"SEED DORMANCY is an important component of plant fitness that causes a delay of germination until the arrival of a favourable growth season. Dormancy is a complex trait that is determined by genetic factors with a substantial environmental influence. Several of the tissues comprising a seed contribute to its final dormancy level. The roles of the plant hormones abscisic acid and gibberellin in the regulation of dormancy and germination have long been recognized." https://lnkd.in/dgHUjzK View in LinkedIn

FOUNTAIN OF STEM CELLS. "This developmental plasticity is made possible by the supply of undifferentiated stem cells from shoot meristems through the course of a plant’s life. The floral transition is executed by the product of genes that confer floral meristem identity." https://lnkd.in/d_f7kfY View in LinkedIn

MERISTEMS ENSURE PLASTICITY. "Plants ensure that they reproduce in favourable conditions. This developmental plasticity is made possible by the supply of undifferentiated stem cells from shoot meristems through the course of a plant’s life." https://lnkd.in/d_f7kfY View in LinkedIn

ADAPTATION. "Plants meet the challenge of environmental change with developmental change as an adaptation to their sessile lifestyle. For example, many plants control the time at which they flower by monitoring and responding to environmental stimuli like light quality, daylength and temperature." https://lnkd.in/d_f7kfY View in LinkedIn

DISTINCTION. "It is the connection to the acceleration of floral initiation that distinguishes vernalization from other cold-related phenomena such as dormancy chilling and stratification. In woody perennials, floral primordia are formed during a growing season, but further development is arrested as plants enter dormancy in winter. The chilling of winter breaks dormancy, resulting in bud burst and the subsequent appearance of fully developed flowers. Stratification is the promotion of seed germination by cold, usually of only a few days duration." https://lnkd.in/d_f7kfY 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
