Companion cells with high florigen production express other small proteins and reveal a nitrogen-sensitive FT repressor

Hiroshi Takagi, Shogo Ito, Jae Sung Shim, Akane Kubota, Andrew K Hempton, Nayoung Lee, Takamasa Suzuki, Jared S. Wong, Chansie Yang, Christine T Nolan, Kerry L. Bubb, Cristina M Alexandre, Daisuke Kurihara, Yoshikatsu Sato, Yasuomi Tada, , Takato Imaizumi

The paper identifies FT-expressing companion cells in leaves, reveals their unique gene expression profile, and shows that NIGT1 represses FT under nitrogen-rich conditions.
