Meeting Abstract S1.3-3 Saturday, Jan. 4 14:30 Epigenetic memory of winter by plants SUNG, SIBUM; Univ. of Texas, Austin sbsung@austin.utexas.edu In a model plant species Arabidopsis, one of key determinants for flowering time is a MADS-box floral repressor, FLOWERING LOCUS C (FLC). FLC is silenced after a sufficient period of winter cold has been perceived (known as […]

Epigenetic Synthesis, or How Environmental Contamination Has Changed the Course of Evolution
Meeting Abstract S1.2-1 Saturday, Jan. 4 09:30 Epigenetic Synthesis, or How Environmental Contamination Has Changed the Course of Evolution CREWS, David; University of Texas at Austin crews@mail.utexas.edu Evolutionary theory accounts for the process of change in life forms. It has had two epochs. The first, Darwinian evolution, established the principle of change through selection. The second, the […]

Epigenetic Mechanisms and Environmental Signals
Meeting Abstract S1.1-2 Saturday, Jan. 4 08:30 Epigenetic Mechanisms and Environmental Signals SOLIMAN, Karam F; Florida A&M University karam.soliman@famu.edu Exposure to specific environmental conditions can alter the epigenome, as the control mechanism of genomic DNA expression, and can lead to long-term phenotypic consequences as certain chronic diseases. These epigenetic changes are plastic and can be altered at […]

Within-clutch Patterns of Yolk Steroids Does Egg Collection Method Matter
Meeting Abstract P3.23 Monday, Jan. 6 15:30 Within-clutch Patterns of Yolk Steroids: Does Egg Collection Method Matter? CASTO, J.M.*; SMITH, A.R.; DE BIASIO, D.; Illinois State University; Illinois State University; Illinois State University jmcasto@ilstu.edu Oviparous vertebrates transfer steroid hormones to egg yolk during folliculogenesis, and these hormones can influence offspring development. In birds, variation in within-clutch patterns […]
