Direct Nuclear Delivery of Proteins on Living Plant via Partial Enzymatic Cell Wall Digestion.

Nuclear protein delivery underlies an array of biotechnological and therapeutic applications. While many variations of protein delivery methods have been described, it can still be difficult or inefficient to introduce exogenous proteins into plants. A major barrier to progress is the cell wall which is primarily composed of polysaccharides and thus only permeable to small molecules.

Structure, Absolute Configuration, Antiproliferative and Phytotoxic Activities of Icetexane and Abietane Diterpenoids from and Chemotaxonomic Implications.

From the aerial parts of Zamudio and Bedolla, three new icetexane-type diterpenoids were isolated. Their structures were established through spectroscopic methods and named the following: salvicarranzanolide (), 19-deoxo-salvicarranzanolide () and 19-deoxo-20-deoxy-salvicarranzanolide (). In addition, the known icetexane-type diterpenoids, 6,7,11,14-tetrahydro-7-oxo-icetexone (), -icetexone (), 19-deoxo--icetexone (), icetexone (), 19-deoxo-icetexone () and 7α-acetoxy-6,7-dihydroicetexone (), were also isolated, along with the abietanes sessein () and ferruginol ().

detected in the oral cavity of a dog in Kansas.

is an emerging human fungal pathogen, first described in Japan in 2009, and first detected in the United States in 2016. Here, we report the first-ever description of colonizing a human pet, the first identification of in a non-human mammal in the United States and the first isolate from the state of Kansas. While analyzing the oral mycobiome of dogs from a shelter in Kansas, the oral swab from one dog was found to contain as well as three other fungal species.

Fungal diversity and drug susceptibility of the oral mycobiome of domestic dogs.

The purpose of this study was to characterize the variety and diversity of the oral mycobiome of domestic dogs and to identify the commensal and potentially pathogenic fungi present. Two hundred fifty-one buccal swabs from domestic dogs were obtained and struck onto a chromogenic fungal growth medium that distinguishes between fungal species based on colony color and morphology. After isolating and harvesting single colonies, genomic DNA was extracted from pure cultures.

Transport Across Membranes: Techniques for Measuring Drug Import in Fungal Cells.

The ability of many antifungal molecules to traverse the fungal cell wall and accumulate within the cell is crucial to its ability to have the desired biological activity. Altered accumulation of the drug is an important mechanism of antifungal drug resistance. The best characterized mechanism for altered accumulation is through the action of the drug efflux pump which actively transports the drugs out of the membrane, although this is not the only mechanism for this phenomenon.
