Integrative analyses of genetic variation in enzyme activities of primary carbohydrate metabolism reveal distinct modes of regulation in Arabidopsis thaliana

open access: yes, 2008
Background Plant primary carbohydrate metabolism is complex and flexible, and is regulated at many levels. Changes of transcript levels do not always lead to changes in enzyme activities, and these do not always affect metabolite levels and fluxes.

Independent leaf and root responses to autumn freezing in perennial herbs: Insights from cutting and transplant manipulations

open access: yesGrassland Research, EarlyView.
In this study, we compared two sampling approaches to assess autumn freezing resistance. Our goal was to determine whether the commonly employed cutting method, which disrupts root‐tissue connectivity, provides a valid measure of true freezing resistance.

Liebig Review: Essential and Beneficial Elements in the Regulation of Cadmium Uptake and Tolerance in Crop Plants

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Cadmium (Cd2+) contamination in agricultural soils has been reported to pose risks to crop productivity, food safety, and human health. This review synthesizes current knowledge on the mechanisms by which essential (S, Zn, Fe, Mg, K, Ca) and beneficial (Si, Se, rare earth elements) elements mitigate Cd2+ toxicity in plants.

The regulatory frameworks surrounding CRISPR‐edited papaya and their impact on international commerce

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract The papaya tree (Carica papaya L.), native to the Americas, is cultivated in tropical regions and holds substantial economic importance, with an estimated export volume of 365 000 t in 2023. However, diseases caused by viruses, fungi, bacteria, and nematodes can lead to severe losses.

Acclimation responses of Arabidopsis thaliana to sustained phosphite treatments

open access: yes, 2013
Phosphite () induces a range of physiological and developmental responses in plants by disturbing the homeostasis of the macronutrient phosphate. Because of its close structural resemblance to phosphate, phosphite impairs the sensing, membrane transport,

Alpine flora of Kashmir Himalaya: floristic assessment, life history traits and threat status

open access: yesNordic Journal of Botany, EarlyView.
Alpine ecosystems in the Himalaya are considered to be at a higher risk to anthropogenic global change drivers. The Kashmir Himalaya, located in the north‐western side of the Himalayan biodiversity hotspot, harbors a diverse alpine flora, which remains systematically little investigated.

Structural investigation of the Arabidopsis thaliana circadian clock [PDF]

open access: yes
Plants, like most organisms, have developed elaborate mechanisms for anticipating periodic environmental changes. The circadian clock allows an organism to adapt its metabolic, developmental and physiological processes to coincide with favourable ...

The dominance of non‐native plants over native plants increases with the number of global change factors

open access: yesOikos, EarlyView.
Global environmental change and plant invasion are both recognized as key indicators of the Anthropocene. Still, how the number of co‐acting global change factors (GCFs) influence invaded plant communities remains unclear, even though in nature GCFs usually act together rather than alone.

The functional state of cellular antioxidant defence system of shoots of Arabidopsis thaliana exposed to the chronic ionizing radiation in the Chornobyl exclusion zone

open access: yesЯдерна фізика та енергетика, 2016
The functional state of the cellular antioxidant defence system of shoots of Arabidopsis thaliana plants that grow in natural conditions in the areas of the Chornobyl Exclusion Zone with the values of the external dose rate of 0.45, 0.61, 1.05, 4.81 and ...

Arabidopsis thaliana DOF6 negatively affects germination in non-after ripened seeds and interacts with TCP14

open access: yes, 2011
Seed dormancy prevents seeds from germinating under environmental conditions unfavourable for plant growth and development and constitutes an evolutionary advantage.
