To validate that the flower was the organ sensing the vibration of the pollinator, an experiment was run where the flowers were covered with a glass jar, while the rest of the plant was exposed. Sugar concentration of nectar showed no significant difference before and after the low frequency sound was played. [ 10 ]
Nicotiana attenuata’s genome is ~2.26 Gb long, [2] significantly more than the plant model species Arabidopsis thaliana.Preferential gene retention after a genome-wide duplication event in the genus Nicotiana partially accounts for this large size, which is roughly twice that of N. obtusifolia (~1.23 Gb), a closely related species.
Plant perception is the ability of plants to sense and respond to the environment by adjusting their morphology and physiology. [1] Botanical research has revealed that plants are capable of reacting to a broad range of stimuli, including chemicals, gravity, light, moisture, infections, temperature, oxygen and carbon dioxide concentrations, parasite infestation, disease, physical disruption ...
In buzz pollinated plants, this process can only happen if pollinators visit the flowers to extract pollen. Only a few insect species are able to pollinate these plants. The flower morphology of buzz pollinated plants is different from that of other flora that do not use this type of pollination.
The resulting photographs of standing wave patterns are striking. Lauterwasser's book focused on creating detailed visual analogues of natural patterns ranging from the distribution of spots on a leopard to the geometric patterns found in plants and flowers, to the shapes of jellyfish and the intricate patterns found on the shell of a tortoise.
This allows plants that may require an animal pollinator to stand out from other flowers or distinguish where their flowers are in a muddied background of other plant parts. [5] For the plant, it is important to share and receive pollen so they can reproduce, maintain their ecological role, and guide the evolutionary history of the population.

Fluorescence resonance energy transfer, also known as Förster resonance energy transfer (FRET in both cases) is the term given to the process where two excited "fluorophores" pass energy one to the other non-radiatively (i.e., without exchanging a photon). By carefully selecting the excitation of these fluorophores and detecting the emission ...
