Herbimycin B, a new benzoquinonoid ansamycin with anti-TMV and herbicidal activities.

The Journal of Antibiotics, 1980
A new benzoquinonoid ansamycin, herbimycin B was isolated from the culture broth of Streptomyces hygroscopicus No. AM-3672, a herbimycin A-producing strain. Herbimycin B showed potent anti-TMV activity. Herbicidal effect of herbimycin B was less than that of herbimycin A.

Anti-TMV activity and functional mechanisms of two sesquiterpenoids isolated from Tithonia diversifolia

Pesticide Biochemistry and Physiology, 2017
Unlike chemical pesticides, antiviral plants are biodegradable, replenishable and safe. In this study, 14 sesquiterpene compounds from Tithonia diversifolia were tested for their activities against Tobacco mosaic virus (TMV) using the half-leaf method.

The IKU2/RLK7–MAPK–MINI3 signaling module controls endosperm cellularization timing to determine seed size in Arabidopsis

Journal of Integrative Plant Biology, EarlyView.
The phosphorylation status of the WRKY transcription factor WRKY10/MINI3, controls the timing of endosperm cellularization in Arabiopsis, thus regulating final seed size, offering a molecular understanding that could inform future agricultural breeding strategies. ABSTRACT Seed size is a critical factor in determining crop yield.

Autoimmunity and Periodontitis

Journal of Periodontal Research, EarlyView.
In a microbe‐driven inflammatory environment, peptidyl‐arginine deiminase (PAD) enzymes from neutrophils and Porphyromonas gingivalis citrullinate both microbial and self‐antigens. B cell presentation of citrullinated or self‐mimicking epitopes activates T cells that assist B cells in antibody isotype switching, affinity maturation, epitope spreading ...

Contradicting Kuhn's Popular Notion of Scientific Revolution: Conservative Revolutionaries in the History of Biology

Natural Sciences, Volume 6, Issue 3, July 2026.
ABSTRACT Proposing the concept of a conservative revolutionary generally and using the examples of Gregor Mendel, Max Delbrück, and Eric Davidson, I fundamentally call into question Thomas Kuhn's ideas of scientific revolutions. I also highlight some problematic consequences of the increasing appreciation of Kuhn's work among scientists and show that ...

Effects of Elevated CO2 on Bean Pod Mottle Virus Infection in Both Incompatible and Compatible Interactions With Phaseolus vulgaris L

Plant, Cell &Environment, Volume 49, Issue 7, Page 4493-4512, July 2026.
ABSTRACT Plant viruses cause significant crop losses, a situation that could worsen due to anthropogenic activities driving global climate change, one factor of which is the increase in atmospheric CO2 concentration. This study assessed the impact of elevated CO2 concentration (eCO2, 1000 vs. 400 ppm) on two genotypes of common bean (Phaseolus vulgaris
