“…The actin microfilament network is essential for polar growth and intra-cellular communication: MFs mediate vesicle transport, cytoplasmic streaming, extension growth, anchoring of the nucleus, orientation of the cell division plane, gravity sensing, signalling of pathway integration, defense signalling, etc. (Baluška et al, 2001;Ketelaar et al, 2002;Klyachko, 2004;Bannigan and Baskin, 2005;Blancaflor, Wang, and Motes, 2006;Morita, 2010;Yoo et al, 2012;Blancaflor, 2013;Janda, Matoušková, Burketová, and Valentová, 2014). The actin cytoskeleton could be considered as a finer and more dynamic structure than MTs.…”
