The poly(A) tail, co-transcriptionally added to most eukaryotic mRNAs, plays an important role in posttranscriptional regulation through modulating mRNA stability and translational efficiency. The length of the poly(A) tail is dynamic, decreasing or increasing in response to various stimuli through the action of enzymatic complexes, and changes in tail length are exploited in regulatory pathway...

The translational control of many maternal mRNAs in oocytes and early embryos relies on changes in poly(A) tail length; the factors controlling poly(A) tail length are being identified in a range of species.

Objective: Yield components and genetic contribution have the most important in final yield and breeding programs of crop plants. For this purpose, 20 varieties of grapevines with Russia origin were evaluated in Urmia and Takestan research station (under full irrigation and drought stress). Methods: Twenty grapevine genotypes were evaluated in Urmia and Takestan research station (under full irr...

BACKGROUND There is increasing interest in recording tail damage in pigs at slaughter to identify problem farms for advisory purposes, but also for benchmarking within and between countries as part of systematic monitoring of animal welfare. However, it is difficult to draw conclusions when comparing prevalence's between studies and countries partly due to differences in management (e.g. differ...

the use of recent technologies for the increase of growth indexes and the plants yields is an important aspects and till now many research works for this has been done. one of these efforts is the usage of magnetic water and zeolite for the increase of yield plants. this research work is an study on the effects of magnetic water and zeolite that has been done on frame work of pore random design...
