Plant Hormones

Plant Hormones

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.

Plant Breeding and Biotechnology

Plant Breeding and Biotechnology

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.

Plant Tissue Culture

Plant Tissue Culture

Plant tissue culture is widely used in both primary and applied science. Applications range from plant development studies to functional gene studies, crop improvement, commercial micropropagation, virus elimination, and conservation of rare species.

Transgenic Plants

Transgenic Plants

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...

Production of Biopesticides

Production of Biopesticides

Biopesticides offer a sustainable alternative to chemical pesticides, utilizing microbial agents to control agricultural pests. Bacillus thuringiensis (Bt) is a widely employed bacterium known for its potent insecticidal activity. Bt biopesticides are favored for their specificity to insect pests, minimal environmental impact, and natural degradability.Mechanism of Bt Toxin Action Bt produces insecticidal crystal (Cry) proteins during its sporulation phase. These proteins form parasporal...

Summary

Plant sterols and steroid hormones, brassinosteroids (BRs), are vital for plant growth and stress response. Modulating BR pathways offers a promising strategy for enhancing crop yield and improving agriculture.

Area of Science:

Plant Biology
Biochemistry
Agricultural Science

Background:

Plant sterols and brassinosteroids (BRs) are crucial for plant growth, reproduction, and stress tolerance.
BRs regulate numerous physiological processes, making them key targets for crop improvement.

Purpose of the Study:

To review how manipulating sterol and BR metabolism and signaling impacts agronomically important plant traits.
To explore the potential of exogenous steroid application and inhibition in crop enhancement.
To identify future research directions for optimizing BRs in agriculture.

Main Methods:

Literature review focusing on sterol and brassinosteroid biosynthesis and signaling pathways.
Analysis of studies investigating genetic modifications and exogenous applications of steroids.
