Tubular structures in developing plastids of three dicotyledonous species
Tubular structures were observed in the developing plastids of the meristematic regions of spinach, beet, and turnip leaves. These structures were located near the plastid periphery, were frequently in contact with the plastid envelope and (or) the ...

Sugars as Central Integrators of Plant Immunity and Stress Responses
ABSTRACT Sugars are fundamental metabolites that sustain plant growth and development, but accumulating evidence demonstrates that they also function as regulatory hubs in plant defence. In this review, we synthesise current knowledge on how carbohydrate dynamics coordinate metabolism, signalling, and structural responses to shape plant resistance ...

Hidden Strategies Beneath a Single Nucleotide: Contrasting Physiology in Lichen Photobiont Strains
ABSTRACT Lichen photobionts exhibit significant physiological variability with important ecological implications. While this variability is relatively well studied at the interspecific level, it has rarely been examined at the intraspecific level. Here, we investigated the physiological responses to temperature and irradiance of two Trebouxia lynniae ...

ABSTRACT Polyamines are key regulators of plant stress responses, yet their contribution to coordinating local immune responses with systemic immunity remains poorly understood. Here, we investigated how spermine (Spm) homeostasis influences local and systemic defence responses in Arabidopsis thaliana following inoculation with Pseudomonas syringae pv.

ABSTRACT Cytokinins (CKs), classically recognised as plant growth regulators, are increasingly implicated in plant‐microbe interactions. Studies in herbaceous plants suggest that CKs can function as signalling molecules with dual roles in plant defence, either restricting or facilitating pathogen infection.

ABSTRACT In nature, plants are subjected to multiple environmental stress factors simultaneously or sequentially. Recent studies revealed that when three or more stress factors impact a plant simultaneously (termed ‘multifactorial stress combination’; MFSC), plant survival declines, even if the intensity of each individual stress involved in the MFSC ...

ABSTRACT Plants are simultaneously exposed to multiple abiotic stresses, yet how opposing epigenetic signals are integrated remains unclear. Here, we investigated the combined effects of heat stress and phosphate deficiency in Arabidopsis thaliana, two conditions with antagonistic impacts on DNA methylation.

Iron homeostasis in the annual and perennial stem zones of Arabis alpina
Iron accumulates in secondary growth tissues in the perennial stem zone and is correlated with particular gene expression patterns in the perennial model plant Arabis alpina. Abstract Plants store nutrients, including the micronutrient iron, in bioavailable forms to support growth in subsequent seasons. The perennial lifestyle is preponderant in nature.

Overlap between Fe and Zn responsive gene regulatory networks (GRNs) were found, indicative of micronutrient crosstalk, and conservation of root and leaf GRNs and genes suggests strong constraint on homeostasis networks in plants. Abstract Micronutrient stress impacts growth, biomass production, and grain yield in crops.
