SO ENDS this perspective on the nuanced and complicated lives of plants. It has been often stated that because they move slowly, human are often sublimely oblivious to these phenomena. But with the help of time lapse cinematography, we can appreciate a little more their animated live, growth and mating cycles. https://lnkd.in/gvP8Mxa View in LinkedIn

NEW PERSPECTIVES. "The fact that plants can recognize the shape of their neighbors and rearrange their leaf position in consequence is novel and very exciting. It could be a cooperative or an altruistic behavior in a species where populations are viscous, the other mechanism described by Hamilton (1964) allowing for kin selection, that is, where dispersal is rare enough for neighbors in a population to be closely related." https://lnkd.in/gWWRrBP View in LinkedIn

NEW PARADIGMS. "One of the objections for kin selection to actually occur in plants is that the kin recognition mechanisms were thought to be impossible in the plant kingdom (i.e. lack of sensors). This has recently been challenged by experimental studies showing differential response of root growth depending on the relatedness of neighbors, providing a major opportunity to explore new hypotheses and perspectives." https://lnkd.in/gWWRrBP View in LinkedIn

LIGHT SIGNALS. "Plants recognized kin neighbours and horizontally reoriented leaf growth, a response not observed when plants were grown with nonkin. Plant kin recognition involved the perception of the vertical red/far-red light and blue light profiles. Light signals from neighbours are known to shape a more competitive plant body. Here we show that photosensory receptors mediate cooperative rather than competitive interactions among kin neighbours by reducing the competition for local pools of resources." https://lnkd.in/gA-pj6A View in LinkedIn

GAMETE MANIPULATION. "Diploidy is a fundamental genetic feature in mammals, in which haploid cells normally arise only as post-meiotic germ cells that serve to ensure a diploid genome upon fertilization. Gamete manipulation has yielded haploid embryonic stem (ES) cells from several mammalian species but haploid human ES cells have yet to be reported." https://lnkd.in/gQeEBUz View in LinkedIn

HYBRID HAPLOID TREES. "In this study, we investigated the induction of haploid plants in ‘Hirado Buntan’ pummlo (Citrus grandis) through in-situ gynogenesis by pollination with irradiated pollens of trifoliate orange (255, 325 and 500 Gy) and ‘Tongshui 72-1 Jincheng’ sweet orange (255, 395 and 500 Gy)." http://www.sciencedirect.com/science/article/pii/S0304423816302710 View in LinkedIn

BIOLOGICAL IMPROVEMENTS. "Homozygous genotypes have great potential in breeding and genomic researches in higher plants. Induction of parthenogenesis via pollination with gamma-irradiated pollens is an efficient method to obtain haploid plants that can overcome the biological limitations of fruit trees." https://lnkd.in/g8XbsX2 View in LinkedIn
