Biological control or biocontrol is a method of controlling pests, whether pest animals such as insects and mites, weeds, or pathogens affecting animals or plants by using other organisms. [1] It relies on predation , parasitism , herbivory , or other natural mechanisms, but typically also involves an active human management role.
Antagonism plays a critical role in agriculture, particularly in the development of biological control agent (BCAs) to manage phytopathogens and reduce reliance on synthetic pesticides. [16] Numerous microbial antagonists, including yeasts and bacteria , are isolated from diverse environments such as soil, plants, compost, and oceans for their ...
Biopesticides usually have no known function in photosynthesis, growth or other basic aspects of plant physiology. Many chemical compounds produced by plants protect them from pests; they are called antifeedants. These materials are biodegradable and renewable, which can be economical for practical use.
Plant hormones are signalling molecules produced within the plant (i.e. they are endogenous). Hormones regulate cellular processes in targeted cells locally and can be moved to other parts of the plant. Examples of plant hormones are auxins, cytokins, gibberellin, ethylene, abscisic acid, salicylic acid and jasmonates.
The gene transfer occurs when the plant signals are induced and physical contact is made between the plant cells and the bacteria. The bacteria create a mechanism that burrows a hole and transfers the new T-DNA strand into the plant cell. The T-DNA moves into the nucleus of the plant and begins to integrate into the plants' chromosome.
The team was the first to take a deep dive into the genetics behind the crop’s nutritional properties—and make a case for why chia seeds may be one solution to the world’s hunger and ...
Amid growing anxieties surrounding reported drone sightings, the FBI has issued a warning against a new trend of pointing lasers at aircrafts.
Structure of a plant cell. Plant cells are the cells present in green plants, photosynthetic eukaryotes of the kingdom Plantae.Their distinctive features include primary cell walls containing cellulose, hemicelluloses and pectin, the presence of plastids with the capability to perform photosynthesis and store starch, a large vacuole that regulates turgor pressure, the absence of flagella or ...
