Characterization and analysis of a Commiphora species germinated from an ancient seed suggests a possible connection to a species mentioned in the Bible.

A seed recovered during archaeological excavations of a cave in the Judean desert was germinated, with radiocarbon analysis indicating an age of 993 CE- 1202 calCE. DNA sequencing and phylogenetic analysis identified the seedling as belonging to the angiosperm genus Commiphora Jacq., sister to three Southern African Commiphora species, but unique from all other species sampled to date.

Elucidation of PGPR-responsive OsNAM2 regulates salt tolerance in Arabidopsis by AFP2 and SUS protein interaction.

This study investigates the molecular mechanisms underlying salt stress responses in plants, focusing on the regulatory roles of OsNAM2, a gene influenced by the plant growth-promoting rhizobacterium Bacillus amyloliquefaciens (SN13). The study examines how SN13-modulated OsNAM2 enhances salt tolerance in Arabidopsis through physiological, biochemical, and molecular analyses. Overexpression of OsNAM2, especially with SN13 inoculation, improves germination, seedling growth, root length, and biomass under high NaCl concentrations compared to wild-type plants, indicating a synergistic effect.

All tangled up: Unraveling phylogenetics and reticulate evolution in the vining ferns, Lygodium (Schizaeales).

Premise: Reticulate evolution, often accompanied by polyploidy, is prevalent in plants, and particularly in the ferns. Resolving the resulting non-bifurcating histories remains a major challenge for plant phylogenetics. Here, we present a phylogenomic investigation into the complex evolutionary history of the vining ferns, Lygodium (Lygodiaceae, Schizaeales).

Trichoderma produces methyl jasmonate-rich metabolites in the presence of Fusarium, showing biostimulant activity and wilt resistance in tomatoes.

Bioactive secondary metabolites from fungi, including Trichoderma, are an excellent source of plant biostimulants. Although production of novel biostimulants from known microbes is critical, challenging them may produce novel bioactive compounds. With this hypothesis, the study used live Fusarium chlamydosporum (FOL7) culture as the inducer during T.

A modified methodology for extraction and quantification of microplastics in soil.

The ubiquitousness of microplastics (<5 mm) has become a pressing environmental concern globally due to the extensive use of plastics. Microplastics have been well-studied in aquatic environments but not well-characterized in soils. Present analytical processes to quantify microplastics accurately in soil samples are quite challenging and require improved and validated analytical steps to eliminate the obscurities and biases.

A kinetic modelling approach to explore mechanism of Cr(VI) detoxification by a novel strain Pseudochrobactrum saccharolyticum NBRI-CRB 13 using response surface methodology.

A novel Pseudochrobactrum saccharolyticum strain NBRI-CRB 13, isolated from tannery sludge, was studied to grow up to 500 mgL of Cr(VI) and showed Cr(VI) detoxification by reducing > 90% of Cr(VI) at different concentrations 25, 50 and 100 mgL. Kinetic studies showed that first-order models were fitted (R = 0.998) to the time-dependent Cr(VI) reduction with degradation rate constant (k) (1.

ELONGATED HYPOCOTYL 5 regulates steroidal glycoalkaloid biosynthesis and fungal tolerance in tomato.

Tomato (Solanum lycopersicum L.) is rich in nutrients and has been an important target for enhancing the accumulation of various metabolites. Tomato also contains cholesterol-derived molecules, steroidal glycoalkaloids (SGAs), which contribute to pathogen defense but are toxic to humans and considered antinutritional compounds.

Essential Oils from Southern Italian Aromatic Plants Synergize with Antibiotics against , and Cell Growth and Biofilm Formation.

The spread of antibiotic-resistant pathogens has prompted the development of novel approaches to identify molecules that synergize with antibiotics to enhance their efficacy. This study aimed to investigate the effects of ten Essential Oils (EOs) on the activity of nine antibiotics in influencing growth and biofilm formation in , , and . The effects of the EOs alone and in combination with antibiotics on both bacterial growth and biofilm formation were analyzed by measuring the MIC values through the broth microdilution method and the crystal violet assay, respectively.

Comprehensive analysis of micro and macro-minerals, phytochemicals and proximate composition of G. forst fruits.

Plants have long served as a valuable source of bioactive components in traditional ayurvedic remedies for disease prevention. In our research, we explored an underutilized plant species, G. Forst.

Jasmonate signaling modulates root growth by suppressing iron accumulation during ammonium stress.

Plants adapt to changing environmental conditions by adjusting their growth physiology. Nitrate (NO3-) and ammonium (NH4+) are the major inorganic nitrogen forms for plant uptake. However, high NH4+ inhibits plant growth, and roots undergo striking changes, such as inhibition of cell expansion and division, leading to reduced root elongation.

Metabolomics and anti-inflammatory activity of Commiphora madagascariensis jacq. leaves extract using in vitro and in vivo models.

C. madagascariensis, an unexplored species of Burseraceae is used by local population for the management of inflammation and throat pain. The disease alleviation by this plant could be due to the presence of rich repository of active compounds with various pharmacological importances.

HY5 and COP1 function antagonistically in the regulation of nicotine biosynthesis in Nicotiana tabacum.

Nicotine constitutes approximately 90% of the total alkaloid content in leaves within the Nicotiana species, rendering it the most prevalent alkaloid. While the majority of genes responsible for nicotine biosynthesis express in root tissue, the influence of light on this process through shoot-to-root mobile ELONGATED HYPOCOTYL 5 (HY5) has been recognized. CONSTITUTIVE PHOTOMORPHOGENIC1 (COP1), a key regulator of light-associated responses, known for its role in modulating HY5 accumulation, remains largely unexplored in its relationship to light-dependent nicotine accumulation.

The underestimated fraction: diversity, challenges and novel insights into unicellular cyanobionts of lichens.

Lichens are remarkable and classic examples of symbiotic organisms that have fascinated scientists for centuries. Yet, it has only been for a couple of decades that significant advances have focused on the diversity of their green algal and/or cyanobacterial photobionts. Cyanolichens, which contain cyanobacteria as their photosynthetic partner, include up to 10% of all known lichens and, as such, studies on their cyanobionts are much rarer compared to their green algal counterparts.

HY5 and PIF antagonistically regulate HMGR expression and sterol biosynthesis in Arabidopsis thaliana.

Secondary metabolites play multiple crucial roles in plants by modulating various regulatory networks. The biosynthesis of these compounds is unique to each species and is intricately controlled by a range of developmental and environmental factors. While light's role in certain secondary metabolites is evident, its impact on sterol biosynthesis remains unclear.
