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 کاملBiogenic synthesis of Copper nanoparticles using aquatic pteridophyte Marsilea quadrifolia Linn. rhizome and its antibacterial activity
The spread of contagious diseases and the increase in the drug resistance amongst pathogens has enforced the researchers to synthesize biologically active nanoparticles. Development of eco-friendly practice for the synthesis of nanoparticles is growing bit by bit in the field of nano-biotechnology. The present investigation outlines the development of a method to biosynthesize copper nanopartic...
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 کاملThe fine structure of fertilization in the fern Marsilea vestita.
The ultrastructural details of fertilization in the fern Marsilea vestita, including gamete approach and fusion, the fate of the spermatozoid organelles and the development of a possible block to polyspermy are described. The spermatozoid approaches the egg through layers of mucilage that surround the megaspores. It moves down the neck of the archegonium into the cavity above the egg. In order ...
متن کاملSpermiogenesis in the fern Marsilea microtubules, nuclear shaping, and cytomorphogenesis.
Spermiogenesis in Marsilea is a complex series of events, including the formation of a helically wound organelle coil. The coil begins to appear in early development when a multilayered structure (MLS) is formed de novo in association with a mitochondrion. The outermost layer of the MLS is a ribbon of microtubules. As the microtubules grow out from the MLS, they grow along the nuclear envelope....
