Efficient delivery of nanoparticles (NPs) to plants is important for agricultural application. However, to date, we still lack knowledge about how NPs' charge matters for its translocation pathway, i.e., symplastic and apoplastic pathways, in plants. In this study, we synthesized and used ...
Scale bars in (E), 1 cm; in (F)–(K), 50 μm; dashed boxes; postphloem unloading domain. See also Figure S1. It is largely unknown how proteins and miRNA signals move between cells. In principle two routes are possible in plants. The first is through the process of exo- and end...
The same pathway options exist for the movement of nitrogenous metabolites from infected cells to the nodule xylem. Mean plasmodesmatal frequency was estimated from 1 nodule of each of 4 20-day soybean plants. All cell combinations were connected via the symplasm. Plasmodesmatal frequency was ...
The C4 dicarboxylic acid pathway of photosynthetic carbon metabolism is a major elaboration of the photosynthetic carbon reduction cycle (PCR-cycle) which has stimulated a great deal of new research into all levels of carbon metabolism in higher plants in recent years (Hatch and Slack, 1970; ...
Sorbitol and sucrose are the two main soluble carbohydrates in mature peach leaves. Both are translocated in the phloem, in peach as in other rosaceous trees. The respective role of these two soluble carbohydrates in the leaf carbon budget, and their phloem loading pathway, remain poorly ...
Additionally, variation in the methods used to determine the frequencies compounds the problem further. Data presented in this paper show that plasmodesmograms offer a means to visualise the potential transport pathway from mesophyll cells to sieve tubes. Furthermore, the results allow an instant ...
. (2) Plasmodesmata occupy anywhere from 0路08 to 0路002 times the area in common between adjacent cells; a relative area of about 0路01 (found in the mature cortical cells of Allium cepa roots) is not unusual. (3) The plasmodesmata constitute the pathway of least resistance for the ...
