The aim of this work was to evaluate arbuscular mycorrhizal(AM)fungi as soil indicators and the mycorrhization of native and exotic tree species planted in the Acaraúbasin,a transition area from the coast to the Brazilian semiarid *** with 6-year-old trees of four native and three non-native species as well as one non-forested area were evaluated in terms of the diversity of AM fungi in the mycorrhizosphere and the root colonization by AM and ectomycorrhizal(EcM)***-four AM fungi were identified;claroideoglomus etunicatum,Glomus sinuosum,Paraglomus albidum,Acaulospora laevis,and Acaulospora brasiliensis were abundant in the forest ***,dominance,evenness and richness indices of AM fungi were higher in plots with native *** root samples were colonized by AM fungi and only A nadenanthera colubrina,Acacia mangium,casuarina equisetifolia and Eucalyptus urophylla formed associations with EcM *** morphotypes served as soil indicators for coverings with the native species Astronium fraxinifolium and colubrina *** species may favor the proliferation of rarer AM *** fungi–plant relationships may be important in the management of forest systems,and the evidence with mycorrhizal associations allows the inclusion of Brazilian species in tropical reforestation.

Luminal acidification in the epididymis is an important process for the regulation of male fertility. Low pH and low bicarbonate concentration are among key factors that keep spermatozoa in a dormant state while they mature and are stored in this organ. Although significant bicarbonate reabsorption is achieved by principal cells in the proximal regions of the epididymis, clear and narrow cells are specialized for net proton secretion. clear cells express very high levels of the vacuolar proton pumping ATPase （V-ATPase） in their apical membrane and are responsible for the bulk of proton secretion. In the present paper, selected aspects of V-ATPase regulation in clear cells are described and potential pathologies associated with mutations of some of the V-ATPase subunits are discussed. （Asian J Androl 2007 July; 9： 476-482）
