KIF2C-induced nuclear condensation concentrates PLK1 and phosphorylated BRCA2 at the kinetochore microtubules in mitosis

A. Skobelkina, M. Julien, S. Jeannin, S. Miron, T. Egger, R. Chaaban, G. Bouvignies, R. Ghouil, C. Friel, D. BUSSO, F.-X. Theillet, R. Le Bars, A. Carreira, A. Constantinou, J. Basbous, S. ZINN-JUSTIN

The paper shows KIF2C forms condensates during mitosis that concentrate PLK1 and phosphorylated BRCA2 at kinetochore microtubules, enhancing their kinase activity and attachment stability.

Bradyrhizobium diazoefficiens USDA110 nodulation of Aeschynomene afraspera is associated with atypical terminal bacteroid differentiation and suboptimal symbiotic efficiency

Q. Nicoud, F. Lamouche, A. Chaumeret, T. Balliau, R. Le Bars, M. Bourge, F. Pierre, F. Guerard, E. Sallet, S. Tuffigo, O. Pierre, Y. Dessaux, F. Gilard, B. Gakiere, I. Nagy, , B. Alunni

This study shows that Bradyrhizobium diazoefficiens USDA110 forms a functional but inefficient symbiosis with Aeschynomene afraspera due to atypical terminal bacteroid differentiation.
