Improving Flooding Tolerance of Crop Plants

open access: yesAgronomy, 2018
A major problem of climate change is the increasing duration and frequency of heavy rainfall events. This leads to soil flooding that negatively affects plant growth, eventually leading to death of plants if the flooding persists for several days.

Implementation and evaluation of a new methane model within a dynamic global vegetation model: LPJ-WHyMe v1.3.1 [PDF]

open access: yes, 2010
For the first time, a model that simulates methane emissions from northern peatlands is incorporated directly into a dynamic global vegetation model. The model, LPJ-WHyMe (LPJ <B>W</B>etland <B>Hy</B>drology and <B>Me</B ...

Effects of Ethephon on Aerenchyma Formation in Rice Roots

open access: yesRice 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]

open access: yesPLANT 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.

Undervalued Ecosystems: Ponds Boost Regional Macrophyte Diversity

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 2, February 2026.
ABSTRACT Ponds—depressional wetlands with ≤ 2 ha—are largely undervalued worldwide, despite serving as crucial diversity reservoirs. However, the extent to which ponds support diversity at the landscape scale is still underappreciated. Here, we investigate the contributions of ponds to macrophyte beta and gamma diversity in a subtropical wetland ...

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

open access: yesPlanta 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

Phylogeny and historical biogeography of the Pachira sensu lato clade (Bombacoideae, Malvaceae) with a new infrageneric classification

open access: yesTAXON, Volume 75, Issue 1, February 2026.
Abstract We explore phylogenetic relationships within the Pachira sensu lato clade (Bombacoideae, Malvaceae), test the monophyly of the genera Eriotheca and Pachira, and investigate their biogeographic history. The Pachira s.l. clade comprises ca. 72 species that traditionally have been placed in Eriotheca and Pachira. We sampled ca. 79% of its species

Unlocking the Impact of Temperature and Salinity on Greenhouse Gas Emissions From Estuarine Salt Marsh Soils

open access: yesEarth's Future, Volume 14, Issue 2, February 2026.
Abstract Salt marshes hold substantial potential for nature‐based climate solutions; yet their carbon sequestration potential is threatened by greenhouse gas (GHG) emissions under global warming and sea‐level rise (SLR). The combined effects of temperature and salinity on soil GHG emissions still remain unclear. This study integrated in situ monitoring
