Summary
Parental care involves avoiding infanticide. This study found that the gene takeout, involved in feeding, is linked to temporal kin recognition in Nicrophorus orbicollis beetles, suggesting co-opted feeding mechanisms facilitate the evolution of parental care.
Area of Science:
- Behavioral Ecology
- Genetics
- Evolutionary Biology
Background:
- Parental care is crucial, yet many species exhibit infanticide before switching to care.
- Temporal kin recognition, where individuals recognize kin based on timing, is a widespread strategy but its evolutionary origins are unclear.
- Co-option of existing mechanisms, like those regulating feeding, may facilitate the evolution of temporal kin recognition.
Purpose of the Study:
- To investigate the role of the gene takeout in temporal kin recognition in Nicrophorus orbicollis.
- To determine if takeout influences the transition from infanticide to parental care.
Main Methods:
- Examined takeout gene expression in Nicrophorus orbicollis beetles.
- Correlated takeout expression with feeding behaviors and parental care decisions (infanticide vs. offspring care).
Main Results:
- Takeout expression was not linked to hunger-driven feeding changes or general parental care transitions.
- Beetles providing care to offspring showed significantly higher takeout expression compared to those committing infanticide.
Conclusions:
- The gene takeout plays a role in temporal kin recognition in Nicrophorus orbicollis.
- These findings support the hypothesis that temporal kin recognition evolves through the co-option of genes regulating feeding behaviors.

943
The gene expression in cells is regulated at different stages: (i) transcription, (ii) RNA processing, (iii) RNA localization, and (iv) translation. Transcriptional regulation is mediated by regulatory proteins such as transcription factors, activators, or repressors—these control gene expression by initiating or inhibiting the transcription of genes. Once a precursor or pre-mRNA is produced, it undergoes post-transcriptional modification, including 5' capping, splicing, and the...

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.

9.9K
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...

In 1928, a German botanist Emil Heitz observed the moss nuclei with a DNA binding dye. He observed that while some chromatin regions decondense and spread out in the interphase nucleus, others do not. He termed them euchromatin and heterochromatin, respectively. He proposed that the heterochromatin regions reflect a functionally inactive state of the genome. It was later confirmed that heterochromatin is transcriptionally repressed, and euchromatin is transcriptionally active chromatin.
