Therefore, the system of flowering-time control must detect the long-term trends in temperatures, even within the natural fluctuations of the environment, to ensure that they flower at the appropriate time.
There are analogies to the self-incompatibility systems of flowering plants, where molecular rather than morphological mechanisms govern reproductive compatibility (reviewed by Hiscock et al., 1996).
Turning my attention to ingestion, at bachessences.com I learned that Rescue Remedy was part of a system of 38 "flower essences" that people have been squirting under their tongues since the 1930's to manage emotions ranging from fear to despair.
He's the inventor of the "Moses Miracle" system of delivering flowers from the growers to customers' doorsteps, in water, within 72 hours of harvest.
Carnation (Dianthus caryophyllus L ., in the family Caryophyllaceae, can be found in a wide range of colors and is a model system for studies of flower senescence.
Petunia is an ideal model system for studies of flower senescence due to its short life cycle, vast genetic resources, and large number of amenities for biochemical and molecular analysis.
It is widely believed, but variably disputed, that such natural phenomena as the spirals in nautilus shells, hurricanes, and galaxies; the branching of tree limbs, leaf veins, skeletal and circulatory systems; and the distribution of flower petals and brain waves conform to something called the golden ratio, or phi — represented by the irrational number 1.618.
We consider the time domain change of eight genes involved in the flowering system of the Arabidopsis, namely CCA1, ELF4, GI, LHY, PRR5, PRR7, PRR9 and TOC1.
Put to such a stress, the system of positive and negative flowering regulators may seek new balance with outcomes that are difficult to predict.
Although we do not have genetic data to verify it, temporal patterns of sex expression strongly suggest that the heterodichogamous flowering system of Platycarya effectively enhanced mating opportunities between morphs and promoted outbreeding.
