PLANT MEMORY. Intuitively, any living creature must have a type of memory in order to successfully adapt to previous experiences, and to survive. This includes plants. We now look at sone of the research in this area, much of which is quite surprising. It is possible that you will never look at a plant again in the same way. View in LinkedIn

DRUGGED POLLINATORS. "We provide evidence that plant compounds pharmacologically alter pollinator behavior by enhancing their memory of reward. Honeybees rewarded with caffeine, which occurs naturally in nectar of Coffea and Citrus species, were three times as likely to remember a learned floral scent as were honeybees rewarded with sucrose alone." https://lnkd.in/dXh9kHF View in LinkedIn

CAFFEINATED NECTAR. "A recent study in Science found that the caffeine produced by many plants may function not only as a defense chemical, as had previously been thought, but in some cases as a psychoactive drug in their nectar. The caffeine encourages bees to remember a particular plant and return to it, making them more faithful and effective pollinators." https://lnkd.in/dvFaNgd View in LinkedIn

TREE ALTRUISM. “We injured the Douglas fir by pulling its needles off, and by attacking it with western spruce bud worm, and it then sent a lot of carbon in its network into the neighbouring ponderosa pine. "My interpretation was the Douglas fir knew it was dying and wanted to pass its legacy of carbon on to its neighbour, because that would be beneficial for the associated fungi and the community." http://www.bbc.com/news/science-environment-34849374 View in LinkedIn

PHLOEM MECHANISM. "The authors integrate recent work on a phenomenon called "cosupression," in which introduced genes can suppress expression of the plant's own genes, with other research on how plants resist viral infections and suggest that information-carrying molecules (likely RNAs) move through the plant in long tubes (phloem) and regulate cell physiology at a distance." http://science.sciencemag.org/content/279/5356/1486 View in LinkedIn

LOSS OF TEETH. "All extant Mysticeti possess baleen and they are born entirely edentulous, despite being descended from ancestors that possessed teeth. The presence of rudimentary teeth in extant mysticete fetuses reflects this ancestry, but the developmental mechanisms responsible for tooth loss in utero remain obscure." http://journal.frontiersin.org/article/10.3389/fmars.2017.00067/full View in LinkedIn

FILTER FEEDING AND TEETH. "Baleen whales, or mysticetes, include the largest vertebrates to have ever evolved. Their gigantism, evolutionary success, and ecological diversity have been linked to filter feeding. While the earliest mysticetes retained the adult, mineralized teeth present in ancestral whales, all species of living baleen whales lack teeth and instead possess baleen." https://lnkd.in/duDXgp7 View in LinkedIn
