Optimal Foraging00:48

Optimal Foraging

How animals obtain and eat their food is called foraging behavior. Foraging can include searching for plants and hunting for prey and depends on the species and environment.
Exon Recombination02:32

Exon Recombination

The evolution of new genes is critical for speciation. Exon recombination, also known as exon shuffling or domain shuffling, is an important means of new gene formation. It is observed across vertebrates, invertebrates, and in some plants such as potatoes and sunflowers. During exon recombination, exons from the same or different genes recombine and produce new exon-intron combinations, which might evolve into new genes. 
Exon shuffling follows “splice frame rules.” Each exon has three reading...
Combinatorial Gene Control02:33

Combinatorial Gene Control

Combinatorial gene control is the synergistic action of several transcriptional factors to regulate the expression of a single gene. The absence of one or more of these factors may lead to a significant difference in the level of gene expression or repression.
The expression of more than 30,000 genes is controlled by approximately 2000-3000 transcription factors. This is possible because a single transcription factor can recognize more than one regulatory sequence. The specificity in gene...
Cis-regulatory Sequences02:02

Cis-regulatory Sequences

Cis-regulatory sequences are short fragments of non-coding DNA that are present on the same chromosomes as the genes that they regulate. These fragments serve as binding sites for transcriptional regulators, proteins that are responsible for controlling gene transcription and differential gene expression across cell types in eukaryotes. Cis-regulatory sequences can be close to the gene of interest or thousands of bases away in the DNA sequence; however, those sequences that are further away are...
Reporter Genes02:11

Reporter Genes

Reporter genes are a type of protein-coding gene that are often tagged to a gene of interest. Once inside a target cell, reporter genes usually produce visually identifiable characteristics like fluorescence and luminescence when expressed along with the gene of interest. Thus, reporter genes “report” the presence or absence of genes of interest in an organism, determine the gene expression pattern, or track the physical location of a DNA segment or protein in the cell.
Commonly used reporter...

Area of Science:

  • Neuroscience
  • Genetics
  • Behavioral Ecology

Background:

  • Behavioral plasticity, the ability to alter behavior in response to environmental changes, is crucial for survival.
  • The desert locust (Schistocerca gregaria) exhibits extreme behavioral plasticity, known as phase polyphenism, shifting from solitary to gregarious behavior.
  • The molecular mechanisms underlying locust phase polyphenism are largely unknown.

Purpose of the Study:

  • To investigate the role of the foraging (for) gene, which encodes a cGMP-dependent protein kinase (PKG), in locust behavior.
  • To identify and characterize the locust for gene and its expression patterns in the brain.
  • To explore the potential link between PKG activity and locust phase-related behaviors.

Main Methods:

  • Identification and cloning of the desert locust for gene.
  • Analysis of phylogenetic relationships between locust PKG and other insect PKGs.
  • Study of for gene expression in the locust brain using immunohistochemistry.

Main Results:

  • The locust for gene was identified and cloned.
  • Phylogenetic analysis placed the locust PKG within the broader insect PKG family.
  • FOR expression was localized to specific neurons in the anterior midline of the locust brain (pars intercerebralis).

Conclusions:

  • The study provides foundational insights into the locust for gene and its neural expression.
  • Differences in PKG enzyme activity may correlate with distinct phase-related behaviors in locusts.
  • These findings pave the way for future functional studies on the for gene's role in locust phase polyphenism.
