Abstract | Research into plant growth is currently benefiting from the emerging systems-biology doctrine. For the past 20 years, plant-biology research has predominantly focussed on the molecular scale; however, recent interest in the multiscale nature of plant growth has stimulated investigation into plant biomechanical properties and their hormone regulation. Plant and animal cells differ significantly as plant cells: i) cannot generally move relative to one another; ii) contain a tough fibrous cell wall, which resists the high internal turgor pressure whilst allowing significant, often anisotropic, growth; iii) can transport hormones in a polar fashion, which can lead to complex tissue-scale hormone distributions. Thus, although plant-cell biomechanics and hormone dynamics are interesting areas by themselves, it is the interplay between these two areas that is key to understanding plant growth and development – hormone dynamics depend on tissue geometry, whilst tissue growth is regulated by hormone concentration. The first session focuses on cell-scale growth. Within this session, experimental and theoretical speakers have been paired together, with two talks on diffusely growing cells followed by two talks on tip-growing cells. The second session focuses on growth on the tissue scale; the first speaker will discuss experimental and theoretical work on root twisting, and the final three speakers will present multiscale models that couple hormone dynamics to plant development and growth. |
