Effects of Ethephon on Aerenchyma Formation in Rice Roots

Rice Science, 2009
Abstract The effects of ethephon on the constitutive aerenchyma formation in roots were studied with a rice variety Yangdao 6 as material. The number of air spaces formed by disintegrated cells in mediopellis increased significantly with the rising ethephon concentrations, whereas superoxide dismutase (SOD) activity showed downward trends.

Root Cortical Aerenchyma Enhances Nitrogen Acquisition from Low-Nitrogen Soils in Maize [PDF]

PLANT PHYSIOLOGY, 2014
Suboptimal nitrogen (N) availability is a primary constraint for crop production in developing nations, while in rich nations, intensive N fertilization carries substantial environmental and economic costs. Therefore, understanding root phenes that enhance N acquisition is of considerable importance.

Rewetting is not enough: Sphagnum transplants promote lowering of greenhouse‐gas emissions in peatlands

Restoration Ecology, Volume 34, Issue 1, January 2026.
Abstract Introduction Degraded peatlands contribute up to 2 gigatons CO2‐equivalent annually (approximately 5% of anthropogenic greenhouse gas emissions). As restoration efforts increase, the effectiveness of combined hydrological and vegetation restoration strategies remains insufficiently understood.

Adaptações morfoanatômicas de Cyperaceae ao ambiente aquático Morphology and anatomic adaptations of Cyperaceae aquatic habits

Planta Daninha, 2011
No ecossistema aquático há uma faixa de umidade gradiente no solo que interfere diretamente na ocupação das espécies à margem da lâmina de água. Essa zonação ecológica reflete os graus de adaptação que as plantas apresentam para tolerar o alagamento ou a

An updated protocol for high throughput plant tissue sectioning [PDF]

, 2017
Quantification of the tissue and cellular structure of plant material is essential for the study of a variety of plant sciences applications. Currently, many methods for sectioning plant material are either low throughput or involve free-hand sectioning ...

Decoding Peanut Root Adaptation to Combined Environmental Stresses: Challenging the Single‐Stress Paradigm

Applied and Environmental Soil Science, Volume 2026, Issue 1, 2026.
Peanut (Arachis hypogaea L.), a major food and oilseed legume, is increasingly cultivated under marginal and stress‐prone environments. The complex reality of agricultural systems often involves simultaneous exposure to multiple abiotic and biotic stressors such as drought, salinity, nutrient imbalances, toxic metal accumulation, and pathogenic attacks,

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

, 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 ...

Impact of Land Use Change and Drought on the Net Emissions of Carbon Dioxide and Methane From Tropical Peatlands in Southeast Asia

AGU Advances, Volume 6, Issue 6, December 2025.
Abstract Peat decomposition is progressing in Southeast Asia due to lowered groundwater levels (GWL) caused by drainage. Additionally, droughts during El Niño events significantly lower the GWL, the main environmental factor that controls greenhouse gas (GHG; carbon dioxide (CO2) and methane) emissions in peatlands.

Development of schizogenous intercellular spaces in plants

Frontiers in Plant Science, 2015
Gas exchange is essential for multicellular organisms. In contrast to the circulatory systems of animals, land plants have tissues with intercellular spaces (ICSs), called aerenchyma, that are critical for efficient gas exchange.

Mitigation Potential of Greenhouse Gas Emissions Through Nitrogen‐Water Management Optimization in Major Asian Rice Regions

Earth's Future, Volume 13, Issue 12, December 2025.
Abstract Rice production represents a major global food source and a significant contributor to greenhouse gas (GHG) emissions. While nitrogen fertilization and water‐saving irrigation are recognized as effective GHG mitigation strategies in rice cultivation, their synergistic effects and underlying mechanisms remain inadequately characterized.
