We also used microarray analysis to examine transcriptomic changes under moderate drought, identifying thousends of genes that potentially mediate moderate drought responses in the flower, including genes encoding transcription factors that likely play crucial regulatory roles.
Moderate drought causes dramatic floral transcriptomic reprogramming to ensure successful reproductive development in Arabidopsis.

View SamplesCircadian rhythms are oscillations with a periodicity of 24 hours that are controlled by an endogenous clock and are observed in virtually all aspects of mammalian function from expression of genes to complex physiological processes. The master clock is present in the suprachiasmatic nucleus (SCN) in the anterior part of the hypothalamus and controls peripheral clocks present in other parts of the body . Although much is known about the mechanism of the central clock in the SCN, the regulation of clocks present in peripheral tissues is still unclear. This study is designed to examine fluctuations in gene expression in lungs within the 24 hour circadian cycle in normal animals. The objectives of this study is to identify and analyze circadian oscillation in gene expression in lungs, and to identify the role of circadian regulation in coordinating the functioning of this dynamic organ.

View SamplesInduced pluripotent stem cells (iPSCs) offer opportunity for insight into the genetic requirements of the X chromosome for somatic and germline development. Turner syndrome is caused by complete or partial loss of the second sex chromosome; while more than 90% of Turner cases result in spontaneous fetal loss, survivors display an array of somatic and germline clinical characteristics. Here, we derived iPSCs from Turner syndrome and control individuals and examined germ cell development as a function of X chromosome composition. We analyzed gene expression profiles of derived iPSCs and in vitro differentiated cells by single cell qRT-PCR and RNA-seq. We whoed that two X chromosomes are not necessary for reprogramming or pluripotency maintenance. Genes that escape X chromosome inactivation (XCI) between control iPSCs and those with X chromosome aneuploidies revealed minimal expression differences relative to a female hESC line. Moreover, when we induced germ cell differentiation via murine xenotransplantation of iPSC lines into the seminiferous tubules of busulfan-treated mice, we observed that undifferentiated iPSCs, independent of X chromosome composition, when placed within the correct somatic environment, are capable of forming early germ cells in vivo. Results indicate that two intact X chromosomes are not required for germ cell formation; however, clinical data suggest that two sex chromosomes are required for maintenance of human germ cells.
