Transgenic Plants

7.4K
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...

Plant Breeding and Biotechnology

19.6K
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.

In-vitro Mutagenesis

14.1K
To learn more about the function of a gene, researchers can observe what happens when the gene is inactivated or “knocked out,” by creating genetically engineered knockout animals. Knockout mice have been particularly useful as models for human diseases such as cancer, Parkinson’s disease, and diabetes.

Reporter Genes

11.7K
Reporter genes are a type of protein-coding gene that are often tagged to a gene of interest. Once inside a target cell, reporter genes usually produce visually identifiable characteristics like fluorescence and luminescence when expressed along with the gene of interest. Thus, reporter genes “report” the presence or absence of genes of interest in an organism, determine the gene expression pattern, or track the physical location of a DNA segment or protein in the cell.

Background:

  • Orphan genes are unique genetic elements without detectable sequence similarity to other genes.
  • They are found across all species and play roles in stress responses and species-specific evolution.
  • Limited research and annotation hinder the understanding of orphan gene functions.

Approach:

  • This review synthesizes current knowledge on orphan gene origins and evolution.
  • It examines methods for screening and characterizing orphan genes in plants.
  • The study analyzes challenges and proposes future research directions for orphan gene functional studies.

Key Points:

  • Orphan genes are widespread and contribute to unique biological processes.
  • Functional characterization of orphan genes is challenging due to lack of annotation.
  • Investigating orphan genes is crucial for a comprehensive understanding of genome evolution and function.

Conclusions:
