摘要: In plants, actin filaments have an important role in organelle movement and cytoplasmic streaming. Otherwise microtubules a restricting organelles to specific areas of the cell maintaining morphology. somatic plant cells, also participate division morphogenesis, allowing cells take their definitive shape order perform functions. latter case, influence assembly wall, controlling delivery enzymes involved cellulose synthesis wall modulation material proper sites. angiosperm pollen tubes, is generally attributed acto-myosin system, main which distributing cytoplasm carrying secretory vesicles apex for polarized growth. Recent data on membrane trafficking suggests fine repositioning sustain tube This review examines secretion endocytosis, highlighting new research cues regarding construction tube-pistil crosstalk, that help unravel
