Those in the class II category contain a C-terminal pro-peptide domain of approximately 33 amino acids [5] and are targeted to the vacuole, [6] while the class I defensins lack this domain and mature in the cell wall. Unlike their class I counterparts, class II plant defensins are relatively smaller, and their acidic C-terminal prodomain is ...
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.
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.
In plants, their accumulation can increase survival during stresses such as drought. In extreme cases, such as in bdelloid rotifers , tardigrades , brine shrimp , and nematodes , these molecules can allow cells to survive being completely dried out and let them enter a state of suspended animation called cryptobiosis .
Water stress (drought and salt stress) is one of the major environmental problems causing severe losses in agriculture and in nature. Drought tolerance of plants is mediated by several mechanisms that work together, including stabilizing and protecting the plant from damage caused by desiccation and also controlling how much water plants lose through the stomatal pores during drought.
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 ...
Class 1 endophytes are all phylogenetically related and proliferate within cool and warm season grasses. They typically colonize plant shoots where they form a systemic intercellular infection. Class 1 endophytes are mainly transmitted from host to host by vertical transmission, in which maternal plants pass fungi on to their offspring through ...
Most plants can host a variety of pathogens and are often infected by multiple species simultaneously. [2] In ecology , species competing for the same resource can influence each other in two ways: antagonism, where one pathogen harms another, and synergism, where one pathogen supports the growth of another.
