植物的生长发育依赖于各向异性的细胞扩张。细胞壁屈服为细胞扩张提供了驱动力，并且部分地通过细胞周围纤维素微纤丝的定向沉积来调节。我们目前对各向异性细胞扩增的理解结合了50多年研究产生的假设。在这里，我们讨论了纤维素合成领域的研究人员不断发展的观点，并强调了几个尚未解决的问题。最近使用活细胞成像的结果已经说明了皮质微管在纤维素合成中的新作用，使用这些方法的进一步研究有望揭示细胞骨架，细胞内运输和各向异性生长之间令人兴奋的联系。(C)2010年，任科学院院士。由Elsevier Masson SAS出版。All rights reserved.
Plant growth and development depend on anisotropic cell expansion. Cell wall yielding provides the driving force for cell expansion, and is regulated in part by the oriented deposition of cellulose microfibrils around the cell. Our current understanding of anisotropic cell expansion combines hypotheses generated by more than 50 years of research. Here, we discuss the evolving views of researchers in the field of cellulose synthesis, and highlight several unresolved questions. Recent results using live-cell imaging have illustrated novel roles for cortical microtubules in cellulose synthesis, and further research using these approaches promises to reveal exciting links between the cytoskeleton, intracellular trafficking, and anisotropic growth.
