    Abstract: The present invention relates to a technology to provide segmental aneuploidy progeny strains of Trichoderma reesei. In particular, the present invention relates to a method to produce segmental aneuploidy progeny strains of Trichoderma reesei via sexual crossing of two parent haploid strains with chromosome heterozygosity (e.g. one having scaffold M and scaffold 33, the other having scaffold F and scaffold X), preferably at least one of which includes a non-homologous end joining (NHEJ) gene. The present invention also relates to stable, segmental aneuploidy progeny strains of richoderma reesei thus produced which particularly exhibit enhanced gene expression or activities of carbohydrate-active enzymes (CAZymes) and more particularly prevent returning to euploidy for an extended period of time.

    Abstract: The present invention provides a recombinant DNA molecule encoding a fusion protein, comprising a first DNA sequence encoding a high-efficiency transit peptide operably linked to a second DNA sequence encoding a passenger protein, wherein the high-efficiency transit peptide is selected from the group consisting of transit peptides of the precursors of translocon at the inner envelope membrane of chloroplasts 40 kD (prTic40), chaperonin 10-2 (prCpn10-2), Fibrillin 1B (prFibrillin), ATP sulfurylase 1 (prAPS1), ATP sulfurylase 3 (prAPS3), 5′-adenylylsulfate reductase 3 (prAPR3), stromal ascorbate peroxidase (prsAPX), prTic40-E2A (a prTic40 variant), prCpn10-1-ΔC7C37S (a chaperonin 10-1 variant), a functional fragment of any of the transit peptides and an equivalent thereof. And the present invention also provides a method of high efficiency delivery of a protein into plastids using the high-efficiency transit peptides.

    Abstract: A system and method thereof for collecting and concentrating a biologic substance of interest is provided. The biologic of interest obtained from a biologic sample present at an initial low concentration (or low number counts) can be captured and released through a collection device of the system to an intermediate second concentration, and further recovered through a concentration device of the system to a third concentration, thereby facilitating subsequent detection, characterization, enumeration, immunostaining, inspection, imaging, culturing, molecular analysis, and/or other assays.
