Caption Effect of auxin on plant cells with regard to the transcriptional regulators "MONOPTEROS" and "BODENLOS": MONOPTEROS (MP) controls its own expression and the expression of its inhibitor ...

STUDIES on the mechanism by which auxin exerts its growth-promoting action on plant cells have indicated that, although ultimately detectable on the cell-wall, the effect is exerted in the first ...

Auxins have the opposite effect in roots. This is negative phototropism. In a root the shaded side contains more auxin but grows less. This causes the root to bend away from the light.

However, certain bacteria can hack this system. Another key player in this evolutionary back-and-forth are plant hormones ...

Auxin also has a prominent role in shaping the ... signaling as well as to distinguish between direct and indirect effects in hormone interaction.

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 ...
