Abstract
No effective fungicides are available for the management of Verticillium dahliae, which causes vascular wilt disease. In this study, a star polycation (SPc)-based nanodelivery system was used for the first time to develop a thiophanate-methyl (TM) nanoagent for the management of V. dahliae. SPc spontaneously assembled with TM through hydrogen bonding and Van der Waals forces to decrease the particle size of TM from 834 to 86 nm. Compared to TM alone, the SPc-loaded TM further reduced the colony diameter of V. dahliae to 1.12 and 0.64 cm, and the spore number to 1.13 × 108 and 0.72 × 108 cfu/mL at the concentrations of 3.77 and 4.71 mg/L, respectively. The TM nanoagents disturbed the expression of various crucial genes in V. dahliae, and contributed to preventing plant cell-wall degradation and carbon utilization by V. dahliae, which mainly impaired the infective interaction between pathogens and plants. TM nanoagents remarkably decreased the plant disease index and the fungal biomass in the root compared to TM alone, and its control efficacy was the best (61.20 %) among the various formulations tested in the field. Furthermore, SPc showed negligible acute toxicity toward cotton seeds. To the best of our knowledge, this study is the first to design a self-assembled nanofungicide that efficiently inhibits V. dahliae growth and protects cotton from the destructive Verticillium wilt.

Abstract
The Burst of expression from polyhedrin (polh) promoter during very late phase of baculovirus infection requires a sequence located between TAAG and the translation initiation site, typically referred to as burst sequence (BS). The expression of polh promoter is stimulated by specifically binding of very late transcriptional factor 1 (VLF-1) to BS. In order to enhance the production of recombinant proteins the polh promoter was modified via a multiple BS bacmid system in which the number of BSs was increased. Compared to an expression from a normal polh promoter, β-glucuronidase (GUS) activity in High Five insect cells was three times higher with a modified polh promoter containing two BSs. Using a modified polh promoter that contains nine BSs in silkworm expression system, β1-3-N-acetylglucosaminyltransferase 2 (β3GnT2) activity per larva was 6.8-fold higher than control. Furthermore, the co-expression of modified promoters along with VLF-1-enhanced β3GnT activity. Thus, an increased optimal number of BS and its co-expression with VLF-1 leads to the production of higher level of gene expression in insect cells and silkworm larvae. This new modified promoter engineered in the current study is the strongest promoter for overexpressing foreign proteins in an eukaryotic cell and system, thus leading a progress in baculovirus-insect cell and silkworm biotechnology.

Abstract
Aspergillus oryzae penicillin biosynthetic genes were clustered. The penicillin production was positively regulated by VeA, a global gene regulator required for transcriptional expression of the penicillin biosynthetic genes. Overexpression of the biosynthetic genes by a strong promoter yielded a greater than 100-fold increase in penicillin production.

Abstract
AIM To develop an overexpression system in Aspergillus aculeatus in order to establish an efficient overproduction method of beta-mannosidase (MANB). METHODS AND RESULTS An overexpression plasmid for the manB gene, encoding A. aculeatus MANB, was constructed and introduced into A. aculeatus cells. The gene was overexpressed under an improved promoter containing 12 copies of Region III cis-elements of Aspergillus oryzae in the transformant, and it secreted 2.56 mg MANB ml(-1) in liquid culture, which obtained a 9.4-fold higher productivity than that achieved in an overexpression system in A. oryzae. Most of the secreted protein in the cultured medium of the transformed A. aculeatus was the overproduced enzyme. CONCLUSIONS Aspergillus aculeatus with the introduced overexpression plasmid produced 2.56 mg MANB ml(-1) in cultured medium. The improved promoter with A. oryzae Region III functioned in A. aculeatus; thus the strain is an expectant host for recombinant protein productions. SIGNIFICANCE AND IMPACT OF THE STUDY The overexpression system with the improved promoter in A. aculeatus brought the highest productivity of MANB reported to date. The expression system would be a strong bioindustrial tool for protein production.
