The present study was conducted to screen a laccase-producing fungal endophyte, optimize fermentation conditions, and evaluate the decolorization ability of the laccase. A new fungal endophyte capable of laccase-producing was firstly isolated from pigeon pea and identified as Myrothecium verrucaria based on a ITS-rRNA sequences analysis. Meanwhile, various fermentation parameters on the laccase production were optimized via response surface methodology (RSM). The optimal fermentation conditions were a fermentation time of five days, temperature 30 °C and pH 6...

The life cycle of bacterial phytopathogens consists of a benign epiphytic phase, during which the bacteria grow in the soil or on the plant surface, and a virulent endophytic phase involving the penetration of host defenses and the colonization of plant tissues. Innovative strategies are urgently required to integrate copper treatments that control the epiphytic phase with complementary tools that control the virulent endophytic phase, thus reducing the quantity of chemicals applied to economically and ecologically acceptable levels...

Fescue toxicosis (FT) results from consumption of tall fescue (Lolium arundinaceum) infected with an endophyte (Epichloë coenophiala) that produces ergot alkaloids (EA), which are considered key etiological agents of FT. Decreased weight gains, hormonal imbalance, circulating cholesterol disruption, and decreased volatile fatty acid absorption suggest toxic (E+) fescue-induced metabolic perturbations. Employing untargeted high-resolution metabolomics (HRM) to analyze E+ grazing-induced plasma and urine metabolome changes, fescue-naïve Angus steers were placed on E+ or non-toxic (Max-Q) fescue pastures and plasma and urine were sampled before, 1, 2, 14, and 28 days after pasture assignment...

Apicidin, an inhibitor of histone deacetylase obtained from the mangrove endophytic fungi Fusarium sp., showed a wide range of antiproliferative activity against various cancer cell lines. Apicidin has also been reported to induce apotosis via Fas/Fas ligand. Yet few studies have focused on mitochondrial pathway for its anti-tumor activity. Here, we evaluated its involved mitochondrial mechanism against lung cancer GLC-82 cells. Its structure was elucidated by MS and NMR spectroscopic data, and comparison of those data with published data...

In this study, the effects of strain Beauveria bassiana (LPSC 1067) as an endophyte in corn plants on consumption, fecundity, and food preference of Dichroplus maculipennis were examined. We observed that the daily consumption by grasshoppers fed with control plants was almost twice that of those that were fed treated plants. Significant differences in fecundity of grasshoppers that were fed with treated plants compared with those that only fed on control plants were also observed. The number of eggs laid per female fed with control plants was 27...

Peperomia obtusifolia, an ornamental plant from the Piperaceae family, accumulates a series of secondary metabolites with interesting biological properties. From a biosynthesis standpoint, this species produces several benzopyrans derived from orsellinic acid, which is a polyketide typically found in fungi. Additionally, the chiral benzopyrans were reported as racemic and/or as diastereomeric mixtures, which raises questions about the level of enzymatic control in the cyclization step for the formation of the 3,4-dihydro-2H-pyran moiety...

Smut fungi are globally distributed plant pathogens that infect agriculturally important crop plants such as maize or potato. To date, molecular studies on plant responses to smut fungi are challenging due to the genetic complexity of their host plants. Therefore, we set out to investigate the known smut fungus of Brassicaceae hosts, Thecaphora thlaspeos. T. thlaspeos infects different Brassicaceae plant species throughout Europe, including the perennial model plant Arabis alpina. In contrast to characterized smut fungi, mature and dry T...

We report the case of a 58-year-old Japanese man with bilateral synchronous renal cell carcinoma (RCC). The diameters of the right and left tumors were 56 and 69 mm, respectively. Both tumors were endophytic. Cryoablation with prophylactic embolization was performed for the left tumor, and 1 month later, a right open partial nephrectomy was performed. No recurrence was observed during a 16-month follow-up, and the serum creatinine level has been stable. The prognosis of bilateral synchronous RCC is better than that of dialysis patients...

The polycyclic aromatic hydrocarbons (PAHs) located on the epidermal tissues showed distinctive toxic effects to root, while the retention and distribution of PAHs on mangrove seedlings poorly understood. Our results confirmed that the partition coefficients (Kf) of the PAHs retained on the epidermal tissue of mangrove roots, such as Kandelia obovata, Avicennia marina and Aegiceras corniculatum, were much higher than the Poaceae plants roots, for example wheat and maize (Wild et al., 2005). Moreover, to the parent and alkyl PAHs, a well negative correlation was observed between the surface polarity of these three species of mangrove root and the Kf values (p < 0...

BACKGROUND: Near-infrared reflectance spectroscopy (NIRS) has been widely used in forage quality control because it is faster, cleaner, and less expensive than conventional chemical procedures. In Lolium perenne (perennial ryegrass), one of the most important forage grasses, the infection by asymptomatic Epichloë fungal endophytes alters the plant nutritional quality due to the production of alkaloids. In this research, we developed a rapid method based on NIRS to detect and quantify endophyte alkaloids (peramine, lolitrem B and ergovaline) using a heterogeneous set of L...

Gregory P Cheplick
PREMISE OF THE STUDY: Genetic resources for forage crops often consist of seeds of specific species and cultivars in cold storage for future use in breeding and selection programs. Temperate grasses such as Lolium perenne, used worldwide for forage and turf, produce seeds commonly infected by hyphae of an endophytic fungus (Epichloë festucae var. lolii). This research determined whether endophytes could persist and infect seedlings of L. perenne emerging from seeds stored for over two decades...
