Cyclic di-guanosine monophosphate (c-di-GMP) is a second messenger found ubiquitously in bacteria. This signaling molecule regulates a variety of physiological activities such as phototaxis and flocculation in cyanobacteria and is critical for their environmental adaptation. Although genes encoding the enzymes for synthesis and/or degradation of c-di-GMP are found in the genomes of both multicellular and unicellular cyanobacteria, little is known about the biological functions of these enzymes in cyanobacterial cells. Here we have established a robust and highly sensitive liquid chromatography tandem mass spectrometry (LC-MS/MS)-based method for c-di-GMP quantification using a cost-effective solvent, methanol. Quantification methods were validated by measuring c-di-GMP in the cyanobacterium Synechococcus elongatus PCC 7942 through spiking and recovery assays after which the method was applied to examine short-term changes in cellular levels of c-di-GMP in response to a transition from light to dark or from dark to light in S. elongatus. Results showed that a transient increase in c-di-GMP upon transitioning from light to dark was occurring which resembled responses involving cyclic adenosine monophosphate and other second messengers in cyanobacteria. These findings demonstrated that our method enabled relatively specific and sensitive quantification of c-di-GMP in cyanobacteria at lower cost.

Octopus ocellatus is a small benthic species of octopus that is easy to rear and spawns large eggs during a short life cycle. These and other features of O. ocellatus may make it an advantageous subject for a broad range of behavioral studies, including those involving various types of learning. However, no type of learning has been studied in O. ocellatus. In a successive visual discrimination task, in which a `positive' or `negative' stimulus (white or black rectangle) was presented to a subject octopus and appropriate rewards or punishments were given to the subject, the rate of `correct' responses (i.e., touches to the positive stimulus or refraining from the negative stimulus) gradually increased. Moreover, `observer' octopuses that observed another octopus performing a visual discrimination task in which reward was also given to the `incorrect' responses (touches to the negative stimulus) showed a higher ratio of incorrect responses in their test sessions. These results, coupled with the physical characteristics of O. ocellatus, indicate that this species is potentially suitable for neurogenetic and neuroembryological studies of learning.
