AZGs: a new family of cytokinin transporters Cytokinins (CKs) are phytohormones structurally similar to purines that play important roles in various aspects of plant physiology and development. The local and long-distance distribution of CKs is ...

And finally, a brief piece reviewing and discussing how AZGs fit into the CK signaling scenario in #BiochemSocTrans. For more details, feel free to DM!

In summary, AZGs are not only important for CK transport and its signalling, but they represent hubs for auxin:CK crosstalk at different levels.

And personally it's great to see how the work of so many years is validated by a different approach on the other side of the globe🌍

AZG1 is a cytokinin transporter that interacts with auxin transporter PIN1 and regulates the root stress response An environmentally responsive root system is crucial for plant growth and crop yield, especially in suboptimal soil conditions. This responsiveness enables the plant to exploit regions of high nutri...

Then, was the time for AZG1. Despite a high level similarity to AZG2, AZG1 has a different mechanism to transport CK. But, what makes AZG1 specially interesting is that its presence is important for the stability of the auxin transporter PIN1.

Arabidopsis AZG2 transports cytokinins in vivo and regulates lateral root emergence Cytokinin and auxin are key regulators of plant growth and development. During the last decade transport mechanisms have turned out to be the key for the control of local and long-distance hormone...

First, we described that AZG2 can take up CK with high affinity. AZG2 expression is tightly regulated (by auxins 🧐), being present only in a few cells surrounding lateral root primordia. In these cells, AZG2 activity is important for CK signaling.

This is amazing! Few years back we showed that AZGs transport CKs in Arabidospsis and that they have an special place in the auxin:CK signalling crosstalk. Now, we can see how they do it to the most precise detail πŸ‘€πŸŒ± Congrats Xu et al.

Lab leaders wrestle with paucity of postdocs Nature - Even high-profile scientists are struggling to recruit qualified postdoctoral researchers.

And is not getting any better in the near future.
