Plant Breeding and Biotechnology

22.3K
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

9.2K
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...

Microbes in the Production of Fermented Foods

192
Lactic acid bacteria (LAB) and molds are instrumental in fermenting plant-based foods to enhance preservation and ensure year-round availability. These microbial processes convert plant carbohydrates into organic acids and other metabolites that inhibit spoilage organisms and contribute to the sensory qualities of the final product.In sauerkraut production, cabbage goes through a microbial succession that starts with cocci such as Leuconostoc mesenteroides. These microbes begin fermentation by...

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:

  • Agricultural science
  • Plant breeding
  • Nutritional science

Background:

  • Vegetables are significant sources of phenolic acids, which are powerful antioxidants with health benefits.
  • Increasing phenolic acid content in vegetables is a crucial objective for crop improvement and human health.

Purpose of the Study:

  • To explore strategies for enhancing phenolic acid content in vegetables.
  • To identify genetic resources and methods for breeding vegetables with improved antioxidant properties.

Main Methods:

  • Screening germplasm collections for natural variation in phenolic acid content.
  • Utilizing modern genomics tools like QTL detection and candidate gene approaches.
  • Evaluating gene action and heritability for selection efficiency.

Main Results:

  • Significant diversity in phenolic acid content exists among vegetable cultivars and wild relatives.
  • High heritability estimates suggest efficient selection for increased phenolic acid content.
  • Genomic and biotechnological strategies are effective for identifying key genes and genomic regions.

Conclusions:

  • Conventional and modern breeding strategies can be combined to develop new vegetable varieties with enhanced phenolic acid levels.
  • Careful consideration of potential trade-offs with other important crop traits is necessary during genetic enhancement.
