#Arabidopsis root growth is known to be suppressed under low Pi conditions. Here, Zhang et al. report that this #growth inhibition is caused by the collapse of #auxin transport in the presence of accumulated iron.

Genetics of Alternating Sexes in Walnuts

Scientists have uncovered a genetic mechanism in walnuts and their ancestors that has remained stable for 40 million years. Male-first or female-first flowering, balanced by a single genetic locus, parallels sex determination in animals. This evolutionary trait ensures genetic diversity, with distinct pathways evolving independently in walnuts and pecans.

Twisted pollen tubes induce infertility in Plants

Plants with multiple sets of chromosomes have advantages over their relatives with a double set. But why they often start out infertile was only partially understood. Biologists have now discovered a new reason for the initial difficulties.

Wounded plants: how they coordinate their healing

In a new study, scientists unraveled the mystery behind how wounded plants coordinate their healing. By investigating the role of the hormone Auxin and pressure changes, they discovered the intricate cellular mechanisms guiding plant regeneration. This understanding sheds light on how plants adapt and survive in challenging environments.
