Summary
Plant transcriptomics reveal that while nanomaterials affect stress genes, their overall impact is minor compared to environmental stressors like drought or salinity. Plants utilize existing stress response pathways for novel nanomaterials.
Area of Science:
- Plant science
- Environmental toxicology
- Genomics
Background:
- Transcriptomics studies investigate nanomaterial toxicity in plants.
- Nanomaterials impact plant stress-responsive genes.
Purpose of the Study:
- To comparatively analyze the overall transcriptional changes induced by nanomaterials in plants.
- To understand plant responses to novel nanomaterials in the context of existing stress pathways.
Main Methods:
- Review of existing transcriptomics studies on nanomaterial-plant interactions.
- Comparative analysis of gene expression data.
Main Results:
- Nanomaterials show a low overall impact on the plant transcriptome.
- Environmental stressors (pathogens, salinity, drought) induce stronger transcriptional responses.
- Plants utilize common regulatory circuits for nanomaterial stress and other abiotic stresses.
- Inhibition of root development and pathogen response genes is a shared effect with abiotic stress.
Conclusions:
- Plants do not possess specific evolved responses to novel nanomaterials.
- Existing stress response pathways are co-opted to manage nanomaterial exposure.
- Nanomaterial toxicity assessment requires considering their impact relative to natural environmental challenges.

02:13Overview of Transposition and Recombination
17.7K
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...

23.2K
Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...

6.7K
RNA interference (RNAi) is a cellular mechanism that inhibits gene expression by suppressing its transcription or activating the RNA degradation process. The mechanism was discovered by Andrew Fire and Craig Mello in 1998 in plants. Today, it is observed in almost all eukaryotes, including protozoa, flies, nematodes, insects, parasites, and mammals. This precise cellular mechanism of gene silencing has been developed into a technique that provides an efficient way to identify and determine the...

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.
