Blast, Pyricularia grisea (Cooke) Sacc., is one of the most destructive diseases of rice worldwide and canresult in significant reductions in yield. The use of resistant cultivars is the most economical and effectiveway of controlling rice blast. A variety of DNA markers, including plant defense-related candidategene markers are available for genetic characterization and molec...

Immunogenetic differences are identified comparative characteristic farms behind frequencies spectrum alleles genetic blood group systems has been carried out. population owns peculiar immunogenetic profile in context ...

Balancing protein expression is critical when optimizing genetic systems. Typically, this requires library construction to vary the genetic parts controlling each gene, which can be expensive and time-consuming. Here, we develop sRNAs corresponding to 15nt 'target' sequences that can be inserted upstream of a gene. The targeted gene can be repressed from 1.6- to 87-fold by controlling sRNA expr...

We use a microscopic model of population dynamics, a modified version of the well known Penna model, to study some aspects of microevolution. This research is motivated by recent reports on the effect of selective hunting on the gene pool of bighorn sheep living in the Ram Mountain region, in Canada. Our model finds a sharp transition in the structure of the gene pool as some threshold for the ...
