avirulent उदाहरण वाक्य

ETI is a strong immune response that efficiently protects plants from avirulent biotrophic pathogens and is often associated with the hypersensitive reaction ( HR ), a form of programmed death of plant cells at infection sites.
Virulent isolates proceed through the ( 3-indolylmethyl ) dithiocarbamate " S "-oxide intermediate, while avirulent isolates first convert brassinin to " N "-acetyl-3-indolylmethylamine and 3-indolylmethylamine.
The Ti plasmid is lost when " Agrobacterium " is grown above 28 �C . Such cured bacteria do not induce crown galls, i . e . they become avirulent . pTi and pRi share little sequence homology but are functionally rather similar.
The S form is more virulent, and bears a subcutaneously with S form, mice succumbed to pneumonia and death within several days . However, the R form, lacking a capsule its outer surface being cell wall is relatively avirulent, and does not cause pneumonia as often.
The Treanor et al . study was on vaccine produced from the human isolate ( A / Vietnam / 1203 / 2004 H5N1 ) of a virulent clade 1 influenza A ( H5N1 ) virus with the use of a plasmid rescue system, with only the hemagglutinin and neuraminidase genes expressed and administered without adjuvant . " The rest of the genes were derived from an avirulent egg-adapted influenza A / PR / 8 / 34 strain.
