SO ENDS this first weekend on plant dormancy. This phenomenon is not limited to plants. It is a mechanism to allow the organism to wait for favorable conditions for growth and reproduction, by being largely quiescent. We still know relatively little about the phenomena. Next weekend we will look at the genetic findings behind dormancy. View in LinkedIn

EPIGENETIC VERNALIZATION. "Cell division appears to only be required to stabilize the epigenetic-mediated vernalization response in Arabidopsis. Moreover, a stable versus transient vernalization response differentiates monocarpic Arabidopsis from its relative, polycarpic Arabis alpina." https://lnkd.in/duazcMZ View in LinkedIn

DISCREPANCY. "The quiescence of cells during chilling-induced dormancy release has been suggested as a possible discrepancy between vernalization and dormancy release." https://lnkd.in/duazcMZ View in LinkedIn

DORMANCY RELEASE. "We focus on the release of bud dormancy and the floral transition, post-embryonic responses of shoot meristems that occur in trees. A dormant meristem is unable to resume growth under favorable conditions; however, the dormant state is quantitative with endogenous and environmental signals continually altering the depth of dormancy (propensity for growth given advantageous conditions." https://lnkd.in/duazcMZ View in LinkedIn

BIOLOGISTS debate whether viruses are alive, and have done so for a long period of time. With equal lack of resolution, they engage in endless debates about the definitions of life. Both topics are capable of making rational people apoplectic. View in LinkedIn

ENVIRONMENTAL SIGNAL. "An extended chilling period is a signal for dormancy release of shoot apical and cambial meristems of many woody plants, herbaceous plant tubers and seeds of various plants as well as for the promotion of the floral transition in both monocarpic and polycarpic plant species." https://lnkd.in/duazcMZ View in LinkedIn

EMERGENCE. "This continuum from non-life to life is an example of emergence?" https://lnkd.in/dYRg2SW View in LinkedIn

MASTER REGULATOR. "It is also not known whether the molecular nature of dormancy consists of a combination of many different factors or whether a central agent exists that functions downstream of all these factors." https://lnkd.in/dgHUjzK View in LinkedIn

MATERIAL OR FORM? "Does the essence of life concern the material out of which something is composed or the form in which that material is arranged? If the latter, is that form static or is it a process? If the latter, is that process computational? Is the property of being alive a functional property? Is it realizable in an indefinitely long list of different material substrata? Could a computer simulation of a living process ever be a realization of life, i.e., literally be alive?" https://lnkd.in/da-Njua View in LinkedIn

MOLECULAR INTERACTIONS. "Despite the progress of the last years, several major questions remain unanswered. It is for instance largely unknown how temperatures are sensed during stratification. Even more importantly, the true molecular identity of dormancy is not understood yet. Many factors influencing dormancy have been described, but it is not known for most of them how they interact and relate with each other." https://lnkd.in/dgHUjzK View in LinkedIn
