Gene expression changes induced by space flight in single-cells of the fern Ceratopteris richardii

  title={Gene expression changes induced by space flight in single-cells of the fern Ceratopteris richardii},
  author={Mari L. Salmi and Stanley J. Roux},
This work describes a rare high-throughput evaluation of gene expression changes induced by space flight in a single plant cell. The cell evaluated is the spore of the fern Ceratopteris richardii, which exhibits both perception and response to gravity. cDNA microarray and Q RT-PCR analysis of spores germinating in microgravity onboard NASA space shuttle flight STS-93 revealed changes in the mRNA expression of roughly 5% of genes analyzed. These gene expression changes were compared with gene… 

ARG1 Functions in the Physiological Adaptation of Undifferentiated Plant Cells to Spaceflight.

Most of the genes altered in expression in spaceflight in WT cells were found to be Arg1-dependent, suggesting a major role for that gene in the physiological adaptation of undifferentiated cells to spaceflight.

Transcriptional response of Arabidopsis seedlings during spaceflight reveals peroxidase and cell wall remodeling genes associated with root hair development.

Long-term exposure to microgravity negatively impacts tip growth by repressing expression of genes essential for normal root hair development, which has profound implications for plant adaptation to micro gravity given the importance of tip growing cells such as root hairs for efficient nutrient capture.

Spaceflight engages heat shock protein and other molecular chaperone genes in tissue culture cells of Arabidopsis thaliana.

It is concluded that nondifferentiated cells do indeed sense their gravity environment and HSP genes are induced only in response to prolonged microgravity or simulated microgravity conditions.

Organ-specific remodeling of the Arabidopsis transcriptome in response to spaceflight

The data presented here illustrate that in the absence of gravity plants rely on other environmental cues to initiate the morphological responses essential to successful growth and development, and that the basis for that engagement lies in the differential expression of genes in an organ-specific manner that maximizes the utilization of these signals.

Gene expression changes in Arabidopsis seedlings during short- to long-term exposure to 3-D clinorotation

Seedlings of Arabidopsis thaliana were used to evaluate dynamic transcriptional-level genome responses to simulated microgravity condition created by 3-D clinorotation and qRT-PCR results showed that the expression patterns of the genes (molecular response) were generally similar to the physiological response patterns detected in stress-challenged plants.

Transcriptomic Analysis Reveals the Effects of Microgravity on Rice Calli on Board the Chinese Spaceship Shenzhou 8

The relationship between the variation in the cell wall and plant cell growth under microgravity is discussed and the effects of microgravity on the plant cell wall is focused on.

Transcriptome analyses of Arabidopsis thaliana seedlings grown in space: implications for gravity-responsive genes

The transcriptome of seedlings was analyzed from experiments performed on the International Space Station to study the interacting effects of light and gravity on plant tropisms and identified several genes involved in regulating cell polarity, cell-wall development, oxygen status, and cell defense or stress.

Expression of stress-related genes in zebrawood (Astronium fraxinifolium, Anacardiaceae) seedlings following germination in microgravity

Seeds of a tropical tree species from Brazil, Astronium fraxinifolium, or zebrawood, were germinated, for the first time in microgravity, aboard the International Space Station for nine days, and the subtracted library derived from microgravity-treated seedlings was enriched in known microgravity stress-related ESTs.

Transcription Profiling of the Early Gravitropic Response in Arabidopsis Using High-Density Oligonucleotide Probe Microarrays1,212

This study revealed the induction of complex gene expression patterns as a consequence of gravitropic reorientation and points to an interplay between the grav itropic and mechanical responses and to the extreme sensitivity of plants to even very gentle mechanical perturbations.

Arabidopsis gene expression patterns are altered during spaceflight

Influence of gravity and light on the developmental polarity of Ceratopteris richardii fern spores

Spores of C. richardii are the first documented to have their polarity influenced by gravity, and this influence is slight and is secondary to that of gravity.

Conserved features of germination and polarized cell growth: a few insights from a pollen-fern spore comparison.

The interplay of calcium, nitric oxide and other effectors in both pollen and fern spores suggests certain signalling pathways became important regulators of germination and growth early in the evolution of land plants.

The Fast and Transient Transcriptional Network of Gravity and Mechanical Stimulation in the Arabidopsis Root Apex1[w]

The whole-genome microarray analysis of Arabidopsis root apices after gravity stimulation (reorientation) and mechanical stimulation and transcript levels monitored revealed rapid, transient changes in the relative abundance of specific transcripts occurred in response to gravity or mechanical stimulation, and these transcript level changes reveal clusters of coordinated events.

The Dynamics of Seedling and Cotyledon Cell Development in Arabidopsis thaliana During Reserve Mobilization

Data on increasing size, relatively constant microbody numbers and shape, and absence of observable microbody destruction during the presumptive glyoxysome-peroxisome transition period support the "interconversion model" of microbody ontogeny.

Mechanical culture conditions effect gene expression: gravity-induced changes on the space shuttle.

It is determined which genes mediate three-dimensional culture of cell and tissue aggregates in the low-shear stress, low-turbulent environment of actual microgravity.
