Plant Breeding and Biotechnology

19.7K
Crop cultivation has a long history in human civilization, with records showing the cultivation of cereal plants beginning at around 8000 BC. This early plant breeding was developed primarily to provide a steady supply of food.

Viral Recombination00:57

Viral Recombination

23.7K
Cells are sometimes infected by more than one virus at once. When two viruses disassemble to expose their genomes for replication in the same cell, similar regions of their genomes can pair together and exchange sequences in a process called recombination. Alternatively, viruses with segmented genomes can swap segments in a process called reassortment.

Gene Flow

Gene flow is the transfer of genes among populations, resulting from either the dispersal of gametes or from the migration of individuals.

Causality in Epidemiology01:21

Causality in Epidemiology

752
Causality or causation is a fundamental concept in epidemiology, vital for understanding the relationships between various factors and health outcomes. Despite its importance, there's no single, universally accepted definition of causality within the discipline. Drawing from a systematic review, causality in epidemiology encompasses several definitions, including production, necessary and sufficient, sufficient-component, counterfactual, and probabilistic models. Each has its strengths and...

Single Nucleotide Polymorphisms-SNPs

15.7K
A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...

Summary

A history of rice farming fostered tight social norms and low-mobility networks, enabling societies to better control COVID-19. Rice-farming nations experienced significantly fewer deaths compared to non-rice farming nations.

Area of Science:

  • Cross-cultural psychology
  • Sociology
  • Public health

Background:

  • Global health preparedness rankings in 2019 did not predict COVID-19 control effectiveness.
  • Many lower-income nations demonstrated superior COVID-19 containment compared to wealthier nations.
  • Existing preparedness metrics overlooked crucial cultural factors influencing pandemic response.

Purpose of the Study:

  • To investigate the impact of historical agricultural practices on societal COVID-19 outcomes.
  • To explore the link between traditional rice farming and the development of tight social norms and low-mobility networks.
  • To determine if cultural factors derived from rice cultivation predict pandemic control efficacy globally.

Main Methods:

  • Comparative analysis of rice- and wheat-farming prefectures within China (Study 1).
  • Cross-cultural global study examining the correlation between rice farming heritage and COVID-19 outcomes (Study 2).
  • Statistical analysis of social norms, relationship mobility, and pandemic mortality rates.

Main Results:

  • Rice-farming regions exhibit significantly tighter social norms and less mobile social networks.
  • These cultural characteristics strongly predict better COVID-19 containment.
  • Nations with a history of rice farming experienced 97% fewer COVID-19 deaths than non-rice farming nations.

Conclusions:

  • Historical rice cultivation is a significant predictor of effective COVID-19 control through cultural mechanisms.
  • Societal structures shaped by rice farming facilitated better pandemic coordination and outcomes.
  • Cultural dimensions, often overlooked, are critical for understanding global pandemic response variations.
