In order to study the function of kinesin-14 motor protein KIFC1 during spermatogenesis of Procambarus clarkii, the full length of kifc1 was cloned from testes cDNA using Rapid-Amplification of cDNA Ends (RACE). The deduced KIFC1 protein sequence showed the highest similarity between Procambarus clarkii and Eriocheir senensis (similarity rate as 64%). According to the results of in situ hybridization (ISH), the kifc1 mRNA was gathered in the acrosome location above nucleus in the mid- and late-stage spermatids. Immunofluorescence results were partly consistent with the ISH in middle spermatids, while in the late spermatids the KIFC1 was distributed around the nucleus which had large deformation and formed four to six nuclear arms. In the mature sperm, KIFC1 and microtubules were distributed around the sperm, playing a role in maintaining the sperm morphology and normal function. Overexpression of P. clarkii kifc1 in GC1 cells for 24 hours resulted in disorganization of microtubules which changed the cell morphology from circular and spherical into fusiform. In addition, the overexpression also resulted in triple centrosomes during mitosis which eventually led to cell apoptosis. RNAi experiments showed that decreased KIFC1 protein levels resulted in total inhibition of spermatogenesis, with only mature sperm found in the RNAi-testis, implying an indispensable role of KIFC1 during P. clarkii spermiogenesis.

“…In the freshwater crayfish, light preferences for locomotive behavior are mediated by the compound eyes, brain photoreceptors, and caudal photoreceptors (CPRs). This photosensitive system modulates locomotive activity in the animal by different physiological mechanisms (Fernández de Miguel and Aréchiga 1992; Aréchiga and Rodríguez-Sosa 1997;Kozák et al 2009;Sullivan et al 2009;Strauss and Dircksen 2010;Rodríguez-Sosa et al 2017). Variations in light intensity throughout the day may expand by approximately nine logarithmic intensity units (Nilsson 2009).…”

The purpose of this paper is to explore the firing rate of the caudal photoreceptors (CPRs) from the sixth abdominal ganglion of the crayfish Cherax quadricarinatus. We use simultaneous extracellular recordings on left and right CPR in the isolated ganglion (n = 10). The CPRs showed an asymmetry in the spontaneous activity and light-induced response. In darkness, we observed one subgroup (70%) in which the left CPR (CPR-L) and right CPR (CPR-R) had spontaneous firing rates with a median of 18 impulses/s and 6 impulses/s, respectively. In another subgroup (20%), the CPR-R had a median of 15 impulses/s and the CPR-L had 8 impulses/s. In both groups, the differences were significant. Furthermore, the CPRs showed an asymmetrical photoresponse induced by a pulse of white light (700 Lux, 4 s). In one subgroup (30%), the CPR-L showed light-induced activity with a median of 73%, (interquartile range, IQR = 51), while the CPR-R had a median of 41%, (IQR = 47). In another subgroup (70%), the CPR-R showed a median of 56%, (IQR = 51) and the CPR-L had a median of 42%, (IQR = 46). In both groups, the differences were significant. Moreover, we observed a differential effect of temperature on CPR activity. These results suggest a functional asymmetry in both activities from left and right CPRs. These CPR activity fluctuations may modulate the processing of information by the nervous system.

The study investigated the behavior of European sea bass (Dicentrarchus labrax), in laboratory-scale conditions and controlled light environment. Fish were confined in tanks that had been previously split into two equal compartments. A tear on the net allowed fish to freely moved between the two compartments. An extra net frame, placed above tanks altered light environment to: (1) Illuminated Holding Area -Shadow Escape Area, (2) Shadowed Holding Area -Illuminated Escape Area and 3) Illuminated Holding Area -Illuminated Escape Area, as control condition, for a period of 13 days. Sea bass showed a strong preference to the illuminated compartment of the tank, from the beginning of the trials. Crossings to the shadowed compartment were regular but always followed by a reverse action to the illuminated area. In addition, they occurred in series of 7 individuals. Reverse crossings to the initial shadowed compartment were rarely observed throughout the experiment, even if fish had to suffer starvation. Behavioural results regarding sea bass light preference may have essential implications in marine biology and aquaculture, including species domestication as well as manipulation via artificial light.
