“…However, this enzymatic activity has been previously described in the amorphous material and membrane complexes that surround the paracrystalline structure in mosquito spermatozoon (Báo et al, 1992). This result indicates that the activity of cytochrome C oxidase occurs mainly in the early phase of spermatid differentiation and that this enzyme is not essential for the final stages of differentiation, or for the flagellum movement (Baccetti et al, 1973).…”

“…In addition, glucose-6-phosphatase activity has been shown in the endoplasmic reticulum and Golgi complex of rat (Thorne-Tjolmsland et al, 1991) and insects spermatids (Báo & de Souza, 1994;Furtado & Báo, 1996) and in the axoneme and mitochondrial compartments of spermatozoa of some invertebrate and vertebrate species (Anderson & Personne, 1970;Bigliardi et al, 1970). The existence of such enzymatic activity to cytochrome C oxidase in the mitochondrial derivatives has been previously described in insects (Anderson & Personne, 1970;Bigliardi et al, 1970;Baccetti et al, 1973;Báo et al, 1992).…”

“…Our observations show the presence of cytochrome C oxidase activity only in mitochondrial cristae. In insect sperm, the paracrystalline structure does not seem to have cytochrome C oxidase activity as is usually found in mitochondrial cristae (Bigliardi et al, 1970;Baccetti et al, 1973;Perotti, 1973). However, this enzymatic activity has been previously described in the amorphous material and membrane complexes that surround the paracrystalline structure in mosquito spermatozoon (Báo et al, 1992).…”

Ultrastructural localization of enzymatic activity during spermiogenesis in two phytophagous bugs (Hemiptera: Pentatomidae)A.P. Fernandes S. N. Báo Abstract Ultrastructural cytochemical techniques were used for the localization of phosphatases and oxidases in spermatid and spermatozoon of the phytophagous bugs Acrosternum aseadum and Nezara viridula (Hemiptera: Pentatomidae). Acid phosphatase was found mainly in the trans most portion of the Golgi complex, and in the acrosome of spermatozoon. Glucose-6-phosphatase was located in the endoplasmic reticulum, trans portion of the Golgi complex and in the acrosome of spermatids. The axoneme showed activity of acid phosphatase, glucose-6-phosphatase and thiamine pyrophosphatase. This observation supports the idea that various phosphates may play some role in spermatid differentiation. Indeed, the presence of cytochrome oxidase activity was only shown in the mitochondrial cristae of early spermatids, suggesting also the participation of this enzyme during spermatid differentiation of this insect.

Stretch‐activated calcium channels relay fast calcium waves propagated by calcium‐induced calcium influx

For nearly 30 years, fast calcium waves have been attributed to a regenerative process propagated by CICR (calcium-induced calcium release) from the endoplasmic reticulum. Here, I propose a model containing a new subclass of fast calcium waves which is propagated by CICI (calcium-induced calcium influx) through the plasma membrane. They are called fast CICI waves. These move at the order of 100 to 1000 µm/s (at 20 • C), rather than the order of 3 to 30 µm/s found for CICR. Moreover, in this proposed subclass, the calcium influx which drives calcium waves is relayed by stretch-activated calcium channels. This model is based upon reports from approx. 60 various systems. In seven of these reports, calcium waves were imaged, and, in five of these, evidence was presented that these waves were regenerated by CICI. Much of this model involves waves that move along functioning flagella and cilia. In these systems, waves of local calcium influx are thought to cause waves of local contraction by inducing the sliding of dynein or of kinesin past tubulin microtubules. Other cells which are reported to exhibit waves, which move at speeds in the fast CICI range, include ones from a dozen protozoa, three polychaete worms, three molluscs, a bryozoan, two sea urchins, one arthropod, four insects, Amphioxus, frogs, two fish and a vascular plant (Equisetum), together with numerous healthy, as well as cancerous, mammalian cells, including ones from human. In two of these systems, very gentle local mechanical stimulation is reported to initiate waves. In these non-flagellar systems, the calcium influxes are thought to speed the sliding of actinomyosin filaments past each other. Finally, I propose that this mechanochemical model could be tested by seeing if gentle mechanical stimulation induces waves in more of these systems and, more importantly, by imaging the predicted calcium waves in more of them.

The generation and propagation of double waves in mosquito (Aedes notoscriptus) sperm‐tails

In the mosquito Aedes notoscriptus nine accessory tubules develop from the doublets of the axoneme whose single central fibre forms late in spermiogenesis. The 9 + 9 + 1 mosquito sperm‐tail propagates two waves of differing frequency and amplitude. The structural basis for the movement is of interest. Mosquito sperm were demembranated until all movement ceased and were reactivated with a solution containing adenosine triphosphate (ATP). They immediately moved in a normal fashion. Like untreated sperm, they always propagated double waves. This indicates that the plasma membrane does not control the double wave. After sonicating sperm treated as above, the high‐frequency, low‐amplitude waves sometimes propagated alone beyond a damaged region of sperm‐tail, whereas the large‐amplitude, low‐frequency waves never propagated alone beyond a damaged region. This suggests that the latter waves are generated by an anterior site, possibly the centriole or centriole adjunct. The structure that propagates the large amplitude wave is not known; possibly the accessory tubules may slide against the axonemal doublets. Any region of the sperm‐tail is capable of generating and propagating the low‐amplitude, high‐frequency wave, for which the structure responsible is probably the axoneme.
