Exposure of Arabidopsis thaliana Mutants to Genotoxic Stress Provides New Insights for the Involvement of TDP1α and TDP1β genes in DNA-Damage Response.

Genotoxic stress activates the DNA-damage response (DDR) signalling cascades responsible for maintaining genome integrity. Downstream DNA repair pathways include the tyrosyl-DNA phosphodiesterase 1 (TDP1) enzyme that hydrolyses the phosphodiester bond between the tyrosine of topoisomerase I (TopI) and 3'-phosphate of DNA. The plant TDP1 subfamily contains the canonical TDP1α gene and the TDP1β gene whose functions are not fully elucidated.

Seed quality as a proxy of climate-ready orphan legumes: the need for a multidisciplinary and multi-actor vision.

In developing countries, orphan legumes stand at the forefront in the struggle against climate change. Their high nutrient value is crucial in malnutrition and chronic diseases prevention. However, as the 'orphan' definition suggests, their seed systems are still underestimated and seed production is scanty.

MicroRNAs potentially targeting DDR-related genes are differentially expressed upon exposure to γ-rays during seed germination in wheat.

DNA damage response (DDR), a complex network of cellular pathways that cooperate to sense and repair DNA lesions, is regulated by several mechanisms, including microRNAs. As small, single-stranded RNA molecules, miRNAs post-transcriptionally regulate their target genes by mRNA cleavage or translation inhibition. Knowledge regarding miRNAs influence on DDR-associated genes is still scanty in plants.

Plant-Based Biostimulants for Seeds in the Context of Circular Economy and Sustainability.

Plant-based biostimulants (PBs), agents rich in bioactive compounds, are emerging as key players able to sustainably improve plant growth and crop productivity to address food security. PBs are generally applied as foliar spray or soil irrigation, while more recently, the application as seed priming treatments is being envisaged as a highly sustainable method to also improve seed quality and germination. Therefore, this review proposes to explore the use of PBs for the seeds industry, specifically discussing about the relevance of product market values, sustainable methods for their production, why and how PBs are used for seed priming, and pinpointing specific strengths and challenges.

Genotype-specific germination behavior induced by sustainable priming techniques in response to water deprivation stress in rice.

Changes in seed proteome along the rehydration-dehydration cycle highlight new players in the genotoxic stress response.

Introduction: Several molecular aspects underlying the seed response to priming and the resulting vigor profile are still poorly understood. Mechanisms involved in genome maintenance deserve attention since the balance between stimulation of germination and DNA damage accumulation versus active repair is a key determinant for designing successful seed priming protocols.

Methods: Changes in the Medicago truncatula seed proteome were investigated in this study, using discovery mass spectrometry and label-free quantification, along the rehydration-dehydration cycle of a standard vigorization treatment (hydropriming plus dry-back), and during post-priming imbibition.

Integrative Transcriptomics Data Mining to Explore the Functions of and Genes in the Model Plant.

The tyrosyl-DNA phosphodiesterase 1 (TDP1) enzyme hydrolyzes the phosphodiester bond between a tyrosine residue and the 3'-phosphate of DNA in the DNA-topoisomerase I (TopI) complex, being involved in different DNA repair pathways. A small gene subfamily is present in plants, where has been linked to genome stability maintenance, while has unknown functions. This work aimed to comparatively investigate the function of the genes by taking advantage of the rich transcriptomics databases available for the model plant.

Noninvasive Methods to Detect Reactive Oxygen Species as a Proxy of Seed Quality.

ROS homeostasis is crucial to maintain radical levels in a dynamic equilibrium within physiological ranges. Therefore, ROS quantification in seeds with different germination performance may represent a useful tool to predict the efficiency of common methods to enhance seed vigor, such as priming treatments, which are still largely empirical. In the present study, ROS levels were investigated in an experimental system composed of hydroprimed and heat-shocked seeds, thus comparing materials with improved or damaged germination potential.

Molecular dynamics of seed priming at the crossroads between basic and applied research.

The potential of seed priming is still not fully exploited. Our limited knowledge of the molecular dynamics of seed pre-germinative metabolism is the main hindrance to more effective new-generation techniques. Climate change and other recent global crises are disrupting food security.

Physiological and molecular aspects of seed longevity: exploring intra-species variation in eight Pisum sativum L. accessions.

Conservation of plant genetic diversity is fundamental for crop improvement, increasing agricultural production and sustainability, especially in the face of climatic changes.

Identification and Characterization of SOG1 (Suppressor of Gamma Response 1) Homologues in Plants Using Data Mining Resources and Gene Expression Profiling.

SOG1 (Suppressor of the Gamma response 1) is the master-regulator of plant DNA damage response (DDR), a highly coordinated network of DNA damage sensors, transducers, mediators, and effectors, with highly coordinated activities. SOG1 transcription factor belongs to the NAC/NAM protein family, containing the well-conserved NAC domain and five serine-glutamine (SQ) motifs, preferential targets for phosphorylation by ATM and ATR. So far, the information gathered for the SOG1 function comes from studies on the model plant .

Changes in genotoxic stress response, ribogenesis and PAP (3'-phosphoadenosine 5'-phosphate) levels are associated with loss of desiccation tolerance in overprimed Medicago truncatula seeds.

Re-establishment of desiccation tolerance is essential for the survival of germinated seeds facing water deficit in the soil. The molecular and ultrastructural features of desiccation tolerance maintenance and loss within the nuclear compartment are not fully resolved. In the present study, the impact of desiccation-induced genotoxic stress on nucleolar ultrastructure and ribogenesis was explored along the rehydration-dehydration cycle applied in standard seed vigorization protocols.

A rare case of intrathoracic fetus in fetu ∕ mature teratoma - pathological and imagistic aspects.

Fetus in fetu (FIF) is a rare entity, with a difficult preoperative diagnosis, frequently being an intraoperative surprise. In recent literature, theories pertaining to its development either assimilate the tumor with a monochorionic twin that halted its evolution, or with a highly differentiated mature teratoma. We present the case of a 27-year-old patient, with a cystic tumor in the anterior mediastinum, which intraoperatively proved to be a rare case of intrathoracic FIF.
