A soil bacterium alters sex determination and rhizoid development in gametophytes of the fern Ceratopteris richardii

The soil environment that natural populations of plants are exposed to is quite complex. Bacteria represent major players in the soil with cell numbers...

Sexual dimorphism and rapid turnover in gene expression in pre-reproductive seedlings of a dioecious herb

Sexual dimorphism in morphology, physiology or life history traits is common in dioecious plants at reproductive maturity, but it is typically inconspicuous or absent...

Amborella trichopoda helps reveal features of the first flowering plants

It's difficult to peer into the past to see the first flowering plant, but Charlie Scutt shows how an ancestor in the modern-era provides some clues as to what it looked like.

Genetic sex determination and sexual instability in Amborella trichopoda

Amborella trichopoda, the sister species of all other extant angiosperms, is typically dioecious, producing male and female flowers on separate individuals. Anger et al....

Environmental regulation of sex determination in oil palm (Review)

In the African oil palm, Elaeis guineensis, male and female inflorescences are produced separately in an alternating cycle that is influenced by the environment:...

Botany for Halloween – Witches, Brooms and Pumpkins

At the moment, I am teaching plant hormones in our course on plant cell and developmental biology (BS1003). Fortunately, hormones and development link well...

Flower unisexuality in dioecious date palm

Dioecy has evolved independently several times during the evolution of flowering plants, but knowledge of the mechanisms involved is poor. Phoenix dactylifera is a...

L-Cucumber’s leaf prototype mimics leaf shape of stressed plants.

How does variation in traits of Tunisian oak seeds affect survival?

Oaks are the dominant species of tree in many Mediterranean forests. However, the climate of the Mediterranean basin is predicted to change...

How Important Is Leaf Realism in Functional-Structural Plant Modelling?

Making a realistic plant in a computer model is possible, but is it necessary. All the computations generating the plant slow down...
