Conceptual diagram of soil carbon cycling across climatic and environmental gradients in Nordic marshes and grazing effect. Denmark's warmer climate, high nutrient inputs, elevated salinity, and sandy soils promote rapid microbial decomposition of predominantly labile and root‐derived OC, driving high CO2 emissions and relatively high although unstable

Improved waterlogging tolerance of barley (Hordeum vulgare) by pretreatment with ethephon
Root growth into hypoxic or anoxic waterlogged soil relies on internal aeration in plants. The plant hormone ethylene helps adapt to waterlogging by inducing the formation of aerenchyma, which provides a low-resistance pathway for the transport of oxygen

Incidents of flooding in tropical and subtropical fruit trees have increased as a result of climate change. Because of flooding, the anaerobic conditions of the rhizosphere increase the conditions for phytotoxicity and infection by pathogenic fungi and ...

OsMT2b Regulates Pollen Development and ROS Homeostasis in a Photoperiod‐Dependent Manner
ABSTRACT Reactive oxygen species (ROS) are signalling molecules that promote programmed cell death in animal and plant systems. However, their role in rice (Oryza sativa L.) anther development is unclear. In this study, we show that lower transcript levels of the metallothionein gene OsMT2b in japonica rice plants obtained by RNA interference (RNAi ...

Morphological adaptation of roots is critical for plants to survive under waterlogging. In this study, we evaluated the capacity of wheat to form aerenchyma in seminal roots in combination with the growth angle of the roots.

How Plants May Maintain Protein Homeostasis Under Rising Atmospheric CO2
ABSTRACT Vascular plants may employ several physiological mechanisms to stabilize their protein contents as atmospheric CO2 concentrations change over a day, year, decade, or century. One mechanism is that plants may rely more on soil ammonium as their nitrogen source when CO2 increases.

Conceptual representation of topographic gradients in Amazonian igapó forests. High, medium, and low igapós differ in elevation and flood duration, with low igapós experiencing the longest periods of inundation. Fungal mycelia and DNA symbols indicate sampling of root‐associated mycorrhizal communities across the gradient, used to assess the influence ...

ABSTRACT Emissions from trees are an important component of the global methane (CH4) cycle, but their spatial origins (soil vs. in‐stem), transport pathways and environmental influences are not well constrained. To address these issues, this field study characterized spatial and temporal variability in stem emissions of biologically inert radon (222Rn),

Secondary Aerenchyma Formation in Hypocotyl in Summer Leguminous Crops.
The secondary aerenchyma formation in hypocotyl just below the soil surface was investigated by using the young seedings of wild soybean and six summer leguminous crops grown under upland and excessive moisture conditions for 14 days. Under the upland conditions, secondary aerenchyma was scarcely observed in any species.
