Plant Breeding and Biotechnology

21.3K
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

8.3K
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:

  • Agricultural Science
  • Food Science
  • Genetics

Background:

  • Citrus fruits are popular for fresh consumption and juices.
  • Bitterness (naringin, limonin) and sourness negatively impact citrus sensory quality and industry.
  • Improving citrus taste is crucial for consumer appeal and marketability.

Purpose of the Study:

  • To review genes involved in citrus taste pathways (sweet, bitter, sour).
  • To discuss genetic engineering approaches for modifying citrus flavor profiles.
  • To provide insights into citrus breeding for enhanced sensory qualities.

Main Methods:

  • Literature review of genetic and biochemical studies on citrus flavor.
  • Identification and summarization of key genes regulating taste compounds.
  • Discussion of genetic engineering strategies for taste modification.

Main Results:

  • Several major genes have been identified that influence sweet, bitter, and sour taste in citrus.
  • Understanding these genetic pathways is key to manipulating citrus flavor.
  • Genetic engineering offers potential for targeted taste improvement.

Conclusions:

  • Genetic factors significantly shape citrus taste profiles.
  • Targeting specific genes can modify bitterness and sourness.
  • Genetic engineering presents a promising avenue for developing better-tasting citrus varieties.
