Biodiversity is threatened by humankind’s continuing usurpation of our planet’s physical space and resources, and the associated damage to the landscape and atmosphere. Food production is widely acknowledged to be the most important human activity that needs to be addressed in order to mitigate the current biodiversity and environmental crises. In this contribution we feature obscure plants cal...

Background and purpose: The textile dyes are considered as important pollutants due to the toxicity on human and environment. Therefore, the dye removal from industrial effluents is necessary. This study evaluates the ability of Azolla for the adsorption of acid black 1 (AB1) dye from aqueous solution. Materials and Methods: This was an experimental-laboratory study. The Azolla biomass was sun ...

Nutrients can determine the outcome of the competition between different floating plant species. The response of floating plants to current phosphorus levels may be affected by previously experienced phosphorus concentrations because some species have the ability to store excess phosphorus for later use. This might have an impact on their competition. Here, we investigate the effect of previous...

The phytohormones cytokinin and auxin orchestrate the root meristem development in angiosperms by determining embryonic bipolarity. Ferns, having the most basal euphyllophyte root, form neither bipolar embryos nor permanent embryonic primary roots but rather an adventitious root system. This raises the questions of how auxin and cytokinin govern fern root system architecture and whether this ca...

Environmental sustainability is an integral aspect of living a better life, which will continue to be globally highlighted in the future. Sustainable Development Goals (SDGs) are crucial most research areas improve natural resources that ensure long-term viability environment. The rising population may lead increased pollution due extensive anthropogenic activities. Natural being increasingly e...

Objective: The present study was designed for isolation of bioactive polyphenolic compounds from methanol extract of Azolla microphylla and their subsequent characterization. Methods: The flavonoid compounds were isolated and characterized by using thin layer chromatography (TLC), purified by preparative thin layer chromatography (PTLC) and were identified using High performance chromatography ...

The widely distributed water fern Azolla was investigated for use as an amendment in the bioremediation of fuel-contaminated environments. In a field experiment Azolla pinnata as well as Pistia stratiotes and Salvinia molesta were applied to plots containing soil that had been surface-contaminated with diesel fuel (2.4 L m(-2)) and flooded with water. The plants quickly died and bacterial flocs...

Treatment with ethylene accelerated the abscission of branches of Azolla filiculoides plants. An Azolla plantlet treated with ethylene at 10 microl liter(-1) divided into 4-5 fragments after a lag period of 6-8 h. Ethylene-induced abscission was effectively inhibited by cycloheximide and was associated with an increase in the activities of cellulase and polygalacturonase. At the fracture surfac...

Background and purpose: The 2-chlorophenol (2-CP) and 4-chlorophenol (4-CP) are phenolic compounds which may have adverse effects on human and environment. Therefore, removing these compounds from water and wastewater is necessary. This study aims to analyze 2-CP and 4-CP removal by using Azolla filiculoides biomass. Materials & Methods: Azolla biomass was sun dried, crushed and sieved to parti...
