FIGURE 1

Nodule-like structures (NLSs) appear to be structurally similar in rice and Medicago roots. Images of (A) rice (Nipponbare cv.), and (B) Medicago truncatula (A17) NLS 14 dpt with 50 μM 2,4-D under controlled conditions. Images in (A,B) were taken at 12.5X magnification using a Leica MZ6 stereomicroscope. Images of rice (Nipponbare cv.) NLS at (C) 7 dpt and (D) 14 dpt captured by SEM. (F,G) Represent SEM images of Medicago (A17) NLS at 7 and 14 dpt, respectively. (E,H) Represent images of emerging lateral roots in rice and Medicago, respectively. SEM images were taken at 1400X magnification. Bars equal 80 μm. (I,J) Represent longitudinal ultra-thin sections of NLS and lateral root in rice. (K,L) Represent longitudinal ultra-thin sections of NLS and lateral root in Medicago. The sections are 5–8 μm in thickness.
