Systemic infection with Escherichia coli significantly decreased feed intake, slowed growth of the whole body and skeletal muscles, and severely inhibited muscle protein accumulation in both chicks and rats. Treatment with naproxen (6-methoxy-alpha-methyl-2-naphthaleneacetic acid), an inhibitor of prostaglandin production, decreased weight losses of body and muscle, and significantly inhibited ...

This first-attempt study used microtome-based methods to generate a thin cell layer culture for the micropropagation of Phal. Hwafeng Redjewel × New Cinderella. Protocorms were embedded in various agarose concentrations (8–12%, w/v) and dried from 1 8 h before sectioning with microtome. Optimal conditions slicing sections 100 300 μm achieved when protocorms at 10% (w/v) 4 under laminar flow, ha...

Organogenesis and somatic embryogenesis have been widely applied as the two main regeneration pathways in plant tissue cultures. However, recalcitrance is still restriction clonal propagation of many woody species, especially conifers. They undergo a “phase change” that leads to significant loss vegetative capacity, reducing aptitude tissues organs be regenerated vitro beyond this point. In lin...

Abstract In eggplant microspore embryogenesis, embryos are produced and then transformed into undifferentiated calli, instead of developing as true embryos. This is the main current bottleneck that precludes this process from being efficient. work we aimed to shed light on factors involved in successful vitro development haploid by evaluating role growth regulators (GRs) process. We analyzed en...

The effect of auxin application on auxin metabolism was investigated in excised hypocotyl cultures of carrot (Daucus carota). Concentrations of both free and conjugated indole-3-acetic acid (IAA), [2H4]IAA, 2,4-dichlorophenoxyacetic acid, and naphthaleneacetic acid (NAA) were measured by mass spectroscopy using stable-isotope-labeled internal standards. [13C1]NAA was synthesized for this purpos...

p-Chlorophenoxyisobutyric acid (PCIB) is known as a putative antiauxin and is widely used to inhibit auxin action, although the mechanism of PCIB-mediated inhibition of auxin action is not characterized very well at the molecular level. In the present work, we showed that PCIB inhibited BA::beta-glucuronidase (GUS) expression induced by indole-3-acetic acid (IAA), 2,4-dichlorophenoxyacetic acid...

This study aimed to determine the effects of different concentrations and combinations of the phytohormones 2,4-dichlorophenoxy acetic acid (2,4-D), kinetin, 6-benzylaminopurine (BAP), and 1-naphthaleneacetic acid (NAA) on callus induction and to demonstrate the role of elicitors and exogenous precursors on the production of mitragynine in a Mitragyna speciosa suspension culture. The best callu...

Background and Aims Climate change has resulted in earlier berry development compressed harvests creating problems with harvesting winery logistics causing undesired modifications to grape wine composition, such as elevated concentration of sugar alcohol. Auxin treatment grapevine bunches prior veraison can counteract these adverse changes by delaying maturation. The most efficacious timing 1-n...
