Nsa, Imade Yolanda (2013-08-13)Circadian clocks are composed of molecular oscillators and are found in most eukaryotes and some prokaryotes. The fungus Neurospora crassa is a leading model for studying the clock. In N. crassa, the well-described FRQ/WCC ...
-
Greene, Andrew Vanderford (Texas A&M University, 2006-10-30)Circadian rhythms in biological processes occur in a wide range of organisms and are generated by endogenous oscillators. In Neurospora crassa, the FRQ-oscillator (comprised of FRQ, WC-1 and WC-2) is essential for rhythms ...
-
Topo, Elias Jordan (2019-04-23)The circadian clock regulates the rhythmic expression of roughly half of the eukaryotic genome at the level of mRNA abundance. However, little is known about how rhythmic phase is regulated (Delaunay & Laudet, 2002). ...
-
Greenwell, Ben Jefferson (2020-04-20)Nearly every mammalian cell exhibits daily rhythms in gene expression, which guide the activation of tissue-specific processes across the day. Rhythms in peripheral tissues are synchronized by neuronal and hormonal rhythmic ...
-
Kumar, Krithika (2012-02-14)Many multicellular cyanobacteria produce specialized nitrogenfixing heterocysts. During diazotrophic growth of Anabaena (Nostoc) sp. strain PCC 7120, a regulated developmental pattern of single heterocysts separated by ...
-
Goldsmith, Charles Sidney (2013-08-12)Mitogen activated protein kinase (MAPK) pathways are conserved biochemical signal transduction pathways in eukaryotic organisms. These signaling pathways demonstrate great versatility in their ability to detect various ...
-
Draheim, Roger Russell (2009-05-15)Environmental signals are sensed by membrane-spanning receptors that communicate with the cell interior. Bacterial chemoreceptors modulate the activity of the CheA kinase in response to binding of small ligands or upon ...
-
Kozhina, Elena (2010-07-14)In Drosophila, XX embryos express Sxl from the early promoter, SxlPe, and become females. At the same time, XY embryos with only one X chromosome become males. I investigated the role of repression in the establishment of ...
-
Karaganis, Stephen Paul (2009-05-15)Avian circadian clocks are composed of a distributed network of neural and peripheral oscillators. Three neural pacemakers, located in the pineal, the eyes, and the hypothalamus, control circadian rhythms of many biological ...
-
Lee, Soo Chan (2009-05-15)Polarized hyphal growth dominates the life cycle of filamentous fungi and is essential to disease progression for many fungal pathogens. Despite its importance, much of the basic biology controlling the process remains to ...
-
Ramirez, Manuel Antonio (2021-04-22)The circadian clock is a conserved endogenous time keeping mechanism that controls up to half of the eukaryotic genome at the level of transcript abundance. In addition to clock control of transcript abundance, our lab ...
-
Caster, Stephen Z (2016-08-01)Stress response pathways function to allow cells to adapt to changes in the environment. In Neurospora crassa, acute osmotic stress activates the conserved p38-like osmosensing mitogen-activated protein kinase (OS MAPK) ...
-
Shen, Lunda (2021-12-07)Ribosomes translate RNA into proteins. The protein synthesis inhibitor cycloheximide (CHX) is widely used to inhibit eukaryotic ribosomes engaged in translation elongation. However, the lack of structural data for actively ...
-
Xie, Xin (Texas A&M University, 2004-11-15)The orange bread mold Neurospora crassa is a useful model for the study of filamentous fungi. One of the asexual reproduction cycles in N. crassa, macroconidiation, can be induced by several environmental cues, including ...
-
Vitalini, Michael William (2009-05-15)The ubiquity of circadian systems has allowed their characterization in a broad range of model systems, which has greatly improved knowledge of how these systems are organized and the vast range of cellular and organismal ...
-
Petty, Amanda Lee (2018-05-23)The circadian clock is a conserved mechanism that allows organisms to coordinate their daily physiology and behavior with 24-hour environmental cycles. The pervasiveness of the circadian clock is evident in that roughly ...
-
Dekhang, Rigzin N (2015-05-05)The Neurospora crassa circadian clock is based on a highly regulated molecular negative feedback loop, similar to molecular clocks in all eukaryotes. A core component of the N. crassa molecular clock is the White Collar ...
-
Ibarra, Oneida (2017-12-12)The circadian clock is an evolutionary conserved time-keeping mechanism that, through the regulation of rhythmic gene expression, coordinates the physiology of an organism with daily environmental cycles. Clock-controlled ...
-
Cheng, Clint (2015-05-07)Lignocellulosic biomass is an attractive source of renewable energy. Saccharomyces cerevisiae is often a biocatalyst of choice because of its ability to produce ethanol, as well as its robustness to harsh processing ...
-
Shirley, Morgan (2014-06-06)A history and detailed account of the applications of β-lactones towards natural products and bioactive compounds in the last ten years is discussed as these small heterocycles are becoming more widely recognized for their ...
