Phytoncides are a biologically active substance of plant origin that kills or inhibits growth and development of bacteria, microscopic fungi, and protozoa. Phytoncides play an important role in plant immunity and in the relationships between organisms within an ecosystem. [2] The ability to produce phytoncides is a quality common among plants.
It is the most important type of antibacterial agent for fighting bacterial infections, and antibiotic medications are widely used in the treatment and prevention of such infections. [1] [2] They may either kill or inhibit the growth of bacteria. A limited number of antibiotics also possess antiprotozoal activity.
Adult plant resistance (APR) is a specialist term referring to quantitative resistance that is not effective in the seedling stage but is effective throughout many remaining plant growth stages. [ 43 ] [ 44 ] [ 42 ] The difference between adult plant resistance and seedling resistance is especially important in annual crops . [ 45 ]
Some effectors are known to suppress host defense processes. This can include reducing the plant's internal signaling mechanisms or reduction of phytochemicals production. [8] Phytohormones are chemicals used by plants for signaling; pathogens can produce these to modify plant growth to their own advantage.
Production of antibiotics is a naturally occurring event, that thanks to advances in science can now be replicated and improved upon in laboratory settings. Due to the discovery of penicillin by Alexander Fleming, and the efforts of Florey and Chain in 1938, large-scale, pharmaceutical production of antibiotics has been made possible.
Many plant species have been studied thoroughly for their value as a source of medicine. [ 6 ] [ 7 ] They have a wide range of benefits such as anti-fever and anti-inflammatory properties, can treat diseases such as malaria and diabetes , and are used as vitamins and antibiotic and antifungal medications.
An antimicrobial is an agent that kills microorganisms (microbicide) or stops their growth (bacteriostatic agent). [1] Antimicrobial medicines can be grouped according to the microorganisms they act primarily against. For example, antibiotics are used against bacteria, and antifungals are used against fungi. They can also be classified ...
To date, work on induction of plant systemic resistance has shown that inducing plant system resistance work has important implications for basic and applied research. Induced resistance applications in melons, tobacco, bean, potato, and rice have achieved significant success. Over the past decade, the study of induced system resistance has ...
