Figure 2: Estimation of silicon content in flax.

Si content in flax was compared with Si accumulation in other reported plant species such as rice (4%) and Brachypodium (3.6%) and are classified as high Si accumulators and possess NIP2 while crops like tomato, potato (0.2–0.5%) and flax (0.24%) are classified as poor accumulators and are devoid of NIP2s.
