Photosynthate Partitioning in Soybean Leaves at Two Irradiance Levels [PDF]

Plant Physiology, 1979
High irradiance-acclimated soybean leaves had the same CO(2) exchange rates, but lower starch accumulation rates and correspondingly higher translocation rates than unacclimated leaves. Increased translocation rates were associated with increased sucrose phosphate synthetase (EC 2.4.1.14) activity.

Simulation of carbon cycling, including dissolved organic carbon transport, in forest soil locally enriched with 14C [PDF]

, 2011
The DyDOC model was used to simulate the soil carbon cycle of a deciduous forest at the Oak Ridge Reservation (Tennessee, USA). The model application relied on extensive data from the Enriched Background Isotope Study (EBIS), which exploited a short ...

Genetic and environmental regulation of arbuscular mycorrhizal responsiveness in petunia: Implications for breeding and trait selection

Plant Biology, EarlyView.
Arbuscular mycorrhiza responsiveness varies strongly among Petunia species and RILs, representing a genetically determined trait with breeding potential that is nonetheless strongly modulated by environmental conditions. Abstract Arbuscular mycorrhizal (AM) fungi enhance plant nutrition and stress tolerance, yet their agricultural use remains limited ...

Morpho-physiological analysis of adaptive responses of common bean (Phaseolus vulgaris L.) to drought stress. Thesis (Ph.D.) [PDF]

, 2016
Common bean (Phaseolus vulgaris L.) is the most important food legume in the diet of poor people in the tropics. This legume is cultivated by small farmers and is usually exposed to unfavorable conditions with minimum use of inputs.

Role of magnesium in carbon partitioning and alleviating photooxidative damage [PDF]

, 2008
Magnesium (Mg) deficiency exerts a major influence on the partitioning of drymatter and carbohydrates between shoots and roots. One of the very early reactions of plants to Mg deficiency stress is themarked increase in the shootto- root dry weight ...

Constitutive and inducible oleoresin defenses share genetic architectures and mechanisms in Pinus taeda

New Phytologist, Volume 250, Issue 5, Page 2966-2987, June 2026.
Summary The oleoresin defense system of loblolly pine (Pinus taeda) protects trees from insects and pathogens and is an important source of renewable biofuels and chemicals, but the genetic basis of oleoresin production is poorly understood. We characterized the genetic architecture of oleoresin flow, resin canal number, stem wood terpene content, and ...

Guard cell photorespiration controls stomata behavior and development

New Phytologist, Volume 250, Issue 5, Page 3182-3196, June 2026.
Summary Photorespiration is traditionally viewed as a limitation to photosynthetic efficiency. However, it is mandatory for safeguarding the Calvin–Benson–Bassham cycle from inhibitory byproducts through Rubisco‐mediated oxidative misfire and is tightly integrated with primary metabolism.

Arbuscular Mycorrhiza Modulates Iron Distribution and Vacuolar Iron Transporter Expression in Tomato, Whereas Iron Limitation Reduces Mycorrhization

Plant, Cell &Environment, Volume 49, Issue 6, Page 3290-3305, June 2026.
ABSTRACT Plants have evolved highly efficient strategies to maintain iron (Fe) homeostasis. In this study, we investigate the impact of arbuscular mycorrhizal (AM) symbiosis on the Fe‐deficiency response and ionomic profile of tomato plants, as well as how Fe availability affects AM symbiosis.

Capturing Spatiotemporal and Subgrid Variability in Global Land Surface Albedo Parameterization

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 5, May 2026.
Abstract Accurate surface albedo parameterization is critical for modeling Earth's energy balance. Yet, many schemes rely on static look‐up tables or semi‐empirical formulations that fail to capture spatiotemporal variations and complex radiative interactions. This study develops a physics‐informed machine‐learning parameterization using 19 years (2003–
