Root aerenchyma – formation and function
Acta Agriculturae Slovenica, 2006 The formation of root aerenchyma, the prominent air spaces in the root cortex which are normally induced by waterlogging, has an important role in providing an internal pathway for oxygen transport between roots and the aerial environment.

Newly identified miRNAs may contribute to aerenchyma formation in sugarcane roots
Plant Direct, 2020 Small RNAs comprise three families of noncoding regulatory RNAs that control gene expression by blocking mRNA translation or leading to mRNA cleavage. Such post‐transcriptional negative regulation is relevant for both plant development and environmental ...

Longitudinal Pattern of Aerenchyma Formation Using the Ti-Gompertz Model in Rice Adventitious Roots
Frontiers in Plant Science, 2021 The longitudinal pattern of root aerenchyma formation of its relationship with the function of adventitious roots in rice remains unclear. In this study, the percentage of the aerenchyma area to the cross-sectional area (i.e., aerenchyma percentage) was ...

Mechanisms of aerenchyma formation in maize roots [PDF]
African Journal of Agricultural Research, 2019 Respiration is very sensitive to waterlogged conditions. Under these conditions, plant roots suffer from lack of available oxygen. In fact, waterlogging reduces the exchange of gases between the plant and the atmosphere. When plants cannot receive sufficient oxygen level for respiration, they form aerenchyma in their roots which function as reservoirs ...

Aerenchyma tissue of Juncus effusus L.: a novel resource for sustainable natural cellulose foams
Cellulose, 2023 AbstractThe demand for sustainable, low-cost, and high-performance natural cellulose foams with isotropic structures has increased greatly due to growing environmental awareness. However, the synthesis of current cellulose foams/aerogels requires substantial amounts of energy and chemicals, mainly due to the challenges posed by the poor solubility and ...

Contrasting development of lysigenous aerenchyma in two rice genotypes under phosphorus deficiency
BMC Research Notes, 2018 Objectives Phosphorus (P) deficiency is a major limitation to plant growth. 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 ...

Transcription factor bHLH121 regulates root cortical aerenchyma formation in maize
Proceedings of the National Academy of Sciences, 2023 Root anatomical phenotypes present a promising yet underexploited avenue to deliver major improvements in yield and climate resilience of crops by improving water and nutrient uptake. For instance, the formation of root cortical aerenchyma (RCA) significantly increases soil exploration and resource capture by reducing the metabolic costs of root tissue.
