Enhanced growth and photosynthetic efficiency in wild rocket (Diplotaxis tenuifolia L.) following multi-species microalgal biostimulant application.

Foliar spraying is a simple and efficient technique that enables targeted delivery of biostimulants directly onto plant surfaces, minimizing losses and environmental dispersion. Among biostimulant categories, microalgae-based formulations represent an eco-friendly solution to improve crop productivity, thanks to their richness in bioactive compounds and rapid growth in low-input systems. In this study, the crude extract of three green microalgae with high commercial value and broad biotechnological potential-Auxenochlorella protothecoides, Tetradesmus obliquus and Chlamydomonas reinhardtii-along with their consortium, was tested as foliar biostimulants for the first time on wild rocket (Diplotaxis tenuifolia L.

Leaf senescence-associated genes and transcriptional changes under dark conditions.

Background: Leaf senescence is a high regulated and complex process that can be trigged by dark conditions, as demonstrated in various studies. Dark-induced leaf senescence resembles natural senescence by triggering typical symptoms such as protein degradation and chlorophyll loss. Transcription factors have been recognized as key modulators of dark-induced senescence and are associated with plant hormones such as cytokinins, ethylene, gibberellins, and jasmonic acid.

Recovery of ripening capacity in 'Rocha' pears treated with 1-MCP through the application of 1-NAA: Physiological and molecular analysis insights.

Storing 'Rocha' pear treated with 1-methylcyclopropene (1-MCP) in controlled atmosphere is a common commercial strategy to extend pear storage time and prevent postharvest disorders. However, this strategy represents a challenge to the fruit industry because 1-MCP treatment obstructs the normal fruit ripening, potentially affecting the quality to consumers. To explore possible mechanisms to reactivate ripening, 'Rocha' pears treated with 1-MCP were exposed to 2 and 4 mM 1-naphthaleneacetic acid (1-NAA) and stored at 20 ± 2 °C for 15 days.

Decoding the Intricate Metabolic and Biochemical Changes in Plant Senescence: a focus on chloroplasts and mitochondria.

Background: Plant senescence is a genetically controlled process that results in the programmed death of plant cells, organs, or the entire plant. This process is essential for nutrient recycling and supports the production of plant offspring. Environmental stresses such as drought and heat can hasten senescence, reducing photosynthetic efficiency and significantly affecting crop quality and yield.

Identification of potential molecular markers for detection of lengthy chilled storage of L. fruit.

Low temperature is the main strategy to preserve fruit quality post-harvest, in the supply chain. Low temperatures reduce the respiration, ethylene emission, and enzymatic activities associated with senescence. Unfortunately, peaches are sensitive to low temperatures if exposed for long periods, resulting in physiological disorders that can compromise commercial quality.

In Vitro Investigation of the Anti-Fibrotic Effects of 1-Phenyl-2-Pentanol, Identified from Lam., on Hepatic Stellate Cells.

Liver fibrosis, characterized by excessive extracellular matrix deposition, is driven by activated hepatic stellate cells (HSCs). Due to the limited availability of anti-fibrotic drugs, the research on therapeutic agents continues. Here we have investigated Lam.

Effects of blood sample storage time, temperature, anti-coagulants and blood stabiliser on lymphocyte phenotyping.

Medical diagnostic laboratories have come under further scrutiny to ensure quality standards of their service and external quality assurance (EQA) programs involving multiple laboratories have been used to gauge this quality based on a consensus. However, because of the geographical distances within a country or internationally, cell surface marker expressions may change due to time delays and transport temperatures. Attention was given to this issue some decades ago and hence requires a re-evaluation in consideration of updated methods, reagents and instruments for flow cytometry and phenotyping.

Molecular and physiological responses to salt stress in salinity-sensitive and tolerant Hibiscus rosa-sinensis cultivars.

Ornamental plants are used to decorate urban and peri-urban areas, and during their cultivation or utilisation, they can be exposed to abiotic stress. Salinity is an abiotic stress factor that limits plant growth and reduces the ornamental value of sensitive species. In this study, transcriptomic analysis was conducted to identify genes associated with tolerance or sensitivity to salinity in two hibiscus (Hibiscus rosa-sinensis L.

Identification and expression profile of the SMAX/SMXL family genes in chickpea and lentil provide important players of biotechnological interest involved in plant branching.

SMAX/SMXL family genes were successfully identified and characterized in the chickpea and lentil and gene expression data revealed several genes associated with the modulation of plant branching and powerful targets for use in transgenesis and genome editing. Strigolactones (SL) play essential roles in plant growth, rooting, development, and branching, and are associated with plant resilience to abiotic and biotic stress conditions. Likewise, karrikins (KAR) are "plant smoke-derived molecules" that act in a hormonal signaling pathway similar to SL playing an important role in seed germination and hairy root elongation.

Biochemical and molecular changes in peach fruit exposed to cold stress conditions.

Storage or transportation temperature is very important for preserving the quality of fruit. However, low temperature in sensitive fruit such as peach can induce loss of quality. Fruit exposed to a specific range of temperatures and for a longer period can show chilling injury (CI) symptoms.

Method for selecting ornamental species for different shading intensity in urban green spaces.

In urban areas, ornamental plants face different constraints, such as the shading of buildings and trees. Therefore, the selection of suitable species and their integration or combination with pre-existing plants is very important. Trees, shrubs, and herbaceous plant species must be distributed according to plant light requirements and shading intensity.

Expression profile of the NCED/CCD genes in chickpea and lentil during abiotic stress reveals a positive correlation with increased plant tolerance.

Carotenoid cleavage dioxygenase (CCD) gene family is organized in two subfamilies: (i) 9-cis epoxycarotenoid dioxygenase (NCED) genes and (ii) CCD genes. NCED genes are essential for catalyzing the first step of the abscisic-acid (ABA) biosynthesis, while CCD genes produce precursors of the strigolactones hormone. The functional characterization of these gene subfamilies has not been yet performed in chickpea and lentil.

Biofortification of baby leafy vegetables using nutrient solution containing selenium.

Background: Biofortification of vegetables is an important innovation technique in the horticultural sector. Vegetables can be a vector of different minor elements that have beneficial effects on human health. Selenium (Se) is an important element for human nutrition and plays a significant role in defence mechanisms.
