Figure 2. Plant growth conditions impact the dnf2 phenotype.

Figure 2

Nodules were harvested 18 days post inoculation with Rm41. a-i, Wild-type nodules. j-r, dnf2–4 nodules. Left panels, middle panels and right panels represent nodules grown on agar-, agarose- and agarose-based BNM supplemented with 1% ulvan respectively. Panels a, b, c, j, k and l (scale bars 500 µm) illustrate whole nodules, panels d, e, f, m, n and o (scale bars 200 µm except for d 500 µm) are thin sections of whole nodules and panels g, h, i, p, q, r (scale bars 50 µm) are enlargement of the zone III of panels d, e, f, m, n and o, respectively.
