Plant Breeding and Biotechnology

18.8K
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.

Defenses Against Pathogens and Herbivores

23.1K
Plants present a rich source of nutrients for many organisms, making it a target for herbivores and infectious agents. Plants, though lacking a proper immune system, have developed an array of constitutive and inducible defenses to fend off these attacks.

Cell Signaling in Plants01:25

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 Plants02:50

Transgenic Plants

7.1K
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 Hormones

23.5K
Plant hormones—or phytohormones—are chemical molecules that modulate one or more physiological processes of a plant. In animals, hormones are often produced in specific glands and circulated via the circulatory system. However, plants lack hormone-producing glands.

Area of Science:

  • Plant Science
  • Genetics
  • Microbiology

Background:

  • Plants face constant threats from microbial pathogens and pests due to their immobility and lack of adaptive immunity.
  • These threats significantly reduce global crop yields, necessitating advanced disease control strategies.

Purpose of the Study:

  • To review mechanisms of plant-pathogen interactions and strategies for enhancing plant disease resistance.
  • To identify potential genes for resistance breeding against diverse pathogens and pests.
  • To discuss limitations and future perspectives for durable, broad-spectrum plant immunity.

Main Methods:

  • Comprehensive review of scientific literature on plant immunity, microbial pathogenicity, and genetic engineering.
  • Analysis of molecular and genomic data related to plant-pathogen interactions.
  • Synthesis of information on gene editing, synthetic biology, and resistance breeding techniques.

Main Results:

  • Detailed explanation of the molecular 'tug-of-war' between plants and pathogens.
  • Overview of various strategies for developing disease resistance in plants.
  • Identification of candidate genes for enhancing resistance in key crops against fungi, oomycetes, bacteria, viruses, nematodes, and insects.

Conclusions:

  • Genetic engineering and advanced breeding offer powerful tools to develop disease-resistant crops.
  • Addressing limitations and exploring future perspectives is key to achieving durable, broad-spectrum plant immunity.
  • Continued research is essential to secure global food production against evolving plant diseases.
