trans-Zeatin is widely used in plant tissue culture to promote cell division and shoot formation. It stimulates the growth of buds and helps in breaking seed dormancy, making it valuable in micropropagation of plants. It is also applied to enhance plant regeneration and improve the success rate of cloning elite plant varieties. In agriculture, trans-zeatin is used to delay senescence, helping leaves stay green longer and maintaining photosynthetic activity. This can lead to improved crop yields and better stress tolerance in plants. Additionally, it plays a role in biotechnology for developing transgenic crops with enhanced growth characteristics.
