Ferns switch between male and hermaphrodite forms, a process driven by chemical signals. Research shows the plant hormone auxin is key, triggering new growth centers when a male signal is absent.

Auxin, a pivotal plant hormone, orchestrates a wide range of developmental processes including cell division, elongation, organ formation and responses to environmental stimuli. Its signalling ...

The direction of auxin transport changes in gravistimulated roots, causing auxin accumulation in the lower side of horizontally reoriented roots. This study found that auxin was similarly involved in ...

Scientists have uncovered how the plant hormone auxin helps roots bend and downwards towards gravity – a process called gravitropism - even after encountering obstacles in soil. Experts from the ...
