Mature raphid and raphid idioblast
structure in plants of the edible aroid genera Colocasia, Alocasia and Xanthosoma.
Calcium deposition in idioblasts
of mulberry leaves.
Jubaea chilensis lacks raphide bundles and raphide containing idioblasts
in the staminate petals, as observed in Butia (Martel et al.
Mesophyll (Figure 3E) consists of spongy and palisade parenchyma, and often contains druse idioblasts
In Plant kingdom, oxalate is a common photosynthetic byproduct (2) and many plants are known to synthesize calcium oxalate crystals which are stored in leaves and organ cells like idioblasts
The midrib and secondary veins of damaged and control leaves characteristically feature druses in the parenchyma and idioblasts
with tannins (Figure 4U, V).
with raphids immersed in pectic matrix (Fig.
Diversity and distribution of idioblasts
producing calcium oxalate crystals in Dieffenbachia seguine (Araceae).
The authors conclude that in dry environments, the canopy contains numerous layers of thick cells, whereas in humid environments, the canopy presents fewer layers of cells, and the exodermis shows higher numbers of idioblasts
in plants treated with at least 50% urea (Figure 2B).
2002), also showed druses placed in special idioblasts
or in lumen of chlorenchymatic cells.
Sections of leaves from plants cultivated in the greenhouse showed the layer of palisade cells well-organized and some of these cells underwent periclinal division; well-developed cuticle; presence of idioblasts
containing crystals (Figure 3).
Five shapes of minor vascular bundles are found: arrosetate (78), round in outline (79), elliptical (80), ovoid (81), or mixed round in outline and elliptical (82); idioblasts
with rachids are present or absent (83).
