ANTIBACTERIAL ACTIVITY OF MARSILEA QUADRIFOLIA Linn
Four Leaf Clover'or aalaik keerai in Tamil is in use for more than 3000 years as part of food. It is a pteridophytic plant that is marketed and used by tribals of Eastern India as a nerve relaxant and curative agent due to its nutritional value. In the present study M. quadrifolia leaf extracts have showed effective inhibition against gram negative bacteria such as Salmonella typhi, Pseudomonas...
متن کاملUptake of rare earth elements by Dryopteris erythrosora (autumn fern)
Mechanisms of uptake of rare earth elements (REEs) were investigated, particularly those by REE accumulator species (autumn fern). Rare earth elements are practically insoluble under natural conditions, suggesting some unknown mechanism in REE accumulator species. In the present investigation, two notable phenomena were observed. (I) Concerning the ionic-radius dependence of REE uptake by leave...
متن کاملAbscisic acid regulation of heterophylly in Marsilea quadrifolia L.: effects of R-(-) and S-(+) isomers.
The plant hormone abscisic acid (ABA) induces a developmental switch in the aquatic fern Marsilea quadrifolia, causing the formation of aerial type characteristics, including the elongation of petioles and roots, a change in leaf morphology, the expansion of leaf surface area, and the shortening of the internodes. A number of ABA-responsive heterophylly (ABRH) genes are induced early during the...
متن کاملAntimicrobial activities of Turbinaria conoides (J. Agardh) Kutzing and Marsilea quadrifolia Linn
Turbinaria conoides (J. Agardh) Kutzing ,(Phaeophyceae) a marine seaweed, and Marsilea quadrifolia Linn. (Marsileaceae) an aquatic fern, were tested for activity against Tobacco necrotic virus (TNV) and bacteria (antimicrobial). Local lesion method was adopted and half leaf comparisons were made in cotyledonary leaves of Cyamopsis tetragonoloba Taub.(Linn.). Extracts of the experimental plants ...
متن کاملResponses to shading of naturalized and non-naturalized exotic woody species.
BACKGROUND AND AIMS Recent studies have suggested that responses to shading gradients may play an important role in establishment success of exotic plants, but hitherto few studies have tested this. Therefore, a common-garden experiment was conducted using multiple Asian woody plant species that were introduced to Europe >100 years ago in order to test whether naturalized and non-naturalized sp...
