ARF3-mediated auxin signaling is essential for sex determination in cucumber Sex determination underpins genesis of male and female flowers with particularly important implications in plant breeding. Auxin and ethylene regulate femaleness in cucurbits. Here, we identified an a...

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.

Structures and mechanisms of the Arabidopsis cytokinin transporter AZG1 - Nature Plants Xu et al. report structures of the Arabidopsis cytokinin importer AZG1 in the apo, trans-zeatin-bound, 6-benzyleaminopurine-bound and kinetin-bound states, and elucidate an elevator transport model fo...

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 👀🌱 Congrats Xu et al.

I can't think of a more rewarding genetic study. To reconstitute the identity of a person after 46 years, when dictatorship stole babies after disappearing their parents. This happened 132 time already in Argentina thanks to @abuelasdifusion ❤️ Keep pipetting, go science 🧬 📝👇🏼

A smile that will last for 4 years💙🤍💙 Thanks @AlexisMaizel you behaved like a true (ex)Champ 🤝🏆⚽

What a wonderful @sfb1101 retreat we just had! Truly inspiring to witness the development of collaborative projects from @uni_tue @ZMBP_Tuebingen, @MPI_Bio, @UniHohenheim and @UniHeidelberg @COSHeidelberg

An incredible @COSHeidelberg symposium just came to an end. Great talks, discussions and asado in the beautiful Heidelberg. ,🤓🌱🐟🪱🧬

And is not getting any better in the near future.

I cannot be happier after the #Proteomics bioinformatics course at @EBItraining. That was a great week! Leaving with lots of new friend and so many new ideas 💡🌿

Yesterday I completed my first day as @AvHStiftung GF fellow at the @AlexisMaizel lab. Honored to be part and thankful for allowing my ideas come true at the bench. Looking forward to sharing the first insights with 🤓🌱🧬

No, no está bien. Está muy bien 😁

If you ask me, this is an extraordinary opportunity! Come join the lab to learn a looot and have a great time in a great city! See you next year ;

Ni hablar de que el vuelo que nos ofrecen es aprox. 50% mas barato del que compramos originalmente. (FRA-COR vs FRA-EZE).

Nahhh, lo feliz que me pone este tweet! Más merecido que la copa a Messi. Gran día para las plantas y la ciencia. Abrazo gigante al gran @nachol15 🤓🌱

Btw, does real life Peter Brodersen also look like Christian Bale or is a Zoom filter? 😁

This has been a different @rafv2021 but still an excellent meeting. Congrats to all organizers esp. to @manavellalab! Here's a pic of how it felt for me. The little one rising hands to ask @arg_epilab after a great Peter Brodersen's talk 🌱🥰

Se te va a extrañar mucho Nico!
