Mitochondria affect photosynthesis through altered tissue levels of O₂ Open
Oxygen (O₂) availability in plant tissues is dynamically shaped by photosynthesis and respiration and is linked to plant stress responses and development. While mitochondria are the primary consumers of cellular O₂, their impact on chlorop…

Single-cell transcriptomics reveal how root tissues adapt to soil stress Open
Land plants thrive in soils showing vastly different properties and environmental stresses 1 . Root systems can adapt to contrasting soil conditions and stresses, yet how their responses are programmed at the individual cell scale remains …

Root Growth and Development in “Real Life”: Advances and Challenges in Studying Root–Environment Interactions Open
Plant roots play myriad roles that include foraging for resources in complex soil environments. Within this highly dynamic soil environment roots must sense, interact with, and acclimate to factors such as water availability, microbiota, a…

Soil compaction sensing mechanisms and root responses Open
Soil compaction is an agricultural challenge with profound influence on the physical, chemical, and biological properties of the soil. It causes drastic changes by increasing mechanical impedance, reducing water infiltration, gaseous excha…

<i>Leaf Gas Film 1</i> promotes glycerol ester accumulation and formation of a tight root barrier to radial O2 loss in rice Open
Rice (Oryza sativa L.) and many other wetland plants form an apoplastic barrier in the outer parts of the roots to restrict radial O2 loss to the rhizosphere during soil flooding. This barrier facilitates longitudinal internal O2 diffusion…

Mitochondria affect photosynthesis through altered tissue levels of oxygen Open
Interactions between plant energy organelles, the chloroplasts and the mitochondria, are crucial for plant development and acclimation. These interactions occur at different levels including exchange of metabolites and reducing power, orga…

Net <span>O<sub>2</sub></span> exchange rates under dark and light conditions across different stem compartments Open
Summary Woody plants display some photosynthetic activity in stems, but the biological role of stem photosynthesis and the specific contributions of bark and wood to carbon uptake and oxygen evolution remain poorly understood. We aimed to …

The OsEIL1–OsWOX11 transcription factor module controls rice crown root development in response to soil compaction Open
Optimizing the root architecture of crops is an effective strategy for improving crop yields. Soil compaction is a serious global problem that limits crop productivity by restricting root growth, but the underlying molecular mechanisms are…

Outer apoplastic barriers in roots: prospects for abiotic stress tolerance Open
Floods and droughts are becoming more frequent as a result of climate change and it is imperative to find ways to enhance the resilience of staple crops to abiotic stresses. This is crucial to sustain food production during unfavourable co…

The barrier to radial oxygen loss protects roots against hydrogen sulphide intrusion and its toxic effect Open
Summary The root barrier to radial O 2 loss (ROL) is a key root trait preventing O 2 loss from roots to anoxic soils, thereby enabling root growth into anoxic, flooded soils. We hypothesized that the ROL barrier can also prevent intrusion …

Responses of key root traits in the genus<i>Oryza</i>to soil flooding mimicked by stagnant, deoxygenated nutrient solution Open
Excess water can induce flooding stress resulting in yield loss, even in wetland crops such as rice (Oryza). However, traits from species of wild Oryza have already been used to improve tolerance to abiotic stress in cultivated rice. This …

A quantitative trait locus conferring flood tolerance to deepwater rice regulates the formation of two distinct types of aquatic adventitious roots Open
Summary A key trait conferring flood tolerance is the ability to grow adventitious roots as a response to submergence. The genetic traits of deepwater rice determining the development and characteristics of aquatic adventitious roots (AAR)…

The Pyramiding of Three Key Root Traits Aid Breeding of Flood-Tolerant Rice Open
Flooding is constantly threatening the growth and yield of crops worldwide. When flooding kicks in, the soil becomes water-saturated and, therefore, the roots are the first organs to be exposed to excess water. Soon after flooding, the soi…

Novel functions of the root barrier to radial oxygen loss – radial diffusion resistance to H<sub>2</sub> and water vapour Open
Summary The root barrier to radial O 2 loss (ROL) is a trait enabling waterlogging tolerance of plants. The ROL barrier restricts O 2 diffusion to the anoxic soil so that O 2 is retained inside root tissues. We hypothesised that the ROL ba…
