Sulfonylurea-resistant biotypes of Monochoria vaginalis generate higher ultraweak photon emissions than the susceptible ones

Biotypes of Gardnerella vaginalis.

A simple and reproducible scheme for identifying biotypes of Gardnerella vaginalis has been developed, based on reactions for lipase, hippurate hydrolysis, and beta-galactosidase. Among a total of 359 strains tested, eight biotypes were observed, the most common ones being types 1 (beta-galactosidase positive, lipase positive, hippurate positive), 2 (beta-galactosidase negative, lipase positive...

Pharmacognostical investigation roots of Monochoria vaginalis presl

The present study deals with the macroscpical, microscopical and preliminary phytochemical investigation on Monochoria vaginalis P. The transverse section shows in the root, the presence of cork, cortex, xylem, phloem, pith etc. The diagnostic features of the roots are the presence of fibers associated with vessels, calcium oxalates, and xylem vessel which will help in the identification and au...

Biophoton Emissions in Sulfonylurea-Herbicide-Resistant Weeds

Gibberellin-producing endophytic fungi isolated from Monochoria vaginalis.

The role of endophytic fungi in plant growth and development is well documented. However, endophytic fungi with growth promotion capacity have never been isolated from weeds previously. In the current study, we isolated 8 fungal endophytes from the roots of Monochoria vaginalis, a serious weed of rice paddy in Korea. These isolates were screened on Waito-C, in order to identify plant growth pro...

Structural and Physiological Comparisons of Triazine-Susceptible, -Resistant, and “Mixed” Biotypes of Poa

Triazine-resistant (R) biotypes of several dicot weed biotypes have been shown to differ from triazine-susceptible (S) biotypes both structurally and biochemically. To this point, no R monocot has been examined, however. In this report, we examine the ultrastructure and physiology of three biotypes of Poa annua L.: a S biotype, a R biotype, and a “m ixed” (M) biotype that displays a level of re...
