Sugar compartmentation as an environmental stress adaptation strategy in plants
2018, Seminars in Cell and Developmental BiologyCitation Excerpt :Uninfected cells are able to absorb sucrose and glucose while the infected cells are not [61]. Because of the high number of plasmodesmata between infected and uninfected cells [62], the infected cells may depend on uninfected cells for carbon supply via symplastic transport. Given the profile of sugar uptake activity of uninfected cells, legume plants may secrete sucrose and glucose into infected regions.
Increasing Nitrogen Fixation and Seed Development in Soybean Requires Complex Adjustments of Nodule Nitrogen Metabolism and Partitioning Processes
2016, Current BiologyCitation Excerpt :After symplasmic movement into uninfected cells, uric acid is used for allantoin synthesis, and allantoic acid is produced from allantoin [10, 11]. The ureides allantoin and allantoic acid are generally released into the apoplasm and move toward the vasculature located at the nodule periphery (Figures 1A and 1B) [12, 13]. Apoplasmic flow is finally blocked by the Casparian strip of the vascular endodermis and the boundary layer of the inner cortex [14–16].
Visualization of water transport into soybean nodules by Tof-SIMS cryo system
2015, Journal of Plant PhysiologyCitation Excerpt :Therefore, convective water transport of D2O across root tissue is most unlikely to occur. The present results agreed with the experimental results reported by Brown et al. (1995), where endodermis within root nodules restricted solute transport. They examined plasmodesmatal frequency for all cell wall combinations in the nodule, and suggested that there were symplastic and apoplastic restrictions on solute fluxes to and from the nodule in the nodule vascular endodermis.
From North to South: A latitudinal look at legume nodulation processes
2013, South African Journal of BotanyCitation Excerpt :With the exception of Listia where they are lupinoid, nodules on all genera are indeterminate, usually branched and where known (Aspalathus, Lebeckia Thunb., Leobordea Lotononis,) have an epidermal infection with no infection threads and with uniformly infected central tissue (Fig. 1.3A). The latter poses some interesting questions, since the uninfected cells of legumes such as soybean are known to play a vital role in the assimilation and export of products of nitrogen fixation (by symplastic movement) as well as being the route by which carbon compounds such as sucrose are passed to the infected cells (by apoplastic movement: Brown et al., 1995 and references therein). Crotalarioid nodules appear to be very effective in fixing nitrogen (e.g. Ardley et al., 2013) so how do they manage without these uninfected cells?
