Fruit Development, Structure, and Function

24.4K
Fruits form from a mature flower ovary. As seeds develop from the ovules contained within, the ovary wall undergoes a series of complex changes to form fruit. In some fruits, such as soybeans, the ovary wall dries; in other fruits, such as grapes, it remains fleshy. In some cases, organs other than the ovary contribute to fruit formation; such fruits are called accessory fruits.

Genetic Variation01:25

Genetic Variation

1.1K
Genetic variation is the diversity in DNA sequences found among individuals of the same species. This diversity is crucial for a species' survival because it helps organisms adapt to environmental changes. Genetic variation begins with fertilization, where an egg and sperm cell merge. Each of these cells carries 23 chromosomes, up to 46 in the fertilized egg. Chromosomes are long DNA strands that contain genes, the basic units of heredity.
Genes exist in different versions called alleles,...

Genetic Material

3.0K
Within the human body, a complex and detailed system of trillions of cells works in unison to sustain life. Each cell houses a nucleus, which contains 46 chromosomes divided into 23 pairs. Chromosomes are highly coiled structures made of the genetic material DNA. These chromosomes are essential carriers of genetic information, with half inherited from the mother through her egg and the other half from the father's sperm, combining to create the unique genetic makeup of an individual.

In-vitro Mutagenesis

To learn more about the function of a gene, researchers can observe what happens when the gene is inactivated or “knocked out,” by creating genetically engineered knockout animals. Knockout mice have been particularly useful as models for human diseases such as cancer, Parkinson’s disease, and diabetes.

Proteomics01:33

Proteomics

9.0K
A proteome is the entire set of proteins that a cell type produces. We can study proteomes using the knowledge of genomes because genes code for mRNAs, and the mRNAs encode proteins. Although mRNA analysis is a step in the right direction, not all mRNAs are translated into proteins.
Proteomics is the study of proteomes' function. It involves the large-scale systematic study of the proteome to denote the protein complement expressed by a genome. Scientist Mark Wilkins coined the term...

Area of Science:

  • Agronomy
  • Genetics
  • Plant Science

Background:

  • Cultivated peanut (Arachis hypogaea) is a globally significant crop for oil, food, and feed.
  • The USDA peanut germplasm collection comprises 8,982 accessions, with an 812-accession core collection established in the 1990s.
  • Genotyping the core collection provides insights into peanut's genetic diversity and origins.

Purpose of the Study:

  • To genotype the entire peanut core collection using the Arachis_Axiom2 SNP array.
  • To analyze the genotypic diversity, population structure, and biogeography of cultivated peanut.
  • To investigate the origins and dispersal patterns of peanut genetic diversity.

Main Methods:

  • Genotyping of 812 peanut accessions using the Arachis_Axiom2 SNP array, yielding 14,430 informative SNPs.
  • Replication of 253 accessions to assess intra-accessional heterogeneity.
  • Bioinformatic analysis of SNP data to determine genotypic clusters and population structure.

Main Results:

  • Genotypic diversity is primarily structured into five clusters, correlating with botanical variety and market type, but not country of origin.
  • A distinct cluster linked to *hypogaea/aequatoriana/peruviana* varieties, originating from Bolivia, Peru, and Ecuador, suggests early landrace origins.
  • Analysis indicates an early genetic radiation from Southeast Bolivia, followed by South American distribution and global dissemination, retaining significant early diversity.

Conclusions:

  • The genetic diversity of cultivated peanut is largely consistent with an origin in Southeast Bolivia, with subsequent radiation and dispersal.
  • Subgenome exchanges between diploid progenitors have significantly contributed to the genetic diversity of tetraploid peanut.
  • Understanding peanut's genetic structure aids in crop improvement and conservation efforts.
