Microbial utilization of human signalling molecules

Article Abstract:

Microbes commonly utilize mimicry to subvert host cellular signalling pathways for invasion. The invading pathogens, however, constantly undergo host immune surveillance and resort to neutralizing antibodies to avoid detection and ensure their survival. Some microbes have developed mechanisms to protect receptor-binding domains from neutralizing antibodies, such as antigenic variation and host mimicry. Examples of distinct receptor/signaling systems which are known to be manipulated by pathogenic microbes are discussed.

Molecular genetics of growth and development in Populus. IV. Mapping QTLs with large effects on growth, form, and phenology traits in a forest tree

Article Abstract:

The mapping of quantitative trait loci (QTLs) for adaptive and commercially important traits in Populus F2 generation reveals that the genetic variance is caused by the 1 to 5 QTLs. The Populus F2 generation is derived by the hybridization between Populus trichocarpa and Populus deltoides. The mapping is performed using the phenotypic data obtained through a period of 2 years.
