How do plants, even if still buried underground, know that it's
their time to bloom? What signals them to begin the challenging
task of making flowers, and how do they make the variety of flower
shapes, colours, and scents? What kind of instructions does the
plant carry? Flowers enrich the beauty of meadows and gardens, but
of course, they are not there simply to please us. Biologically,
blossoms form a critical aspect of the reproductive cycle of many
plants. In this book, the distinguished scientist Maxine Singer
explains what we have pieced together about the genetics behind
flowering. She describes in a clear and accessible account the key
genes which, regulated by other genes, modulated by epigenetic
effects, and responding to environmental cues, cause plants to
flower at a particular time, and define the variety of flowers. The
remarkably intricate processes involved in making flowers have
evolved in nature alongside the pollinating birds and insects that
the flowers must attract if there is to be another generation. The
processes involved in flowering have only been unravelled in the
past twenty years, and the implications for ensuring production of
food, including fruits and seeds, are profound. This is
cutting-edge science, and we have much still to learn, but the
story being revealed that lies behind the flowers in our gardens,
parks, and fields is proving astonishing.
