Namely, the absorption of metals by roots is diminished when facing highest levels of metals in the environment; alternatively, plants seem to enhance the translocation to diminish the concentration of toxic metals in roots. łh bl mb vol mgt f8 UC BP jb. Cortex thickness of roots was negatively correlated with metals accumulated in roots. Aerenchyma can form in primary tissues (primary aerenchyma) and in secondary tissues (secondary aerenchyma). aerenchyma synonyms, aerenchyma pronunciation, aerenchyma translation, English dictionary definition of aerenchyma. Highest bioconcentration factors (BCFs) were observed in plants growing in less polluted areas. When corn cultivars were grown in sand, aerenchyma was found in both the flooded and controlled (well‐drained) treatments but the ratio of aerenchyma formation to root cortex was significantly greater under flooded conditions than those grown in well‐drained soils (Lenochova et al., 2009). Aerenchyma formation is therefore important for the adaptation of plants in environments with excess water, such as plants with roots in waterlogged soils or submerged shoots.

Aerenchyma is of great importance in crop survival in waterlogging. Lysigenous aerenchyma is found in rice, wheat (Triticum aestivum), barley (Hordeum vulgare), and corn. Under several abiotic stresses, including P deficiency, upland cereal crops, such as maize, are well known to develop lysigenous aerenchyma, a root tissue containing gas spaces. Contrary to upland species, rice develops aerenchyma constitutively. It is characteristically found in aquatic floating plants. Both types provide enlarged spaces for gas-phase diffusion.

Here, we summarize the characteristics of primary aerenchyma (schizogenous and lysigenous aerenchymas) and secondary aerenchyma types, and present recent advances in understanding the mechanisms of lysigenous aerenchyma formation.
