Plant Breeding and Biotechnology

19.0K
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.

Cell Signaling in Plants

5.6K
Plant cells communicate to coordinate their cycle of growth, flowering and fruiting, and activities in roots, shoots, and leaves in response to the changing environmental conditions. Plant signaling is distinct from animal signaling. Plants primarily utilize enzyme-linked receptors, whereas the largest class of cell-surface receptors in animals are G-protein coupled receptors (GPCRs). Unlike animals, receptor tyrosine kinases are rare in plants. Instead, plants have a diverse class of...

Transgenic Plants

7.3K
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...

Key Elements for Plant Nutrition

18.8K
Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...

Area of Science:

  • Plant Science
  • Synthetic Biology
  • Biosensor Technology

Background:

  • Plants possess sophisticated mechanisms to perceive and respond to environmental stimuli due to their sessile nature.
  • Genetically encoded plant-based biosensors (GEPBs) are engineered systems that harness these natural plant sensing pathways.
  • GEPBs repurpose plant biological and molecular components for easily detectable outcomes.

Purpose of the Study:

  • To review the framework for engineering various types of GEPBs.
  • To highlight validated biological components for constructing plant biosensors.
  • To discuss the diverse applications of GEPBs in plant science and bioengineering.

Main Methods:

  • Review of existing literature on GEPB development and applications.
  • Summarization of engineering frameworks for GEPB construction.
  • Identification and discussion of biological components and their sources (natural or de novo).

Main Results:

  • GEPBs enable in vivo monitoring of plant biological processes.
  • Applications span basic plant growth studies, environmental monitoring, and stress management.
  • Synthetic biology approaches allow integration of non-plant biological components.

Conclusions:

  • GEPBs are versatile tools for advancing plant science research and applications.
  • The design and identification of biological components are crucial for GEPB development.
  • Future strategies should focus on optimizing component selection and engineering for enhanced GEPB functionality.
