This review focuses on the evolution of plant hormone signaling pathways. Like the
chemical nature of the hormones themselves, the signaling pathways are diverse. Therefore …

The colonization of land by plants shaped the terrestrial biosphere, the geosphere and
global climates. The nature of morphological and molecular innovation driving land plant …

Auxins are hormones that have central roles and control nearly all aspects of growth and
development in plants,–. The proteins in the PIN-FORMED (PIN) family (also known as the …

Colonization of land by plants was a major transition on Earth, but the developmental and
genetic innovations required for this transition remain unknown. Physiological studies and …

Auxin plays crucial roles in multiple developmental processes, such as embryogenesis,
organogenesis, cell determination and division, as well as tropic responses. These …

Auxin controls almost every aspect of plant development. Auxin is distributed within the plant
by passive diffusion and active cell-to-cell transport. PIN-FORMED (PIN) auxin efflux …

The phytohormone auxin influences virtually all aspects of plant growth and development.
Auxin transport across membranes is facilitated by, among other proteins, members of the …

From embryogenesis to fruit formation, almost every aspect of plant development and
differentiation is controlled by the cellular accumulation or depletion of auxin from cells and …

The bulk polar movement of the plant signaling molecule auxin through the stem is a long-
recognized but poorly understood phenomenon. Here we show that the highly polar, high …

The phytohormone auxin has been shown to be of pivotal importance in growth and
development of land plants. The underlying molecular players involved in auxin …
