An investigation of Trichoderma biodiversity involving a large-scale environmental gradient was conducted to understand the Trichoderma distribution in China. A total of 3,999 isolates were isolated from forestry, grassland, wetland and agriculture ecosystems, and 50 species were identified based on morphological characteristics and sequence analysis of genetic markers. Trichoderma harzianum showed the largest proportion of isolates and the most extensive distribution. Hypocrea semiorbis, T. epimyces, T. konilangbra, T. piluliferum, T. pleurotum, T. pubescens, T. strictipilis, T. hunua, T. oblongisporum and an unidentified species, Trichoderma sp. MA 3642, were first reported in China. Most Trichoderma species were distributed in Jilin and Heilongjiang Provinces in northeast China and the fewest were distributed in Qinghai Province. Based on the division of ecological and geographic factors, forestry ecosystems and low-altitude regions have the greatest species biodiversity of Trichoderma.

The tripartite motif (TRIM) 22 and mitogen-activated protein kinase (MAPK) signaling pathways play critical roles in the growth of glioblastoma (GBM). However, the molecular mechanism underlying the relationship between TRIM22 and MAPK signaling remains unclear. Here, we found that TRIM22 binds to exon 2 of the sphingosine kinase 2 (SPHK2) gene. An ERK1/2-driven luciferase reporter construct identified TRIM22 as a potential activator of MAPK signaling. Knockout and overexpression of TRIM22 regulate the inhibition and activation of MAPK signaling through the RING-finger domain. TRIM22 binds to Raf-1, a negative regulator of MAPK signaling, and accelerates its degradation by inducing K48-linked ubiquitination, which is related to the CC and SPRY domains of TRIM22 and the C1D domain of Raf-1. In vitro and in vivo, an SPHK2 inhibitor (K145), an ERK1/2 inhibitor (selumetinib), and the nonphosphorylated mutant Raf-1S338A inhibited GBM growth. In addition, deletion of the RING domain and the nuclear localization sequence of TRIM22 significantly inhibited TRIM22-induced proliferation of GBM cells in vivo and in vitro. In conclusion, our study showed that TRIM22 regulates SPHK2 transcription and activates MAPK signaling through posttranslational modification of two critical regulators of MAPK signaling in GBM cells.

<P>Dual ion batteries based on Na<SUP>+</SUP> and PF<SUB>6</SUB><SUP>-</SUP> received considerable attention due to their high operating voltage and the abundant Na resources. Here, cheap and easily obtained graphite that served as a cathode material for dual ion battery delivered a very high average discharge platform (4.52 V vs Na<SUP>+</SUP>/Na) by using sodium hexafluorophosphate in propylene carbonate as electrolyte. Moreover, the all-carbon dual ion batteries with graphite as cathode and hard carbon as anode exhibited an ultrahigh discharge voltage of 4.3 V, and a reversible capacity of 62 mAh·g<SUP>-1</SUP> at 40 mA·g<SUP>-1</SUP>. Phase changes have been investigated in detail through in situ X-ray diffraction and in situ Raman characterizations. The stable structure provides long life cycling performance, and the pseudocapacitance behavior also demonstrates its benefits to the rate capability. Thus, dual ion batteries based on sodium chemistry are very promising to find their applications in future.</P> [FIG OMISSION]</BR>

The subtilisin-like serine protease gene ThSS45 has beencloned from Trichoderma harzianum ACCC30371. Its codingregion is 1302 bp in length, encoding 433 amino acids,with a predicted protein molecular weight of 44.9 kDa andpI of 5.91. ThSS45 was shown by RT-qPCR analysis to bedifferentially transcribed in response to eight different treatments. The transcription of ThSS45 was up-regulated whengrown in mineral medium, under carbon starvation, andnitrogen starvation, and in the presence of 1% root powder,1% stem powder, and 1% leaf powder derived from Populusdavidiana × P. bolleana (Shanxin poplar) aseptic seedlings. The highest increase in transcription approached 3.5-foldthat of the control at 6 h under induction with 1% poplarroot powder. The transcription of ThSS45 was also slightlyup-regulated by 1% Alternaria alternata cell wall and 5% A. alternata fermentation liquid. Moreover, the analyses of codingand promoter regions of ThSS45 homologs indicatedthat serine protease may be involved in both mycoparasitismand antibiotic secretion. ThSS45 was cloned into the pGEX-4T-2 vector and then expressed in Escherichia coli BL21. Therecombinant protein, with an expected molecular weight ofapproximately 69 kDa, was then purified. When transformantBL21-ss was induced with 1 mM IPTG for 6 h, thepurified protease activity reached a peak of 18.25 U/ml atpH 7.0 and 40°C. In antifungal assays the purified proteaseobviously inhibited the growth of A. alternata mycelia.
