Abstract

Some cacti accumulate large amounts of biominerals such as calcium oxalate (CaC₂O₄) in their stems, but their physiological functions are poorly understood.
In this study, we investigated the characteristics of biominerals and their accumulation in N. cochenillifera. We first separated and extracted biominerals from cladodes of this cactus and observed using a scanning electron microscope.
Elemental analysis of the isolated biominerals was performed using energy dispersive X-ray spectroscopy (EDS). The spectrum obtained by EDS matched that of calcium oxalate (CaC₂O₄). Therefore, it was clarified that most of the biominerals contained in N. cochenillifera are calcium oxalate.
Next, we measured the diameter and density of calcium crystals in epidermis tissues from cladodes of different sizes (4-5, 9-10, and 16 cm or more in length) in order to investigate changes in calcium oxalate crystals during plant growth.
Then, the diameter of calcium oxalate crystals increased significantly as the cladodes grew.
These results indicate that crystals are synthesized within the epidermal tissue as the cladodes grew.
Lastly, we measured the amount of calcium oxalate crystals contained in the cladode and epidermal tissue.
Then, it was revealed that the whole cladode contains about 45 mg g^‑1 DW, and epidermal tissue contains about 170 mg g^‑1 DW of calcium oxalate.
The functions of calcium oxalate crystals have been reported in some desert plants, which include reflecting sunlight, avoiding damage by insects, and acting as a source of CO₂ during droughts.
Calcium oxalate crystals in N. cochenillifera might also function similarly.
Since some cacti (including N. cochenillifera) can grow to more than 5 m in height and several hundred kg in weight, these species can be a long-term carbon fixation source that can be used even in arid regions because of its fast growth rate and large biomass.
