Agricultural Biotechnology

Agricultural biotechnology employs scientific techniques to improve plants, animals, and microorganisms by enhancing our understanding of DNA. This enables breeders to identify genes and confer advantages to certain crops, making improvements in agricultural productivity that are not possible through traditional crossing or working with related species alone. Biotechnology enhances breeders’ ability to precisely craft solutions for the betterment of crops and livestock.

How is Agricultural Biotechnology Used?

There are different methods thats are used in agricultural biotechnology which are discussed below;

Genetic engineering: 

Genetic modification (GM), often known as genetic engineering (GE), is a way for scientists to transfer genes from one living thing to another. They do this to make improvements in the genes, like adding resistance to diseases, in plants, animals, or tiny organisms. GM crops, also called GMOs, have been made to help farmers grow more food and protect their crops from things like weeds, diseases, and bugs. Even though some people argue about genetic modification. It’s really important for making crops better by moving specific DNA traits around.

Molecular markers:

Traditional breeding is a way that scientists choose specific plants or animals based on how they look and certain traits that can be measured. Instead of just looking at the appearance, scientists also examine the DNA of the organism. They use molecular markers to find and select the ones that have genes we want or don’t have genes we don’t want. This makes breeding more accurate and faster.

At the International Institute of Tropical Agriculture, scientists are using molecular markers to create crops like cowpea that can resist the bruchid beetle, white yam that is resistant to diseases, and cassava that can resist Cassava Mosaic Disease. With molecular markers, scientists can also find and get rid of genes that are not good, making sure the crops are healthier for the future.

Molecular diagnostics:

In farming and animal husbandry, scientists use advanced methods called molecular diagnostics to find and diagnose diseases in crops and livestock. These methods help them accurately figure out if certain genes and their products, like proteins, are present. This precision ensures that the results are specific and reliable, making it easier to identify and deal with diseases in agriculture.


In the Philippines, science is making a big difference in keeping animals and people healthy. A special kind of technology called biotechnology is helping us fight against diseases that can affect both livestock (like cows and water buffaloes) and humans. Scientists have created new vaccines that are better and safer than the old ones. These vaccines are especially helpful for small farmers in hot countries because they are not only cheaper but also don’t need to be kept in a fridge.

One of these improved vaccines protects animals from a disease called hemorrhagic septicemia, which used to be a big cause of death for cattle and water buffalo. Now, with this new vaccine that doesn’t need to be kept cold, more animals can be protected, keeping them safe and healthy.

Tissue culture:

In biotechnology, tissue culture plays a crucial role in creating healthy plants for different crops. This process happens in a carefully controlled lab setting, where specific plant parts are reproduced efficiently. For example, it helps produce disease-resistant versions of fruits like citrus, pineapples, avocados, mangoes, bananas, coffee, and papaya. Essentially, tissue culture ensures we can grow plants without diseases, providing better quality crops. 

Applications of Biotechnology:

Biotechnology and Agriculture:

Biotechnology has really changed the way we grow crops by using genetic modification. This means scientists can tweak the genes of plants to make them better in various ways.
