Linking Superoxide Production and Scavenging in Plant Development

open access: yesPlant, Cell &Environment, Volume 49, Issue 4, Page 2048-2068, April 2026.
ABSTRACT Due to their strong oxidizing potential, rapid membrane permeability, and high reactivity, reactive oxygen species (ROS) play essential roles in plant development and stress responses. Superoxide (O2•‐) is a primary product of molecular oxygen reduction and a crucial source of hydrogen peroxide, representing a ROS species of substantial ...

RNAseq revealed the important gene pathways controlling adaptive mechanisms under waterlogged stress in maize

open access: yesScientific Reports, 2017
Waterlogging causes yield penalty in maize-growing countries of subtropical regions. Transcriptome analysis of the roots of a tolerant inbred HKI1105 using RNA sequencing revealed 21,364 differentially expressed genes (DEGs) under waterlogged stress ...

Cálcio e o desenvolvimento de aerênquimas e atividade de celulase em plântulas de milho submetidas a hipoxia Calcium and the development of aerenchyma and celulase activity in corn seedlings subjected to hypoxia

open access: yesScientia Agricola, 2001
A formação de aerênquimas é conhecida como uma das mais importantes adaptações anatômicas pelas quais as plantas passam quando são submetidas à deficiência de oxigênio.

Ecological strategy of Phyllostachys heteroclada oliver in the riparian zone based on ecological stoichiometry

open access: yesFrontiers in Plant Science, 2022
The abnormality of seasonal water level fluctuation in the riparian zone causes various ecological and environmental problems, such as vegetation degradation, biodiversity reduction, soil erosion, and landscape transformation, thereby critically ...

A multi-scale comparison of modeled and observed seasonal methane emissions in northern wetlands [PDF]

open access: yes, 2016
Wetlands are the largest global natural methane (CH4/ source, and emissions between 50 and 70° N latitude contribute 10-30% to this source. Predictive capability of land models for northern wetland CH4 emissions is still low due to limited site ...

Characterizing the causes and consequences of calcium oxalate crystal presence in Vitis riparia

open access: yesAmerican Journal of Botany, Volume 113, Issue 3, March 2026.
Abstract Premise Calcium oxalate biomineralization in plants is phylogenetically widespread and morphologically diverse, but the function of these inorganic crystals is an area of active debate. The variety of environmental conditions that produce the crystals, as well as the inconsistent evidence that they provide antiherbivore defense across plant ...

Aerenchyma Formation in the Seminal Roots of Japanese Wheat Cultivars in Relation to Growth under Waterlogged Conditions

open access: yesPlant Production Science, 2012
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.

Frozen Soil Hydrological Processes and Their Effects: A Review and Synthesis

open access: yesReviews of Geophysics, Volume 64, Issue 1, March 2026.
Abstract Frozen soils, including seasonally frozen ground and permafrost, are rapidly changing under a warming climate, with cascading effects on water, energy, and carbon cycles. We synthesize recent advances in the physics, observation, and modeling of frozen‐soil hydrology, emphasizing freeze–thaw dynamics, infiltration regimes and preferential flow,

Impact of waterlogging on fruit crops in the era of climate change, with emphasis on tropical and subtropical species: A review

open access: yesAgronomía Colombiana, 2023
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 ...

Impacts of rice varieties and management on yield-scaled greenhouse gas emissions from rice fields in China: A meta-analysis [PDF]

open access: yes, 2014
Increasing numbers of studies have suggested that a comprehensive assessment of the impacts of cropping practices on greenhouse gas (GHG) emissions per unit yield (yield-scaled), rather than by land area (area-scaled), is needed to inform trade-off ...
