Low-acyl gellan gum is used in plant tissue culture because it has the ability to gel aqueous solutions and provide a supportive matrix for the growth and development of plant cells and tissues.

In plant tissue culture, the cells are typically grown in a nutrient-rich growth medium that contains essential nutrients, hormones, and other growth factors. Low-acyl gellan gum can be added to the growth medium to form a gel-like matrix that provides a supportive environment for the cells.

The gelling properties of low-acyl gellan gum make it ideal for plant tissue culture because it can form a solid, yet porous, matrix that allows for the exchange of oxygen and nutrients between the cells and the growth medium. This helps to promote healthy cell growth and division.

Additionally, low-acyl gellan gum is biocompatible and does not interfere with the growth or development of the cells, making it a safe and effective tool for plant tissue culture.

Overall, the use of low-acyl gellan gum in plant tissue culture can improve the efficiency and success of plant cell cultures, making it an important tool for plant research and the development of new plant-based products.
