Leifsonia stereocauli sp. nov., Isolated from Stereocaulon tomentosum Fr. Lichen.

A Gram-stain-positive, aerobic, yellow-pigmented, catalase-positive, oxidase-positive, non-motile with no flagella and irregularly rod-shaped, denominated strain YIM 134122, was isolated from a Stereocaulon tomentosum Fr. lichen gathered on Baima Snow Mountain in Diqing Tibetan Autonomous Prefecture, Yunnan Province, China. The novel strain grew at pH 6.

Plant Coumarin Metabolism-Microbe Interactions: An Effective Strategy for Reducing Imidacloprid Residues and Enhancing the Nutritional Quality of Pepper.

Imidacloprid (IMI) stress positively correlates with the potential of coumarins to alleviate abiotic stress. However, little is known about the pathways and mechanisms by which coumarin reduces the IMI residue by regulating plant secondary metabolism and plant-microbe interactions. This study examined the impact of coumarin on the uptake, translocation, and metabolism of IMI in pepper plants by modulating the signal molecule levels and microbial communities in the rhizosphere and phyllosphere.

Quantitative evaluation of the efficacy and safety of first-line systemic therapies for advanced hepatocellular carcinoma.

Objectives: This study aimed to quantitatively evaluate the efficacy and safety of first-line systemic therapies for treating advanced hepatocellular carcinoma (aHCC).

Methods: The study included clinical trials of first-line systemic therapies for aHCC since the approval of sorafenib in 2007. Hazard function models were used to describe changes in overall survival (OS) and progression-free survival (PFS) over time.

Plant Growth-Promoting Rhizobacteria HL14-3 Inoculation Enhances Drought Tolerance in Cucumber by Triggering Abscisic Acid-Mediated Stomatal Closure.

Drought limits crop growth and yield. Inoculation with plant growth-promoting rhizobacteria (PGPR) emerges as a promising strategy to protect crops against drought. However, the number of drought-tolerant PGPR is limited, and the regulation mechanisms remain elusive.
