Summary
Flowering plants (angiosperms) show rapid gene expression changes, especially in genes responding to stimuli. This rapid evolution drives their ecological success and speciation.
Area of Science:
- Evolutionary biology
- Molecular biology
- Genomics
Background:
- Angiosperms exhibit rapid diversification.
- Molecular mechanisms of angiosperm speciation are not fully understood.
Purpose of the Study:
- Analyze developmental transcriptomes of seven angiosperm species.
- Investigate molecular mechanisms of angiosperm speciation and diversification.
Main Methods:
- Developmental transcriptome analysis across seven angiosperm species.
- Comparative analysis of protein-coding gene expression patterns.
Main Results:
- Angiosperm protein-coding gene expression patterns diverged rapidly over 160 million years.
- Genes involved in stimulus response showed particularly high rates of expression change.
- Expression divergence rates differ from those observed in mammals.
Conclusions:
- Rapid gene expression changes, particularly in stimulus-response genes, are linked to angiosperm ecological success and speciation.
- Ecological and evolutionary dynamics are highly interrelated in angiosperms.
- Provides a resource for cross-kingdom transcriptome evolution studies.

The genomes of eukaryotes are punctuated by long stretches of sequence which do not code for proteins or RNAs. Although some of these regions do contain crucial regulatory sequences, the vast majority of this DNA serves no known function. Typically, these regions of the genome are the ones in which the fastest change, in evolutionary terms, is observed, because there is typically little to no selection pressure acting on these regions to preserve their sequences.

Overview
Transcription is the process of synthesizing RNA from a DNA sequence by RNA polymerase. It is the first step in producing a protein from a gene sequence. Additionally, many other proteins and regulatory sequences are involved in the proper synthesis of messenger RNA (mRNA). Regulation of transcription is responsible for the differentiation of all the different types of cells and often for the proper cellular response to environmental signals.

01:22Diversity in Cell Signaling Responses
7.7K
The physiological function of a cell and cellular communication are outcomes of a range of extrinsic signals, intracellular signaling pathways, and cellular responses. No two cell types express the same repertoire of signaling components. Receptors are highly selective for their cognate ligands, but once activated, they can alter multiple cellular processes such as DNA transcription, protein synthesis, and metabolic activity.

18.8K
Transposons make up a significant part of genomes of various organisms. Therefore, it is believed that transposition played a major evolutionary role in speciation by changing genome sizes and modifying gene expression patterns. For example, in bacteria, transposition can lead to conferring antibiotic resistance. Movement of transposable elements within the genetic pool of pathogenic bacteria can aid in transfer of antibiotic-resistant genetic elements. In eukaryotes, transposons can carry out...

Recombinant DNA technology called transgenesis is often used to add a foreign gene or remove a detrimental gene from an organism. Such genetically modified organisms are called transgenic organisms.
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...
