  • Genome-wide identification of polar auxin transporter gene families reveals a possible new polar auxin flow in inverted cuttings of Populus yunnanensis

    In addition, some researchers believe that a new downward flow appears to be established in addition to the original upward polarity (Went, 1941). A number of studies conducted in the 21st century focused on the inducement and function of cell polarity, and a few studies investigated the development of polarity during the growth of inverted cuttings (Souter and Lindsey, 2000; Friml et al., 2006; Hable and Hart, 2010; Medvedev, 2012; Strzyz, 2017; Bornens, 2018). Yunnan white poplar, also called Populus yunnanensis, is an important native dioecious tree that is widely distributed in southwest China (Jiang et al., 2013; Li et al., 2014).

  • Comparative systemic analysis of the cellular growth of leaves and roots in controlled conditions

    The polarity of the root meristemic cells is also expressed by the asymmetrical allocation of the structures related with division, for example, the location of the cell body (nucleus with elements of the cytoskeleton) (Barlow et al., 2004). The unequal cell division division in the root meristem and the symmetric one in the leaf is consistent with an idea about a greater expressed polarity along the apical-basal axis than along the proximodistal axis (which is in a leaf) (Friml et al., 2006). The differences described in the cellular division of the investigated above/underground parts of a plant can be a reflection of the polarity of the entire plant, caused by the need to adapt to the environmental conditions.

  • Cell polarity in plants: When two do the same, it is not the same....

    2011, Current Opinion in Cell Biology
    Citation Excerpt :

    However, after germination the terms become ambiguous because in the anatomical terminology both plant ends, the shoot and root tips are defined as apices and the shoot–root junction (not defined in embryos) as base (Figure 1c). For the sake of simplicity, the embryo-derived terminology was proposed to be used for cell polarity in all developmental contexts [7] or to be replaced by ‘shootward or rootward’ [8]. A consistent terminology for lateral domains is also missing.
