Cartwheel aerenchyma in Cardamine amara as a model of schizogenous tissue formation in plants [PDF]

iScience
Summary: Root aerenchyma is essential for survival under waterlogged conditions for plants. It has been necessary to explore a model system of schizogenous aerenchyma in Brassicaceae.

A Role for Auxin in Ethylene-Dependent Inducible Aerenchyma Formation in Rice Roots

Plants, 2020
Internal oxygen diffusion from shoot to root tips is enhanced by the formation of aerenchyma (gas space) in waterlogged soils. Lysigenous aerenchyma is created by programmed cell death and subsequent lysis of the root cortical cells.

A minimal mechanistic model of plant responses to oxygen deficit during waterlogging [PDF]

Quantitative Plant Biology
Plants exhibit diverse morphological, anatomical and physiological responses to hypoxia stress from soil waterlogging, yet coordination between these responses is not fully understood.

The role of OsRGA1 in aerenchyma formation and adventitious root growth in rice seedlings based on the U-Gompertz model [PDF]

BMC Plant Biology
Background Aerenchyma in adventitious roots plays a crucial role in rice growth under flooding conditions. However, the mechanisms underlying the dynamic formation process of aerenchyma remain poorly understood, largely due to the time-consuming and ...

Pectin Peek-a-Boo: Homogalacturonan Turnover During Flooding-Induced Legume Root Aerenchyma Formation [PDF]

Plants
Flooding can cause root hypoxia and can lead to significant agricultural losses. Therefore, understanding plant adaptations to flooding, including root aerenchyma development, is one important avenue for insuring future global food security.

Programmed Cell Death and Aerenchyma Formation in Water-Logged Sunflower Stems and Its Promotion by Ethylene and ROS

Frontiers in Plant Science, 2019
Previous studies have shown that waterlogging/ hypoxic conditions induce aerenchyma formation to facilitate gas exchange. Ethylene (ET) and reactive oxygen species (ROS), as regulatory signals, might also be involved in these adaptive responses. However,

Programmed cell death associated with the formation of schizo-lysigenous aerenchyma in Nelumbo nucifera root

Frontiers in Plant Science, 2022
Nelumbo nucifera (N. nucifera) is an important aquatic economic crop with high edible, medicinal, ornamental, and ecological restoration values. Aerenchyma formation in N.

Primary and secondary aerenchyma oxygen transportation pathways of Syzygium kunstleri (King) Bahadur & R. C. Gaur adventitious roots in hypoxic conditions

Scientific Reports, 2021
Some plant species develop aerenchyma to avoid anaerobic environments. In Syzygium kunstleri (King) Bahadur & R. C. Gaur, both primary and secondary aerenchyma were observed in adventitious roots under hypoxic conditions. We clarified the function of and

Effects of different water conditions on the biomass, root morphology and aerenchyma formation in bermudagrass (Cynodon dactylon (L.) Pers)

BMC Plant Biology, 2022
Background The bermudagrass (Cynodon dactylon (L.) Pers) roots responded differently in terms of morphological and anatomical characteristics under diverse submergence conditions, and they developed aerenchyma under non-flooding condition.

Asymmetric auxin distribution establishes a contrasting pattern of aerenchyma formation in the nodal roots of Zea nicaraguensis during gravistimulation

Frontiers in Plant Science, 2023
Auxin distribution is essential for determining root developmental patterns. The formation of lateral roots and constitutive aerenchyma, which is a gas space developed through cell death, is regulated by auxin in rice (Oryza sativa).
