EPIGENETIC SIGNALS. “Flowering plant development is wholly reliant on growth from meristems, which contain totipotent cells that give rise to all post-embryonic organs in the plant. Plants are uniquely able to alter their development throughout their lifespan through the generation of new organs in response to external signals.” https://bmcbiol.biomedcentral.com/articles/10.1186/1741-7007-3-12 View in LinkedIn

BODY PLAN FLEXIBILITY. “Plant development is remarkably plastic. Groups of totipotent cells termed meristems, which are maintained throughout the life of the plant, give rise to all post-embryonic organs from roots and leaves to petals and fruit. This allows plants, unlike metazoans, to change their final body plans dramatically in response to environmental, hormonal and nutritional cues.” https://lnkd.in/gjRTTC9 View in LinkedIn

CONTROL OF MERISTEMS. “Meristems continually supply new cells for post-embryonic plant development and coordinate the initiation of new organs, such as leaves and flowers. Meristem function is regulated by a large and interconnected dynamic system that includes transcription networks, intercellular protein signalling, polarized transport of hormones and a constantly changing cellular topology.” https://lnkd.in/gBriN3x View in LinkedIn

LIFELONG. “Organogenesis is a postembryonic process that occurs in a continuous manner throughout the entire lifespan.” https://lnkd.in/gVEbgeX View in LinkedIn

PLANT STEM CELLS. “In plants, postembryonic development is organized by meristems, which both self-renew and produce daughter cells that differentiate and give rise to different organ structures.” https://lnkd.in/gVEbgeX View in LinkedIn

SO ENDS this two weekend venture into the important differences between plants and animals. Plants are considerably dissimilar in many ways. Plants are in so many ways more like an alien species than they are like the animal world. Habituation to plants makes us blind to see the considerable differences of these splendidly different creatures who we share the planet with. See our green fellow travelers with fresh eyes enabled by the mind. View in LinkedIn

NUANCED CONTROL. “Epigenetic phenomena reflect alternative gene expression states that are maintained through multiple rounds of mitosis, and sometimes through meiosis. The alternative expression states are not due to mutation or changes in gene sequence and are reversible to varying degrees.” https://lnkd.in/gJYMEr2 View in LinkedIn

NO MASS CELL MIGRATION. “Plant cells do not slide or slip relative to one another. Organogenesis in flowering plants thus results almost entirely from patterned control of the numbers, places, and planes of cell divisions, coupled with regulated and coordinated cellular expansion.” http://www.sciencedirect.com/science/article/pii/S0092867400818681 View in LinkedIn

CELL DEATH. “Plants do not use the standard animal mechanisms of cell migration and migration of sheets of cells, and although plants use programmed cell death in many ways, they do not appear to use it to achieve appropriate cell numbers in developing organs or stem cell populations.” https://lnkd.in/gpVeCM3 View in LinkedIn
