Structure of a translocation signal domain mediating conjugative transfer by Type IV secretion systems [PDF]
, 2013 Relaxases are proteins responsible for the transfer of plasmid and chromosomal DNA from one bacterium to another during conjugation. They covalently react with a specific phosphodiester bond within DNA origin of transfer sequences, forming a nucleo ...

A family case of fertile human 45,X,psu dic(15;Y) males [PDF]
, 2006 We report on a familial case including four male probands from three generations with a 45,X,psu dic(15;Y)(p11.2;q12) karyotype. 45,X is usually associated with a female phenotype and only rarely with maleness, due to translocation of small Y chromosomal

Cadmium accumulation and tolerance in Populus nigra and Salix alba
Biologia Plantarum, 2011 Rooted cuttings of Populus nigra L. clone Poli and Salix alba L. clone SS5 were treated for three weeks with 50 μM CdSO4 in nutrient solution. The willow showed a far higher Cd tolerance, expressed as tolerance index (Ti), than the poplar in both roots ...

Influence of N, P, and K application on Zea mays L. growth and Cu and Pb accumulation
Plant, Soil and Environment, 2011 Fertilization affects soil processes in many ways that remain unclear. The effects of N, P, and K application on plant growth and Cu and Pb accumulation were thus evaluated in a soil-maize system using five treatments: N, P, and K application; N and P ...
