Role of tubulin tyrosination regulating KCH activity mediated pollen tube growth

The growth of pollen tubes relies on the intricate coordination of cytoskeletal elements, such as microtubules and microfilaments. The tyrosination cycle of microtubules regulates cellular polarity by influencing their stability and their interactions with motor proteins. KCH, a key factor linking microtubules to actin, is particularly crucial for pollen tube growth. This study aims to elucidate the mechanisms by which microtubulin tyrosination regulates KCH activity to mediate pollen tube growth.
