Human plant sex

This study not only reveals a new mechanism which underlies reproduction in plants, but also opens an exciting new avenue in the study of how cell-cell communication is conserved between animals and plants. For many years biologist have observed regular oscillations in several parameters that control growth of pollen tubes, such as pH concentration of proton ions and calcium ions, but the actual molecular channels that control these oscillations and their physiological output have remained elusive. Both D-Ser and GLRs are key molecular players in cell-cell communication in the animal central nervous systems, at various levels: they play a central role in memory and learning processes in the brain, and have been implicated in a wide range of neurodegenerative diseases such as multiple sclerosis, Alzheimer, Huntington's disease and others. And now, surprisingly, they also have a role in reproduction of plants.

Pollen and the science of failed plant sex

Like our plant nature, we don’t hunt, it’s too much trouble. We seduce.

Many things seem to work on rats, but we know less about their effect on humans. Learning to Speak Shrub Plants do talk about sex, but as this article in Nautilus says, more often they use molecular codes to cry for help, ward off bugs, and save each other. Slow plants is one of the reasons why the novel Semiosis is structured in chapters that sometimes jump a generation ahead. I tweaked the vegetation on Pax as much as I felt I reasonably could to speed it up, but plants are naturally slow beings.

When you read a lesson that starts with the three words: male reproductive organs, chances are the topic will be related to sex. And this is no exception, but it's probably not the sex you are envisioning.

Pollen-coated anthers on a cactus flower. Image from Wikimedia Commons. Plants have sex. As northerners dig out from under record-breaking snowfalls and eye the ground for the first crocuses and robins, folks to the south are already beginning to experience a trademark of spring and the male equivalent in the sex lives of plants : pollen season.
