Sea Slug And Algae Relationship

Despite having a rather unspectacular name, sea slugs are quite possibly some of the nearly bizarre creatures establish in nature. Remember 'Shaun the Sheep', the adorable sea slug with floppy feelers and beady optics that looks like a cartoon lamb? Co-ordinate to a new research, bizarre doesn't even cover it when information technology comes to Elysia chlorotica, a green body of water slug species, and its beliefs.

Also known as the photosynthesizing sea slug, this foliage-shaped existence tin can survive for months on sunlight much like green plants. How a marine invertebrate manages to do that has long baffled the scientific world. Every bit part of the new written report, researchers have revealed that the sea slug is capable of photosynthesis, thanks to specific genes stolen from the algae it consumes. Speaking about the find, recently published in The Biological Bulletin, Sidney K. Pierce of the University of Due south Florida said:

There is no mode on globe that genes from an alga should piece of work within an beast cell. And yet here, they do. They let the animal to rely on sunshine for its diet. So if something happens to their nutrient source, they take a way of not starving to death until they detect more algae to eat.

Chloroplasts, equally we already know, are organelles, ordinarily plant in algal and plant cells, which contain chlorophyll, a group of green pigments responsible for arresting energy from sunlight. That Elysia chlorotica incorporates chloroplasts from the alga Vaucheria litorea into its own DNA has been known to scientists since the 1970s, though the exact mechanism of this fascinating miracle was a mystery until now.

After acquiring them from the algae it has just eaten, the sea slug embeds the plant organelles into its ain digestive cells, which in plow enables it to produce food through photosynthesis for up to ix months. For the electric current research, the squad was trying to figure out how these beings manage to proceed the stolen chloroplasts functional for such long periods of time. Using highly-specialized DNA distension, sequencing as well as imaging technologies, the researchers were able to detect algal genes for chlorophyll synthesis too as chloroplast proteins in the slug's own genome. Pierce went on to explain:

This paper confirms that i of several algal genes needed to repair damage to chloroplasts, and go along them functioning, is nowadays on the slug chromosome. The gene is incorporated into the slug chromosome and transmitted to the adjacent generation of slugs… In that location is no way on earth that genes from an alga should work inside an creature jail cell. And yet hither, they do. They let the creature to rely on sunshine for its nutrition. So if something happens to their food source, they take a style of non starving to death until they detect more algae to eat.

This, according to the scientists, is really one of the few known examples of functional gene transfer between multicellular organisms. Pierce went on to say:
