SIMILAR SOLUTIONS. "Strikingly, despite their independent evolutionary routes, seagrasses from the three different lineages have evolved many similar morphologies, life history strategies, and breeding systems. This indicates that the aquatic habitat imposes novel selection forces that can lead to parallel evolution." http://bmcevolbiol.biomedcentral.com/articles/10.1186/1471-2148-11-8 View in LinkedIn

POTASSIUM. "Key metabolic processes in the cytoplasm such as enzymatic reactions, protein synthesis, and ribosome functions rely on K+ as a co-factor. An increased level of Na+ creates a competing environment for K+ binding sites and thus decreases efficiency of these processes. Moreover, detrimental effects can propagate from the cytoplasmic compartment into the chloroplasts, leading to a decreased efficiency of photosynthesis which in turn impairs growth." http://bmcevolbiol.biomedcentral.com/articles/10.1186/1471-2148-11-8 View in LinkedIn

SALT TOXICITY. "Specific to marine environments, seagrasses are often exposed to high salt levels and short-term salinity fluctuations in the coastal and estuarine system. Increased levels of sodium (Na+) are known to be toxic, partly due to the fact that both Na+ and potassium (K+) have very similar physicochemical properties." http://bmcevolbiol.biomedcentral.com/articles/10.1186/1471-2148-11-8 View in LinkedIn

FRAGMENT FROM NATURE continues from last weekend and concludes this weekend on the return of seagrasses to the water after their epic conquest of terrestrial habitats on leaving the sea. This is the plant equivalent of the whale journey, and no less difficult genetically, biochemically, metabolically, and anatomically. On leaving the sea for the land they became different organisms, and so with their return to the sea. It is an epic story in the true sense of the word, impressive in scope and achievement, the Iliad of the plant world. View in LinkedIn

ATTENTION. "On the other hand, attention is a feature of intelligent conduct in the present, whereby an organism selectively responds to ever-shifting stimuli in a way that allows it to maintain adequate levels of adaptation to its environment. Before processing, evaluating and communicating information, plants must first attend to—or take note of—the bits that are relevant to their optimal growth and development." http://www.tandfonline.com/doi/full/10.4161/psb.23902#abstract View in LinkedIn

PAST-BIASED MARKER. "Studies of plant intelligence have tended to concentrate on memory as a benchmark of intelligent behavior. Although memory has a bearing on all three modalities of time, including a remembered past event, the present of storage and the possibility of future retrieval, it is a marker of intelligence heavily biased toward the past." http://www.tandfonline.com/doi/full/10.4161/psb.23902#abstract View in LinkedIn
