The blossoms of maturity
Plants normally flower in response to seasonal changes, such as those associated with the end of winter or beginning of spring. Scientists at the Max Planck Institute for Developmental Biology have now identified a signaling pathway that allows plants to blossom even without positive signals from the environment. The concentration of a small RNA snippet in plants cells operates like an hour glass: a decline in its level awakes the plant from its vegetative dormancy and allows it to enter the reproductive mode. (2009-08-20)

Mechanism discovered for plants to regulate their flowering in a warming world

Why spring is blooming marvelous (and climate change makes it earlier)
With buds bursting early, only for a mild winter to turn Arctic and wipe them out, we are witnessing how warm weather can trigger flowering, even out of season, and how important it is for plants to blossom at the right time of year. In research to be published in the journal Nature, scientists from the John Innes Centre have identified the switch that accelerates flowering time in response to temperature. (2012-03-21)

Solving Darwin's 'abominable mystery': How flowering plants conquered the world
In a study publishing on Jan. 11 in the open access journal PLOS Biology, researchers found that flowering plants have small cells relative to other major plant groups, made possible by a greatly reduced genome size, and this may explain how they became dominant so rapidly in ecosystems across the world. (2018-01-11)

A protein prevents plants from premature flowering
The induction of flowering is of major importance from an ecological and agronomic point of view. Environmental factors regulate flowering time, the mechanisms of which have been the subject of many studies. A team from the University of Geneva (UNIGE) has discovered that UV-B, a type of radiation that is a natural component of sunlight can be a powerful inducer of flowering, but that a protein called RUP2 blocks their action to prevent early flowering. (2018-09-27)

Flower power makes tropics cooler, wetter
The world is a cooler, wetter place because of flowering plants, according to new climate simulation results published in the journal Proceedings of the Royal Society B. The effect is especially pronounced in the Amazon basin, where replacing flowering plants with non-flowering varieties would result in an 80 percent decrease in the area covered by ever-wet rainforest. (2010-06-16)
