Transcriptome remodeling
nounPronunciation: /ˈtrænskrɪptoʊm ˌriːˈmɑːdəlɪŋ/
The large-scale, coordinated changes in gene expression patterns that occur when plants detect and respond to abiotic stress signals. This involves altered transcription of stress-response genes, metabolic pathway genes, and regulatory genes that collectively reprogram cellular function.
Plain English
The dramatic shifts in which genes are turned on or off inside plant cells when they experience environmental stress.
Etymology & History
Usage
"RNA-sequencing studies reveal extensive transcriptome remodeling within hours of heat stress exposure, affecting thousands of genes across metabolic and regulatory categories."
Style guide notes: Specify the stress type, tissue, time point, and detection method (RNA-seq, microarray, qRT-PCR) when discussing transcriptome remodeling studies.

Frequently Asked Questions
How quickly does transcriptome remodeling occur after stress detection?
Gene expression changes begin within minutes to hours of stress perception through changes in mRNA abundance detectable by RNA-sequencing.
What categories of genes show the greatest transcriptome remodeling during drought?
Genes encoding protective proteins, osmolyte synthesis enzymes, and stress signaling components show the largest expression increases.
Why Test Candidates on This?
Essential for comprehensive understanding of molecular stress response mechanisms and interpretation of genomic-scale stress response studies.
