Potential components of the barrier to radial oxygen loss (ROL) are suberin and/or lignin, which accumulate at the cell wall in the cells of peripheral cell layers of the root. Chemical composition of the apoplastic barrier in rice roots was characterized and it was suggested that ROL can be restric...

Internal aeration is crucial for root growth in waterlogged soil. A barrier to radial oxygen loss (ROL) can enhance long- distance oxygen transport via the aerenchyma to the root tip; a higher oxygen concentration at the apex enables root growth into anoxic soil. The ROL barrier is formed within the...

Aerenchyma is continuous gas space between shoot and roots that contributes to the internal aeration in plants. In response to excess water stress and the plant hormone ethylene, maize (Zea mays) forms aerenchyma in root cortical cells by programmed cell death (PCD). The aim of this study was to und...

Strigolactones have been defined as a new group of phytohormones that regulate shoot branching. The phenotypes of strigolacton-related rice (Oryza sativa) dwarf (d) mutants demonstrated that SLs inhibit mesocotyl elongation by controlling cell division. Moreover, the trans-zeatin, one of active cyto...
