Table 1 Silicon distribution among organs and their cell walls in wild-type and mutant plant harvested at the ripening stage

From: The impact of silicon on cell wall composition and enzymatic saccharification of Brachypodium distachyon

Organ Plant Total Si (mg plant−1) Si (% of total Si plant−1) Total Si in cell walls (mg plant−1) Si (% of total Si in CW plant−1) Ratio of Si in CW to total Si (%)
Leaves WT 40.5 63 2.7 48 6
Bdlsi1-1 2.7 51 1.5 58 56
Stems WT 3.6 6 0.7 13 20
Bdlsi1-1 0.7 13 < 0.01a < 1  
Spikelets WT 20.0 31 2.1 39 11
Bdlsi1-1 1.9 36 1.1 42 57
Entire shoot WT 64.1 100 5.5 100 9
Bdlsi1-1 5.3 100 2.6 100 49
  1. Data show the average Si content in different organs of wild-type and mutant plants and the proportion of this Si present in non-phytolith form in cell wall material. The standard deviation of the mean values (n = 3) used in the calculations did not exceed 30%
  2. aSamples in which Si was below the detection limit (0.01 mg g−1 CW)
