Physiological dominance of the scion in shaping root architecture under suboptimal temperature

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Non‐optimal temperatures have become a major constraint on plant development under rapidly changing climatic conditions. Both suboptimal and supra‐optimal temperatures reduce physiological activity, alter plant morphology, lead to plant mortality, and ultimately decrease crop productivity.

Photosynthetic activity and protective reactions of mosses in forest ecosystems of the Ukrainian Roztochia under changing ecological conditions

Біологічні студії
Background. The photosynthetic activity of mosses has not been studied sufficiently, in contrast to vascular plants. Taking into account the specifics of the moss gametophyte organization (poikilohydricity, absence of epidermis, stomata, cuticle), it is ...

Regulation of Rubisco by inhibitors in the light

, 1997
2-carboxy-D-arabinitol-1-phosphate (CA1P) bound to Rubisco either in leaf extracts or after purification can be displaced by SO42- ions. Thus, treatment of leaf extracts with a buffer containing 200 mol m-3 SO42- displaces any bound CA1P and enables ...

Gene turnover in the common ancestor of all C4 grasses

PLANTS, PEOPLE, PLANET, EarlyView.
Understanding how plants evolve more efficient photosynthesis is important in a warming world where improving crop productivity and resilience is a global priority. By generating the first reference genomes for an early‐diverging group of grasses called the Aristidoideae, we were able to reconstruct the genetic makeup of the last common ancestor of all

Structure and functional genes associated with carbon, nitrogen, phosphorus, and sulfur cycling processes in periphyton: A comparison between natural and artificial rivers

River, EarlyView.
Network analysis of functional genes among prokaryotes, and eukaryotes in natural and artificial rivers. Abstract Periphyton in aquatic ecosystems plays vital roles in the elemental cycle process and is vulnerable to anthropogenic interference. However, few studies have explored the elemental cycles of carbon (C), nitrogen (N), phosphorus (P), and ...

DNA‐Enzyme Hybrid Nanostructures: Functional Materials to Modulate Enzymatic Activity

Small, EarlyView.
DNA–enzyme hybrid nanostructures enable precise spatial and stoichiometric control over enzyme organization, offering a powerful platform to modulate catalytic activity. This review critically evaluates key mechanistic hypotheses, including proximity effects, microenvironment changes, confinement, and stabilization, as well as highlighting ...

Characteristics of gas exchange and chlorophyll fluorescence in red and green leaves of Begonia semperflorens

Biologia Plantarum, 2011
To determine the effects of leaf colour on gas exchange and chlorophyll fluorescence, two genotypes of Begonia semperflorens with green leaves or red leaves were compared.

Leaf C:P ratio as a universal indicator of photosynthesis in subtropical woody species: Stoichiometric thresholds and metabolic trade‐offs

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The stoichiometric ratios of carbon (C), nitrogen (N) and phosphorus (P) serve as important indicators for assessing nutrient balance in forest ecosystems, but their relationships with photosynthetic dynamics require deeper characterization.

Molecular and physiological analysis of flag leaf senescence and remobilization of assimilates in bread wheat under terminal drought stress [PDF]

مجله بیوتکنولوژی کشاورزی, 2017
In the physiological study of stem remobilization of assimilates during grain filling, mutant genetic materials are a valuable tool. Two advanced mutant lines of bread wheat (T-67-60 and T-65-7-1) along with their wild type (Tabasi Cv.) were planted at ...
