NO MUTATION ACCUMULATIONS. “Potential damage to meristems as a result of age-associated mutations is negligible, because no evidence of accumulation of somatic mutations in meristems was found in a study of bristlecone pines (Pinus longaeva) that ranged from 23 to 4713 yr of age. Special cases of even longer life span have been reported in clonal species, such as Lomatia tasmanica, an endangered species that exclusively reproduces asexually and whose clonal reproduction has been dated to an age of at least 43 600 yr.” http://onlinelibrary.wiley.com/doi/10.1111/j.1469-8137.2010.03360.x/full View in LinkedIn

DORMANCY AND LIFE SPAN. "Shefferson, while evaluating different features of long-lived and short-lived plants in relation to plant size and reproduction, provided evidence for a relationship between vegetative dormancy and life span. In particular, he proposed that dormancy is an age-related response to stressful environmental conditions, increasing the life span of plants.” http://onlinelibrary.wiley.com/doi/10.1111/j.1469-8137.2010.03360.x/full View in LinkedIn

IMMORTAL JELLYFISH. "Turritopsis dohrnii, or Turritopsis nutricula, is a small (5 millimeters (0.20 in) species of jellyfish that uses transdifferentiation to replenish cells after sexual reproduction. This cycle can repeat indefinitely, potentially rendering it biologically immortal. It originated from the Caribbean sea, but has now spread around the world." http://en.m.wikipedia.org/wiki/Biological_immortality View in LinkedIn

DORMANCY. "Some animals, such as turtles, have periods of extended dormancy accompanied by substantial metabolic depression. This prevents age-inflicted damage over long periods of time. In perennial plants, entire modules can be dormant for long periods of time and then emerge after an incident of environmental stress, pathogen attack or mechanical injury to other plant parts." http://onlinelibrary.wiley.com/doi/10.1111/j.1469-8137.2010.03360.x/full View in LinkedIn

CELL CONVERSION. "Transdifferentiation is defined as the conversion of one cell type to another." https://lnkd.in/eyqSmdD View in LinkedIn

MERISTEMS AND MODULARITY. "Agricultural and gardening practices continuously show that not only are entire plant shoots restored, but also that their growth and fruit production is increased after pruning. The only secret is to leave some vegetative meristems alive." http://onlinelibrary.wiley.com/doi/10.1111/j.1469-8137.2010.03360.x/full View in LinkedIn

TRANSDIFFERENTIATION. "Turritopsis nutricula is the only known metazoan capable of reverting completely to a sexually immature, colonial stage after having reached sexual maturity as a solitary stage. It does this through the cell development process of transdifferentiation. This cycle can repeat indefinitely, (offering) it biological immortality."

CHEMICAL MIMICRY. "We have so far discovered six novel compounds, all 2,5-dialkylcyclohexan-1,3-diones, that are involved in the orchid chemical mimicry. These ‘chiloglottones’ represent a new class of natural product so far only known from Australian sexually deceptive orchids and their pollinators." https://lnkd.in/dCtjUuU View in LinkedIn

EXQUISITE PERFUME. "In sexually-deceptive Chiloglottis, a single odour compound is responsible for attracting male thynnine wasps. Small changes in the functional group of this compound may be responsible for the species-specific attraction of wasps shown by Chiloglottis." http://jxb.oxfordjournals.org/content/59/5/1085.full.pdf View in LinkedIn

THE TRIPLE-WHAMMY SPECIAL. "A pinnacle of sexual deception is found in the demure Australian flying duck orchids (Paracaleana and Caleana). These use a triple-whammy pollination system involving a chemical cue and insectiform labellum combined with a touch-sensitive hinge on the labellum that catapults and momentarily holds the male insect against the pollination structures." http://www.sciencedirect.com/science/article/pii/S0960982208001723 View in LinkedIn
