TRANSPIRATION. "A new study estimates that 80 to 90 percent of the atmospheric water vapor originating from Earth's continents comes from plant transpiration rather than simple physical evaporation. This process uses up almost half of the solar energy absorbed by our landmasses and represents a major piece of our terrestrial climate system." https://lnkd.in/dKcjbbW View in LinkedIn

GLOBAL PHOTOSYNTHESIS. "The team revised the rate of global photosynthesis upward. The rate is expressed in terms of how much carbon is processed by plants in a year. From the previous estimate of 120 petagrams of carbon a year, the team set the annual rate between 150 and 175 petagrams.” (One petagram equals one trillion kilograms). https://lnkd.in/dzpW9-Q View in LinkedIn

INEVITABLE. "Swiss Government's Federal Ethics Committee on Non-Human Biotechnology concludes that plants have rights, and we have to treat them appropriately. A majority of the panel concluded that "living organisms should be considered morally for their own sake because they are alive." https://lnkd.in/dgH-auZ View in LinkedIn

DIFFERENT TIME SCALES. "Midwinter, and the countryside is so still, it seems almost lifeless. But these trees and bushes and grasses around me are living organisms just like animals. And they have to face very much the same sort of problems as animals face throughout their lives if they're to survive. They have to fight one another, they have to compete for mates, they have to invade new territories. But the reason that we're seldom aware of these dramas is that plants of course live on a different time-scale." (David Attenborough). https://lnkd.in/dUFDzhT View in LinkedIn

MOLECULAR ADAPTATION. "These adaptations are possibly associated to the above mentioned Na+ toxicity which seagrasses have likely experienced during their evolution towards the marine environment. To this respect, molecular adaptation of key cellular processes known to be sensitive towards increased ionic levels such as photosynthesis, translation, and selected metabolic enzymes are expected." http://bmcevolbiol.biomedcentral.com/articles/10.1186/1471-2148-11-8 View in LinkedIn

KEY GENES. "Positive selection for 51 genes was detected after the split from terrestrial monocots based on a maximum likelihood approach. In the present analysis, many of the identified PSGs are involved in the central biological pathways of translation, photosynthesis, and glycolysis." (PSGs= positively selected genes). http://bmcevolbiol.biomedcentral.com/articles/10.1186/1471-2148-11-8 View in LinkedIn

PARALLEL SOLUTIONS. "Seagrasses have been found to share morphological traits that distinguish them from terrestrial plants such as reduced stamen and corolla, and elongated pollen without exine walls. Except for the genus Enhalus with above-surface pollination, all of the 60 seagrass species exhibit true sub-aqueous pollination by means of filiforme pollen (hydrophily). This adaptation to a marine habitat is thus an example of morphological parallel evolution." http://bmcevolbiol.biomedcentral.com/articles/10.1186/1471-2148-11-8 View in LinkedIn

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
