Affinity chromatography of Nicotiana tabacum ribonucleases

Phytochemistry, 1974
Abstract The purification of tobacco ribonuclease by affinity chromatography is described. 5′-(4-amino-phenylphosphoryl)-guanosine 2′, (3′) phosphate, a ribonuelease inhibitor, has been synthesized and insolubilized onto agarose beads. The resulting adsorbent binds tobacco and some other plant ribonucleases strongly but reversibly at pH 5.4.

Evaluation of a novel laser‐system operating at 1940 nm for weed control and determining the influence of biological and operational factors

Pest Management Science, Volume 82, Issue 10, Page 10428-10438, October 2026.
The control efficacy of a novel laser pulse system operating at 1940 nm was tested. The new system allows effective control of young weeds with 1.5 J. Targeting the plant stem is 53‐fold more energy‐efficient than the meristem. Species morphology and beam diameter significantly influence weed control efficacy. Abstract BACKGROUND This study evaluates a

Substitution of fiber hemp for corn did not affect soil greenhouse gas emissions from a Kentucky cropping system

Agrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract Industrial hemp's return to American agriculture has been accompanied by claims of the crop's carbon neutrality, primarily due to its commercial applications. While carbon can be sequestered within products made with hemp fiber, there is little empirical evidence quantifying greenhouse gas contributions from the crop's production.

N 6 -methyl-adenosine level in Nicotiana tabacum is associated with tobacco mosaic virus

Virology Journal, 2018
Background N 6 -methyl-adenosine (m6A) is a prevalent RNA modification in many species. Abnormal m6A methylation levels can lead to RNA dysfunction and can cause diseases. Tobacco mosaic virus (TMV) is one of the most devastating viruses for agricultural

Winter biomass potential of four cover crop species: Wheat, rye, triticale, and canola

Agrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract This study examines variability in predicted aboveground biomass (AGB) of winter cover crops (CCs) across Nebraska, focusing on wheat (Triticum aestivum L.), rye (Secale cereale L.), triticale (× Triticosecale), and canola (Brassica napus L.).

Natural Product‐Derived Vesicles in Nanotherapeutics

Journal of Extracellular Vesicles, Volume 15, Issue 9, September 2026.
Natural product‐derived vesicles (NPVs) are an emerging nature‐based nanotherapeutic that can deliver bioactive metabolites into the target site and induce beneficial mechanisms. A practical, chronological bench‐to‐bedside approach throughout the entire NPV development process is expected to resolve challenges encountered in NPV studies.

The insertion of an ancestral gene in Nicotiana tabacum plants reduces free radicals during saline irrigation

Czech Journal of Genetics and Plant Breeding
Transgenic organisms modified with ancestral genes for nitrogen metabolism are rare. Previously, it was reported that genetically modified Nicotiana tabacum with the ARO4 gene of aromatic amino acid synthesis from the yeast Debaryomyces hansenii ...

Focus on DnaJ protein research from Arabidopsis to crop improvement

The Plant Genome, Volume 19, Issue 3, September 2026.
Abstract DnaJ proteins (Hsp40s) are essential components of the cellular proteostasis network, functioning as molecular co‐chaperones that regulate protein folding, stability, and stress‐responsive homeostasis in plants. Beyond their classical role as Hsp70 partners, accumulating evidence demonstrates that DnaJ proteins participate in diverse ...
