Transgenic Plants02:50

Transgenic Plants

9.0K
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...

Meristems and Plant Growth

50.4K
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.

Trihybrid Crosses
Some of Mendel’s crosses examined three pairs of contrasting characteristics. Such a cross is called a trihybrid cross. A trihybrid cross is a combination of three individual monohybrid crosses. For example, plant height (tall vs. short), seed shape (round vs. wrinkled), and seed color (yellow vs. green).
The F1 generation plants of a trihybrid cross are heterozygous for all three traits and produce eight gametes. Upon self-fertilization, these gametes have an equal...

Area of Science:

  • Plant Biology
  • Epigenetics
  • Genomics

Background:

  • DNA methylation is a crucial epigenetic mechanism influencing gene expression in eukaryotes.
  • Understanding epigenetic variation is key to comprehending plant adaptation and evolution.

Purpose of the Study:

  • To investigate the patterns of DNA methylation across a diverse range of flowering plant species (angiosperms).
  • To identify the extent and distribution of DNA methylation and its variability within angiosperms.

Main Methods:

  • Comparative analysis of DNA methylation patterns using genomic sequencing techniques.
  • Bioinformatic analysis to quantify and visualize methylation levels and locations.

Main Results:

  • Substantial variation in DNA methylation levels and patterns was observed among different angiosperm species.
  • Specific regions of the genome showed differential methylation, suggesting functional implications.

Conclusions:

  • The study reveals significant epigenetic diversity in DNA methylation across flowering plants.
  • These findings contribute to our understanding of the role of epigenetics in angiosperm evolution and diversity.
