Evidence for a modulation of neutral trehalase activity by Ca2+ and cAMP signal...
Souza,A.C.; De Mesquita,J.F.; Panek,A.D.; Silva,J.T.; Paschoalin,V.M.F.Saccharomyces cerevisiae neutral trehalase (encoded by NTH1) is regulated by cAMP-dependent protein kinase (PKA) and by an endogenous modulator protein. A yeast strain with knockouts of CMK1 and CMK2 genes (cmk1cmk2) and its isogenic control (CMK1CMK2) were used to investigate the role of CaM kinase II in the in vitro activation of neutral trehalase during growth on glucose. In the exponential growth phase, cmk...
Ultrastructural study of the relationship between generative and vegetative cel...
Dinis, A. M.; Mesquita, J. F.Summary InMagnolia ×soulangeana pollen grains the generative cell (GC) does not become totally free within the vegetative cell (VC), at least until the pollen tube emergence. Due to a deviation in its detachment process from the sporoderm, the opposing ends of the VC plasmalemma do not fuse themselves when the GC moves away from the intine. Consequently, the interplasmalemmic space surrounding the GC does not b...
