Biopesticides and Biofertilizers: Development of environmentally friendly pesticides and fertilizers derived from plants or microorganisms.
Transgenic Crops: Study of genetically modified crops, such as Bt cotton or Golden Rice, and their impact on food security and agriculture.
f. Plant Pathology
Plant pathology focuses on plant diseases caused by pathogens such as fungi, bacteria, viruses, and nematodes, as well as how plants defend themselves from these threats.
Key Topics:
Plant Diseases: Study of common diseases affecting crops, trees, and ornamental plants.
Disease Resistance: Understanding how plants resist or tolerate infections through immune responses and structural defenses.
Plant-Pathogen Interactions: Exploring the molecular and cellular mechanisms through which pathogens infect plants and how plants recognize and fight these invaders.
g. Plant Conservation
Plant conservation focuses on the protection and preservation of plant species, especially those that are endangered or threatened.
Key Topics:
Biodiversity Conservation: Study of how to protect plant biodiversity at local, national, and global levels.
Habitat Restoration: Techniques used to restore plant habitats that have been degraded or destroyed by human activities.
Endangered Plant Species: Understanding the causes of plant endangerment and developing strategies to conserve rare species.
