Nematode-trapping fungi are "carnivorous" and attack their hosts using specialized trapping devices. The morphological development of these traps is the key indicator of their switch from saprophytic to predacious lifestyles. Here, the genome of the nematode-trapping fungus Arthrobotrys oligospora Fres. (ATCC24927) was reported. The genome contains 40.07 Mb(More)
Several bacterial species are capable of using nicotine, the main alkaloid in tobacco plants, as a substrate for growth. The dominant species include members of two genera, Pseudomonas and Arthrobacter. The degradation pathway and genetic structure of nicotine catabolism in Arthrobacter nicotinovorans were recently reviewed (Brandsch Appl Microbiol(More)
Lecanicillium psalliotae produced an extracellular protease (Ver112) which was purified to apparent homogeneity giving a single band on SDS-PAGE with a molecular mass of 32 kDa. The optimum activity of Ver112 was at pH 10 and 70 °C (over 5 min). The purified protease degraded a broad range of substrates including casein, gelatin, and nematode cuticle with(More)
Epithelial-to-mesenchymal transition (EMT) plays an important role in renal interstitial fibrosis (RIF) with diabetic nephropathy (DN). Smad7 (a inhibitory smad), a downstream signaling molecules of TGF-β1, represses the EMT. The physiological function of miR-21 is closely linked to EMT and RIF. However, it remained unclear whether miR-21 over-expression(More)
To better exploit the biocontrol potential of nematophagous fungi, it is important to fully understand the molecular background of the infection process. In this paper, several nematode-trapping fungi were surveyed for nematocidal activity. From the culture filtrate of Monacrosporium microscaphoides, a neutral serine protease (designated Mlx) was purified(More)
OBJECTIVES To evaluate the efficacy and safety of linagliptin in Chinese patients with type 2 diabetes mellitus (T2DM) inadequately controlled by metformin and sulphonylurea. RESEARCH DESIGN AND METHODS Data for a pre-defined Chinese subgroup who participated in a Phase III randomised, placebo-controlled, 24 week trial (NCT00602472) were analysed. The(More)
MicroRNAs (miRs) play important roles in initiation and progression of many pathologic processes. However, the roles of miRs in diabetic nephropathy remain unclear. This study was to determine whether miR-21 was involved in diabetic nephropathy and to explore the relationship between miR-21 and MMP9/TIMP1 expression in diabetic nephropathy. In situ(More)
Nematophagous fungi are an important group of soil microorganisms that can suppress the populations of plant-parasitic nematodes. The pathogenic mechanisms of nematophagous fungi are diverse: They can be parasitical–mechanical through producing specialized capturing devices, or toxin-dependent. During infections, a variety of virulence factors may be(More)
Subtilisin-like serine proteases play an important role in pathogenic fungi during the penetration and colonization of their hosts. In this study, we perform an evolutionary analysis of the subtilisin-like serine protease genes of subphylum Pezizomycotina to find if there are similar pathogenic mechanisms among the pathogenic fungi with different life(More)
Microorganisms play important roles in the tobacco aging process. However, microbial communities on flue-cured tobacco leaves (FCTL) remain largely unknown. In this study, the total microbial genomic DNA of unaged and aging FCTL from Zimbabwe were isolated using a culture-independent method, and the bacterial communities were investigated through analyzing(More)
