Plant Breeding and Biotechnology

20.1K
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.

Transgenic Plants

7.6K
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...

Area of Science:

  • Plant biology
  • Space science
  • Genetics

Background:

  • Space exploration necessitates understanding plant responses to microgravity and cosmic radiation.
  • Research aims to develop superior crop varieties for extraterrestrial environments.
  • Previous studies show space conditions induce genetic and phenotypic diversity in plants.

Purpose of the Study:

  • To review molecular mechanisms and genetic mutations in plants grown in space.
  • To explore the application of these findings in future space breeding programs.

Main Methods:

  • Review of existing literature on space-grown plants.
  • Analysis of genetic and molecular changes induced by space environment factors.
  • Examination of crop varieties developed through space research.

Main Results:

  • Cosmic radiation and microgravity cause DNA damage and chromosomal aberrations.
  • These changes lead to genetic polymorphism and novel crop genotypes/phenotypes.
  • Space-grown plants exhibit diverse genetic and biochemical modifications.

Conclusions:

  • Genetic mutations in space-grown plants offer potential for developing resilient crops.
  • Understanding these mechanisms is crucial for advancing space agriculture and breeding.
  • Future space breeding programs can leverage these induced genetic variations.
