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 ...

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.

Plants have a remarkable capacity to adjust their growth and development to elevated ambient temperatures. Increased elongation growth of roots, hypocotyls, and petioles in warm temperatures are ...

Auxin is the first plant hormone—or "phytohormone"—ever identified, with its discovery dating to the late 19 th and early 20 th centuries. With its discovery, scientists began to understand how small, ...
