“…O 2 concentration decreases sharply through the inner cortex, and the O 2 permeability is flexibly controlled by this layer (Witty andMinchin 1990, Hunt andLayzell 1993). It is hypothesized that a reversible exchange of intercellular water by the inner cortical cells plays a role in the regulation of nodule conductance to O 2 diffusion (Serraj et al, 1995, Fleurat-Lessard et al, 2005. There are lenticels outside of nodules and one layer of epidermis.…”

“…These data suggest a role of this AQP in the physiology of symbiosis, although the precise role of Nod26 in ammonia permeation has yet to be demonstrated. PIP and TIP proteins are abundant in both the PM and tonoplast of the inner cortical cells (IC-cells) of Glycine max root nodules (Fleurat-Lessard et al 2005). This distribution is consistent with their putative role of water flux facilitation associated with the regulation of nodule conductance to O 2 diffusion and the subsequent ATP-dependent nitrogenase activity.…”

Aquaporins are a class of intrinsic membrane proteins that are primarily associated with water movement across membranes. In plants, biophysical studies indicated that water fluxes could not be explained by simple diffusive movement. The discovery of aquaporins that facilitate water movement across membranes in other organisms rapidly led to the identification of this class of proteins in plants. The large number of aquaporin genes identified in plant genomes compared to those from other organisms suggests that they play a major role in plant water relations. However, plant aquaporins also facilitate the transport of small solutes such as glycerol, silicon, ammonium, urea, boric acid, CO 2 , arsenite, and hydrogen peroxide within and between cells. Here, the aquaporin-like proteins that function on the plant plasma membrane are reviewed in the context of their apparent role in plant adaptive evolution.

“…In fact, 5 plant aquaporin families have been structurally and functionally well-studied and characterized [26,27]. A recent study showed a significant similarity between the amino acid sequences of soy, spinach, corn, tomato, and tobacco with human aquaporin epitope 207-232 [28].…”

Multiple sclerosis (MS) is an autoimmune disease that affects the body's central nervous system. Around 90% of MS sufferers are diagnosed with relapsing-remitting MS (RRMS). We used ELISA to measure IgG, IgA, and IgM antibodies against linear epitopes of human and plant aquaporins (AQP4) as well as neural antigens in RRMS patients and controls to determine whether patients suffering from RRMS have simultaneous elevations in antibodies against these peptides and antigens. In comparison to controls, significant elevations in isotype-specific antibodies against human and plant AQP4 and neural antigens such as MBP, MOG, and S100B were detected in RRMS patients, indicating a high correlation in antibody reaction between plant aquaporins and brain antigens. This correlation between the reactivities of RRMS patients with various tested antigens was the most significant for the IgM isotype. We conclude that a subclass of patients with RRMS reacts to both plant and human AQP4 peptides. This immune reaction against different plant aquaporins may help in the development of dietary modifications for patients with MS and other neuroimmune disorders.
