Báo cáo khoa học: Hydrogen independent expression of hupSL genes in Thiocapsa roseopersicina BBS pot

... and hupUV genes are apparently intact, yet the hydrogen sensing system is not functional in T. roseopersicina BBS. Results Hydrogen independent hupSL expression The HupSL enzyme of T. roseopersicina ... roseopersicina is in apparent contradiction with the absence of a hydrogen- dependent regulation of HupSL expres- sion. In order to examine in detail the...

In particu- lar, the system now generates more pronouns in French than before, confirming the advantage of using a combination of preprocessing ... translated by a masculine overt pronoun in French still remains. Finally, rates of missing pronouns also de- creased. In this case, improvements are signif- icant: we obt...
