Hyperosmolarity-induced suppression of group B1 Raf-like protein kinases modulates drought-growth trade-off in Arabidopsis

Y. Kamiyama, S. Katagiri, K. Yamashita, Y. Li, H. Takase, T. Umezawa

The paper identifies Raf13 and IREH1 as growth-promoting kinases suppressed by PP2A under drought stress, modulating the growth-stress trade-off in Arabidopsis.

Activation of SnRK2 by the Raf-like kinase ARK represents a common mechanism of ABA response in embryophytes

D. Takezawa, M. Islam, T. Inoue, M. Hiraide, N. Khatun, A. Jahan, K. Kuwata, T. Umezawa, I. Yotsui, Y. Sakata

The paper identifies Ser1029 phosphorylation as critical for ARK activation in ABA response, showing its role in SnRK2 regulation and stress tolerance in moss.

SNF1-related protein kinase 2 directly regulate group C Raf-like protein kinases in abscisic acid signaling

Y. Kamiyama, M. Hirotani, S. Ishikawa, F. Minegishi, S. Katagiri, F. Takahashi, M. Nomoto, K. Ishikawa, Y. Kodama, Y. Tada, D. Takezawa, S. C. Peck, K. Shinozaki, T. Umezawa

This study identifies Raf36 as a SnRK2-interacting kinase that negatively regulates ABA responses and is directly phosphorylated by SnRK2s, revealing a new phosphosignaling pathway in ABA signaling.
