The role of shoot photosynthesis as a means of supporting aerobic respiration in the roots of the seagrass Zostera marina was examined. O(2) was transported rapidly (10-15 minutes) from the shoots to the root-rhizome tissues upon shoot illumination. The highest rates of transport were in shoots possessing the greatest biomass and leaf area. The rates of O(2) transport do not support a simple ga...

This study, first, points the rhizomatic nature of open source software (OSS) communities. Then, it proposes an hypergraph based research methodology both to capture and to analyze dynamics of OSS communities. An exemplary hypergraph theoretical analysis of power antecedence within rhizomatic network of an OSS community is illustrated. I. RHIZOMATIC STRUCTURE The concept of Rhizome is first pre...

Horsetail (Equisetum hyemale) is a widespread vascular plant species, whose reproduction is mainly dependent on the growth and development of the rhizomes. Due to its key evolutionary position, the identification of factors that could be involved in the existence of the rhizomatous trait may contribute to a better understanding of the role of this underground organ for the successful propagatio...

The purpose of this study was to examine the effects of extracts and flavone derivatives from the rhizome of Kaempferia parviflora on P-glycoprotein (P-gp)-mediated transport in LLC-GA5-COL150, a transfectant cell line of a porcine kidney epithelial cell line LLC-PK1 with human MDR1 cDNA. Ethanol extract obtained from Kaempferia parviflora rhizome significantly increased the accumulation of rho...

BACKGROUND Exposure to ultraviolet (UV) radiation causes various forms of acute and chronic skin damage, including immunosuppression, inflammation, premature aging and photodamage. Furthermore, it induces the generation of reactive oxygen species, produces proinflammatory cytokines and melanocyte-stimulating hormone (MSH) and increases tyrosinase activity. The aim of this study was to evaluate ...

There is a growing interest for the plant-based medicines in pharmaceutical industry. Plant derived Antioxidants have gained huge importance regarding their medicinal value. The present study was designed to establish pharmaceutical value of Polygonum amplexicaule for their antioxidant activity using shoot, leaf and rhizome crude methanolic extract along with their n-butanolic, ethanolic, ethyl...

turmeric is an important herb used as medicines, turmeric is an important herb used as medicine, condiment and cosmetic. its main active compounds are curcuminoids and essential oils. the biomass production, essential oil composition and curcuminoid content of curcuma longa are known to be dependent on the growth and development conditions of rhizome. iran is a major importer of turmeric in the...

Chitosan was evaluated for its potential to induce antifungal hydrolases in susceptible turmeric plant (Curcuma longa L.). Under field conditions, the application of chitosan (crab shell) to turmeric plants by foliar spray method induces defense enzymes such as chitinases and chitosanases. Such an increase in enzyme activity was enhanced by spraying chitosan (0.1% w/v) on leaves of turmeric pla...
