The Putative Methyltransferase LAE1 Is Involved in the Regulation of Peptaibols Production in the Biocontrol Fungus SMF2.

The biocontrol fungus SMF2 secretes a large quantity of peptaibols that have been shown to have a range of biological activities and therefore great application values. However, the mechanism of the regulatory expression of peptaibols is still unclear. The putative methyltransferase LaeA/LAE1 is a global regulator involved in the biosynthesis of some secondary metabolites in filamentous fungi.

Enhancing peptaibols production in the biocontrol fungus Trichoderma longibrachiatum SMF2 by elimination of a putative glucose sensor.

Trichoderma spp. are main producers of peptide antibiotics known as peptaibols. While peptaibols have been shown to possess a range of biological activities, molecular understanding of the regulation of their production is largely unclear, which hampers the production improvement through genetic engineering.

[Effects of argon atmosphere at high pressure on electron temperature of laser-induced Cu plasmas].

Copper plasma was induced with a high energy neodymium glass laser(0-25J) beam ablating the Cu target in argon atmosphere. It was observed that the line intensity of the emission spectra increases when the ambient pressure(0.1-0.

[Enhancement effect of argon atmosphere at high pressure on radiation intensity of laser-induced soil plasmas].

In the present paper, the effects of argon atmosphere at high pressure (0. 2-1.1 MPa) on the radiation intensity of the plasma induced by a high energy neodymium glass laser (energy -30 J, pulse width 0.
