What is the main purpose of protoplast fusion in plant biology?

• A. To increase mutation rates in plant varieties
• B. To create new plant varieties
• C. To eliminate pathogenic bacteria in plants
• D. To determine the optimal growth conditions

Answer: (B)

Protoplast fusion is a technique in plant biology used primarily for the creation of new plant varieties. This process involves the fusion of protoplasts, which are plant cells with their cell walls removed, to combine genetic material from different species or varieties. When protoplasts are fused, the resulting hybrid cells can potentially exhibit traits from both parent plants. This method allows for genetic recombination that may not occur naturally through sexual reproduction. It can lead to the development of plants that possess desirable characteristics, such as increased disease resistance, improved yield, or enhanced nutritional value. Over the years, protoplast fusion has been a valuable tool in the field of plant biotechnology, enabling the development of hybrids that would not be possible through traditional breeding methods. The other options address important concepts in plant biology but do not accurately focus on the primary objective of protoplast fusion, which is the generation of new plant varieties through the combination of different genetic materials.
