Genetic engineering offers a fast route to improve peanut (Arachis hypogea) yields. This study details an Agrobacterium-mediated transformation protocol for peanuts, achieving over 70% transformation frequency for crop enhancement.

Area of Science:

  • Agricultural Science
  • Plant Biotechnology
  • Genetics

Background:

  • Peanut (Arachis hypogea) is a vital legume crop facing challenges like drought, pests, and diseases, leading to low yields.
  • Current agricultural practices and limited high-yielding cultivars hinder optimal peanut production.
  • Genetic engineering presents a rapid strategy for enhancing crop resilience and productivity.

Purpose of the Study:

  • To describe an efficient Agrobacterium-mediated transformation protocol for peanut (Arachis hypogea).
  • To establish a reliable method for generating genetically transformed peanut plants for crop improvement.
  • To provide a foundation for developing improved peanut cultivars resistant to biotic and abiotic stresses.

Main Methods:

  • Utilized an Agrobacterium-mediated transformation system.
