Genomic Imprinting and Inheritance

37.1K
Diploid organisms inherit genetic material through chromosomes from both parents. Copies of the same gene are known as alleles. In most cases, both alleles are simultaneously expressed and allow various cellular processes to function optimally. If one of the alleles is missing or mutated, the expression of the other allele can compensate; however, this is not true for all genes.
The expression of some genes depends on which parent passed the gene to the offspring, through a phenomenon known as...

In 1866, Gregor Mendel published the results of his pea plant breeding experiments, providing evidence for predictable patterns in the inheritance of physical characteristics. The significance of his findings was not immediately recognized. In fact, the existence of genes was unknown at the time. Mendel referred to hereditary units as “factors.”

Epigenetics is the study of inherited changes in a cell's phenotype without changing the DNA sequences. It provides a form of memory for the differential gene expression pattern to maintain cell lineage, position-effect variegation, dosage compensation, and maintenance of chromatin structures such as telomeres and centromeres. For example, the structure and location of the centromere on chromosomes are epigenetically inherited. Its functionality is not dictated or ensured by the underlying...

Non-nuclear Inheritance01:29

Non-nuclear Inheritance

23.1K
Most DNA resides in the nucleus of a cell. However, some organelles in the cell cytoplasm⁠—such as chloroplasts and mitochondria⁠—also have their own DNA. These organelles replicate their DNA independently of the nuclear DNA of the cell in which they reside. Non-nuclear inheritance describes the inheritance of genes from structures other than the nucleus.

Gregor Mendel's pioneering work on the principles of inheritance fundamentally transformed our understanding of how traits are transmitted from generation to generation. His experiments with pea plants laid the groundwork for the discovery of genes, discrete units within organisms that control heredity.
Each gene exists in pairs, and the combination of these genes from both parents forms an individual's genotype. This genotype is a blueprint of potential traits. Examples of genotype...

Resistivity01:22

Resistivity

4.5K
When a voltage is applied to a conductor, an electrical field is generated, and charges in the conductor feel the force due to the electrical field. The current density that results depends on the electrical field and the properties of the material. In some materials, including metals at a given temperature, the current density is approximately proportional to the electrical field. In these cases, the current density can be modeled as:

Summary

Pearl millet downy mildew resistance is inherited via a single dominant gene, Rsg1. This simple genetic control from resistant parent DMRP 292 facilitates breeding efforts against Sclerospora graminicola.

Area of Science:

  • Plant breeding
  • Genetics
  • Agronomy

Background:

  • Downy mildew (Sclerospora graminicola) poses a significant threat to pearl millet (Pennisetum glaucum) production.
  • Understanding the genetic basis of resistance is crucial for developing resistant cultivars.

Purpose of the Study:

  • To investigate the inheritance pattern of downy mildew resistance in pearl millet.
  • To identify the genetic control of resistance in the DMRP 292 germplasm.

Main Methods:

  • A cross was made between a resistant (DMRP 292) and susceptible (DMSP 23) pearl millet line.
  • Segregating generations (F1, F2, BC) were evaluated for downy mildew reaction after artificial inoculation.
  • Homozygosity for resistance/susceptibility was achieved through three generations of single plant selection.

Main Results:

  • Complete resistance to downy mildew in DMRP 292 is controlled by a single dominant gene.
  • The gene conferring resistance was designated as Rsg1.
  • The simple inheritance pattern simplifies the utilization of this resistance in breeding programs.

Conclusions:

  • Downy mildew resistance in pearl millet, specifically from DMRP 292, is governed by a single dominant gene (Rsg1).
  • This finding provides a straightforward approach for incorporating downy mildew resistance into pearl millet breeding lines.
  • The identified gene offers a valuable tool for developing improved pearl millet varieties with enhanced disease resistance.
