Scientists discovered that tobacco plants alter their flower opening time in response to insect herbivory, reducing scent emission and attracting hummingbirds as an alternative pollinator. This adaptation helps protect the plant from harm while still allowing for fertilization and reproduction.
Researchers found that the ridges form from cutin polyester, not from underlying surfaces. The discovery could lead to enhanced pollination success and production of polyesters or related chemicals by genetically manipulating plants or microbes.
Researchers explore the development and morphology of insect-mimicking spots on the flower petals of a South African beetle daisy. The study found that these spots are composed of three types of epidermal cells, each spanning four fused petal lobes, and are influenced by UV reflectivity and anthocyanin pigment.
The University of Leeds team is developing a digital model to predict the timing of plant flowering, which could help farmers improve crop yields. The model uses computer simulations to account for changes in genetic structure and environmental factors like climate.
The study compares genetic structures of Arabidopsis thaliana and Persea americana to understand how the first flowering plants evolved from non-flowering plants. Researchers found significant overlap among organ types, suggesting a genetic 'fossil' that allowed for flower transformation.
Grapevine flowers' fragrance comes from pollen grains stored in anthers, contrary to common perception that petals produce perfume. The scent serves as a defense mechanism to protect male reproductive tissues from predatory insects.
Researchers recorded moth brain activity as they smelled individual chemicals from sacred datura flowers. Only nine chemicals provoked a neural response, but all nine were necessary for the moths to fly to and feed on the flowers. This study provides insight into how insects process smells and may apply to human olfactory perception.
A new study identifies a genetic pathway that determines the pattern of flower growth in tomato plants. The researchers found that manipulation of this pathway can turn a single stem into hundreds of branch-bearing shoots, increasing crop yields.
A gigantic palm has been discovered in Madagascar with an unusual and spectacular lifecycle, growing up to 18m high and dying after fruiting. Conservation efforts are underway to protect this critically endangered species, with the aim of disseminating it to botanic gardens and growers globally.

Biologists at UCSD discover how to genetically convert leaves into petals, a process made possible by the expression of five genes in leaves. The achievement has significant implications for plant development and could lead to the creation of novel plants with colorful, petal-like structures.
Researchers at Purdue University have discovered that snapdragons release more scent during the day when bees are active, and that this relationship between the flower and bee is crucial for pollination. The study also found that a genetic regulatory mechanism controls the production of floral scents in different plant species.
A team of biologists at UCSD identified three genes that produce the 'double flower' abnormality, which is prized for its attractiveness. Normal flowers consist of four rings or whorls; when these genes are mutated, petals, stamens and carpels are converted into sepals, resulting in a double-flower character.
Researchers at the University of Chicago Medical Center have identified a mutation in a small flowering plant that disrupts male-female communication, leading to pollen tubes wandering aimlessly. This defect is similar to self-sterility observed in many plant species, which helps maintain genetic diversity.
