Comparing Mitochondrial, Chloroplast, and Prokaryotic Genomes02:16

Comparing Mitochondrial, Chloroplast, and Prokaryotic Genomes

17.3K
The present-day mitochondrial and chloroplast genomes have retained some of the characteristics of their ancestral prokaryotes and also have acquired new attributes during their evolution within eukaryotic cells. Like prokaryotic genomes, mitochondrial and chloroplast genomes neither bind with histone-like proteins nor show complex packaging into chromosome-like structures, as observed in eukaryotes. Unlike mitotic cell divisions observed in eukaryotic cells, mitochondria and chloroplasts...

Overview of Metabolism

40.6K
Living cells constantly carry out various chemical reactions which are necessary for their proper functioning. These reactions are interlinked to one another via multiple pathways. The collection of these chemical reactions is known as metabolism.
Plant Metabolism
Sunlight, the primary source of energy in plants, is first absorbed by the chlorophyll pigments present in their leaves. Plants then use this energy to carry out photosynthesis, where water is oxidized into oxygen and carbon dioxide...

Meristems and Plant Growth

50.3K
Plants grow throughout their lives; this is called indeterminate growth, and it distinguishes plants from most animals. Although certain parts of plants stop growing (e.g., leaves and flowers), others grow continuously—like roots and stems.

Transgenic Plants02:50

Transgenic Plants

8.9K
Recombinant DNA technology called transgenesis is often used to add a foreign gene or remove a detrimental gene from an organism. Such genetically modified organisms are called transgenic organisms.
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...

Epigenetic Regulation01:37

Epigenetic Regulation

4.0K
Epigenetic changes alter the physical structure of the DNA without changing the genetic sequence and often regulate whether genes are turned on or off. This regulation ensures that each cell produces only proteins necessary for its function. For example, proteins that promote bone growth are not produced in muscle cells. Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

Summary
This summary is machine-generated.

Plant methylome evolution is shaped by genomic changes over long timescales and epimutations over short timescales. Analyzing methylation site frequency spectrum (mSFS) in natural populations offers new insights into evolutionary forces.

Area of Science:

  • Plant epigenetics
  • Evolutionary biology
  • Genomics

Background:

  • DNA methylation patterns in plants are crucial for gene regulation.
  • Understanding the evolutionary mechanisms shaping plant methylomes remains a challenge.

Purpose of the Study:

  • To investigate the evolutionary forces driving plant methylome changes over different timescales.
  • To explore the utility of methylation site frequency spectrum (mSFS) analysis for studying methylome evolution.

Main Methods:

  • Analysis of intra- and interspecific epigenomic data from plants.
  • Comparative analysis of methylome evolution over short and long evolutionary timescales.
  • Application of methylation site frequency spectrum (mSFS) analysis to natural populations.

Main Results:

  • Methylome evolution over long timescales is primarily a consequence of genomic alterations.
  • Methylome evolution over short timescales is mainly driven by spontaneous epimutations.
  • mSFS analysis provides a powerful approach to dissect evolutionary forces acting on plant methylomes.

Conclusions:

  • Genomic changes and epimutations are key drivers of plant methylome evolution at different timescales.
  • mSFS analysis offers novel insights into the evolutionary dynamics of plant epigenomes.
