Abstract  As one of the two major cytoskeleton systems, microtubules (MTs) are highly dynamic and undergo rearrangement to respond to the ever-changing developmental cues and environmental stimuli. In particular, plant cells organize specific MT arrays, such as preprophase bands and phragmoplast in mitotic cells and cortical MTs in interphase cells, to fulfill various physiological functions. Here, we highlight the recent research advancements in plant cell MTs, including the core regulatory mechanism of initial assembly and dynamic remodeling of plant cell MTs, how MTs regulate plant cell morphogenesis and how MTs play roles in response to environmental cues. Finally, we also discuss future perspectives about the important questions in this field.
