Renewable energy provides twenty percent of electricity generation worldwide. Hydroelectric power is the cheapest way to generate electricity today. It is a renewable source of energy and provides almost one-fifth of electricity in the world. Also, it generates electricity using a renewable natural resource and accounting for six percent of worldwide energy supply or about fifteen percent of th...

during the past decade, natural plant products as environmentally safe option have received attention for controlling phytopathogenic diseases. investigation of plants containing natural antimicrobial metabolites for plant protection has been recognized as a desirable method of disease control. the fungus fusarium oxysporum causes diseases such as root rot, damping off and fusarium wilt and it ...

Pathogens have evolved elaborate mechanisms to invade plant tissues and cause disease. Plants, in turn, respond to pathogen infection by expressing multiple layers of resistance. Once low energy ‘basal’ defences of plant cells have been overcome by pathogens, the plant can employ a more energy costly system of nonself recognition that triggers an ‘acute’ immune response. The survival of plants ...

In "gene-for-gene" interactions between plants and their pathogens, incompatibility (no disease) requires a dominant or semidominant resistance (R) gene in the plant, and a corresponding avirulence (Avr) gene in the pathogen. Many plant/pathogen interactions are of this type. R genes are presumed to (a) enable plants to detect Avr-gene-specified pathogen molecules, (b) initiate signal transduct...

Fruits are one of the most important sources of polyphenols for humans, whether they are consumed fresh or as processed products. To improve the phenolic content of fruits, a novel field of interest is based on results obtained using elicitors, agrochemicals which were primarily designed to improve resistance to plant pathogens. Although elicitors do not kill pathogens, they trigger plant defen...
