Endophytes are microbes that live within plants without causing detectable illness. These microorganisms can emit volatile organic compounds (VOCs), airborne signaling molecules that can significantly affect plant growth. Despite the prevalence of endophytes and their VOCs, little is known about these factors important to plant health. With this in mind I isolated fungal endophytes from leaves of Populus trichocarpa and Populus fremontii, tree species with economic and environmental uses, to determine if endophyte communities are reserved between the closely related tree species and over seasons. Surface sterilized leaf fragments were plated onto malt extract agar and the resulting fungi were …

DAX-1, an orphan nuclear hormone receptor, acts mainly as a repressor through transcriptional protein complexes. Its unique structure and specific expression raises questions as to what its precise interactions are and how it mediates its repressive function. While it is known to play a role in sexual development and adrenal insufficiency, expression in certain types of cancer suggests additional functions and interactions. Knock in of DAX-1 into a low-DAX-1 expressing cancer cell line has been previously observed to increase apoptosis, while, inversely, down in a high-DAX-1 expressing cancer cell line shows a decrease in apoptosis. Target genes that belong to …
