Abstract As we learn more about parasites in ancient civilizations, data becomes available that can be used to see how infection may change over time. The aim of this study is to assess how common certain intestinal parasites were in China and Korea in the past 2000 years, and make comparisons with prevalence data from the 20th century. This allows us to go on to investigate how and why changes in parasite prevalence may have occurred at different times. Here we show that Chinese liver fluke (Clonorchis sinensis) dropped markedly in prevalence in both Ko...
