glaciares

They were able to resurrect plants of more than four centuries

Many times we give you advice about the correct way to care for your plants, the best way to water them, put pesticides, prune them, etc. Today, however, we want to share with you a very particular novelty.

They have been able to resurrect plants that they were buried under the ice for more than four centuries. A curiosity linked to plants that is interesting to know.

Some mosses had been frozen under the Teardrop Glacier in Canada, since the Little Ice Age, which took place between 1550 and 1850. They have now been able to grow back in the hands of scientists from the University of Alberta.

<p style=The discovery has been very important since the ability to regenerate bryophyte plants is important for the recolonization and maintenance of polar terrestrial ecosystems.

The study has been presented at PNAS, detailing the work of Canadian researchers. The work confirmed that the plants that had been buried under a glacier were treated with radiocarbon.

The variety of samples of exhumed bryophytes of 60 species, eleven cultures of bryophytes came to be able to grow thanks to in vitro treatments. The plants belong to four different species, they are: Aulacomnium turgidum, Distichium capillaceum, Encalypta procera Y Syntrichia rural.

With this work it is possible to demonstrate the totipotent capacity of bryophytes, the ability of cells to dedifferentiate to a meristematic state analogous to that of stem cells and to develop a new plant.

Let us keep in mind that bryophytes are poikilohydric, they have no mechanism to control the water content. This ability is what allows you to stay asleep in the case of desiccation and be able to revive when the conditions are again favorable.
