"This fusion created an entirely new protein that took on a central role in the auxin signaling pathway," says Dolf Weijers, Professor of Biochemistry. The chromatin factor enables ARF proteins to ...

Spatial control of phytohormone signaling within the primary root There are many cases of regulation between hormone pathways that do not involve auxin 3 (Fig. 1). However, it appears that plants ...

As they suspected from previous work in other plant species, the auxin pathway was more active on the shady side of the stem where it could promote growth and bending toward the light. 3 However, ...

Upon reception, these N signals intricately interact with phytohormones, such as auxin and brassinosteroid, either directly or indirectly influencing their synthesis, sensing, signaling ...

Signaling via Endosomes Many receptors ... Coordinated polar localization of auxin efflux carrier PIN1 by GNOM ARF GEF. Science 286, 316–318 (1999). Sutter, J. U. et al. Abscisic acid triggers ...

Just like phototropism, gravitropism is also caused by an unequal distribution of auxin. When a stem is placed horizontally, the bottom side contains more auxin and grows more - causing the stem ...

In a stem, the cells on the shaded side contain more auxin and grow longer than the cells on the light side. This causes the stem to grow towards the light. It is vital to note that the plant does ...
